Terence Parr 6314b7d31b -> becomes # for alt labels 2012-04-26 11:59:57 -07:00
Terence Parr 9c1e58db7c add {} in primary alt block to prevent ID|INT from becoming SET, which breaks code gen needs. 2012-03-27 16:21:01 -07:00
Terence Parr 9a0aaacbee rm k=1 chk to report early ambiguity. 2012-03-16 14:11:21 -07:00
Terence Parr 102980dffd make T.g same 2012-03-14 13:20:24 -07:00
Terence Parr ae08867ff3 alter visitTerminal interface, add visitErrorNode. 2012-02-26 22:07:45 -08:00
Terence Parr 8a34176d82 added listener unit tests. fixed bug that didn't create ctx getters properly for recursive rules. added Symbol extends Token to parse tree stuff. added visitTerminal to Visitor. recursive alts now track their original, unedited AltAST subtree so we can properly count rule refs etc... later. dup of RuleRefAST was making wrong node. don't gen dispatch methods if no listener. 2012-02-22 12:44:33 -08:00
parrt a923ad8765 Major update to v4. I backed out a change I made on Christmas then mistakenly prevented any lexer DFA creation. Per http://www.antlr.org/wiki/display/~admin/2011/12/29/Flaw+in+ANTLR+v3+LL%28*%29+analysis+algorithm I fixed a major flaw in ANTLR's notion of context. To do that, I needed to create a new LoopEndState, with all of its fanout to the serialization and parser ATN construction. got a very good start on ParserATNPathFinder, which uses basic recursion to find all possible paths and return a tree with the possibilities. I left it in the condition where he would sometimes loop forever; it needs to track sets of configurations in the busy set; it using states at the moment. added a new signal from the interpreter: reportAttemptingFullContext. I fixed a bug where configuration sets derived from a configuration that had reachesIntoOuterContext>0 were not being considered as dipping into the outer context. The ambiguity checker needed to switch so that a check for exact matches not suffixes when doing full context. It's faster at the very least for full context. added some more support routines to DFA. Added TraceTree in support of the new ParserATNPathFinder.

parrt 299c29d927 more lexer rule specialization in parser. got antlr almost back to working with new [Aa] notation in lexer.

 2011-12-26 17:09:01 -08:00
parrt d9efffd104 Add [abc] syntax to allow set of char in lexer; args aren't allowed so unambig.

 2011-12-26 15:58:40 -08:00
parrt 6fa5e52d5e added => skip, channel(99), more, mode(xx), push(xx), pop lexer syntax. separated lexer rules from others in parser / AST now.

parrt 80fd90d363 rm'd epsilon transition in ATN after rule refs. 
[git-p4: depot-paths = "//depot/code/antlr4/main/": change = 9518]
 2011-12-03 14:52:24 -08:00
parrt f08e8fc098 predTransition was not passing along predicate properly. rm'd unneeded parameter. pass null if ctx independent pred. added 2 unit tests for non outer ctx check.

 2011-12-03 14:12:06 -08:00
parrt ae74881de6 strip epsilons between alternative elements and also stripped the final epsilons before block ends. added an ATN visitor for general use. updated all of the unit tests so they pass new smaller ATNs. had to do some work in the serialization and deserialization to handle state numbers without state information. did not want to reorder state numbers during optimization.

parrt e00fa44996 Got validating and disambiguating predicates the way I want; widespread changes. DFAStates now have a list of predicate/alt pairs that they can test at except states. renamed Java.g4 to JavaLR.g4. LL(1) analysis did not fail when it's all predicates, which it must.

parrt a1c682434d removes the individual stacks to track rule invocations. $a::x now looks up the context stack for rule index RULE_a. they're not done very often and so it's better to say all of the overhead pushing and popping the contexts.

 2011-09-11 16:12:01 -08:00
parrt bf19465437 Got a rule labels added to the tree and also altered code generation so that it pays attention to the labels. fairly major surgery but it's a nice refactoring.
