  • 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.
