It reads yacc grammars and emits Go parsers, while adding compatibility and diagnostics features beyond the older `go tool yacc` style. ### 项目历史 The modernc.org implementation begins in public history in November 2014. Its source comments state that it uses portions of code previously published in the Go tool `yacc` program, while the Go tools documentation describes that upstream goyacc as largely transliterated from Inferno's Limbo version, itself largely transliterated from the Plan 9 C version. The project moved its import path and repository root to modernc.org in 2018, and pkg.go.dev records `gitlab.com/cznic/goyacc` as the repository for the modernc.org module. ### 采用历史 goyacc is part of a long Unix parser-generator tradition adapted for Go. The Go project used goyacc as an example in the Go 1.4 `go generate` announcement, showing how generated parsers fit into Go package maintenance even though generation is run explicitly by package authors. ### 使用方式 The command accepts a yacc input file or standard input and writes a Go parser, defaulting to `y.go`, with options for the symbol prefix, parser report output, follow sets, conflict explanations, and generated error examples. Generated parsers use a Go lexer interface instead of C yacc globals. ### 为什么软件包爱好者会关心 For package maintainers, goyacc is a compact bridge between old compiler-construction workflows and Go modules: grammars can live beside Go source, generation can be driven by `go generate`, and the installed binary is small enough to package directly in Homebrew. ### 时间线 - 2014: modernc.org/goyacc public history begins and records the initial release work. - 2014: Go 1.4 introduces `go generate`, with goyacc used as a code-generation example. - 2015: The modernc.org command adds generated error-message support via examples. - 2017: The command adds follow-set reporting. - 2018: The project moves its repository root to modernc.org and tags v1.0.0. - 2023: v1.0.3 tag updates dependencies. ### Related projects - golang.org/x/tools/cmd/goyacc is the Go tools implementation in the same yacc-for-Go lineage. - Plan 9 yacc and Inferno yacc are earlier implementations named in the Go tools documentation. - modernc.org/y and modernc.org/parser/yacc are related modernc parser packages used by the command. ### 来源 - - - - ## 安全说明 narrow executable package without higher-risk signals. - **Geiger 风险:** 绿色 / 低 - narrow executable package without higher-risk signals ## 源数据库详情 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** goyacc - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## 相关链接 - [Terminal utility packages](https://www.automicvault.com/zh-hans/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/zh-hans/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/zh-hans/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Language runtime packages](https://www.automicvault.com/zh-hans/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [go](https://www.automicvault.com/zh-hans/pkg/brew/go/) - Build dependency declared by Homebrew. - [bison](https://www.automicvault.com/zh-hans/pkg/brew/bison/) - Shares av.db curated category or tags: cli, developer-tools, parser-generator, parser-generators, yacc. - [antlr](https://www.automicvault.com/zh-hans/pkg/brew/antlr/) - Shares av.db curated category or tags: cli, developer-tools, parser-generator, parser-generators. - [lemon](https://www.automicvault.com/zh-hans/pkg/brew/lemon/) - Shares av.db curated category or tags: cli, developer-tools, parser-generator, parser-generators. - [packcc](https://www.automicvault.com/zh-hans/pkg/brew/packcc/) - Shares av.db curated category or tags: cli, developer-tools, parser-generator, parser-generators. - [byacc](https://www.automicvault.com/zh-hans/pkg/brew/byacc/) - Shares av.db curated category or tags: cli, developer-tools, parser-generator, yacc. - [aurora](https://www.automicvault.com/zh-hans/pkg/brew/aurora/) - Shares av.db curated category or tags: cli, developer-tools, go. - [bed](https://www.automicvault.com/zh-hans/pkg/brew/bed/) - Shares av.db curated category or tags: cli, developer-tools, go. - [bnfc](https://www.automicvault.com/zh-hans/pkg/brew/bnfc/) - Shares av.db curated category or tags: cli, developer-tools, parser-generator. ## Combined YAML source View the package source record on GitHub.
