项目历史

Comby's documentation presents the core idea as lightweight matching of syntactic structures such as balanced delimiters, strings, and comments across many languages. The README frames it as a practical alternative when regular expressions become fragile for nested code constructs.

采用历史

The official README documents Homebrew installation on macOS, binaries for Ubuntu-like Linux systems, Docker images, Windows use through WSL, and source builds through OCaml/opam. The supplied package-manager metadata lists Homebrew and Nix, while the upstream distribution story emphasizes prebuilt binaries and containers.

使用方式

Users write templates with holes such as `:[condition]` to match code structures and replacements that preserve or transform matched parts. Comby is commonly used for large mechanical code changes, interactive review of rewrites, and language-aware searches where plain `sed` or regexes are too coarse.

为什么软件包爱好者会关心

Comby matters to package nerds because it packages a source-to-source transformation engine as a single CLI spanning many languages. Its OCaml implementation, PCRE linkage, binary distribution, Docker image, and Homebrew/Nix formulas make it a useful case study in shipping a specialized developer tool beyond one language ecosystem.
