I have used PCCTS before, first time am using ANTLR. I have a grammar for a data structure language which is line oriented with mostly optional rules. The rules must be in the specified order when present. start_rule: (rule1)? (rule2)? (rule3)* (rule4)? . . (rule80)? ; ANTLR generates the lexer code ok, but never finishes the parser code generation. I have waited as long as 8 hours, but only the first section of code is generated. Any ideas, is this a known bug in ANTLR? Thanks in advance.    More>>
