Sam Harwell e5d7c27b09 Updated comments to indicate preference of .g4 over .g 2012-03-30 11:37:22 -05:00
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

Sam Harwell 3f1f76df7d Move reportAmbiguity, reportContextSensitivity, reportAttemptingFullContext, reportInsufficientPredicates from ANTLRErrorStrategy to ANTLRErrorListener. 
Add BaseErrorListener to allow implementing ANTLRErrorListener without implementing every method (e.g. ConsoleErrorListener).
DiagnosticErrorStrategy is now DiagnosticErrorListener, updated tests.

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
Terence Parr 642177f716 forgot to add dispatch methods in context objects. in-parse listeners should work now. 2012-02-19 11:25:15 -08:00
Terence Parr 4e8931519c added -parse-listener option and generated code if option on. parse listener differs from tree listener 2012-02-18 16:49:05 -08:00
Terence Parr 71b75c88dd Fix regression; did not gen enter/exit in alt label structs. 2012-02-18 15:16:42 -08:00
Terence Parr c6fd897287 altered naming scheme for listeners/visitors 
* names changed. visit() -> visitX(). enter/exit() -> enter/exitX()
* capitalizing automatically now. rule s -> SContext not sContext
* no enter/exit method in generic rule context object if rule has alt labels, nor in interfaces.
* dup labels allowed in same rule
* label X or x illegal if rule x exists

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.
