Thrax - Release 1.2.4

  • Makes "#" a comment character for StringFiles: anything from "#" to the end of the line is now a comment. If you want a real "#", escape it with "\".
  • Adds a RuleCascade to the library to make it easier to deal with the common construct of a cascade of rules. (Only relevant if you develop code using the Thrax libraries.)
  • Better error reporting for "cannot parse character" error.
  • Adds ":" as a bash-friendly alternative to "$" when specifying a (M)PDT/parens(/assignments) combination.

Thrax - Release 1.2.3

Thrax - Release 1.2

  • Added interface to multi-pushdown transducer (MPDT) functionality from OpenFst.
  • Added interface to Replace class in OpenFst.
  • Adds --show_details flag to thraxrewrite-tester. When it is set and when multiple rules are specified, the tool will show the output of each individual rule. Useful when trying to find which rule caused a problem.
  • Raises a warning if more than one definition is given for a function.

  • Generated labels (enclosed in "[]") may no longer be single-character.

Thrax - Release 1.0

  • Removed dependency on ICU for UTF8 string parsing: --with-icu configuration flag no longer needed and OpenFst library version 1.3.1 or above is required.
  • Function definitions may now be interleaved with the rest of the body in grammars.
  • Support for standard (tropical), log and log64 arc types (flag --arc_type).
  • --save_symbols flag to thraxcompiler allows for symbol tables to be stored in the compiled fsts.
  • thraxmakedep supports --arc_type and --save_symbols flags.
  • StringFile function now supports construction of both acceptors and transducers. Strings may be compiled in byte or utf8 mode, or with a user-specified symbol table.
  • The --rule flag to thraxrewrite-tester is now --rules. Supports a comma-separated list of rule names, which are to applied in sequence to the input.
  • Project added as callable function.
  • Various optimizations to CDRewrite and elsewhere.
  • Fixed bug in how symbol tables are saved (1.0.1)
  • Fixed bug in treatment of symbol tables with StringFile
