{"name":"bison","summary":"Yacc-compatible parser generator","description":"Bison is a general-purpose parser generator that converts an\nannotated context-free grammar into an LALR(1) or GLR parser for\nthat grammar.  Once you are proficient with Bison, you can use\nit to develop a wide range of language parsers, from those used\nin simple desk calculators to complex programming languages.\n\nBison is upward compatible with Yacc: all properly-written Yacc\ngrammars ought to work with Bison with no change.  Anyone\nfamiliar with Yacc should be able to use Bison with little\ntrouble.  You need to be fluent in C or C++ programming in order\nto use Bison.","homepage_url":"https://www.gnu.org/software/bison/","license":"GPL-3.0-or-later","attribute_paths":["bison"],"releases":[{"version":"3.8.2","last_updated":"2026-09-29T03:29:29Z","platforms":[{"arch":"arm64","os":"macOS","system":"aarch64-darwin","attribute_path":"bison","commit_hash":"b6c8664de9b6cc07fe5666a29f91884ba81197c4","date":"2026-09-29T03:29:29Z","outputs":[{"name":"out","path":"/nix/store/sjp0zi3b8qmhlm058qarkzvs60dq60ih-bison-3.8.2","default":true}],"broken":false,"insecure":false},{"arch":"arm64","os":"Linux","system":"aarch64-linux","attribute_path":"bison","commit_hash":"b6c8664de9b6cc07fe5666a29f91884ba81197c4","date":"2026-09-29T03:29:29Z","outputs":[{"name":"out","path":"/nix/store/d5msam55ljqzmri8d2ijdxxpjlgbycnj-bison-3.8.2","default":true}],"broken":false,"insecure":false},{"arch":"x86-64","os":"macOS","system":"x86_64-darwin","attribute_path":"bison","commit_hash":"3d46470bb3030020f7e1361f33514854f5bfa86d","date":"2026-06-27T07:37:20Z","outputs":[{"name":"out","path":"/nix/store/nm0s5xsvvijy5f9b5zx2y1hfgfdyb26y-bison-3.8.2","default":true}],"broken":false,"insecure":false},{"arch":"x86-64","os":"Linux","system":"x86_64-linux","attribute_path":"bison","commit_hash":"b6c8664de9b6cc07fe5666a29f91884ba81197c4","date":"2026-09-29T03:29:29Z","outputs":[{"name":"out","path":"/nix/store/xrbwwd9zjvalag6hlxbrvgyb9y1wvfdn-bison-3.8.2","default":true}],"broken":false,"insecure":false}],"platforms_summary":"Linux
