  "github_readme_excerpt": "Oniguruma\n=========\n## **This project ended on April 24, 2025.**\n\n## **The only open source software attacked on Google search in Japan.** [(Issue #234)](https://github.com/kkos/oniguruma/issues/234)\n\n\nhttps://github.com/kkos/oniguruma\n\nOniguruma is a modern and flexible regular expressions library. It\nencompasses features from different regular expression implementations\nthat traditionally exist in different languages.\n\nCharacter encoding can be specified per regular expression object.\n\nSupported character encodings:\n\n  ASCII, UTF-8, UTF-16BE, UTF-16LE, UTF-32BE, UTF-32LE,\n  EUC-JP, EUC-TW, EUC-KR, EUC-CN,\n  Shift_JIS, Big5, GB18030, KOI8-R, CP1251,\n  ISO-8859-1, ISO-8859-2, ISO-8859-3, ISO-8859-4, ISO-8859-5,\n  ISO-8859-6, ISO-8859-7, ISO-8859-8, ISO-8859-9, ISO-8859-10,\n  ISO-8859-11, ISO-8859-13, ISO-8859-14, ISO-8859-15, ISO-8859-16\n\n* GB18030: contributed by KUBO Takehiro\n* CP1251:  contributed by Byte\n* doc/SYNTAX.md: contributed by seanofw\n* doc/onig_syn_md.c: tonco-miyazawa\n\n\nNotice (from 6.9.6)\n-------------------\nWhen using configure script, if you have the POSIX API enabled in an earlier version (disabled by default in 6.9.5) and you need application binary compatibility with the POSIX API, specify \"--enable-binary-compatible-posix-api=yes\" instead of \"--enable-posix-api=yes\". Starting in 6.9.6, \"--enable-posix-api=yes\" only supports source-level compatibility for 6.9.5 and earlier about POSIX API. (Issue #210)\n\n\nMaster branch\n-------------\n* Unicode property \\pC, \\pL, \\pM, \\pN, \\pP, \\pS, \\pZ\n\n\nVersion 6.9.10\n--------------\n* Update Unicode version 16.0\n* Add new operator (*SKIP)    (PR#299)\n* Fixed: ONIG_SYN_CONTEXT_INDEP_REPEAT_OPS not working for ^* pattern (Issue #292)\n\n\nVersion 6.9.9\n-------------\n* Update Unicode version 15.1.0\n* NEW API: ONIG_OPTION_MATCH_WHOLE_STRING\n* Fixed: (?I) option was not enabled for character classes (Issue #264).\n* Changed specification to check for incorrect POSIX bracket (Issue #253).\n* Changed [[:punct:]] in Unicode e",

  "why_use_this": "Oniguruma provides advanced regex features across diverse character encodings, making it essential for applications handling Japanese, CJK, and legacy text. It\u0027s a build dependency for tools like Ruby (default regex engine) and other interpreters that need robust, encoding-aware pattern matching. Use it if you need POSIX or Oniguruma syntax with character-set flexibility beyond standard libc regex."
