YAPB: Yet Another Parser Builder

A programmable parser builder system

• Allows to write LALR(1) parser specifications in Haskell
• Provides an automatic syntax completion method

Library, tools, and examples

• yapb: a library for a programmable parser builder system
• yapb-exe: a wrapper interface to YAPB
• conv-exe: a grammar format utility for conversion of a readable grammar (.lgrm) format into the Haskell data format (.grm)
• Examples:
  • parser-exe: an arithmetic parser
  • syncomp-exe: a syntax completion server for Emacs

Download, build, and test
