sinopsysHK 58ef6bbc96 Enable running debug mode of ParserATNSimulator 
This is to have appropriate logs during debug and avoid crashing in some occasions when startIndex=stopIndex

range(startIndex, stopIndex) is equivalent to an array of values from startIndex to stopIndex-1 thus when startIndex=stopIndex range(startIndex, stopIndex+1) = [startIndex] which is not exactly an interval and would break getText that is expecting an interval as a Tuple.

Python: add public getter to parsers to access syntax error count.

Robert Jacobson 8f30ae6610 Import RuleContext into the antlr4 module namespace. See Issue #2012. 2017-09-16 16:16:01 -04:00
Renata Hodovan 6e02088e6a Python: add public getter to parsers to access syntax error count. 
ANTLR parsers in Java are allowed to access the number of encountered
syntax errors via the getNumberOfSyntaxErrors method. However, the
Python variants must use the protected _syntaxErrors member to get this
value. The patch defines the same getter for Python targets too.

Terence Parr b57843d983 Merge pull request #1546 from sharwell/fix-1545 
Fix multiple problems with optional block bypass at end of rule
 2016-12-27 21:47:12 -08:00
Sam Harwell 24b20e236f Remove redundant isExpectedToken check 
We know by the time this check was reached that neither EPSILON nor the LL(1)
symbol are in the lookahead set from the current state. Since EPSILON is not
included, the state cannot see to the end of the rule and thus nextTokens
contains the complete set of valid LL(1) symbols from the current state. It is
therefore impossible for the LL(1) symbol to be "expected" when considering
lookahead with full context.

Sam Harwell 8b21cc3dfb Fix DefaultErrorStrategy.sync handling of end of rule 
This change updates the default sync() strategy to match the strategy used
for selecting an alternative when prediction leaves the decision rule prior
to reaching a syntax error.

Closes #1545

Renata Hodovan bd09023209 Call visitErrorNodes properly in Python targets. 
The consume method of the Parser class calls visitTerminal on both
TerminalNodes and ErrorNodes even if the comment above states that
ErrorNodes should be visited by visitErrorNodes. This behaviour
is also inconsitent with the Java target. The patch fixes this in
both Python targets.
