How does the Go1 compiler work?

Question

I went about Go for about a month for a school project, and I noticed packages go / ast, go / token, go / parser, etc. in the src / pkg / go folder. However, the gc compiler was based on C files located in src / cmd / gc.

My question is about the new go command in Go1, which builds and runs programs: does this tool depend on the packages I referenced above? those. if I add a new token to /go/token/token.go, will it be recognized by the new go compiler?

Answer 1

The Go compiler is written in pure C and does not use packages under go/. In the Go source tree, his lexer lives in src / cmd / gc / lex.c, and his Bison grammar lives in src / cmd / gc / go.y.
