Hello, I am new to this list, but I am using Ant for a while. Thanks for your great job. Working with the ANTLR task I saw that it (the ANTLR task) is somehow limited when it tries to determine if the source grammar is "dirty" or not:
- It considers the output of ANTLR to be one file per grammar, while in fact there are 2 (or even 3): XxxParser.java, XxxParserTokenTypes.java and possibly XxxParserTokenTypes.txt. If any of one is missing, the grammar should be recompiled, which currently happens only for XxxParser.java. - An ANTLR file can contain more than one grammar (any combination of lexer, parser and tree parser grammars). Once again, multiple output files, and each of them missing should trigger the recompilation of the grammar. - ANTLR grammars can export/import token lists through "vocabulary files" - XxxTokenTypes.txt. If the imported file is newer than the grammar file, the grammar should be recompiled to include the correct tokens in generated code. The main problem lays in the method getGeneratedFile(), which returns only one file, while in fact we need two lists of files, ones that are results of the grammar, and should be *older* than the grammar, and a list of imported files, which should be *younger* than the grammar file. To extract all this information, I wrote a lexer/parser (using ANTLR and, of course, ANT :-) Now all works fine for me, and if you are interested I can post my sources. Unfortunately, they are not based on the latest version from CVS, but shouldn't be difficult to merge them. Please instruct me what to do next. Should I try to contact the maintainers of ANTLR directly? Or just post my sources here? Thanks, Bogdan __________________________________________________ Do You Yahoo!? Yahoo!
