1 2012-06-26 Benjamin S Wolf <jokeserver+antlr3 (a] gmail.com> 2 3 Initial Python3 target, branched from the Python target by Benjamin 4 Niemann, with lots of code cleanup and minor refactoring. 5 6 * CodeGenerator.java, Python3.stg: 7 Generated code now uses set notation for setTest, rather than long 8 conditionals like "a == FOO or a == BAR or 10 <= a <= 12". This is 9 a (slight) performance improvement. 10 11 * tokens.py: 12 Token objects no longer have get/set methods for their attributes as I 13 switched them to use @property instead. The attributes should be accessed 14 directly. 15 16 * tokens.py, Python3.stg: 17 Fix a circular dependency in generated parsers, and give Token objects the 18 ability to return their typeName when asked for it. (The generated 19 recognizer gives Token the mapping from token type to type name.) 20 21 2007-11-03 Benjamin Niemann <pink (a] odahoda.de> 22 23 * PythonTarget.java, dfa.py, exceptions.py, recognizer.py, streams.py: 24 ANTLRStringStream.LA() now returns the character's ordinal and 25 generated lexers operate on integers. Also made various performance 26 tunings. 27 28 2007-10-07 Benjamin Niemann <pink (a] odahoda.de> 29 30 * main.py, Python.stg (outputFile): Added simple __main__ section to 31 generated code, so (simple) grammars can be executed as standalone 32 script. 33 34 * tree.py (RecognitionException.extractInformationFromTreeNodeStream), 35 exceptions.py (CommonTree): Small bugfixes. 36 37 2007-09-30 Benjamin Niemann <pink (a] odahoda.de> 38 39 * recognizers.py (TokenSource): Added iterator interface to TokenSource 40 class - and thus to Lexer. 41 42 2007-06-27 Benjamin Niemann <pink (a] odahoda.de> 43 44 * Python.stg (genericParser, parser, treeParser): Use correct @init 45 action block for tree parsers. 46 47 2007-05-24 Benjamin Niemann <pink (a] odahoda.de> 48 49 * Python.stg (rule): Added support for @decorate {...} action for 50 parser rules to add decorators to the rule method. 51 52 2007-05-18 Benjamin Niemann <pink (a] odahoda.de> 53 54 * Python.stg (isolatedLookaheadRangeTest, lookaheadRangeTest): 55 Minor improvement of generated code (use '<lower> <= <LA> <= <upper>' 56 instead of '<LA> >= <lower> and <LA> <= <upper>'). 57 58 59
