kai zhu <[EMAIL PROTECTED]> added the comment: ported to python-2.6 & is a bit more stable (written a few py3k programs w/ it). the patches have been simplified & consolidated to a single file: ceval.c
u can also test out scripts generated by 2to3 by adding to them the magic line: "from __future__ import py3k_syntax" an example "python-2.6" script using "python-3.0" language syntax (& numpy if its installed) is provided @: http://www-rcf.usc.edu/~kaizhu/work/py3to2/current/example_py3k.py new features added by patch to python-2.6 (under py3k_syntax mode): pep3102 Keyword-Only Arguments pep3104 Access to Names in Outer Scopes pep3107 Function Annotations pep3111 Simple input built-in in Python 3000 pep3113 Removal of Tuple Parameter Unpacking pep3114 Renaming iterator.next() to iterator.__next__() pep3115 Metaclasses in Python 3000 pep3127 Integer Literal Support and Syntax - oct() functions differently in py3k_syntax mode pep3129 Class Decorators pep3132 Extended Iterable Unpacking pep3135 New Super misc exec becomes a function sans unicode & py3k's builtins module, the above (plus __future__) implements pretty much all of py3k's language syntax py3k_syntax mode: a special bitflag is embedded in codeobj->co_argcount, which triggers PyEval_EvalFrameEx to enable the backported opcodes (which r disabled by default) & use an alternate py3k __builtin__. codeobj->co_argcount now limited to range 0-0xffff with upper bits reserved for py3k flags codeobj->co_kwonlyargcount (limited to range 0-0xff) is embedded in upper bits of codeobj->co_argcount most of the trouble have been gettin kwonlyarg, annotations, & classes to work. there is one unrelated opcode (LOAD_ATTR_py3k) added to ceval.c for my personal use (curries attributes as a universal function), but can b safely disabled by commenting its case out of PyEvalFrameEx in ceval.c & deleting it from dict opnew_py2x in py3to2.py ---------- components: +Extension Modules, Library (Lib) -None Added file: http://bugs.python.org/file11842/README.txt _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3238> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
