|
Initial Python3 target, branched from the Python target by Benjamin
|
Niemann, with lots of code cleanup and minor refactoring.
|
|
* CodeGenerator.java, Python3.stg:
|
Generated code now uses set notation for setTest, rather than long
|
conditionals like "a == FOO or a == BAR or 10 <= a <= 12". This is
|
a (slight) performance improvement.
|
|
* tokens.py:
|
Token objects no longer have get/set methods for their attributes as I
|
switched them to use @property instead. The attributes should be accessed
|
directly.
|
|
* tokens.py, Python3.stg:
|
Fix a circular dependency in generated parsers, and give Token objects the
|
ability to return their typeName when asked for it. (The generated
|
recognizer gives Token the mapping from token type to type name.)

|
|
* PythonTarget.java, dfa.py, exceptions.py, recognizer.py, streams.py:
|
ANTLRStringStream.LA() now returns the character's ordinal and
|
generated lexers operate on integers. Also made various performance
|
tunings.

|
|
* main.py, Python.stg (outputFile): Added simple __main__ section to
|
generated code, so (simple) grammars can be executed as standalone
|
script.
|
|
* tree.py (RecognitionException.extractInformationFromTreeNodeStream),
|
exceptions.py (CommonTree): Small bugfixes.
|
|

|
|
* recognizers.py (TokenSource): Added iterator interface to TokenSource
|
class - and thus to Lexer.
|
|
2007-06-27 Benjamin Niemann <pink@odahoda.de>
|
|
* Python.stg (genericParser, parser, treeParser): Use correct @init
|
action block for tree parsers.
|
|
2007-05-24 Benjamin Niemann <pink@odahoda.de>
|
|
* Python.stg (rule): Added support for @decorate {...} action for
|
parser rules to add decorators to the rule method.
|
|
2007-05-18 Benjamin Niemann <pink@odahoda.de>
|
|
* Python.stg (isolatedLookaheadRangeTest, lookaheadRangeTest):
|
Minor improvement of generated code (use '<lower> <= <LA> <= <upper>'
|
instead of '<LA> >= <lower> and <LA> <= <upper>').
