## プロジェクトの歴史と使われ方

hgrep is a Rust command-line search presenter that aims to make local grep results look more like code-search output: matched regions are shown as syntax-highlighted snippets with useful surrounding context.

Its niche is deliberately narrow. Rather than replacing grep or ripgrep outright, it wraps a built-in subset of ripgrep or reads `grep -nH` and `rg -nH` output from standard input, then formats results with syntect or bat-backed printers.

### プロジェクトの歴史

The public release line begins with v0.1.x tags in October 2021. The README describes the original product idea as combining ripgrep-style search with bat-style highlighted display, while keeping a pipe-friendly mode for existing grep workflows.

The 0.2 and 0.3 series show the project tightening around terminal ergonomics: generated shell completions and man pages, binary release archives, static Linux builds, macOS and Windows support, and improved handling of color capability and encodings.

### 採用の歴史

The official README documents installation through release binaries, Homebrew, MacPorts, NetBSD pkgsrc/pkgin, Debian-style `.deb` packages, and Cargo. That packaging spread matches hgrep's role as a small terminal utility rather than a library platform.

The project also exposes feature flags so users can keep the built-in ripgrep search, the syntect printer, or the bat printer, which made it practical for package maintainers and source builders to tune dependency weight.

### 使われ方

Typical use is either `hgrep pattern path` for its built-in ripgrep subset or `rg -nH pattern path | hgrep` when the user wants full ripgrep behavior and hgrep only as the display stage.

hgrep is most useful when raw grep output has too little context: it groups nearby matches, chooses context around blank lines, applies syntax highlighting, and can generate shell completions or a manual page for packaged installs.

### パッケージ好きにとっての重要性

For package-manager users, hgrep is an example of the Rust CLI ecosystem's composable-search style: ripgrep supplies fast traversal and matching, bat/syntect supply readable code presentation, and the final binary stays scriptable.

It is also interesting as a dependency-shaping package. Builders can choose feature combinations to trade install time, binary size, and formatting behavior instead of carrying every optional printer path.

### タイムライン

- 2021: v0.1.x public tags establish the Rust CLI release line.
- 2021: v0.2.0 follows within weeks, continuing rapid terminal-search iteration.
- 2023: v0.3.0 updates syntect and bat integration and adds manual-page generation.
- 2024: v0.3.7 adds broader text-encoding support, including BOM-based detection.
- 2025: v0.3.9 adds Arm Windows release artifacts and additional language/theme support.

### Related projects

- ripgrep is the closest search-engine relative: hgrep can embed a subset of ripgrep or consume `rg -nH` output.
- bat and syntect are presentation relatives: hgrep uses them as alternative syntax-highlighted output paths.
- Traditional grep remains part of the workflow because hgrep can read `grep -nH` output from standard input.
