swpui (pronounced "swap UI") is a TUI utility to search and replace text, with a focus on ergonomics, speed and case-awareness in source code.

Dual-licensed under MIT or Apache 2.0.

cargo install swpui

cargo binstall swpui

nix profile install nixpkgs#swpui

Or run without installing:

nix run nixpkgs#swpui

$ swp

In regex mode, the replacement template can reference capture groups from the search pattern using $0 through $9:

• $0 expands to the entire match.
• $1-$9 expand to the corresponding capture groups (parenthesized sub-expressions in the pattern).
• $$ produces a literal $.
• References to groups that did not participate in the match expand to an empty string.

For example, searching for (\w+)_(\w+) and replacing with $2_$1 swaps the two halves of each snake_case pair.

Press Ctrl+g / Alt+g to switch to the glob filters view. The search and replace fields are hidden in favor of a field for and "include" and "exclude" globs list. Each input takes a comma-separated list of globs with gitignore matching semantics (same as ripgrep's -g flag).

• Include: when non-empty, only files matching at least one include glob are searched.
• Exclude: files matching any exclude glob are never searched.

Filters combine with the hidden/gitignore options and .swpignore files (an include glob does not re-include an ignored file). Active filters are shown in the status line at the bottom.

Default values for the options can be persisted in a swpui.toml (or .swpui.toml) file. On startup, swpui looks for them in:

1. The user config directory (~/.config/swpui/ on Linux and macOS, %APPDATA%\beeb\swpui\ on Windows).
2. Each directory from the filesystem root down to the directory where swpui was launched.

Settings closer to the working directory override settings from parents, and any field omitted from a file falls back to the value from the next layer up, ultimately defaulting to the built-in defaults shown below:

[options]
match-mode = "case-aware" # case-aware | literal | regex | regex-multiline
include-hidden = true
include-gitignored = false
include-globs = [] # e.g. ["src/**", "*.{rs,toml}"]
exclude-globs = [] # e.g. ["*_test.rs"]

In addition to .gitignore and .ignore files, swpui honors .swpignore files. These use the same gitignore syntax and are scoped per-directory: a .swpignore placed in any directory applies to that directory and its descendants.

• Case-aware replacement
• Regex support (incl. multiline)
• Multithreaded search
• Respects (git)ignore files
• Batch actions
• Capture groups replacement
• Toggle hidden files
• Toggle gitignored files
• Custom .swpignore files
• Mouse support
• Glob to include/exclude files

This tool was inspired by serpl, thanks for the great idea! It would also not have been possible without the amazing work put into ratatui and rat-widget, thank you! Finally, a massive thanks to the creator of ripgrep for their awesome work on ignore and regex.
