Readme for brassica-0.2.0

[back to package description]



Brassica is a new sound change applier. Its features include:

  • Can be used interactively both online and as a desktop application, or non-interactively in batch mode on the command-line or as a Haskell library
  • Natively supports the MDF dictionary format, also used by tools including SIL Toolbox and Lexique Pro
  • First-class support for multigraphs
  • Easy control over rule application: apply sound changes sporadically, right-to-left, between words, and in many more ways
  • Live preview and control over output highlighting let you try out sound changes quickly and easily
  • Highlight and visualise results in numerous ways
  • Category operations allow phonetic rules to be written in both featural and character-based ways
  • Support for ‘features’ lets rules easily manipulate stress, tone and other suprasegmentals
  • Comes with a paradigm builder for quickly investigating inflectional and other patterns
  • Rich syntax for specifying phonetic rules, including wildcards, optional elements and more

And many more!

See the documentation for details on Brassica usage.
