scheme@gentoo.org Gentoo Scheme Project NYACC, for Not Yet Another Compiler Compiler, is set of guile modules for generating parsers and lexical analyzers. It also provides sample parsers and pretty-printers using SXML trees as an intermediate representation. It provides a decent C parser and a `FFI Helper' tool to help create Guile Scheme bindings for C-based libraries. It provides (partially implemented) compilers based on above mentioned parsers to allow execution with Guile as extension languages.
