## プロジェクトの歴史と使われ方
Oniguruma is a BSD-licensed C regular-expression engine known for rich syntax and unusually broad character-encoding support. It became infrastructure for language runtimes, multibyte text processing, and editor syntax-highlighting systems.
### プロジェクトの歴史
The upstream README describes Oniguruma as a modern and flexible regular-expression library that combines features traditionally found in different regex implementations. A key design point is that character encoding can be specified per regular-expression object, with supported encodings ranging from ASCII and UTF families to EUC variants, Shift_JIS, Big5, GB18030, KOI8-R, CP1251, and ISO-8859 variants.
The project continued through 6.x releases with Unicode and API work: 6.9.6 added compatibility and safety-related options, 6.9.7 added callback and Python syntax APIs, 6.9.8 updated to Unicode 14.0.0 and fixed OSS-Fuzz findings, 6.9.9 updated to Unicode 15.1.0, and 6.9.10 updated to Unicode 16.0 and added the (*SKIP) operator. The README states that the project ended on April 24, 2025.
### 採用の歴史
Oniguruma's adoption came from being useful where byte-oriented regex engines were not enough. PHP's mbstring installation manual says Oniguruma is necessary for multibyte regular-expression functions and that PHP 7.4.0 switched to pkg-config detection of the external libonig library after earlier bundled use.
The editor ecosystem also standardized on Oniguruma syntax. Microsoft's vscode-textmate README says TextMate grammars use the Oniguruma dialect and that the library is used in VS Code; the VS Code extension API guide likewise says TextMate grammars rely on Oniguruma regular expressions.
### 使われ方
C developers include oniguruma.h, link with libonig, and choose among the native Oniguruma API plus GNU and POSIX-compatible APIs. The upstream README includes sample programs for callouts, encodings, named groups, POSIX usage, scanning, syntax tests, and user-defined Unicode properties.
Downstream users often never call libonig directly. PHP developers touch it through mb_ereg and related mbstring regex functions, while editor-extension authors touch its syntax through TextMate grammar patterns consumed by VS Code and compatible tooling.
### パッケージ好きにとっての重要性
Oniguruma is a classic package-graph library: small from a user-interface perspective, but large in dependency impact. It sits under PHP multibyte regex, TextMate grammar tokenization, VS Code-related tooling, and multiple language or editor stacks, so packaging updates can ripple into builds, syntax highlighting, and security maintenance.
### タイムライン
- PHP 7.4.0: PHP's mbstring build switched to pkg-config detection for libonig, while the manual notes prior bundled use.
- 2020-2022: 6.9.6 through 6.9.8 added API work, Unicode 14.0.0 support, and fixes from OSS-Fuzz and Coverity.
- 2024-2025: 6.9.9 and 6.9.10 updated Unicode support to 15.1.0 and 16.0.
- April 24, 2025: the upstream README states that the Oniguruma project ended.
### Related projects
- Oniguruma is the upstream ancestor of Onigmo. It is also tied to PHP mbstring, TextMate grammars, VS Code's TextMate tokenizer stack, and package names such as libonig on Linux distributions.
