## Projektgeschichte und Nutzung

modernc.org/goyacc is Jan Mercl's Go parser-generator command derived from the Go toolchain's goyacc lineage. It reads yacc grammars and emits Go parsers, while adding compatibility and diagnostics features beyond the older `go tool yacc` style.

### Projektgeschichte

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.

### Adoptionsgeschichte

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.

### Wie es verwendet wird

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.

### Warum Paket-Nerds sich dafür interessieren

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.
