Vocabulary

Contents

• This covers basically everything about individual words themselves.
• There’s a handful of various MC (Meaning Codes) that are used everywhere. These seem self-explanatory.
• The vocabulary_entry struct:
  | Field | Description |
  | ----------------------------------- | -------------------------------------------------------------- |
  | flags | Meaning Codes, see above |
  | literal_number_value | Shorthand evaluation of this word as a number |
  | exemplar, raw_exemplar | Examples of the vocabulary which I’ve still not found a use of |
  | hash, next_in_vocab_hash | Some hash table information |
  | lower_case_form,upper_case_form | For words where the surprise upper case might mean something |
• Inform TODO list - find wherever these exemplar fields are used.
• A bunch of default punctuation is made first in Words Module, I guess to ensure it’s at the start of the hash table bucket?
• identify_word is the main entry point of adding new words, which is called via the Lexer and apparently also in Numbered Words?
  • entry_for_text either adds it or looks it up.
  • And creates a new entry for it .
  • If we are using the Excerpt Meanings then we have a callback here.
  • For the most part the upper_case_form seems to be unused, except by calling Vocabulary::make_case_sensitive which happens in Excerpt Meanings .
• Most of this module is creating their own hash table and access functions.
