Terence Parr bf9c7c3a28 Remove old TokenRewriteStream in favor of new TokenStreamRewriter that is not a stream; it feeds off of the stream to provide transformations of that original stream. Updated the comment at the top of the file. Instead of toString() we use getText(). Altered the unit tests to create a buffered stream and then create the rewriter attached to that. 2012-04-02 18:10:32 -07:00
Terence Parr 3849cd572d rm SymbolStream<T>, change all to TokenStream. all but 5 tests pass. 2012-04-02 16:49:04 -07:00
Sam Harwell 53c5aecb85 Implement UnbufferedTokenStream.get(int) within marked intervals 2012-04-01 18:23:32 -05:00

Terence Parr e1870d16e9 added convenience getText(ctx) method to TokenStream. unlikley to need in CharStream and can get another way 2012-04-01 12:23:45 -07:00
Terence Parr 588e30bfe1 getText(...) moved to CharStream and TokenStream; cleaned up names. removed getInputString from parser. 2012-04-01 12:12:49 -07:00
Terence Parr f238d7579e added getText() to ParseTree. getText(tokens) is still really what you want but convenient for ctx.type().getText() when it's just one token. 2012-03-31 17:27:11 -07:00
Terence Parr cc20a52cdd allow special "tokens" start rule name so we can test pure lexer grammars. 2012-03-31 15:54:00 -07:00

Terence Parr 542e700644 fix antlr/antlr4/#48 (getText from parse tree node). Don't NPE when start/stop null in getSourceInterval. 2012-03-25 10:01:27 -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.
 2012-03-12 15:07:48 -05:00
Sam Harwell 768bfc0cf2 Add ProxyErrorListener to allow dispatching error reporting to multiple listeners without manually iterating over the list of listeners. 2012-03-12 15:07:48 -05:00
Sam Harwell dce72dcbfb * Recognizer._listeners initialized to have a single ConsoleErrorListener 
* Use CopyOnWriteArrayList so listeners can be added/removed in callbacks
* Remove special handling for _listeners null or empty (never null, ConsoleErrorListener will be present if feature is desired)
 2012-03-12 15:01:21 -05:00
Sam Harwell 50180825d9 Add boolean field ParserATNSimulator.reportAmbiguities (default true). When false, ambiguous alts aren't reported which allows usage of (the faster) incomplete semantic predicate evaluation even within execATN. 2012-03-10 16:41:57 -06:00
Sam Harwell 04cd48e88d No need to fully evaluate predicates when called from execDFA because ambiguous alts aren't reported anyway. 2012-03-10 16:32:10 -06:00
Sam Harwell 2cc39c2f9b Evaluate predicates for all ambiguous alternatives and report if still ambiguous after predicate evaluation. Remove misleading message insufficient predicates. Fixes antlr/antlr4#31. Partially addresses antlr/antlr4#39. 2012-03-10 16:16:39 -06:00
