## 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.
