This is a human, WIP, and clean implementation of an AWK interpreter, written in Rust and compatible with GNU's AWK (gawk) bug-for-bug. Expected to be production-ready before Ubuntu 26.10. Made with love.

State of the Repo

The lexer is pretty much done; however, it should track the span of the tokens so we can produce contextual error messages in the parser, and it is also lacking a POSIX-compatibility mode (trivial). The parser is mostly done, although it probably has some rough edges, and the preprocessor is TBD; also, the Pratt routine is a bit spaghetti and should be refactored (trivial). The interpreter is also TBD; work on it will be started once we get good testing on the parser. Expect this to be a fast-paced repo.
