AA.g fix playground 2012-09-29 17:02:33 -07:00
Bar.java add ctx cache to merge op. now i get optimal graph it seems. doesn't seem longer for java.* with JavaLR. still landmine in Pattern.java, Foo.java. Made toDOTString sort predctx nodes by id for repeatable tests. updated unit tests. 2012-07-24 16:26:01 -07:00
CSV.g4 got unbufferedchar working I think. 2012-09-30 12:37:35 -07:00
E.g fixed bug in [a-z] 2012-01-30 18:08:22 -08:00
ExtractInheritance.java tweak 2012-08-26 16:03:59 -07:00
Foo.java still has dfa and local predict ctx cache, but doesn't help much, and takes time. Eval preds as we pass them in full ctx mode; no sempred ctx in configs then. removed LANDMINE!!!!!!!!! some lame code that uses fields like _startIndex; fix that. added bail option to testjavalr. 18s to parse java.* with javalr full ctx now. 2012-07-25 18:47:34 -07:00
GenHierarchy.java tweak 2012-08-26 16:03:59 -07:00
HTMLParser.g got ambig pred thing working i think; unit tests. missing validating pred thing. 2011-11-28 19:16:45 -08:00

R.g4.graffle 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. 2011-12-29 17:04:40 -08:00

TestT.java playing with tests. 2012-09-24 08:54:32 -07:00
TestU.java fix a bug related to semantic predicates in the lexer and generally cleaned up variable and method names in the simulator. I moved all of the predicates to the right side of lexer rules in the unit tests. Later, we should ensure that predicates only occur on the right edge of lexer rules. We should state that the rule is not been accepted so we can't test things like getText(), we have to use more raw indexes into the character stream. In the lexer simulator, the addDFAState() method now does not try to compute whether there is a predicate in the configurations. That information has already been set into the ATNConfigSet by the getEpsilonTarget() method. [I should also point out that I have not tested the Java parsing in a while and now it hits a landmine on a number of common Java files in jdk :(. I'm not sure where that crept in] 2012-06-07 17:31:18 -07:00
