VS Code API
VS Code API is a set of JavaScript APIs that you can invoke in your Visual Studio Code extension. This page lists all VS Code APIs available to extension authors.
API namespaces and classes
This listing is compiled from the vscode.d.ts file from the VS Code repository.
authentication
Events
onDidChangeSessions: Event<AuthenticationSessionsChangeEvent>
An Event which fires when the authentication sessions of an authentication provider have been added, removed, or changed.
Functions
getAccounts(providerId: string): Thenable<readonly AuthenticationSessionAccountInformation[]>
Get all accounts that the user is logged in to for the specified provider. Use this paired with getSession in order to get an authentication session for a specific account.
Currently, there are only two authentication providers that are contributed from built in extensions to the editor that implement GitHub and Microsoft authentication: their providerId's are 'github' and 'microsoft'.
Note: Getting accounts does not imply that your extension has access to that account or its authentication sessions. You can verify access to the account by calling getSession.
Parameter | Description |
---|---|
providerId: string | The id of the provider to use |
Returns | Description |
Thenable<readonly AuthenticationSessionAccountInformation[]> | A thenable that resolves to a readonly array of authentication accounts. |
getSession(providerId: string, scopes: readonly string[], options: AuthenticationGetSessionOptions & {createIfNone: true}): Thenable<AuthenticationSession>
Get an authentication session matching the desired scopes. Rejects if a provider with providerId is not registered, or if the user does not consent to sharing authentication information with the extension. If there are multiple sessions with the same scopes, the user will be shown a quickpick to select which account they would like to use.

commands
Namespace for dealing with commands. In short, a command is a function with a unique identifier. The function is sometimes also called command handler.
Commands can be added to the editor using the registerCommand and registerTextEditorCommand functions. Commands can be executed manually or from a UI gesture. Those are:
- palette - Use the
commands
-section inpackage.json
to make a command show in the command palette. - keybinding - Use the
keybindings
-section inpackage.json
to enable keybindings for your extension.
Commands from other extensions and from the editor itself are accessible to an extension. However, when invoking an editor command not all argument types are supported.
This is a sample that registers a command handler and adds an entry for that command to the palette. First
register a command handler with the identifier extension.sayHello
.
commands.registerCommand('extension.sayHello', () => {
window.showInformationMessage('Hello World!');
});
Second, bind the command identifier to a title under which it will show in the palette (package.json
).
{
"contributes": {
"commands": [
{
"command": "extension.sayHello",
"title": "Hello World"
}
]
}
}
Functions
executeCommand<T>(command: string, ...rest: any[]): Thenable<T>
Executes the command denoted by the given command identifier.
- Note 1: When executing an editor command not all types are allowed to
be passed as arguments. Allowed are the primitive types
string
,boolean
,number
,undefined
, andnull
, as well as Position, Range, Uri and Location. - Note 2: There are no restrictions when executing commands that have been contributed by extensions.
Parameter | Description |
---|---|
command: string | Identifier of the command to execute. |
...rest: any[] | Parameters passed to the command function. |
Returns | Description |
Thenable<T> | A thenable that resolves to the returned value of the given command. Returns |

Returns | Description |
void |
asDebugSourceUri(source: DebugProtocolSource, session?: DebugSession): Uri
Converts a "Source" descriptor object received via the Debug Adapter Protocol into a Uri that can be used to load its contents. If the source descriptor is based on a path, a file Uri is returned. If the source descriptor uses a reference number, a specific debug Uri (scheme 'debug') is constructed that requires a corresponding ContentProvider and a running debug session
If the "Source" descriptor has insufficient information for creating the Uri, an error is thrown.
Parameter | Description |
---|---|
source: DebugProtocolSource | An object conforming to the Source type defined in the Debug Adapter Protocol. |
session?: DebugSession | An optional debug session that will be used when the source descriptor uses a reference number to load the contents from an active debug session. |
Returns | Description |
Uri | A uri that can be used to load the contents of the source. |
registerDebugAdapterDescriptorFactory(debugType: string, factory: DebugAdapterDescriptorFactory): Disposable
Register a debug adapter descriptor factory for a specific debug type. An extension is only allowed to register a DebugAdapterDescriptorFactory for the debug type(s) defined by the extension. Otherwise an error is thrown. Registering more than one DebugAdapterDescriptorFactory for a debug type results in an error.
Parameter | Description |
---|---|
debugType: string | The debug type for which the factory is registered. |
factory: DebugAdapterDescriptorFactory | The debug adapter descriptor factory to register. |
Returns | Description |
Disposable | A Disposable that unregisters this factory when being disposed. |
registerDebugAdapterTrackerFactory(debugType: string, factory: DebugAdapterTrackerFactory): Disposable
Register a debug adapter tracker factory for the given debug type.
Parameter | Description |
---|---|
debugType: string | The debug type for which the factory is registered or '*' for matching all debug types. |
factory: DebugAdapterTrackerFactory | The debug adapter tracker factory to register. |
Returns | Description |
Disposable | A Disposable that unregisters this factory when being disposed. |
registerDebugConfigurationProvider(debugType: string, provider: DebugConfigurationProvider, triggerKind?: DebugConfigurationProviderTriggerKind): Disposable
Register a debug configuration provider for a specific debug type.
The optional triggerKind can be used to specify when the provideDebugConfigurations
method of the provider is triggered.
Currently two trigger kinds are possible: with the value Initial
(or if no trigger kind argument is given) the provideDebugConfigurations
method is used to provide the initial debug configurations to be copied into a newly created launch.json.
With the trigger kind Dynamic
the provideDebugConfigurations
method is used to dynamically determine debug configurations to be presented to the user (in addition to the static configurations from the launch.json).
Please note that the triggerKind
argument only applies to the provideDebugConfigurations
method: so the resolveDebugConfiguration
methods are not affected at all.
Registering a single provider with resolve methods for different trigger kinds, results in the same resolve methods called multiple times.
More than one provider can be registered for the same type.
Parameter | Description |
---|---|
debugType: string | The debug type for which the provider is registered. |
provider: DebugConfigurationProvider | The debug configuration provider to register. |
triggerKind?: DebugConfigurationProviderTriggerKind | The trigger for which the 'provideDebugConfiguration' method of the provider is registered. If |
Returns | Description |
Disposable | A Disposable that unregisters this provider when being disposed. |

session?: DebugSession | The debug session to stop; if omitted all sessions are stopped. |
Returns | Description |
Thenable<void> | A thenable that resolves when the session(s) have been stopped. |
env
Namespace describing the environment the editor runs in.
Variables
The hosted location of the application On desktop this is 'desktop' In the web this is the specified embedder i.e. 'github.dev', 'codespaces', or 'web' if the embedder does not provide that information
The application name of the editor, like 'VS Code'.
The application root folder from which the editor is running.
Note that the value is the empty string when running in an environment that has no representation of an application root folder.
clipboard: Clipboard
The system clipboard.
Indicates that this is a fresh install of the application.
true
if within the first day of installation otherwise false
.
Indicates whether the users has telemetry enabled. Can be observed to determine if the extension should send telemetry.
Represents the preferred user-language, like de-CH
, fr
, or en-US
.
logLevel: LogLevel
The current log level of the editor.
A unique identifier for the computer.
remoteName: string | undefined
The name of a remote. Defined by extensions, popular samples are wsl
for the Windows
Subsystem for Linux or ssh-remote
for remotes using a secure shell.
Note that the value is undefined
when there is no remote extension host but that the
value is defined in all extension hosts (local and remote) in case a remote extension host
exists. Use Extension.extensionKind to know if
a specific extension runs remote or not.
A unique identifier for the current session. Changes each time the editor is started.
The detected default shell for the extension host, this is overridden by the
terminal.integrated.defaultProfile
setting for the extension host's platform. Note that in
environments that do not support a shell the value is the empty string.
uiKind: UIKind
The UI kind property indicates from which UI extensions are accessed from. For example, extensions could be accessed from a desktop application or a web browser.
The custom uri scheme the editor registers to in the operating system.
Events
onDidChangeLogLevel: Event<LogLevel>
An Event which fires when the log level of the editor changes.
onDidChangeShell: Event<string>
An Event which fires when the default shell changes. This fires with the new shell path.
onDidChangeTelemetryEnabled: Event<boolean>
An Event which fires when the user enabled or disables telemetry.
true
if the user has enabled telemetry or false
if the user has disabled telemetry.
Functions
asExternalUri(target: Uri): Thenable<Uri>
Resolves a uri to a form that is accessible externally.
http:
or https:
scheme
Resolves an external uri, such as a http:
or https:
link, from where the extension is running to a
uri to the same resource on the client machine.
This is a no-op if the extension is running on the client machine.
If the extension is running remotely, this function automatically establishes a port forwarding tunnel
from the local machine to target
on the remote and returns a local uri to the tunnel. The lifetime of
the port forwarding tunnel is managed by the editor and the tunnel can be closed by the user.
Note that uris passed through openExternal
are automatically resolved and you should not call asExternalUri
on them.
vscode.env.uriScheme
Creates a uri that - if opened in a browser (e.g. via openExternal
) - will result in a registered UriHandler
to trigger.
Extensions should not make any assumptions about the resulting uri and should not alter it in any way. Rather, extensions can e.g. use this uri in an authentication flow, by adding the uri as callback query argument to the server to authenticate to.
Note that if the server decides to add additional query parameters to the uri (e.g. a token or secret), it will appear in the uri that is passed to the UriHandler.
Example of an authentication flow:
vscode.window.registerUriHandler({
handleUri(uri: vscode.Uri): vscode.ProviderResult<void> {
if (uri.path === '/did-authenticate') {
console.log(uri.toString());
}
}
});
const callableUri = await vscode.env.asExternalUri(
vscode.Uri.parse(vscode.env.uriScheme + '://my.extension/did-authenticate')
);
await vscode.env.openExternal(callableUri);
Note that extensions should not cache the result of asExternalUri
as the resolved uri may become invalid due to
a system or user action — for example, in remote cases, a user may close a port forwarding tunnel that was opened by
asExternalUri
.
Any other scheme
Any other scheme will be handled as if the provided URI is a workspace URI. In that case, the method will return a URI which, when handled, will make the editor open the workspace.
createTelemetryLogger(sender: TelemetrySender, options?: TelemetryLoggerOptions): TelemetryLogger
Creates a new telemetry logger.
Parameter | Description |
---|---|
sender: TelemetrySender | The telemetry sender that is used by the telemetry logger. |
options?: TelemetryLoggerOptions | Options for the telemetry logger. |
Returns | Description |
TelemetryLogger | A new telemetry logger |
openExternal(target: Uri): Thenable<boolean>
Opens a link externally using the default application. Depending on the used scheme this can be:
- a browser (
http:
,https:
) - a mail client (
mailto:
) - VSCode itself (
vscode:
fromvscode.env.uriScheme
)
Note that showTextDocument is the right way to open a text document inside the editor, not this function.
Parameter | Description |
---|---|
target: Uri | The uri that should be opened. |
Returns | Description |
Thenable<boolean> | A promise indicating if open was successful. |
extensions
Namespace for dealing with installed extensions. Extensions are represented by an Extension-interface which enables reflection on them.
Extension writers can provide APIs to other extensions by returning their API public
surface from the activate
-call.
export function activate(context: vscode.ExtensionContext) {
let api = {
sum(a, b) {
return a + b;
},
mul(a, b) {
return a * b;
}
};
// 'export' public api-surface
return api;
}
When depending on the API of another extension add an extensionDependencies
-entry
to package.json
, and use the getExtension-function
and the exports-property, like below:
let mathExt = extensions.getExtension('genius.math');
let importedApi = mathExt.exports;
console.log(importedApi.mul(42, 1));
Variables
all: readonly Extension<any>[]
All extensions currently known to the system.
Events
onDidChange: Event<void>
An event which fires when extensions.all
changes. This can happen when extensions are
installed, uninstalled, enabled or disabled.
Functions
getExtension<T>(extensionId: string): Extension<T> | undefined

.
Parameter | Description |
---|---|
extensionId: string | An extension identifier. |
Returns | Description |
Extension<T> | undefined | An extension or |
l10n
Namespace for localization-related functionality in the extension API. To use this properly,
you must have l10n
defined in your extension manifest and have bundle.l10n.
Note: Built-in extensions (for example, Git, TypeScript Language Features, GitHub Authentication)
are excluded from the l10n
property requirement. In other words, they do not need to specify
a l10n
in the extension manifest because their translated strings come from Language Packs.
Variables
The bundle of localized strings that have been loaded for the extension. It's undefined if no bundle has been loaded. The bundle is typically not loaded if there was no bundle found or when we are running with the default language.
uri: Uri | undefined
The URI of the localization bundle that has been loaded for the extension. It's undefined if no bundle has been loaded. The bundle is typically not loaded if there was no bundle found or when we are running with the default language.
Functions
t(message: string, ...args: Array<string | number | boolean>): string
Marks a string for localization. If a localized bundle is available for the language specified by env.language and the bundle has a localized value for this message, then that localized value will be returned (with injected args values for any templated values).
Example
l10n.t('Hello {0}!', 'World');
Parameter | Description |
---|---|
message: string | The message to localize. Supports index templating where strings like |
...args: Array<string | number | boolean> | The arguments to be used in the localized string. The index of the argument is used to match the template placeholder in the localized string. |
Returns | Description |
string | localized string with injected arguments. |
t(message: string, args: Record<string, any>): string
Marks a string for localization. If a localized bundle is available for the language specified by env.language and the bundle has a localized value for this message, then that localized value will be returned (with injected args values for any templated values).
Example
l10n.t('Hello {name}', { name: 'Erich' });
Parameter | Description |
---|---|
message: string | The message to localize. Supports named templating where strings like |
args: Record<string, any> | The arguments to be used in the localized string. The name of the key in the record is used to match the template placeholder in the localized string. |
Returns | Description |
string | localized string with injected arguments. |
t(options: {args: Array<string | number | boolean> | Record<string, any>, comment: string | string[], message: string}): string
Marks a string for localization. If a localized bundle is available for the language specified by env.language and the bundle has a localized value for this message, then that localized value will be returned (with injected args values for any templated values).
Parameter | Description |
---|---|
options: {args: Array<string | number | boolean> | Record<string, any>, comment: string | string[], message: string} | The options to use when localizing the message. |
Returns | Description |
string | localized string with injected arguments. |
languages
Namespace for participating in language-specific editor features, like IntelliSense, code actions, diagnostics etc.
Many programming languages exist and there is huge variety in syntaxes, semantics, and paradigms. Despite that, features like automatic word-completion, code navigation, or code checking have become popular across different tools for different programming languages.
The editor provides an API that makes it simple to provide such common features by having all UI and actions already in place and by allowing you to participate by providing data only. For instance, to contribute a hover all you have to do is provide a function that can be called with a TextDocument and a Position returning hover info. The rest, like tracking the mouse, positioning the hover, keeping the hover stable etc. is taken care of by the editor.
languages.registerHoverProvider('javascript', {
provideHover(document, position, token) {
return new Hover('I am a hover!');
}
});
Registration is done using a document selector which is either a language id, like javascript
or
a more complex filter like { language: 'typescript', scheme: 'file' }
. Matching a document against such
a selector will result in a score that is used to determine if and how a provider shall be used. When
scores are equal the provider that came last wins. For features that allow full arity, like hover,
the score is only checked to be >0
, for other features, like IntelliSense the
score is used for determining the order in which providers are asked to participate.

match(selector: DocumentSelector, document: TextDocument): number
Compute the match between a document selector and a document. Values greater than zero mean the selector matches the document.
A match is computed according to these rules:
- When DocumentSelector is an array, compute the match for each contained
DocumentFilter
or language identifier and take the maximum value. - A string will be desugared to become the
language
-part of a DocumentFilter, so"fooLang"
is like{ language: "fooLang" }
. - A DocumentFilter will be matched against the document by comparing its parts with the document. The following rules apply:
- When the
DocumentFilter
is empty ({}
) the result is0
- When
scheme
,language
,pattern
, ornotebook
are defined but one doesn't match, the result is0
- Matching against
*
gives a score of5
, matching via equality or via a glob-pattern gives a score of10
- The result is the maximum value of each match
- When the
Samples:
// default document from disk (file-scheme)
doc.uri; //'file:///my/file.js'
doc.languageId; // 'javascript'
match('javascript', doc); // 10;

prompt-tsx-parts. If the tool caller is using vscode/prompt-tsx
, it can
incorporate the response parts into its prompt using a ToolResult
. If not, the parts can be passed along to the
LanguageModelChat via a user message with a LanguageModelToolResultPart.

workspace
Namespace for dealing with the current workspace. A workspace is the collection of one or more folders that are opened in an editor window (instance).
It is also possible to open an editor without a workspace. For example, when you open a new editor window by selecting a file from your platform's File menu, you will not be inside a workspace. In this mode, some of the editor's capabilities are reduced but you can still open text files and edit them.
Refer to https://code.visualstudio.com/docs/editor/workspaces for more information on the concept of workspaces.
The workspace offers support for listening to fs events and for finding files. Both perform well and run outside the editor-process so that they should be always used instead of nodejs-equivalents.
Variables
fs: FileSystem
A file system instance that allows to interact with local and remote
files, e.g. vscode.workspace.fs.readDirectory(someUri)
allows to retrieve all entries
of a directory or vscode.workspace.fs.stat(anotherUri)
returns the meta data for a
file.
When true, the user has explicitly trusted the contents of the workspace.
The name of the workspace. undefined
when no workspace
has been opened.
Refer to https://code.visualstudio.com/docs/editor/workspaces for more information on the concept of workspaces.
notebookDocuments: readonly NotebookDocument[]
All notebook documents currently known to the editor.
The uri of the first entry of workspaceFolders
as string
. undefined
if there is no first entry.
Refer to https://code.visualstudio.com/docs/editor/workspaces for more information on workspaces.
- deprecated - Use workspaceFolders instead.
textDocuments: readonly TextDocument[]
All text documents currently known to the editor.
workspaceFile: Uri | undefined
The location of the workspace file, for example:
file:///Users/name/Development/myProject.code-workspace
or
untitled:1555503116870
for a workspace that is untitled and not yet saved.
Depending on the workspace that is opened, the value will be:
undefined
when no workspace is opened- the path of the workspace file as
Uri
otherwise. if the workspace is untitled, the returned URI will use theuntitled:
scheme
The location can e.g. be used with the vscode.openFolder
command to
open the workspace again after it has been closed.
Example:
vscode.commands.executeCommand('vscode.openFolder', uriOfWorkspace);
Refer to https://code.visualstudio.com/docs/editor/workspaces for more information on the concept of workspaces.
Note: it is not advised to use workspace.workspaceFile
to write
configuration data into the file. You can use workspace.getConfiguration().update()
for that purpose which will work both when a single folder is opened as
well as an untitled or saved workspace.
workspaceFolders: readonly WorkspaceFolder[] | undefined
List of workspace folders (0-N) that are open in the editor. undefined
when no workspace
has been opened.
Refer to https://code.visualstudio.com/docs/editor/workspaces for more information on workspaces.
Events
onDidChangeConfiguration: Event<ConfigurationChangeEvent>
An event that is emitted when the configuration changed.
onDidChangeNotebookDocument: Event<NotebookDocumentChangeEvent>
An event that is emitted when a notebook has changed.
onDidChangeTextDocument: Event<TextDocumentChangeEvent>
An event that is emitted when a text document is changed. This usually happens when the contents changes but also when other things like the dirty-state changes.
onDidChangeWorkspaceFolders: Event<WorkspaceFoldersChangeEvent>
An event that is emitted when a workspace folder is added or removed.
Note: this event will not fire if the first workspace folder is added, removed or changed,
because in that case the currently executing extensions (including the one that listens to this
event) will be terminated and restarted so that the (deprecated) rootPath
property is updated
to point to the first workspace folder.
onDidCloseNotebookDocument: Event<NotebookDocument>
An event that is emitted when a notebook is disposed.
Note 1: There is no guarantee that this event fires when an editor tab is closed.
Note 2: A notebook can be open but not shown in an editor which means this event can fire for a notebook that has not been shown in an editor.
onDidCloseTextDocument: Event<TextDocument>
An event that is emitted when a text document is disposed or when the language id of a text document has been changed.
Note 1: There is no guarantee that this event fires when an editor tab is closed, use the onDidChangeVisibleTextEditors-event to know when editors change.
Note 2: A document can be open but not shown in an editor which means this event can fire for a document that has not been shown in an editor.
onDidCreateFiles: Event<FileCreateEvent>
An event that is emitted when files have been created.
Note: This event is triggered by user gestures, like creating a file from the explorer, or from the workspace.applyEdit-api, but this event is not fired when files change on disk, e.g triggered by another application, or when using the workspace.fs-api.
onDidDeleteFiles: Event<FileDeleteEvent>
An event that is emitted when files have been deleted.
Note 1: This event is triggered by user gestures, like deleting a file from the explorer, or from the workspace.applyEdit-api, but this event is not fired when files change on disk, e.g triggered by another application, or when using the workspace.fs-api.
Note 2: When deleting a folder with children only one event is fired.
onDidGrantWorkspaceTrust: Event<void>
Event that fires when the current workspace has been trusted.
onDidOpenNotebookDocument: Event<NotebookDocument>
An event that is emitted when a notebook is opened.
onDidOpenTextDocument: Event<TextDocument>
An event that is emitted when a text document is opened or when the language id of a text document has been changed.
To add an event listener when a visible text document is opened, use the TextEditor events in the window namespace. Note that:
- The event is emitted before the document is updated in the active text editor
- When a text document is already open (e.g.: open in another visible text editor) this event is not emitted
onDidRenameFiles: Event<FileRenameEvent>
An event that is emitted when files have been renamed.
Note 1: This event is triggered by user gestures, like renaming a file from the explorer, and from the workspace.applyEdit-api, but this event is not fired when files change on disk, e.g triggered by another application, or when using the workspace.fs-api.
Note 2: When renaming a folder with children only one event is fired.
onDidSaveNotebookDocument: Event<NotebookDocument>
An event that is emitted when a notebook is saved.
onDidSaveTextDocument: Event<TextDocument>
An event that is emitted when a text document is saved to disk.
onWillCreateFiles: Event<FileWillCreateEvent>
An event that is emitted when files are being created.
Note 1: This event is triggered by user gestures, like creating a file from the explorer, or from the workspace.applyEdit-api. This event is not fired when files change on disk, e.g triggered by another application, or when using the workspace.fs-api.
Note 2: When this event is fired, edits to files that are are being created cannot be applied.
onWillDeleteFiles: Event<FileWillDeleteEvent>
An event that is emitted when files are being deleted.
Note 1: This event is triggered by user gestures, like deleting a file from the explorer, or from the workspace.applyEdit-api, but this event is not fired when files change on disk, e.g triggered by another application, or when using the workspace.fs-api.
Note 2: When deleting a folder with children only one event is fired.

Note 2: When renaming a folder with children only one event is fired.
onWillSaveNotebookDocument: Event<NotebookDocumentWillSaveEvent>
An event that is emitted when a notebook document will be saved to disk.
Note 1: Subscribers can delay saving by registering asynchronous work. For the sake of data integrity the editor might save without firing this event. For instance when shutting down with dirty files.
Note 2: Subscribers are called sequentially and they can delay saving by registering asynchronous work. Protection against misbehaving listeners is implemented as such:
- there is an overall time budget that all listeners share and if that is exhausted no further listener is called
- listeners that take a long time or produce errors frequently will not be called anymore
The current thresholds are 1.5 seconds as overall time budget and a listener can misbehave 3 times before being ignored.
onWillSaveTextDocument: Event<TextDocumentWillSaveEvent>
An event that is emitted when a text document will be saved to disk.

Functions
applyEdit(edit: WorkspaceEdit, metadata?: WorkspaceEditMetadata): Thenable<boolean>
Make changes to one or many resources or create, delete, and rename resources as defined by the given workspace edit.
All changes of a workspace edit are applied in the same order in which they have been added. If multiple textual inserts are made at the same position, these strings appear in the resulting text in the order the 'inserts' were made, unless that are interleaved with resource edits. Invalid sequences like 'delete file a' -> 'insert text in file a' cause failure of the operation.
When applying a workspace edit that consists only of text edits an 'all-or-nothing'-strategy is used. A workspace edit with resource creations or deletions aborts the operation, e.g. consecutive edits will not be attempted, when a single edit fails.
Parameter | Description |
---|---|
edit: WorkspaceEdit | A workspace edit. |
metadata?: WorkspaceEditMetadata | Optional metadata for the edit. |
Returns | Description |
Thenable<boolean> | A thenable that resolves when the edit could be applied. |
asRelativePath(pathOrUri: string | Uri, includeWorkspaceFolder?: boolean): string
Returns a path that is relative to the workspace folder or folders.
When there are no workspace folders or when the path is not contained in them, the input is returned.
Parameter | Description |
---|---|
pathOrUri: string | Uri | A path or uri. When a uri is given its fsPath is used. |
includeWorkspaceFolder?: boolean | When |
Returns | Description |
string | A path relative to the root or the input. |
createFileSystemWatcher(globPattern: GlobPattern, ignoreCreateEvents?: boolean, ignoreChangeEvents?: boolean, ignoreDeleteEvents?: boolean): FileSystemWatcher
Creates a file system watcher that is notified on file events (create, change, delete) depending on the parameters provided.
By default, all opened workspace folders will be watched for file changes recursively.
Additional paths can be added for file watching by providing a RelativePattern with
a base
path to watch. If the path is a folder and the pattern
is complex (e.g. contains
**
or path segments), it will be watched recursively and otherwise will be watched
non-recursively (i.e. only changes to the first level of the path will be reported).
Note that paths that do not exist in the file system will be monitored with a delay until created and then watched depending on the parameters provided. If a watched path is deleted, the watcher will suspend and not report any events until the path is created again.
If possible, keep the use of recursive watchers to a minimum because recursive file watching is quite resource intense.
Providing a string
as globPattern
acts as convenience method for watching file events in
all opened workspace folders. It cannot be used to add more folders for file watching, nor will
it report any file events from folders that are not part of the opened workspace folders.
Optionally, flags to ignore certain kinds of events can be provided.
To stop listening to events the watcher must be disposed.
Note that file events from recursive file watchers may be excluded based on user configuration.
The setting files.watcherExclude
helps to reduce the overhead of file events from folders
that are known to produce many file changes at once (such as .git
folders). As such,
it is highly recommended to watch with simple patterns that do not require recursive watchers
where the exclude settings are ignored and you have full control over the events.
Note that symbolic links are not automatically followed for file watching unless the path to watch itself is a symbolic link.
Note that the file paths that are reported for having changed may have a different path casing compared to the actual casing on disk on case-insensitive platforms (typically macOS and Windows but not Linux). We allow a user to open a workspace folder with any desired path casing and try to preserve that. This means:
- if the path is within any of the workspace folders, the path will match the casing of the workspace folder up to that portion of the path and match the casing on disk for children
- if the path is outside of any of the workspace folders, the casing will match the case of the path that was provided for watching In the same way, symbolic links are preserved, i.e. the file event will report the path of the symbolic link as it was provided for watching and not the target.
Examples
The basic anatomy of a file watcher is as follows:
const watcher = vscode.workspace.createFileSystemWatcher(new vscode.RelativePattern(<folder>, <pattern>));
watcher.onDidChange(uri => { ... }); // listen to files being changed
watcher.onDidCreate(uri => { ... }); // listen to files/folders being created
watcher.onDidDelete(uri => { ... }); // listen to files/folders getting deleted
watcher.dispose(); // dispose after usage
Workspace file watching
If you only care about file events in a specific workspace folder:
vscode.workspace.createFileSystemWatcher(
new vscode.RelativePattern(vscode.workspace.workspaceFolders[0], '**/*.js')
);
If you want to monitor file events across all opened workspace folders:
vscode.workspace.createFileSystemWatcher('**/*.js');
Note: the array of workspace folders can be empty if no workspace is opened (empty window).
Out of workspace file watching
To watch a folder for changes to *.js files outside the workspace (non recursively), pass in a Uri
to such
a folder:
vscode.workspace.createFileSystemWatcher(new vscode.RelativePattern(vscode.Uri.file(<path to folder outside workspace>), '*.js'));
And use a complex glob pattern to watch recursively:
vscode.workspace.createFileSystemWatcher(new vscode.RelativePattern(vscode.Uri.file(<path to folder outside workspace>), '**/*.js'));
Here is an example for watching the active editor for file changes:
vscode.workspace.createFileSystemWatcher(
new vscode.RelativePattern(vscode.window.activeTextEditor.document.uri, '*')
);
Parameter | Description |
---|---|
globPattern: GlobPattern | A glob pattern that controls which file events the watcher should report. |

updateWorkspaceFolders(start: number, deleteCount: number, ...workspaceFoldersToAdd: Array<{name: string, uri: Uri}>): boolean
This method replaces deleteCount
workspace folders starting at index start
by an optional set of workspaceFoldersToAdd
on the vscode.workspace.workspaceFolders
array. This "splice"
behavior can be used to add, remove and change workspace folders in a single operation.
Note: in some cases calling this method may result in the currently executing extensions (including the
one that called this method) to be terminated and restarted. For example when the first workspace folder is
added, removed or changed the (deprecated) rootPath
property is updated to point to the first workspace
folder. Another case is when transitioning from an empty or single-folder workspace into a multi-folder
workspace (see also: https://code.visualstudio.com/docs/editor/workspaces).
Use the onDidChangeWorkspaceFolders() event to get notified when the workspace folders have been updated.
Example: adding a new workspace folder at the end of workspace folders
workspace.updateWorkspaceFolders(workspace.workspaceFolders ? workspace.workspaceFolders.length : 0, null, { uri: ...});
Example: removing the first workspace folder
workspace.updateWorkspaceFolders(0, 1);
Example: replacing an existing workspace folder with a new one
workspace.updateWorkspaceFolders(0, 1, { uri: ...});
It is valid to remove an existing workspace folder and add it again with a different name to rename that folder.
Note: it is not valid to call updateWorkspaceFolders() multiple times without waiting for the onDidChangeWorkspaceFolders() to fire.
Parameter | Description |
---|---|
start: number | the zero-based location in the list of currently opened workspace folders from which to start deleting workspace folders. |
deleteCount: number | the optional number of workspace folders to remove. |
...workspaceFoldersToAdd: Array<{name: string, uri: Uri}> | the optional variable set of workspace folders to add in place of the deleted ones. Each workspace is identified with a mandatory URI and an optional name. |
Returns | Description |
boolean | true if the operation was successfully started and false otherwise if arguments were used that would result in invalid workspace folder state (e.g. 2 folders with the same URI). |
AccessibilityInformation
Accessibility information which controls screen reader behavior.
Properties
Label to be read out by a screen reader once the item has focus.

If role is not specified the editor will pick the appropriate role automatically. More about aria roles can be found here https://w3c.github.io/aria/#widget_roles
AuthenticationForceNewSessionOptions
Optional options to be used when calling authentication.getSession with the flag forceNewSession
.
Properties
An optional message that will be displayed to the user when we ask to re-authenticate. Providing additional context as to why you are asking a user to re-authenticate can help increase the odds that they will accept.
AuthenticationGetSessionOptions
Options to be used when getting an AuthenticationSession from an AuthenticationProvider.
Properties
account?: AuthenticationSessionAccountInformation
The account that you would like to get a session for. This is passed down to the Authentication Provider to be used for creating the correct session.
clearSessionPreference?: boolean
Whether the existing session preference should be cleared.
For authentication providers that support being signed into multiple accounts at once, the user will be prompted to select an account to use when getSession is called. This preference is remembered until getSession is called with this flag.
Note: The preference is extension specific. So if one extension calls getSession, it will not affect the session preference for another extension calling getSession. Additionally, the preference is set for the current workspace and also globally. This means that new workspaces will use the "global" value at first and then when this flag is provided, a new value can be set for that workspace. This also means that pre-existing workspaces will not lose their preference if a new workspace sets this flag.
Defaults to false.
Whether login should be performed if there is no matching session.
If true, a modal dialog will be shown asking the user to sign in. If false, a numbered badge will be shown on the accounts activity bar icon. An entry for the extension will be added under the menu to sign in. This allows quietly prompting the user to sign in.
If there is a matching session but the extension has not been granted access to it, setting this to true will also result in an immediate modal dialog, and false will add a numbered badge to the accounts icon.
Defaults to false.
Note: you cannot use this option with silent.
forceNewSession?: boolean | AuthenticationForceNewSessionOptions
Whether we should attempt to reauthenticate even if there is already a session available.
If true, a modal dialog will be shown asking the user to sign in again. This is mostly used for scenarios where the token needs to be re minted because it has lost some authorization.
If there are no existing sessions and forceNewSession is true, it will behave identically to createIfNone.
This defaults to false.
Whether we should show the indication to sign in in the Accounts menu.
If false, the user will be shown a badge on the Accounts menu with an option to sign in for the extension. If true, no indication will be shown.
Defaults to false.
Note: you cannot use this option with any other options that prompt the user like createIfNone.

range?: [start: number, end: number]
The start and end index of the reference in the prompt. When undefined, the reference was not part of the prompt text.
Note that the indices take the leading #
-character into account which means they can be used to modify the prompt
as-is.
ChatParticipant
A chat participant can be invoked by the user in a chat session, using the prefix. When it is invoked, it handles the chat request and is solely
responsible for providing a response to the user. A ChatParticipant is created using chat.createChatParticipant.
Events
onDidReceiveFeedback: Event<ChatResultFeedback>

Note that the [ChatParticipant.name name](#ChatParticipant.name name) of the participant and the [ChatCommand.name command](#ChatCommand.name command) are not part of the prompt.
references: readonly ChatPromptReference[]
The list of references and their values that are referenced in the prompt.
Note that the prompt contains references as authored and that it is up to the participant to further modify the prompt, for instance by inlining reference values or creating links to headings which contain the resolved values. References are sorted in reverse by their range in the prompt. That means the last reference in the prompt is the first in this list. This simplifies string-manipulation of the prompt.

- As commands that users can run, such as
Refactor
. Users can run these from the command palette or with keybindings. - As source actions, such
Organize Imports
. - Quick fixes are shown in the problems view.
- Change applied on save by the
editor.codeActionsOnSave
setting.
Methods
provideCodeActions(document: TextDocument, range: Range | Selection, context: CodeActionContext, token: CancellationToken): ProviderResult<Array<Command | T>>
Get code actions for a given range in a document.
Only return code actions that are relevant to user for the requested range. Also keep in mind how the

CompletionItem
A completion item represents a text snippet that is proposed to complete text that is being typed.
It is sufficient to create a completion item from just a label. In that case the completion item will replace the word until the cursor with the given label or insertText. Otherwise the given edit is used.
When selecting a completion item in the editor its defined or synthesized text edit will be applied to all cursors/selections whereas additionalTextEdits will be applied as provided.

Constructors
new CompletionItem(label: string | CompletionItemLabel, kind?: CompletionItemKind): CompletionItem
Creates a new completion item.
Completion items must have at least a label which then will be used as insert text as well as for sorting and filtering.
Parameter | Description |
---|---|
label: string | CompletionItemLabel | The label of the completion. |
kind?: CompletionItemKind | The kind of the completion. |
Returns | Description |
CompletionItem |
Properties
additionalTextEdits?: TextEdit[]
An optional array of additional text edits that are applied when selecting this completion. Edits must not overlap with the main edit nor with themselves.
command?: Command
An optional Command that is executed after inserting this completion. Note that additional modifications to the current document should be described with the additionalTextEdits-property.
An optional set of characters that when pressed while this completion is active will accept it first and
then type that character. Note that all commit characters should have length=1
and that superfluous
characters will be ignored.
A human-readable string with additional information about this item, like type or symbol information.
documentation?: string | MarkdownString
A human-readable string that represents a doc-comment.
insertText?: string | SnippetString
A string or snippet that should be inserted in a document when selecting
this completion. When falsy
the label
is used.
Keep whitespace of the insertText as is. By default, the editor adjusts leading
whitespace of new lines so that they match the indentation of the line for which the item is accepted - setting
this to true
will prevent that.
kind?: CompletionItemKind
The kind of this completion item. Based on the kind an icon is chosen by the editor.
label: string | CompletionItemLabel
The label of this completion item. By default this is also the text that is inserted when selecting this completion.
Select this item when showing. Note that only one completion item can be selected and that the editor decides which item that is. The rule is that the first item of those that match best is selected.
range?: Range | {inserting: Range, replacing: Range}
A range or a insert and replace range selecting the text that should be replaced by this completion item.
When omitted, the range of the current word is used as replace-range and as insert-range the start of the current word to the current position is used.
Note 1: A range must be a single line and it must contain the position at which completion has been requested. Note 2: A insert range must be a prefix of a replace range, that means it must be contained and starting at the same position.
A string that should be used when comparing this item
with other items. When falsy
the label
is used.
Note that sortText
is only used for the initial ordering of completion
items. When having a leading word (prefix) ordering is based on how
well completions match that prefix and the initial ordering is only used
when completions match equally well. The prefix is defined by the
range-property and can therefore be different
for each completion.
tags?: readonly Deprecated[]
Tags for this completion item.
textEdit?: TextEdit
- deprecated - Use
CompletionItem.insertText
andCompletionItem.range
instead.
An edit which is applied to a document when selecting this completion. When an edit is provided the value of insertText is ignored.
The Range of the edit must be single-line and on the same line completions were requested at.

A structured label for a completion item.
Properties
An optional string which is rendered less prominently after CompletionItemLabel.detail. Should be used for fully qualified names or file path.
An optional string which is rendered less prominently directly after label, without any spacing. Should be used for function signatures or type annotations.
The label of this completion item.
By default this is also the text that is inserted when this completion is selected.
CompletionItemProvider<T>
The completion item provider interface defines the contract between extensions and IntelliSense.
Providers can delay the computation of the detail
and documentation properties by implementing the
resolveCompletionItem-function. However, properties that
are needed for the initial sorting and filtering, like sortText
, filterText
, insertText
, and range
, must
not be changed during resolve.
Providers are asked for completions either explicitly by a user gesture or -depending on the configuration- implicitly when typing words or trigger characters.
Methods
provideCompletionItems(document: TextDocument, position: Position, token: CancellationToken, context: CompletionContext): ProviderResult<CompletionList<T> | T[]>
Provide completion items for the given position and document.
Parameter | Description |
---|---|
document: TextDocument | The document in which the command was invoked. |
position: Position | The position at which the command was invoked. |
token: CancellationToken | A cancellation token. |
context: CompletionContext | How the completion was triggered. |
Returns | Description |
ProviderResult<CompletionList<T> | T[]> | An array of completions, a completion list, or a thenable that resolves to either.
The lack of a result can be signaled by returning |
resolveCompletionItem(item: T, token: CancellationToken): ProviderResult<T>
Given a completion item fill in more data, like doc-comment or details.
The editor will only resolve a completion item once.
Note that this function is called when completion items are already showing in the UI or when an item has been selected for insertion. Because of that, no property that changes the presentation (label, sorting, filtering etc) or the (primary) insert behaviour (insertText) can be changed.
This function may fill in additionalTextEdits. However, that means an item might be inserted before resolving is done and in that case the editor will do a best effort to still apply those additional text edits.
Parameter | Description |
---|---|
item: T | A completion item currently active in the UI. |
token: CancellationToken | A cancellation token. |
Returns | Description |
ProviderResult<T> | The resolved completion item or a thenable that resolves to of such. It is OK to return the given
|

. The lifecycle of a CustomDocument
is
managed by the editor. When no more references remain to a CustomDocument
, it is disposed of.
Properties
uri: Uri
The associated uri for this document.
Methods

This is invoked by the editor when there are no more references to a given CustomDocument
(for example when
all editors associated with the document have been closed.)
Parameter | Description |
---|---|
Returns | Description |
void |
CustomDocumentBackup
A backup for an CustomDocument.
Properties
Unique identifier for the backup.
This id is passed back to your extension in openCustomDocument
when opening a custom editor from a backup.
Methods
Delete the current backup.
This is called by the editor when it is clear the current backup is no longer needed, such as when a new backup is made or when the file is saved.
Parameter | Description |
---|---|
Returns | Description |
void |
CustomDocumentBackupContext
Additional information used to implement CustomDocumentBackup.
Properties
destination: Uri
Suggested file location to write the new backup.
Note that your extension is free to ignore this and use its own strategy for backup.
If the editor is for a resource from the current workspace, destination
will point to a file inside
ExtensionContext.storagePath
. The parent folder of destination
may not exist, so make sure to created it
before writing the backup to this location.
CustomDocumentContentChangeEvent<T>
Event triggered by extensions to signal to the editor that the content of a CustomDocument has changed.
Properties
The document that the change is for.
CustomDocumentEditEvent<T>
Event triggered by extensions to signal to the editor that an edit has occurred on an CustomDocument.
Properties
The document that the edit is for.
Display name describing the edit.
This will be shown to users in the UI for undo/redo operations.
Methods
Redo the edit operation.
This is invoked by the editor when the user redoes this edit. To implement redo
, your
extension should restore the document and editor to the state they were in just after this
edit was added to the editor's internal edit stack by onDidChangeCustomDocument
.
Parameter | Description |
---|---|
Returns | Description |
void | Thenable<void> |
Undo the edit operation.
This is invoked by the editor when the user undoes this edit. To implement undo
, your
extension should restore the document and editor to the state they were in just before this
edit was added to the editor's internal edit stack by onDidChangeCustomDocument
.
Parameter | Description |
---|---|
Returns | Description |
void | Thenable<void> |
CustomDocumentOpenContext
Additional information about the opening custom document.
Properties
The id of the backup to restore the document from or undefined
if there is no backup.
If this is provided, your extension should restore the editor from the backup instead of reading the file from the user's workspace.
untitledDocumentData: Uint8Array
If the URI is an untitled file, this will be populated with the byte data of that file
If this is provided, your extension should utilize this byte data rather than executing fs APIs on the URI passed in
CustomEditorProvider<T>
Provider for editable custom editors that use a custom document model.
Custom editors use CustomDocument as their document model instead of a TextDocument. This gives extensions full control over actions such as edit, save, and backup.
You should use this type of custom editor when dealing with binary files or more complex scenarios. For simple text based documents, use CustomTextEditorProvider instead.
Events
onDidChangeCustomDocument: Event<CustomDocumentEditEvent<T>> | Event<CustomDocumentContentChangeEvent<T>>
Signal that an edit has occurred inside a custom editor.
This event must be fired by your extension whenever an edit happens in a custom editor. An edit can be anything from changing some text, to cropping an image, to reordering a list. Your extension is free to define what an edit is and what data is stored on each edit.
Firing onDidChange
causes the editors to be marked as being dirty. This is cleared when the user either
saves or reverts the file.
Editors that support undo/redo must fire a CustomDocumentEditEvent
whenever an edit happens. This allows
users to undo and redo the edit using the editor's standard keyboard shortcuts. The editor will also mark
the editor as no longer being dirty if the user undoes all edits to the last saved state.
Editors that support editing but cannot use the editor's standard undo/redo mechanism must fire a CustomDocumentContentChangeEvent
.
The only way for a user to clear the dirty state of an editor that does not support undo/redo is to either
save
or revert
the file.
An editor should only ever fire CustomDocumentEditEvent
events, or only ever fire CustomDocumentContentChangeEvent
events.
Methods
backupCustomDocument(document: T, context: CustomDocumentBackupContext, cancellation: CancellationToken): Thenable<CustomDocumentBackup>
Back up a dirty custom document.
Backups are used for hot exit and to prevent data loss. Your backup
method should persist the resource in
its current state, i.e. with the edits applied. Most commonly this means saving the resource to disk in
the ExtensionContext.storagePath
. When the editor reloads and your custom editor is opened for a resource,
your extension should first check to see if any backups exist for the resource. If there is a backup, your
extension should load the file contents from there instead of from the resource in the workspace.
backup
is triggered approximately one second after the user stops editing the document. If the user
rapidly edits the document, backup
will not be invoked until the editing stops.
backup
is not invoked when auto save
is enabled (since auto save already persists the resource).
Parameter | Description |
---|---|
document: T | Document to backup. |
context: CustomDocumentBackupContext | Information that can be used to backup the document. |
cancellation: CancellationToken | Token that signals the current backup since a new backup is coming in. It is up to your extension to decided how to respond to cancellation. If for example your extension is backing up a large file in an operation that takes time to complete, your extension may decide to finish the ongoing backup rather than cancelling it to ensure that the editor has some valid backup. |
Returns | Description |
Thenable<CustomDocumentBackup> |
openCustomDocument(uri: Uri, openContext: CustomDocumentOpenContext, token: CancellationToken): T | Thenable<T>
Create a new document for a given resource.
openCustomDocument
is called when the first time an editor for a given resource is opened. The opened
document is then passed to resolveCustomEditor
so that the editor can be shown to the user.
Already opened CustomDocument
are re-used if the user opened additional editors. When all editors for a
given resource are closed, the CustomDocument
is disposed of. Opening an editor at this point will
trigger another call to openCustomDocument
.
Parameter | Description |
---|---|
uri: Uri | Uri of the document to open. |
openContext: CustomDocumentOpenContext | Additional information about the opening custom document. |
token: CancellationToken | A cancellation token that indicates the result is no longer needed. |

the event listeners on it that it is interested in. The provider can also hold onto the |
token: CancellationToken | A cancellation token that indicates the result is no longer needed. |
Returns | Description |
void | Thenable<void> | Optional thenable indicating that the custom editor has been resolved. |
revertCustomDocument(document: T, cancellation: CancellationToken): Thenable<void>
Revert a custom document to its last saved state.
This method is invoked by the editor when the user triggers File: Revert File
in a custom editor. (Note that
this is only used using the editor's File: Revert File
command and not on a git revert
of the file).
To implement revert
, the implementer must make sure all editor instances (webviews) for document
are displaying the document in the same state is saved in. This usually means reloading the file from the
workspace.
Parameter | Description |
---|---|
document: T | Document to revert. |
cancellation: CancellationToken | Token that signals the revert is no longer required. |
Returns | Description |
Thenable<void> | Thenable signaling that the change has completed. |
saveCustomDocument(document: T, cancellation: CancellationToken): Thenable<void>
Save a custom document.
This method is invoked by the editor when the user saves a custom editor. This can happen when the user
triggers save while the custom editor is active, by commands such as save all
, or by auto save if enabled.
To implement save
, the implementer must persist the custom editor. This usually means writing the
file data for the custom document to disk. After save
completes, any associated editor instances will
no longer be marked as dirty.
Parameter | Description |
---|---|
document: T | Document to save. |
cancellation: CancellationToken | Token that signals the save is no longer required (for example, if another save was triggered). |
Returns | Description |
Thenable<void> | Thenable signaling that saving has completed. |
saveCustomDocumentAs(document: T, destination: Uri, cancellation: CancellationToken): Thenable<void>
Save a custom document to a different location.
This method is invoked by the editor when the user triggers 'save as' on a custom editor. The implementer must
persist the custom editor to destination
.
When the user accepts save as, the current editor is be replaced by an non-dirty editor for the newly saved file.
Parameter | Description |
---|---|
document: T | Document to save. |
destination: Uri | Location to save to. |
cancellation: CancellationToken | Token that signals the save is no longer required. |
Returns | Description |
Thenable<void> | Thenable signaling that saving has completed. |
CustomExecution
Class used to execute an extension callback as a task.
Constructors
new CustomExecution(callback: (resolvedDefinition: TaskDefinition) => Thenable<Pseudoterminal>): CustomExecution
Constructs a CustomExecution task object. The callback will be executed when the task is run, at which point the extension should return the Pseudoterminal it will "run in". The task should wait to do further execution until Pseudoterminal.open is called. Task cancellation should be handled using Pseudoterminal.close. When the task is complete fire Pseudoterminal.onDidClose.
Parameter | Description |
---|---|
callback: (resolvedDefinition: TaskDefinition) => Thenable<Pseudoterminal> | The callback that will be called when the task is started by a user. Any ${} style variables that
were in the task definition will be resolved and passed into the callback as |
Returns | Description |
CustomExecution |
CustomReadonlyEditorProvider<T>
Provider for readonly custom editors that use a custom document model.
Custom editors use CustomDocument as their document model instead of a TextDocument.
You should use this type of custom editor when dealing with binary files or more complex scenarios. For simple text based documents, use CustomTextEditorProvider instead.
Methods
openCustomDocument(uri: Uri, openContext: CustomDocumentOpenContext, token: CancellationToken): T | Thenable<T>
Create a new document for a given resource.
openCustomDocument
is called when the first time an editor for a given resource is opened. The opened
document is then passed to resolveCustomEditor
so that the editor can be shown to the user.
Already opened CustomDocument
are re-used if the user opened additional editors. When all editors for a
given resource are closed, the CustomDocument
is disposed of. Opening an editor at this point will
trigger another call to openCustomDocument
.
Parameter | Description |
---|---|
uri: Uri | Uri of the document to open. |
openContext: CustomDocumentOpenContext | Additional information about the opening custom document. |
token: CancellationToken | A cancellation token that indicates the result is no longer needed. |

token: CancellationToken | A cancellation token that indicates the result is no longer needed. |
Returns | Description |
void | Thenable<void> | Optional thenable indicating that the custom editor has been resolved. |
CustomTextEditorProvider
Provider for text based custom editors.
Text based custom editors use a TextDocument as their data model. This considerably simplifies
implementing a custom editor as it allows the editor to handle many common operations such as
undo and backup. The provider is responsible for synchronizing text changes between the webview and the TextDocument
.
Methods
resolveCustomTextEditor(document: TextDocument, webviewPanel: WebviewPanel, token: CancellationToken): void | Thenable<void>

DocumentLinkProvider<T>
The document link provider defines the contract between extensions and feature of showing links in the editor.
Methods
provideDocumentLinks(document: TextDocument, token: CancellationToken): ProviderResult<T[]>
Provide links for the given document. Note that the editor ships with a default provider that detects
http(s)
and file
links.
Parameter | Description |
---|---|
document: TextDocument | The document in which the command was invoked. |
token: CancellationToken | A cancellation token. |
Returns | Description |
ProviderResult<T[]> | An array of document links or a thenable that resolves to such. The lack of a result
can be signaled by returning |
resolveDocumentLink(link: T, token: CancellationToken): ProviderResult<T>
Given a link fill in its target. This method is called when an incomplete link is selected in the UI. Providers can implement this method and return incomplete links (without target) from the provideDocumentLinks method which often helps to improve performance.
Parameter | Description |
---|---|
link: T | The link that is to be resolved. |
token: CancellationToken | A cancellation token. |
Returns | Description |
ProviderResult<T> |

DocumentSemanticTokensProvider
The document semantic tokens provider interface defines the contract between extensions and semantic tokens.
Events
onDidChangeSemanticTokens?: Event<void>
An optional event to signal that the semantic tokens from this provider have changed.
Methods
provideDocumentSemanticTokens(document: TextDocument, token: CancellationToken): ProviderResult<SemanticTokens>
Tokens in a file are represented as an array of integers. The position of each token is expressed relative to the token before it, because most tokens remain stable relative to each other when edits are made in a file.
In short, each token takes 5 integers to represent, so a specific token i
in the file consists of the following array indices:
- at index
5*i
-deltaLine
: token line number, relative to the previous token - at index
5*i+1
-deltaStart
: token start character, relative to the previous token (relative to 0 or the previous token's start if they are on the same line) - at index
5*i+2
-length
: the length of the token. A token cannot be multiline. - at index
5*i+3
-tokenType
: will be looked up inSemanticTokensLegend.tokenTypes
. We currently ask thattokenType
< 65536. - at index
5*i+4
-tokenModifiers
: each set bit will be looked up inSemanticTokensLegend.tokenModifiers
How to encode tokens
Here is an example for encoding a file with 3 tokens in a uint32 array:
{ line: 2, startChar: 5, length: 3, tokenType: "property", tokenModifiers: ["private", "static"] },
{ line: 2, startChar: 10, length: 4, tokenType: "type", tokenModifiers: [] },
{ line: 5, startChar: 2, length: 7, tokenType: "class", tokenModifiers: [] }
- First of all, a legend must be devised. This legend must be provided up-front and capture all possible token types. For this example, we will choose the following legend which must be passed in when registering the provider:
tokenTypes: ['property', 'type', 'class'],
tokenModifiers: ['private', 'static']
- The first transformation step is to encode
tokenType
andtokenModifiers
as integers using the legend. Token types are looked up by index, so atokenType
value of1
meanstokenTypes[1]
. Multiple token modifiers can be set by using bit flags, so atokenModifier
value of3
is first viewed as binary0b00000011
, which means[tokenModifiers[0], tokenModifiers[1]]
because bits 0 and 1 are set. Using this legend, the tokens now are:
{ line: 2, startChar: 5, length: 3, tokenType: 0, tokenModifiers: 3 },
{ line: 2, startChar: 10, length: 4, tokenType: 1, tokenModifiers: 0 },
{ line: 5, startChar: 2, length: 7, tokenType: 2, tokenModifiers: 0 }
- The next step is to represent each token relative to the previous token in the file. In this case, the second token
is on the same line as the first token, so the
startChar
of the second token is made relative to thestartChar
of the first token, so it will be10 - 5
. The third token is on a different line than the second token, so thestartChar
of the third token will not be altered:
{ deltaLine: 2, deltaStartChar: 5, length: 3, tokenType: 0, tokenModifiers: 3 },
{ deltaLine: 0, deltaStartChar: 5, length: 4, tokenType: 1, tokenModifiers: 0 },
{ deltaLine: 3, deltaStartChar: 2, length: 7, tokenType: 2, tokenModifiers: 0 }
- Finally, the last step is to inline each of the 5 fields for a token in a single array, which is a memory friendly representation:
// 1st token, 2nd token, 3rd token
[ 2,5,3,0,3, 0,5,4,1,0, 3,2,7,2,0 ]
See also SemanticTokensBuilder for a helper to encode tokens as integers. NOTE: When doing edits, it is possible that multiple edits occur until the editor decides to invoke the semantic tokens provider. NOTE: If the provider cannot temporarily compute semantic tokens, it can indicate this by throwing an error with the message 'Busy'.
Parameter | Description |
---|---|
document: TextDocument | |
token: CancellationToken | |
Returns | Description |
ProviderResult<SemanticTokens> |
provideDocumentSemanticTokensEdits(document: TextDocument, previousResultId: string, token: CancellationToken): ProviderResult<SemanticTokens | SemanticTokensEdits>
Instead of always returning all the tokens in a file, it is possible for a DocumentSemanticTokensProvider
to implement
this method (provideDocumentSemanticTokensEdits
) and then return incremental updates to the previously provided semantic tokens.
How tokens change when the document changes
Suppose that provideDocumentSemanticTokens
has previously returned the following semantic tokens:
// 1st token, 2nd token, 3rd token
[ 2,5,3,0,3, 0,5,4,1,0, 3,2,7,2,0 ]
Also suppose that after some edits, the new semantic tokens in a file are:
// 1st token, 2nd token, 3rd token
[ 3,5,3,0,3, 0,5,4,1,0, 3,2,7,2,0 ]
It is possible to express these new tokens in terms of an edit applied to the previous tokens:
[ 2,5,3,0,3, 0,5,4,1,0, 3,2,7,2,0 ] // old tokens
[ 3,5,3,0,3, 0,5,4,1,0, 3,2,7,2,0 ] // new tokens
edit: { start: 0, deleteCount: 1, data: [3] } // replace integer at offset 0 with 3
NOTE: If the provider cannot compute SemanticTokensEdits
, it can "give up" and return all the tokens in the document again.
NOTE: All edits in SemanticTokensEdits
contain indices in the old integers array, so they all refer to the previous result state.

document: TextDocument | |
previousResultId: string | |
token: CancellationToken | |
Returns | Description |
ProviderResult<SemanticTokens | SemanticTokensEdits> |

FileSystemProvider
The filesystem provider defines what the editor needs to read, write, discover, and to manage files and folders. It allows extensions to serve files from remote places, like ftp-servers, and to seamlessly integrate those into the editor.
- Note 1: The filesystem provider API works with uris and assumes hierarchical
paths, e.g.
foo:/my/path
is a child offoo:/my/
and a parent offoo:/my/path/deeper
. - Note 2: There is an activation event
onFileSystem:<scheme>
that fires when a file or folder is being accessed. - Note 3: The word 'file' is often used to denote all kinds of files, e.g. folders, symbolic links, and regular files.
Events
onDidChangeFile: Event<FileChangeEvent[]>
An event to signal that a resource has been created, changed, or deleted. This event should fire for resources that are being watched by clients of this provider.
Note: It is important that the metadata of the file that changed provides an
updated mtime
that advanced from the previous value in the stat and a
correct size
value. Otherwise there may be optimizations in place that will not show
the change in an editor for example.
Methods
copy(source: Uri, destination: Uri, options: {overwrite: boolean}): void | Thenable<void>
Copy files or folders. Implementing this function is optional but it will speedup the copy operation.
- throws - FileNotFound when

.
- throws - FileNotFound when
uri
doesn't exist.
watch(uri: Uri, options: {excludes: readonly string[], recursive: boolean}): Disposable
Subscribes to file change events in the file or folder denoted by uri
. For folders,
the option recursive
indicates whether subfolders, sub-subfolders, etc. should
be watched for file changes as well. With recursive: false
, only changes to the
files that are direct children of the folder should trigger an event.
The excludes
array is used to indicate paths that should be excluded from file
watching. It is typically derived from the files.watcherExclude
setting that
is configurable by the user. Each entry can be be:
- the absolute path to exclude
- a relative path to exclude (for example
build/output
) - a simple glob pattern (for example
**/build
,output/**
)
It is the file system provider's job to call onDidChangeFile for every change given these rules. No event should be emitted for files that match any of the provided excludes.

GlobPattern
A file glob pattern to match file paths against. This can either be a glob pattern string
(like **/*.{ts,js}
or *.{ts,js}
) or a relative pattern.
Glob patterns can have the following syntax:
*
to match zero or more characters in a path segment?
to match on one character in a path segment**
to match any number of path segments, including none{}
to group conditions (e.g.**/*.{ts,js}
matches all TypeScript and JavaScript files)[]
to declare a range of characters to match in a path segment (e.g.,example.[0-9]
to match onexample.0
,example.1
, …)[!...]
to negate a range of characters to match in a path segment (e.g.,example.[!0-9]
to match onexample.a
,example.b
, but notexample.0
)
Note: a backslash (``) is not valid within a glob pattern. If you have an existing file path to match against, consider to use the relative pattern support that takes care of converting any backslash into slash. Otherwise, make sure to convert any backslash to slash when creating the glob pattern.

sendRequest(messages: LanguageModelChatMessage[], options?: LanguageModelChatRequestOptions, token?: CancellationToken): Thenable<LanguageModelChatResponse>
Make a chat request using a language model.
Note that language model use may be subject to access restrictions and user consent. Calling this function for the first time (for an extension) will show a consent dialog to the user and because of that this function must only be called in response to a user action! Extensions can use LanguageModelAccessInformation.canSendRequest to check if they have the necessary permissions to make a request.
This function will return a rejected promise if making a request to the language model is not possible. Reasons for this can be:
- user consent not given, see
NoPermissions
- model does not exist anymore, see
NotFound
- quota limits exceeded, see
Blocked
- other issues in which case extension must check [LanguageModelError.cause
LanguageModelError.cause
](#LanguageModelError.causeLanguageModelError.cause
)
An extension can make use of language model tool calling by passing a set of tools to LanguageModelChatRequestOptions.tools. The language model will return a LanguageModelToolCallPart and the extension can invoke the tool and make another request with the result.
Parameter | Description |
---|---|
messages: LanguageModelChatMessage[] | An array of message instances. |
options?: LanguageModelChatRequestOptions | Options that control the request. |
token?: CancellationToken | A cancellation token which controls the request. See CancellationTokenSource for how to create one. |

toolMode?: LanguageModelChatToolMode
The tool-selecting mode to use. LanguageModelChatToolMode.Auto by default.
tools?: LanguageModelChatTool[]
An optional list of tools that are available to the language model. These could be registered tools available via lm.tools, or private tools that are just implemented within the calling extension.
If the LLM requests to call one of these tools, it will return a LanguageModelToolCallPart in LanguageModelChatResponse.stream. It's the caller's responsibility to invoke the tool. If it's a tool registered in lm.tools, that means calling lm.invokeTool.
Then, the tool result can be provided to the LLM by creating an Assistant-type LanguageModelChatMessage with a LanguageModelToolCallPart, followed by a User-type message with a LanguageModelToolResultPart.
LanguageModelChatResponse
Represents a language model response.
See also LanguageModelAccess.chatRequest
Properties
stream: AsyncIterable<unknown>
An async iterable that is a stream of text and tool-call parts forming the overall response. A
LanguageModelTextPart is part of the assistant's response to be shown to the user. A
LanguageModelToolCallPart is a request from the language model to call a tool. The latter will
only be returned if tools were passed in the request via LanguageModelChatRequestOptions.tools. The
unknown
-type is used as a placeholder for future parts, like image data parts.
Note that this stream will error when during data receiving an error occurs. Consumers of the stream should handle the errors accordingly.
To cancel the stream, the consumer can cancel the token that was used to make the request or break from the for-loop.
Example
try {
// consume stream
for await (const chunk of response.stream) {
if (chunk instanceof LanguageModelTextPart) {
console.log('TEXT', chunk);
} else if (chunk instanceof LanguageModelToolCallPart) {
console.log('TOOL CALL', chunk);
}
}
} catch (e) {
// stream ended with an error
console.error(e);
}
This is equivalent to filtering everything except for text parts from a LanguageModelChatResponse.stream.

NotebookController
A notebook controller represents an entity that can execute notebook cells. This is often referred to as a kernel.
There can be multiple controllers and the editor will let users choose which controller to use for a certain notebook. The notebookType-property defines for what kind of notebooks a controller is for and the updateNotebookAffinity-function allows controllers to set a preference for specific notebook documents. When a controller has been selected its onDidChangeSelectedNotebooks-event fires.
When a cell is being run the editor will invoke the executeHandler and a controller is expected to create and finalize a notebook cell execution. However, controllers are also free to create executions by themselves.
Events
onDidChangeSelectedNotebooks: Event<{notebook: NotebookDocument, selected: boolean}>
An event that fires whenever a controller has been selected or un-selected for a notebook document.
There can be multiple controllers for a notebook and in that case a controllers needs to be selected. This is a user gesture and happens either explicitly or implicitly when interacting with a notebook for which a controller was suggested. When possible, the editor suggests a controller that is most likely to be selected.
Note that controller selection is persisted (by the controllers id) and restored as soon as a controller is re-created or as a notebook is opened.
Properties
The human-readable description which is rendered less prominent.
The human-readable detail which is rendered less prominent.
executeHandler: (cells: NotebookCell[], notebook: NotebookDocument, controller: NotebookController) => void | Thenable<void>
The execute handler is invoked when the run gestures in the UI are selected, e.g Run Cell, Run All, Run Selection etc. The execute handler is responsible for creating and managing execution-objects.
Parameter | Description |
---|---|
cells: NotebookCell[] | |
notebook: NotebookDocument | |
controller: NotebookController | |
Returns | Description |
void | Thenable<void> |
The identifier of this notebook controller.
Note that controllers are remembered by their identifier and that extensions should use stable identifiers across sessions.
interruptHandler?: (notebook: NotebookDocument) => void | Thenable<void>
Optional interrupt handler.
By default cell execution is canceled via tokens. Cancellation
tokens require that a controller can keep track of its execution so that it can cancel a specific execution at a later
point. Not all scenarios allow for that, eg. REPL-style controllers often work by interrupting whatever is currently
running. For those cases the interrupt handler exists - it can be thought of as the equivalent of SIGINT
or Control+C
in terminals.
Note that supporting cancellation tokens is preferred and that interrupt handlers should only be used when tokens cannot be supported.
Parameter | Description |
---|---|
notebook: NotebookDocument | |
Returns | Description |
void | Thenable<void> |
The human-readable label of this notebook controller.
The notebook type this controller is for.

myController.supportedLanguages = ['javascript', 'typescript'];
// support all languages
myController.supportedLanguages = undefined; // falsy
myController.supportedLanguages = []; // falsy
supportsExecutionOrder?: boolean
Whether this controller supports execution order so that the editor can render placeholders for them.
Methods
createNotebookCellExecution(cell: NotebookCell): NotebookCellExecution
Create a cell execution task.
Note that there can only be one execution per cell at a time and that an error is thrown if a cell execution is created while another is still active.
This should be used in response to the execution handler being called or when cell execution has been started else, e.g when a cell was already executing or when cell execution was triggered from another source.
Parameter | Description |
---|---|

Pseudoterminal
Defines the interface of a terminal pty, enabling extensions to control a terminal.
Events
onDidChangeName?: Event<string>
An event that when fired allows changing the name of the terminal.
Events fired before Pseudoterminal.open is called will be be ignored.
Example: Change the terminal name to "My new terminal".
const writeEmitter = new vscode.EventEmitter<string>();
const changeNameEmitter = new vscode.EventEmitter<string>();
const pty: vscode.Pseudoterminal = {
onDidWrite: writeEmitter.event,
onDidChangeName: changeNameEmitter.event,
open: () => changeNameEmitter.fire('My new terminal'),
close: () => {}
};
vscode.window.createTerminal({ name: 'My terminal', pty });
onDidClose?: Event<number | void>
An event that when fired will signal that the pty is closed and dispose of the terminal.
Events fired before Pseudoterminal.open is called will be be ignored.
A number can be used to provide an exit code for the terminal. Exit codes must be
positive and a non-zero exit codes signals failure which shows a notification for a
regular terminal and allows dependent tasks to proceed when used with the
CustomExecution
API.
Example: Exit the terminal when "y" is pressed, otherwise show a notification.
const writeEmitter = new vscode.EventEmitter<string>();
const closeEmitter = new vscode.EventEmitter<void>();
const pty: vscode.Pseudoterminal = {
onDidWrite: writeEmitter.event,
onDidClose: closeEmitter.event,
open: () => writeEmitter.fire('Press y to exit successfully'),
close: () => {},
handleInput: data => {
if (data !== 'y') {
vscode.window.showInformationMessage('Something went wrong');
}
closeEmitter.fire();
}
};
const terminal = vscode.window.createTerminal({ name: 'Exit example', pty });
terminal.show(true);
onDidOverrideDimensions?: Event<TerminalDimensions>
An event that when fired allows overriding the dimensions of the
terminal. Note that when set, the overridden dimensions will only take effect when they
are lower than the actual dimensions of the terminal (ie. there will never be a scroll
bar). Set to undefined
for the terminal to go back to the regular dimensions (fit to
the size of the panel).
Events fired before Pseudoterminal.open is called will be be ignored.
Example: Override the dimensions of a terminal to 20 columns and 10 rows
const dimensionsEmitter = new vscode.EventEmitter<vscode.TerminalDimensions>();
const pty: vscode.Pseudoterminal = {
onDidWrite: writeEmitter.event,
onDidOverrideDimensions: dimensionsEmitter.event,
open: () => {
dimensionsEmitter.fire({
columns: 20,
rows: 10
});
},
close: () => {}
};
vscode.window.createTerminal({ name: 'My terminal', pty });
onDidWrite: Event<string>
An event that when fired will write data to the terminal. Unlike Terminal.sendText which sends text to the underlying child pseudo-device (the child), this will write the text to parent pseudo-device (the terminal itself).
Note writing \n
will just move the cursor down 1 row, you need to write \r
as well
to move the cursor to the left-most cell.
Events fired before Pseudoterminal.open is called will be be ignored.
Example: Write red text to the terminal
const writeEmitter = new vscode.EventEmitter<string>();
const pty: vscode.Pseudoterminal = {
onDidWrite: writeEmitter.event,
open: () => writeEmitter.fire('\x1b[31mHello world\x1b[0m'),
close: () => {}
};
vscode.window.createTerminal({ name: 'My terminal', pty });
Example: Move the cursor to the 10th row and 20th column and write an asterisk
writeEmitter.fire('\x1b[10;20H*');
Methods

data: string | The incoming data. Example: Echo input in the terminal. The sequence for enter (
|
Returns | Description |
void |
open(initialDimensions: TerminalDimensions): void
Implement to handle when the pty is open and ready to start firing events.
Parameter | Description |
---|---|
initialDimensions: TerminalDimensions | The dimensions of the terminal, this will be undefined if the terminal panel has not been opened before this is called. |
Returns | Description |
void |
setDimensions(dimensions: TerminalDimensions): void
Implement to handle when the number of rows and columns that fit into the terminal panel
changes, for example when font size changes or when the panel is resized. The initial
state of a terminal's dimensions should be treated as undefined
until this is triggered
as the size of a terminal isn't known until it shows up in the user interface.
When dimensions are overridden by
onDidOverrideDimensions, setDimensions
will
continue to be called with the regular panel dimensions, allowing the extension continue
to react dimension changes.
Parameter | Description |
---|---|
dimensions: TerminalDimensions | The new dimensions. |
Returns | Description |
void |
QuickDiffProvider
A quick diff provider provides a uri to the original state of a modified resource. The editor will use this information to render ad'hoc diffs within the text.

QuickInput
A light-weight user input UI that is initially not visible. After configuring it through its properties the extension can make it visible by calling QuickInput.show.
There are several reasons why this UI might have to be hidden and the extension will be notified through QuickInput.onDidHide. (Examples include: an explicit call to QuickInput.hide, the user pressing Esc, some other input UI opening, etc.)
A user pressing Enter or some other gesture implying acceptance of the current state does not automatically hide this UI component. It is up to the extension to decide whether to accept the user's input and if the UI should indeed be hidden through a call to QuickInput.hide.
When the extension no longer needs this input UI, it should QuickInput.dispose it to allow for freeing up any resources associated with it.
Events
onDidHide: Event<void>
An event signaling when this input UI is hidden.
There are several reasons why this UI might have to be hidden and the extension will be notified through QuickInput.onDidHide. (Examples include: an explicit call to QuickInput.hide, the user pressing Esc, some other input UI opening, etc.)
Properties
If the UI should show a progress indicator. Defaults to false.
Change this to true, e.g., while loading more data or validating user input.
If the UI should allow for user input. Defaults to true.
Change this to false, e.g., while validating user input or loading data for the next step in user input.
If the UI should stay open even when loosing UI focus. Defaults to false. This setting is ignored on iPad and is always false.
An optional current step count.
An optional title.
An optional total step count.
Methods
Dispose of this input UI and any associated resources. If it is still visible, it is first hidden. After this call the input UI is no longer functional and no additional methods or properties on it should be accessed. Instead a new input UI should be created.
Parameter | Description |
---|---|
Returns | Description |
void |
Hides this input UI. This will also fire an QuickInput.onDidHide event.

TerminalShellExecution
A command that was executed in a terminal.
Properties
commandLine: TerminalShellExecutionCommandLine
The command line that was executed. The confidence of this value depends on the specific shell's shell integration implementation. This value may become more accurate after window.onDidEndTerminalShellExecution is fired.
Example
// Log the details of the command line on start and end
window.onDidStartTerminalShellExecution(event => {
const commandLine = event.execution.commandLine;
console.log(`Command started\n${summarizeCommandLine(commandLine)}`);
});
window.onDidEndTerminalShellExecution(event => {
const commandLine = event.execution.commandLine;
console.log(`Command ended\n${summarizeCommandLine(commandLine)}`);
});
function summarizeCommandLine(commandLine: TerminalShellExecutionCommandLine) {
return [
` Command line: ${command.commandLine.value}`,
` Confidence: ${command.commandLine.confidence}`,
` Trusted: ${command.commandLine.isTrusted}
].join('\n');
}
cwd: Uri
The working directory that was reported by the shell when this command executed. This Uri may represent a file on another machine (eg. ssh into another machine). This requires the shell integration to support working directory reporting.
Methods
Creates a stream of raw data (including escape sequences) that is written to the
terminal. This will only include data that was written after read
was called for
the first time, ie. you must call read
immediately after the command is executed via
TerminalShellIntegration.executeCommand or
window.onDidStartTerminalShellExecution to not miss any data.
Example
// Log all data written to the terminal for a command
const command = term.shellIntegration.executeCommand({ commandLine: 'echo "Hello world"' });
const stream = command.read();
for await (const data of stream) {
console.log(data);
}
Parameter | Description |
---|---|
Returns | Description |
AsyncIterable<string> |
TerminalShellExecutionCommandLine
A command line that was executed in a terminal.
Properties
confidence: TerminalShellExecutionCommandLineConfidence
The confidence of the command line value which is determined by how the value was obtained. This depends upon the implementation of the shell integration script.
Whether the command line value came from a trusted source and is therefore safe to execute without user additional confirmation, such as a notification that asks "Do you want to execute (command)?". This verification is likely only needed if you are going to execute the command again.
This is true
only when the command line was reported explicitly by the shell
integration script (ie. high confidence)
and it used a nonce for verification.
The full command line that was executed, including both the command and its arguments.
TerminalShellExecutionCommandLineConfidence
The confidence of a TerminalShellExecutionCommandLine value.
Enumeration Members
The command line value confidence is low. This means that the value was read from the terminal buffer using markers reported by the shell integration script. Additionally one of the following conditions will be met:
- The command started on the very left-most column which is unusual, or
- The command is multi-line which is more difficult to accurately detect due to line continuation characters and right prompts.
- Command line markers were not reported by the shell integration script.
The command line value confidence is medium. This means that the value was read from the terminal buffer using markers reported by the shell integration script. The command is single-line and does not start on the very left-most column (which is unusual).
The command line value confidence is high. This means that the value was explicitly sent from the shell integration script or the command was executed via the TerminalShellIntegration.executeCommand API.
TerminalShellExecutionEndEvent
An event signalling that an execution has ended in a terminal.
Properties
execution: TerminalShellExecution
The terminal shell execution that has ended.
The exit code reported by the shell.
Note that undefined
means the shell either did not report an exit code (ie. the shell
integration script is misbehaving) or the shell reported a command started before the command
finished (eg. a sub-shell was opened). Generally this should not happen, depending on the use
case, it may be best to treat this as a failure.
Example
const execution = shellIntegration.executeCommand({
command: 'echo',
args: ['Hello world']
});
window.onDidEndTerminalShellExecution(event => {
if (event.execution === execution) {
if (event.exitCode === undefined) {
console.log('Command finished but exit code is unknown');

Example
// Execute a command in a terminal immediately after being created
const myTerm = window.createTerminal();

if (terminal === myTerm) {
const execution = shellIntegration.executeCommand('echo "Hello world"');
window.onDidEndTerminalShellExecution(event => {
if (event.execution === execution) {
console.log(`Command exited with code ${event.exitCode}`);
}
});
}
}));
// Fallback to sendText if there is no shell integration within 3 seconds of launching
setTimeout(() => {
if (!myTerm.shellIntegration) {
myTerm.sendText('echo "Hello world"');
// Without shell integration, we can't know when the command has finished or what the
// exit code was.
}
}, 3000);
Example
// Send command to terminal that has been alive for a while
const commandLine = 'echo "Hello world"';
if (term.shellIntegration) {
const execution = shellIntegration.executeCommand({ commandLine });

const myTerm = window.createTerminal();
window.onDidChangeTerminalShellIntegration(async ({ terminal, shellIntegration }) => {
if (terminal === myTerm) {
const command = shellIntegration.executeCommand({

Represents the state of a Terminal.
Properties
Whether the Terminal has been interacted with. Interaction means that the terminal has sent data to the process which depending on the terminal's mode. By default input is sent when a key is pressed or when a command or extension sends text, but based on the terminal's mode it can also happen on:
- a pointer click event
- a pointer scroll event
- a pointer move event
- terminal focus in/out
For more information on events that can send data see "DEC Private Mode Set (DECSET)" on https://invisible-island.net/xterm/ctlseqs/ctlseqs.html
TestController
Entry point to discover and execute tests. It contains TestController.items which are used to populate the editor UI, and is associated with run profiles to allow for tests to be executed.
Properties
The id of the controller passed in tests.createTestController. This must be globally unique.
items: TestItemCollection
A collection of "top-level" TestItem instances, which can in turn have their own children to form the "test tree."
The extension controls when to add tests. For example, extensions should add tests for a file when workspace.onDidOpenTextDocument fires in order for decorations for tests within a file to be visible.
However, the editor may sometimes explicitly request children using the resolveHandler See the documentation on that method for more details.
Human-readable label for the test controller.
refreshHandler: (token: CancellationToken) => void | Thenable<void>
If this method is present, a refresh button will be present in the UI, and this method will be invoked when it's clicked. When called, the extension should scan the workspace for any new, changed, or removed tests.
It's recommended that extensions try to update tests in realtime, using a FileSystemWatcher for example, and use this method as a fallback.
Parameter | Description |
---|---|
token: CancellationToken | |
Returns | Description |
void | Thenable<void> | A thenable that resolves when tests have been refreshed. |
resolveHandler?: (item: TestItem) => void | Thenable<void>
A function provided by the extension that the editor may call to request
children of a test item, if the TestItem.canResolveChildren is
true
. When called, the item should discover children and call
TestController.createTestItem as children are discovered.
Generally the extension manages the lifecycle of test items, but under certain conditions the editor may request the children of a specific item to be loaded. For example, if the user requests to re-run tests after reloading the editor, the editor may need to call this method to resolve the previously-run tests.
The item in the explorer will automatically be marked as "busy" until the function returns or the returned thenable resolves.
Methods
createRunProfile(label: string, kind: TestRunProfileKind, runHandler: (request: TestRunRequest, token: CancellationToken) => void | Thenable<void>, isDefault?: boolean, tag?: TestTag, supportsContinuousRun?: boolean): TestRunProfile

createTestRun(request: TestRunRequest, name?: string, persist?: boolean): TestRun
Creates a TestRun. This should be called by the TestRunProfile when a request is made to execute tests, and may also be called if a test run is detected externally. Once created, tests that are included in the request will be moved into the queued state.
All runs created using the same request
instance will be grouped
together. This is useful if, for example, a single suite of tests is
run on multiple platforms.
Parameter | Description |
---|---|
request: TestRunRequest | Test run request. Only tests inside the |
name?: string | The human-readable name of the run. This can be used to disambiguate multiple sets of results in a test run. It is useful if tests are run across multiple platforms, for example. |
persist?: boolean | Whether the results created by the run should be persisted in the editor. This may be false if the results are coming from a file already saved externally, such as a coverage information file. |
Returns | Description |
TestRun | An instance of the TestRun. It will be considered "running" from the moment this method is invoked until TestRun.end is called. |
Unregisters the test controller, disposing of its associated tests and unpersisted results.

Returns | Description |
void |
invalidateTestResults(items?: TestItem | readonly TestItem[]): void
Marks an item's results as being outdated. This is commonly called when code or configuration changes and previous results should no longer be considered relevant. The same logic used to mark results as outdated may be used to drive continuous test runs.
If an item is passed to this method, test results for the item and all of its children will be marked as outdated. If no item is passed, then all test owned by the TestController will be marked as outdated.
Any test runs started before the moment this method is called, including runs which may still be ongoing, will be marked as outdated and deprioritized in the editor's UI.

Controls whether this profile is the default action that will be taken when its kind is actioned. For example, if the user clicks the generic "run all" button, then the default profile for TestRunProfileKind.Run will be executed, although the user can configure this.
Changes the user makes in their default profiles will be reflected in this property after a onDidChangeDefault event.
kind: TestRunProfileKind
Configures what kind of execution this profile controls. If there are no profiles for a kind, it will not be available in the UI.
Label shown to the user in the UI.
Note that the label has some significance if the user requests that
tests be re-run in a certain way. For example, if tests were run
normally and the user requests to re-run them in debug mode, the editor
will attempt use a configuration with the same label of the Debug
kind. If there is no such configuration, the default will be used.
loadDetailedCoverage?: (testRun: TestRun, fileCoverage: FileCoverage, token: CancellationToken) => Thenable<FileCoverageDetail[]>
An extension-provided function that provides detailed statement and function-level coverage for a file. The editor will call this when more detail is needed for a file, such as when it's opened in an editor or expanded in the Test Coverage view.
The FileCoverage object passed to this function is the same instance emitted on TestRun.addCoverage calls associated with this profile.
Parameter | Description |
---|---|
testRun: TestRun | |
fileCoverage: FileCoverage | |
token: CancellationToken | |
Returns | Description |
Thenable<FileCoverageDetail[]> |
runHandler: (request: TestRunRequest, token: CancellationToken) => void | Thenable<void>
Handler called to start a test run. When invoked, the function should call TestController.createTestRun at least once, and all test runs associated with the request should be created before the function returns or the returned promise is resolved.
If supportsContinuousRun is set, then TestRunRequest.continuous
may be true
. In this case, the profile should observe changes to
source code and create new test runs by calling TestController.createTestRun,
until the cancellation is requested on the token
.
Parameter | Description |
---|---|
request: TestRunRequest | Request information for the test run. |
token: CancellationToken | |
Returns | Description |
void | Thenable<void> |
supportsContinuousRun: boolean
Whether this profile supports continuous running of requests. If so,
then TestRunRequest.continuous may be set to true
. Defaults
to false.

TestRunRequest
A TestRunRequest is a precursor to a TestRun, which in turn is created by passing a request to TestController.createTestRun. The TestRunRequest contains information about which tests should be run, which should not be run, and how they are run (via the profile).
In general, TestRunRequests are created by the editor and pass to
TestRunProfile.runHandler, however you can also create test
requests and runs outside of the runHandler
.

exclude: readonly TestItem[]
An array of tests the user has marked as excluded from the test included in this run; exclusions should apply after inclusions.
May be omitted if no exclusions were requested. Test controllers should not run excluded tests or any children of excluded tests.
include: readonly TestItem[]
A filter for specific tests to run. If given, the extension should run all of the included tests and all their children, excluding any tests that appear in TestRunRequest.exclude. If this property is undefined, then the extension should simply run all tests.
The process of running tests should resolve the children of any test items who have not yet been resolved.
Controls how test Test Results view is focused. If true, the editor will keep the maintain the user's focus. If false, the editor will prefer to move focus into the Test Results view, although this may be configured by users.
profile: TestRunProfile
The profile used for this request. This will always be defined for requests issued from the editor UI, though extensions may programmatically create requests not associated with any profile.

This could be well-defined, existing, mime types, and also mime types defined by the extension.
The recommended mime type of the tree (application/vnd.code.tree.<treeidlowercase>
) will be automatically added.
dropMimeTypes: readonly string[]
The mime types that the handleDrop
method of this DragAndDropController
supports.
This could be well-defined, existing, mime types, and also mime types defined by the extension.
To support drops from trees, you will need to add the mime type of that tree.
This includes drops from within the same tree.
The mime type of a tree is recommended to be of the format application/vnd.code.tree.<treeidlowercase>
.
Use the special files
mime type to support all types of dropped files files, regardless of the file's actual mime type.
To learn the mime type of a dragged item:
- Set up your
DragAndDropController
- Use the Developer: Set Log Level... command to set the level to "Debug"
- Open the developer tools and drag the item with unknown mime type over your tree. The mime types will be logged to the developer console
Note that mime types that cannot be sent to the extension will be omitted.
Methods
handleDrag(source: readonly T[], dataTransfer: DataTransfer, token: CancellationToken): void | Thenable<void>
When the user starts dragging items from this DragAndDropController
, handleDrag
will be called.
Extensions can use handleDrag
to add their DataTransferItem
items to the drag and drop.
When the items are dropped on another tree item in the same tree, your DataTransferItem
objects
will be preserved. Use the recommended mime type for the tree (application/vnd.code.tree.<treeidlowercase>
) to add
tree objects in a data transfer. See the documentation for DataTransferItem
for how best to take advantage of this.
To add a data transfer item that can be dragged into the editor, use the application specific mime type "text/uri-list".
The data for "text/uri-list" should be a string with toString()
ed Uris separated by \r\n
. To specify a cursor position in the file,
set the Uri's fragment to L3,5
, where 3 is the line number and 5 is the column number.
Parameter | Description |
---|---|
source: readonly T[] | The source items for the drag and drop operation. |
dataTransfer: DataTransfer | The data transfer associated with this drag. |
token: CancellationToken | A cancellation token indicating that drag has been cancelled. |
Returns | Description |
void | Thenable<void> |
handleDrop(target: T, dataTransfer: DataTransfer, token: CancellationToken): void | Thenable<void>
Called when a drag and drop action results in a drop on the tree that this DragAndDropController
belongs to.
Extensions should fire onDidChangeTreeData for any elements that need to be refreshed.
Parameter | Description |
---|---|
target: T | The target tree element that the drop is occurring on. When undefined, the target is the root. |
dataTransfer: DataTransfer | The data transfer items of the source of the drag. |
token: CancellationToken | A cancellation token indicating that the drop has been cancelled. |
Returns | Description |
void | Thenable<void> |

TreeItemCheckboxState of the tree item. onDidChangeTreeData should be fired when checkboxState changes.
collapsibleState?: TreeItemCollapsibleState
TreeItemCollapsibleState of the tree item.
command?: Command
The Command that should be executed when the tree item is selected.
Please use vscode.open
or vscode.diff
as command IDs when the tree item is opening
something in the editor. Using these commands ensures that the resulting editor will
appear consistent with how other built-in trees open editors.
Context value of the tree item. This can be used to contribute item specific actions in the tree.
For example, a tree item is given a context value as folder
. When contributing actions to view/item/context
using menus
extension point, you can specify context value for key viewItem
in when
expression like viewItem == folder
.
"contributes": {
"menus": {
"view/item/context": [
{
"command": "extension.deleteFolder",
"when": "viewItem == folder"

dragAndDropController?: TreeDragAndDropController<T>
An optional interface to implement drag and drop in the tree view.
manageCheckboxStateManually?: boolean
By default, when the children of a tree item have already been fetched, child checkboxes are automatically managed based on the checked state of the parent tree item.
If the tree item is collapsed by default (meaning that the children haven't yet been fetched) then child checkboxes will not be updated.
To override this behavior and manage child and parent checkbox state in the extension, set this to true
.
Examples where TreeViewOptions.manageCheckboxStateManually is false, the default behavior:
A tree item is checked, then its children are fetched. The children will be checked.
A tree item's parent is checked. The tree item and all of it's siblings will be checked.
- Parent
- Child 1
- Child 2 When the user checks Parent, the tree will look like this:
- Parent
- Child 1
- Child 2
- A tree item and all of it's siblings are checked. The parent will be checked.

UIKind
Possible kinds of UI that can use extensions.
Enumeration Members
Extensions are accessed from a desktop application.
Extensions are accessed from a web browser.
Uri
A universal resource identifier representing either a file on disk or another resource, like untitled resources.
Static
file(path: string): Uri
Create an URI from a file system path. The scheme
will be file
.
The difference between Uri.parse and Uri.file is that the latter treats the argument
as path, not as stringified-uri. E.g. Uri.file(path)
is not the same as
Uri.parse('file://' + path)
because the path might contain characters that are
interpreted (# and ?). See the following sample:
const good = URI.file('/coding/c#/project1');
good.scheme === 'file';
good.path === '/coding/c#/project1';
good.fragment === '';
const bad = URI.parse('file://' + '/coding/c#/project1');
bad.scheme === 'file';
bad.path === '/coding/c'; // path is now broken
bad.fragment === '/project1';
Parameter | Description |
---|---|
path: string | A file system or UNC path. |
Returns | Description |
Uri | A new Uri instance. |
from(components: {authority: string, fragment: string, path: string, query: string, scheme: string}): Uri
Create an URI from its component parts
See also Uri.toString
Parameter | Description |
---|---|
components: {authority: string, fragment: string, path: string, query: string, scheme: string} | The component parts of an Uri. |
Returns | Description |
Uri | A new Uri instance. |
joinPath(base: Uri, ...pathSegments: string[]): Uri
Create a new uri which path is the result of joining the path of the base uri with the provided path segments.
- Note 1:
joinPath
only affects the path component and all other components (scheme, authority, query, and fragment) are left as they are. - Note 2: The base uri must have a path; an error is thrown otherwise.
The path segments are normalized in the following ways:
- sequences of path separators (
/
or\
) are replaced with a single separator - for
file
-uris on windows, the backslash-character (``) is considered a path-separator - the
..
-segment denotes the parent segment, the.
denotes the current segment - paths have a root which always remains, for instance on windows drive-letters are roots
so that is true:
joinPath(Uri.file('file:///c:/root'), '../../other').fsPath === 'c:/other'
parse(value: string, strict?: boolean): Uri
Create an URI from a string, e.g. http://www.example.com/some/path
,
file:///usr/home
, or scheme:with/path
.
Note that for a while uris without a scheme
were accepted. That is not correct
as all uris should have a scheme. To avoid breakage of existing code the optional
strict
-argument has been added. We strongly advise to use it, e.g. Uri.parse('my:uri', true)
See also Uri.toString
Parameter | Description |
---|---|
value: string | The string value of an Uri. |
strict?: boolean | Throw an error when |
Returns | Description |
Uri | A new Uri instance. |
Constructors
new Uri(scheme: string, authority: string, path: string, query: string, fragment: string): Uri
Use the file
and parse
factory functions to create new Uri
objects.
Parameter | Description |
---|---|
scheme: string | |
authority: string | |
path: string | |
query: string | |
fragment: string | |
Returns | Description |
Uri |
Properties
Authority is the www.example.com
part of http://www.example.com/some/path?query#fragment
.
The part between the first double slashes and the next slash.
Fragment is the fragment
part of http://www.example.com/some/path?query#fragment
.
The string representing the corresponding file system path of this Uri.
Will handle UNC paths and normalize windows drive letters to lower-case. Also uses the platform specific path separator.
- Will not validate the path for invalid characters and semantics.
- Will not look at the scheme of this Uri.
- The resulting string shall not be used for display purposes but
for disk operations, like
readFile
et al.
The difference to the path-property is the use of the platform specific path separator and the handling of UNC paths. The sample below outlines the difference:
const u = URI.parse('file://server/c$/folder/file.txt');
u.authority === 'server';
u.path === '/c$/folder/file.txt';
u.fsPath === '\\serverc$\folder\file.txt';
Path is the /some/path
part of http://www.example.com/some/path?query#fragment
.
Query is the query
part of http://www.example.com/some/path?query#fragment
.
Scheme is the http
part of http://www.example.com/some/path?query#fragment
.
The part before the first colon.
Methods
Returns a JSON representation of this Uri.
Parameter | Description |
---|---|
Returns | Description |
any | An object. |
toString(skipEncoding?: boolean): string
Returns a string representation of this Uri. The representation and normalization of a URI depends on the scheme.
- The resulting string can be safely used with Uri.parse.
- The resulting string shall not be used for display purposes.
Note that the implementation will encode aggressive which often leads to unexpected,
but not incorrect, results. For instance, colons are encoded to %3A
which might be unexpected
in file-uri. Also &
and =
will be encoded which might be unexpected for http-uris. For stability
reasons this cannot be changed anymore. If you suffer from too aggressive encoding you should use
the skipEncoding
-argument: uri.toString(true)
.
Parameter | Description |
---|---|
skipEncoding?: boolean | Do not percentage-encode the result, defaults to |
Returns | Description |
string | A string representation of this Uri. |
with(change: {authority: string, fragment: string, path: string, query: string, scheme: string}): Uri
Derive a new Uri from this Uri.
let file = Uri.parse('before:some/file/path');
let other = file.with({ scheme: 'after' });
assert.ok(other.toString() === 'after:some/file/path');
Parameter | Description |
---|---|
change: {authority: string, fragment: string, path: string, query: string, scheme: string} | An object that describes a change to this Uri. To unset components use |
Returns | Description |
Uri | A new Uri that reflects the given change. Will return |
UriHandler
A uri handler is responsible for handling system-wide uris.
See also window.registerUriHandler.
Methods
handleUri(uri: Uri): ProviderResult<void>
Handle the provided system-wide Uri.
See also window.registerUriHandler.
Parameter | Description |
---|---|
uri: Uri | |
Returns | Description |
ProviderResult<void> |
ViewBadge
A badge presenting a value for a view
Properties
A label to present in tooltip for the badge.
The value to present in the badge.
ViewColumn
Denotes a location of an editor in the window. Editors can be arranged in a grid and each column represents one editor location in that grid by counting the editors in order of their appearance.
Enumeration Members
A symbolic editor column representing the column to the side of the active one. This value
can be used when opening editors, but the resolved viewColumn-value
of editors will always be One
, Two
, Three
,... or undefined
but never Beside
.
A symbolic editor column representing the currently active column. This value
can be used when opening editors, but the resolved viewColumn-value
of editors will always be One
, Two
, Three

The second editor column.
The third editor column.
The fourth editor column.
The fifth editor column.
The sixth editor column.
The seventh editor column.
The eighth editor column.
The ninth editor column.
Webview
Displays html content, similarly to an iframe.
Events
onDidReceiveMessage: Event<any>
Fired when the webview content posts a message.
Webview content can post strings or json serializable objects back to an extension. They cannot
post Blob
, File
, ImageData
and other DOM specific objects since the extension that receives the
message does not run in a browser environment.
Properties
Content security policy source for webview resources.
This is the origin that should be used in a content security policy rule:
`img-src https: ${webview.cspSource} ...;`;
HTML contents of the webview.
This should be a complete, valid html document. Changing this property causes the webview to be reloaded.
Webviews are sandboxed from normal extension process, so all communication with the webview must use
message passing. To send a message from the extension to the webview, use postMessage.
To send message from the webview back to an extension, use the acquireVsCodeApi
function inside the webview
to get a handle to the editor's api and then call .postMessage()
:
<script>
const vscode = acquireVsCodeApi(); // acquireVsCodeApi can only be invoked once
vscode.postMessage({ message: 'hello!' });
</script>
To load a resources from the workspace inside a webview, use the asWebviewUri method and ensure the resource's directory is listed in WebviewOptions.localResourceRoots.
Keep in mind that even though webviews are sandboxed, they still allow running scripts and loading arbitrary content, so extensions must follow all standard web security best practices when working with webviews. This includes properly sanitizing all untrusted input (including content from the workspace) and setting a content security policy.
options: WebviewOptions
Content settings for the webview.
Methods
asWebviewUri(localResource: Uri): Uri
Convert a uri for the local file system to one that can be used inside webviews.
Webviews cannot directly load resources from the workspace or local file system using file:
uris. The
asWebviewUri
function takes a local file:
uri and converts it into a uri that can be used inside of
a webview to load the same resource:
webview.html = `<img src="${webview.asWebviewUri(
vscode.Uri.file('/Users/codey/workspace/cat.gif')
)}">`;
postMessage(message: any): Thenable<boolean>
Post a message to the webview content.
Messages are only delivered if the webview is live (either visible or in the
background with retainContextWhenHidden
).
Parameter | Description |
---|---|
message: any | Body of the message. This must be a string or other json serializable object. For older versions of vscode, if an However if your extension targets vscode 1.57+ in the |
Returns | Description |
Thenable<boolean> | A promise that resolves when the message is posted to a webview or when it is dropped because the message was not deliverable. Returns A response of If you want confirm that a message as actually received, you can try having your webview posting a confirmation message back to your extension. |
WebviewOptions
Content settings for a webview.
Properties
enableCommandUris?: boolean | readonly string[]
Controls whether command uris are enabled in webview content or not.
Defaults to false
(command uris are disabled).
If you pass in an array, only the commands in the array are allowed.
Controls whether forms are enabled in the webview content or not.
Defaults to true if scripts are enabled. Otherwise defaults to false. Explicitly setting this property to either true or false overrides the default.
Controls whether scripts are enabled in the webview content or not.
Defaults to false (scripts-disabled).
localResourceRoots?: readonly Uri[]
Root paths from which the webview can load local (filesystem) resources using uris from asWebviewUri
Default to the root folders of the current workspace plus the extension's install directory.
Pass in an empty array to disallow access to any local resources.
portMapping?: readonly WebviewPortMapping[]
Mappings of localhost ports used inside the webview.
Port mapping allow webviews to transparently define how localhost ports are resolved. This can be used to allow using a static localhost port inside the webview that is resolved to random port that a service is running on.
If a webview accesses localhost content, we recommend that you specify port mappings even if
the webviewPort
and extensionHostPort
ports are the same.
Note that port mappings only work for http
or https
urls. Websocket urls (e.g. ws://localhost:3000
)
cannot be mapped to another port.
WebviewPanel
A panel that contains a webview.
Events
onDidChangeViewState: Event<WebviewPanelOnDidChangeViewStateEvent>
Fired when the panel's view state changes.
onDidDispose: Event<void>
Fired when the panel is disposed.
This may be because the user closed the panel or because .dispose()
was
called on it.
Trying to use the panel after it has been disposed throws an exception.
Properties
Whether the panel is active (focused by the user).
iconPath?: Uri | {dark: Uri, light: Uri}
Icon for the panel shown in UI.
options: WebviewPanelOptions
Content settings for the webview panel.
Title of the panel shown in UI.
viewColumn: ViewColumn
Editor position of the panel. This property is only set if the webview is in one of the editor view columns.
Identifies the type of the webview panel, such as 'markdown.preview'
.
Whether the panel is visible.
webview: Webview
Webview belonging to the panel.
Methods
Dispose of the webview panel.
This closes the panel if it showing and disposes of the resources owned by the webview.
Webview panels are also disposed when the user closes the webview panel. Both cases
fire the onDispose
event.
Parameter | Description |
---|---|
Returns | Description |
any |
reveal(viewColumn?: ViewColumn, preserveFocus?: boolean): void
Show the webview panel in a given column.
A webview panel may only show in a single column at a time. If it is already showing, this method moves it to a new column.
Parameter | Description |
---|---|
viewColumn?: ViewColumn | View column to show the panel in. Shows in the current |
preserveFocus?: boolean | When |
Returns | Description |
void |
WebviewPanelOnDidChangeViewStateEvent
Event fired when a webview panel's view state changes.
Properties
webviewPanel: WebviewPanel
Webview panel whose view state changed.
WebviewPanelOptions
Content settings for a webview panel.
Properties
Controls if the find widget is enabled in the panel.
Defaults to false
.
retainContextWhenHidden?: boolean
Controls if the webview panel's content (iframe) is kept around even when the panel is no longer visible.
Normally the webview panel's html context is created when the panel becomes visible
and destroyed when it is hidden. Extensions that have complex state
or UI can set the retainContextWhenHidden
to make the editor keep the webview
context around, even when the webview moves to a background tab. When a webview using
retainContextWhenHidden
becomes hidden, its scripts and other dynamic content are suspended.
When the panel becomes visible again, the context is automatically restored
in the exact same state it was in originally. You cannot send messages to a
hidden webview, even with retainContextWhenHidden
enabled.
retainContextWhenHidden
has a high memory overhead and should only be used if
your panel's context cannot be quickly saved and restored.
WebviewPanelSerializer<T>
Restore webview panels that have been persisted when vscode shuts down.
There are two types of webview persistence:
- Persistence within a session.
- Persistence across sessions (across restarts of the editor).
A WebviewPanelSerializer
is only required for the second case: persisting a webview across sessions.
Persistence within a session allows a webview to save its state when it becomes hidden
and restore its content from this state when it becomes visible again. It is powered entirely
by the webview content itself. To save off a persisted state, call acquireVsCodeApi().setState()
with
any json serializable object. To restore the state again, call getState()
// Within the webview
const vscode = acquireVsCodeApi();
// Get existing state
const oldState = vscode.getState() || { value: 0 };
// Update state
setState({ value: oldState.value + 1 });
A WebviewPanelSerializer
extends this persistence across restarts of the editor. When the editor is shutdown,
it will save off the state from setState
of all webviews that have a serializer. When the
webview first becomes visible after the restart, this state is passed to deserializeWebviewPanel
.
The extension can then restore the old WebviewPanel
from this state.
Methods
deserializeWebviewPanel(webviewPanel: WebviewPanel, state: T): Thenable<void>
Restore a webview panel from its serialized state
.
Called when a serialized webview first becomes visible.
Parameter | Description |
---|---|
webviewPanel: WebviewPanel | Webview panel to restore. The serializer should take ownership of this panel. The
serializer must restore the webview's |
state: T | Persisted state from the webview content. |
Returns | Description |
Thenable<void> | Thenable indicating that the webview has been fully restored. |
WebviewPortMapping
Defines a port mapping used for localhost inside the webview.
Properties
Destination port. The webviewPort
is resolved to this port.
Localhost port to remap inside the webview.
WebviewView
A webview based view.
Events
onDidChangeVisibility: Event<void>
Event fired when the visibility of the view changes.
Actions that trigger a visibility change:
- The view is collapsed or expanded.
- The user switches to a different view group in the sidebar or panel.
Note that hiding a view using the context menu instead disposes of the view and fires onDidDispose
.
onDidDispose: Event<void>
Event fired when the view is disposed.
Views are disposed when they are explicitly hidden by a user (this happens when a user right clicks in a view and unchecks the webview view).
Trying to use the view after it has been disposed throws an exception.
Properties
badge?: ViewBadge
The badge to display for this webview view. To remove the badge, set to undefined.
Human-readable string which is rendered less prominently in the title.
View title displayed in the UI.
The view title is initially taken from the extension package.json
contribution.
Identifies the type of the webview view, such as 'hexEditor.dataView'
.
Tracks if the webview is currently visible.
Views are visible when they are on the screen and expanded.
webview: Webview
The underlying webview for the view.
Methods
show(preserveFocus?: boolean): void
Reveal the view in the UI.
If the view is collapsed, this will expand it.
Parameter | Description |
---|---|
preserveFocus?: boolean | When |
Returns | Description |
void |
WebviewViewProvider
Provider for creating WebviewView
elements.
Methods
resolveWebviewView(webviewView: WebviewView, context: WebviewViewResolveContext<unknown>, token: CancellationToken): void | Thenable<void>
Resolves a webview view.
resolveWebviewView
is called when a view first becomes visible. This may happen when the view is
first loaded or when the user hides and then shows a view again.
Parameter | Description |
---|---|
webviewView: WebviewView | Webview view to restore. The provider should take ownership of this view. The
provider must set the webview's |
context: WebviewViewResolveContext<unknown> | Additional metadata about the view being resolved. |
token: CancellationToken | Cancellation token indicating that the view being provided is no longer needed. |
Returns | Description |
void | Thenable<void> | Optional thenable indicating that the view has been fully resolved. |
WebviewViewResolveContext<T>
Additional information the webview view being resolved.
Properties
Persisted state from the webview content.
To save resources, the editor normally deallocates webview documents (the iframe content) that are not visible.
For example, when the user collapse a view or switches to another top level activity in the sidebar, the
WebviewView
itself is kept alive but the webview's underlying document is deallocated. It is recreated when
the view becomes visible again.
You can prevent this behavior by setting retainContextWhenHidden
in the WebviewOptions
. However this
increases resource usage and should be avoided wherever possible. Instead, you can use persisted state to
save off a webview's state so that it can be quickly recreated as needed.
To save off a persisted state, inside the webview call acquireVsCodeApi().setState()
with
any json serializable object. To restore the state again, call getState()
. For example:
// Within the webview
const vscode = acquireVsCodeApi();
// Get existing state
const oldState = vscode.getState() || { value: 0 };
// Update state
setState({ value: oldState.value + 1 });
The editor ensures that the persisted state is saved correctly when a webview is hidden and across editor restarts.
WindowState
Represents the state of a window.
Properties
Whether the window has been interacted with recently. This will change immediately on activity, or after a short time of user inactivity.
Whether the current window is focused.
WorkspaceConfiguration
Represents the configuration. It is a merged view of
- Default Settings
- Global (User) Settings
- Workspace settings
- Workspace Folder settings - From one of the Workspace Folders under which requested resource belongs to.
- Language settings - Settings defined under requested language.
The effective value (returned by get) is computed by overriding or merging the values in the following order:
defaultValue
(if defined inpackage.json
otherwise derived from the value's type)globalValue
(if defined)workspaceValue
(if defined)workspaceFolderValue
(if defined)defaultLanguageValue
(if defined)globalLanguageValue
(if defined)workspaceLanguageValue
(if defined)workspaceFolderLanguageValue
(if defined)
Note: Only object
value types are merged and all other value types are overridden.
Example 1: Overriding
defaultValue = 'on';
globalValue = 'relative';
workspaceFolderValue = 'off';
value = 'off';
Example 2: Language Values
defaultValue = 'on';
globalValue = 'relative';
workspaceFolderValue = 'off';
globalLanguageValue = 'on';
value = 'on';
Example 3: Object Values
defaultValue = { a: 1, b: 2 };
globalValue = { b: 3, c: 4 };
value = { a: 1, b: 3, c: 4 };
Note: Workspace and Workspace Folder configurations contains launch
and tasks
settings. Their basename will be
part of the section identifier. The following snippets shows how to retrieve all configurations
from launch.json
:
// launch.json configuration
const config = workspace.getConfiguration(
'launch',
vscode.workspace.workspaceFolders[0].uri
);
// retrieve values
const values = config.get('configurations');
Refer to Settings for more information.

WorkspaceEditEntryMetadata
Additional data for entries of a workspace edit. Supports to label entries and marks entries as needing confirmation by the user. The editor groups edits with equal labels into tree nodes, for instance all edits labelled with "Changes in Strings" would be a tree node.
Properties
A human-readable string which is rendered less prominent on the same line.
iconPath?: Uri | ThemeIcon | {dark: Uri, light: Uri}
The icon path or ThemeIcon for the edit.
A human-readable string which is rendered prominent.
A flag which indicates that user confirmation is needed.
WorkspaceEditMetadata
Additional data about a workspace edit.
Properties
Signal to the editor that this edit is a refactoring.
WorkspaceFolder
A workspace folder is one of potentially many roots opened by the editor. All workspace folders are equal which means there is no notion of an active or primary workspace folder.
Properties
The ordinal number of this workspace folder.
The name of this workspace folder. Defaults to the basename of its uri-path
uri: Uri
The associated uri for this workspace folder.
Note: The Uri-type was intentionally chosen such that future releases of the editor can support
workspace folders that are not stored on the local disk, e.g. ftp://server/workspaces/foo
.
WorkspaceFolderPickOptions
Options to configure the behaviour of the workspace folder pick UI.

Set to true
to keep the picker open when focus moves to another part of the editor or to another window.
This setting is ignored on iPad and is always false.
An optional string to show as placeholder in the input box to guide the user what to pick on.
WorkspaceFoldersChangeEvent
An event describing a change to the set of workspace folders.
Properties
added: readonly WorkspaceFolder[]
Added workspace folders.
removed: readonly WorkspaceFolder[]
Removed workspace folders.
WorkspaceSymbolProvider<T>
The workspace symbol provider interface defines the contract between extensions and the symbol search-feature.
Methods
provideWorkspaceSymbols(query: string, token: CancellationToken): ProviderResult<T[]>
Project-wide search for a symbol matching the given query string.
The query
-parameter should be interpreted in a relaxed way as the editor will apply its own highlighting
and scoring on the results. A good rule of thumb is to match case-insensitive and to simply check that the
characters of query appear in their order in a candidate symbol. Don't use prefix, substring, or similar
strict matching.
To improve performance implementors can implement resolveWorkspaceSymbol
and then provide symbols with partial
location-objects, without a range
defined. The editor will then call
resolveWorkspaceSymbol
for selected symbols only, e.g. when opening a workspace symbol.
Parameter | Description |
---|---|
query: string | A query string, can be the empty string in which case all symbols should be returned. |
token: CancellationToken | A cancellation token. |
Returns | Description |
ProviderResult<T[]> | An array of document highlights or a thenable that resolves to such. The lack of a result can be
signaled by returning |
resolveWorkspaceSymbol(symbol: T, token: CancellationToken): ProviderResult<T>
Given a symbol fill in its location. This method is called whenever a symbol is selected in the UI. Providers can implement this method and return incomplete symbols from provideWorkspaceSymbols which often helps to improve performance.
Parameter | Description |
---|---|
symbol: T | The symbol that is to be resolved. Guaranteed to be an instance of an object returned from an
earlier call to |
token: CancellationToken | A cancellation token. |
Returns | Description |
ProviderResult<T> | The resolved symbol or a thenable that resolves to that. When no result is returned,
the given |
API Patterns
These are some of the common patterns we use in the VS Code API.
Promises
The VS Code API represents asynchronous operations with promises. From extensions, any type of promise can be returned, like ES6, WinJS, A+, etc.
Being independent of a specific promise library is expressed in the API by the Thenable
-type. Thenable
represents the common denominator which is the then method.
In most cases the use of promises is optional and when VS Code calls into an extension, it can handle the result type as well as a Thenable
of the result type. When the use of a promise is optional, the API indicates this by returning or
-types.
provideNumber(): number | Thenable<number>
Cancellation Tokens
Often operations are started on volatile state which changes before operations can finish. For instance, computing IntelliSense starts and the user continues to type making the result of that operation obsolete.
APIs that are exposed to such behavior will get passed a CancellationToken
on which you can check for cancellation (isCancellationRequested
) or get notified when cancellation occurs (onCancellationRequested
). The cancellation token is usually the last parameter of a function call and optional.
Disposables
The VS Code API uses the dispose pattern for resources that are obtained from VS Code. This applies to event listening, commands, interacting with the UI, and various language contributions.
For instance, the setStatusBarMessage(value: string)
function returns a Disposable
which upon calling dispose
removes the message again.
Events
Events in the VS Code API are exposed as functions which you call with a listener-function to subscribe. Calls to subscribe return a Disposable
which removes the event listener upon dispose.
var listener = function(event) {
console.log('It happened', event);
};
// start listening
var subscription = fsWatcher.onDidDelete(listener);
// do more stuff
subscription.dispose(); // stop listening
Names of events follow the on[Will|Did]VerbNoun?
pattern. The name signals if the event is going to happen (onWill) or already happened (onDid), what happened (verb), and the context (noun) unless obvious from the context.
An example from the VS Code API is window.onDidChangeActiveTextEditor
which is an event fired when the active text editor (noun) has been (onDid) changed (verb).
Strict null
The VS Code API uses the undefined
and null
TypeScript types where appropriate to support strict null checking.
Namespace for authentication.
