CLI tool to help you analyze code usage in your project.

Flashlight allows you to perform searches that would be difficult with normal string or regex searching such as:

• Find all imports from react that imported useMemo
• Find all <Button> tags with the attribute type="primary"

Regex searches can work for this at times, but it becomes very complex when imports or tags span multiple lines. Flashlight provides a much easier way to perform these searches.

You can install Flashlight by running the install script which will download the latest release.

curl -LSfs https://go.mskelton.dev/flashlight/install | sh

Or you can build from source.

git clone git@github.com:mskelton/flashlight.git
cd flashlight
cargo install --path .

Searches for all imports for a given import source.

flashlight imports react

You can also search for a specific import specifier.

flashlight imports react useState

Searches for all JSX elements with the given name.

flashlight tags Button

You can also search for elements with a specific attribute or attribute/value pair.

flashlight tags Button variant
flashlight tags Button variant=primary

By default, flashlight uses the current working directory to search. You can change the working directory using the --cwd argument.

flashlight --cwd ./packages/a imports react

You can customize the output format based on your use case. The supported formats are:

• default - The default console format
• json - Formats the output as JSON
• quickfix - Formats the output as a Vim quickfix list (alias vi)

flashlight --format json imports react
