history
Project history and usage
srgn is a Rust command-line search and transformation tool that combines regular-expression scopes with optional syntax-aware scopes based on programming-language grammars. Its author characterizes it as a mix of `tr`, `sed`, `ripgrep`, and tree-sitter.
Project history
The public repository was created in 2023 and released v0.1.0 that October. The README records that its earliest core was a Rust rewrite of a tool devoted to German character substitutions; it then expanded into a general code-aware search and transformation utility.
Adoption history
The official installation guide documents release binaries, cargo-binstall, Homebrew, Nix and a repository flake, MacPorts, and compilation through Cargo. The package metadata additionally records a Pacman package, giving srgn unusually broad distribution for a focused refactoring CLI.
How it is used
srgn can search or transform stdin and files with regular expressions, then narrow operations to syntax-aware language scopes. Actions include replacement, case conversion, deletion, squeezing, and language-specific transformations, and shell completions are built into the CLI.
Why package nerds care
srgn sits between traditional Unix text filters and IDE refactoring: it preserves a composable command-line interface while using parsers to select structural code regions. Its prebuilt binaries and presence across Cargo, Homebrew, Nix, MacPorts, and Pacman make it especially accessible to polyglot CLI users.
Timeline
- 2023: Official repository created.
- 2023: v0.1.0 published.
- 2025: v0.14.0 changed replacement syntax to reduce accidental destructive use.
- 2026: v0.14.2 published.
Related projects
- The README positions srgn alongside tr, sed, ripgrep, and tree-sitter while distinguishing its combination of regex actions and grammar-aware scopes.
