Marpa is a Tcl binding to libmarpa, in the spirit of the Marpa::R2 perl binding.

libmarpa is an Earley parser engine, with both Leo and Aycock-Horspool fixes.

Official example parsers/languages (in the `languages/` directory of the sources):

   * json, with large testsuite

Examples in work branches

   * heredoc - Basic demonstration of L0 parse events to implement here documents.

   * doctools - Larger demonstration of L0 parse events to implement macros and include files (doctools commands `vset` and `include`). Passes a torture test using the Tcllib manpages.
