yagg

'yagg' generates all strings of a user-specified length. The YACC-like language grammar file provides the grammar productions for string generation and optional action blocks that perform context-sensitive checks in order to limit the generated strings. The LEX-like terminal generator file provides specifications that tell the program how to generate strings for terminals in the grammar.

If you already have a YACC or Bison parser file, you need only to add "unaction" blocks to allow the recursive generator to undo the side effects of the action blocks. If you already have a LEX or FLEX lexer input file, you need only remove extraneous code and replace any regular expressions with one of the terminal generator specifications.
