OpenToken version 4.0a released

Stephen Leake has released OpenToken version 4.0a.

The OpenToken is a facility for performing token analysis and parsing within the Ada language.

Some of the changes in this version include:

  • Fixed major bug in LALR parser generator related to which production
    gets the accept action. This bug made many small grammars unworkable;
    now they all work.
  • Syntax errors reported by LR and recursive descent parsers include the
    list of expected tokens.
  • The examples have been improved to more clearly demonstrate the
    differences and similarities between LR parsing and recursive descent
    parsing with OpenToken.

A full announcement was made by Stephen at comp.lang.ada.
