cfgrep is an attempt to produce a grep-like program that uses regular expressions extended to describe context-free grammars. The largest part of the project is the C++ library developed to process those expressions.

Features

  • Compatibility with GNU grep's extended regular expressions
  • #n dynamic reference system, allowing to recursively call parenthesized groups
  • Pretty-printer for easy visualization of expressions, represented as an Abstract Syntax Tree
  • Expression debugger, representing the evaluation process as a tree. Useful for understanding why a complex expression does not work.
  • Most of the features of the GNU grep will be implemented.
