MatrixDevConventions

This page is intended to provide a catalogue of global variables and other information of use to Matrix developers. These global variables should be used rather than repeating the information (for maintainability).

Lexical types

In gmcs.linglib.lexbase:

# all types of lexical items (on lexicon page)
ALL_LEX_TYPES = ['noun', 'verb', 'det', 'aux', 'adj']

# types used for lexical rules (verb and aux are merged)
LEXICAL_CATEGORIES = ['noun', 'verb', 'det', 'adj']

Choices file version

In gmcs.choices, in the definition of the class ChoicesFile:

######################################################################
  # Conversion methods: each of these functions assumes the choices
  # file has already been loaded, then converts an older version into
  # a newer one, updating both old key names and old value names.
  # These methods can be called in a chain: to update from version 2
  # to 5, call convert_2_to_3, convert_3_to_4, and convert_4_to_5, in
  # that order.
  #
  # The mehods should consist of a sequence of calls to
  # convert_value(), followed by a sequence of calls to convert_key().
  # That way the calls always contain an old name and a new name.
