## プロジェクトの歴史と使われ方

jvgrep is a grep-like command-line search tool by Yasuhiro Matsumoto for Japanese Vim users. It searches files written in Japanese encodings and can be set as Vim's `grepprg`.

### プロジェクトの歴史

The jvgrep repository was created on 2011-08-19. Its README describes a focused problem: searching text in files written with Japanese encodings such as ISO-2022-JP, EUC-JP, Shift_JIS/CP932, UTF-8, and UTF-16.

The project has long stayed small and utilitarian. Its public releases show continued maintenance across Go toolchain eras, including v5-series releases and a v5.8.16 release on 2026-04-13.

### 採用の歴史

jvgrep's adoption appears narrow and language-community-specific. The input package metadata lists Homebrew packaging, and the README documents `brew install jvgrep` for macOS along with Go installation commands.

Its value is strongest for Vim users and Japanese text workflows where ordinary grep behavior can be uncomfortable around legacy encodings and multibyte regular expressions.

### 使われ方

jvgrep is used like grep with options for recursive search, fixed-string or regular-expression matching, color, line numbers, match counts, and encoding selection. Users can set `JVGREP_ENCODINGS` and `JVGREP_OUTPUT_ENCODING` to tune input and output encoding behavior.

In Vim, adding `set grepprg=jvgrep` makes Vim's grep integration call jvgrep instead of the platform grep.

### パッケージ好きにとっての重要性

jvgrep is package-nerd interesting because it preserves a local need that generic Unix tools often flatten: Japanese encodings, Vim integration, and grep ergonomics in one small Go command.

It also reflects a common Homebrew pattern: small, durable utilities with a very specific audience can still be worth packaging because they solve one awkward workflow cleanly.
