* PEP-0318, @decorator-style. In Guido's words:Anthony Baxter2004-08-021-1/+3
| | | | | "@ seems the syntax that everybody can hate equally" Implementation by Mark Russell, from SF #979728.
* SF patch #872326: Generator expression implementationRaymond Hettinger2004-05-191-2/+7
| | | | | | | | | | | | | | (Code contributed by Jiwon Seo.) The documentation portion of the patch is being re-worked and will be checked-in soon. Likewise, PEP 289 will be updated to reflect Guido's rationale for the design decisions on binding behavior (as described in in his patch comments and in discussions on python-dev). The test file, test_genexps.py, is written in doctest format and is meant to exercise all aspects of the the patch. Further additions are welcome from everyone. Please stress test this new feature as much as possible before the alpha release.

* Disambiguate the grammar for backtick.Guido van Rossum2002-05-241-1/+3
| | | | | | The old syntax suggested that a trailing comma was OK inside backticks, but in fact (due to ideosyncrasies of pgen) it was not. Fix the grammar to avoid the ambiguity. Fred: you may want to update the refman.
* John Aycock correctly pointed out that the grammar forTim Peters2002-05-231-1/+1
| | | | "power" was formally ambiguous. Here's his fix.
* Very subtle syntax change: in a list comprehension, the testlist inGuido van Rossum2001-10-151-1/+2
| | | | | | | | | | | | | | | "for <var> in <testlist> may no longer be a single test followed by a comma. This solves SF bug #431886. Note that if the testlist contains more than one test, a trailing comma is still allowed, for maximum backward compatibility; but this example is not: [(x, y) for x in range(10), for y in range(10)] ^ The fix involved creating a new nonterminal 'testlist_safe' whose definition doesn't allow the trailing comma if there's only one test: testlist_safe: test [(',' test)+ [',']]
* Implement PEP 238 in its (almost) full glory.Guido van Rossum2001-08-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This introduces: - A new operator // that means floor division (the kind of division where 1/2 is 0). - The "future division" statement ("from __future__ import division) which changes the meaning of the / operator to implement "true division" (where 1/2 is 0.5). - New overloadable operators __truediv__ and __floordiv__. - New slots in the PyNumberMethods struct for true and floor division, new abstract APIs for them, new opcodes, and so on. I emphasize that without the future division statement, the semantics of / will remain unchanged until Python 3.0. Not yet implemented are warnings (default off) when / is used with int or long arguments. This has been on display since 7/31 as SF patch #443474. Flames to /dev/null.
* Merging the gen-branch into the main line, at Guido's direction. Yay!Tim Peters2001-06-181-1/+2
| | | | | Bugfix candidate in inspect.py: it was referencing "self" outside of a method.

|
* Support for three-token characters (**=, >>=, <<=) which was written byThomas Wouters2000-08-241-3/+4
| | | | | Michael Hudson, and support in general for the augmented assignment syntax. The graminit.c patch is large!
* Added note stating that the parser module will need updating for mostFred Drake2000-08-231-0/+7

* PEP 214, Extended print Statement, has been accepted by the BDFL.Barry Warsaw2000-08-211-2/+2
| | | | | This change modifies Python's grammar to include the extended print form.
* Ignore Grammar/Makefile now that it's a made Makefile.Thomas Wouters2000-08-211-0/+1
|
* Apply SF patch #101135, adding 'import module as m' and 'from module importThomas Wouters2000-08-171-1/+3
| | | | | | | | name as n'. By doing some twists and turns, "as" is not a reserved word. There is a slight change in semantics for 'from module import name' (it will now honour the 'global' keyword) but only in cases that are explicitly undocumented.

* add dummy 'add2lib' target to Grammar/Makefile so non-GNU makes don't bail outTrent Mick2000-08-161-0/+3
| | | | | This closes patch: http://sourceforge.net/patch/index.php?func=detailpatch&patch_id=101176&group_id=5470

* added .cvsignore so cvs doesn't complain about the generated graminit.h andSkip Montanaro2000-07-271-0/+2

* slightly modified version of Greg Ewing's extended call syntax patchJeremy Hylton2000-03-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | executive summary: Instead of typing 'apply(f, args, kwargs)' you can type 'f(*arg, **kwargs)'. Some file-by-file details follow. Grammar/Grammar: simplify varargslist, replacing '*' '*' with '**' add * & ** options to arglist Include/opcode.h & Lib/dis.py: define three new opcodes CALL_FUNCTION_VAR CALL_FUNCTION_KW CALL_FUNCTION_VAR_KW Python/ceval.c: extend TypeError "keyword parameter redefined" message to include the name of the offending keyword reindent CALL_FUNCTION using four spaces add handling of sequences and dictionaries using extend calls fix function import_from to use PyErr_Format

| | | | | | | * dosmodule.c: MSDOS specific stuff from posixmodule.c. * posixmodule.c: removed all MSDOS specific stuff. * tokenizer.h, parsetok.h: in prototypes, don't mix named and unnamed parameters (MSC doesn't like this).
* change syntactical position of lambdef (was an atom, now is a test)Guido van Rossum1993-11-301-4/+2

* * import.c (get_module): pass .py filename to parse_file, not .pyc filename!Guido van Rossum1993-11-301-4/+8
| | | | | | | | | | | * funcobject.c (func_repr): don't call getstringvalue(None) for anonymous functions. * bltinmodule.c: removed lambda (which is now a built-in function); removed implied lambda for string arg to filter/map/reduce. * Grammar, graminit.[ch], compile.[ch]: replaced lambda as built-in function by lambda as grammar entity: instead of "lambda('x: x+1')" you write "lambda x: x+1". * Xtmodule.c (checkargdict): return 0, not NULL, for error.
* Committing the correct graminit.c; also changed confusing comments in Grammar.Guido van Rossum1993-10-271-2/+1
|
* * compile.[ch]: support for lambda()Guido van Rossum1993-10-261-3/+7
| | | | | | | | | | * PROTO.h, mymalloc.h: added #ifdefs for TURBOC and GNUC. * allobjects.h: added #include "rangeobject.h" * Grammar: added lambda_input; relaxed syntax for exec. * bltinmodule.c: added bagof, map, reduce, lambda, xrange. * tupleobject.[ch]: added resizetuple(). * rangeobject.[ch]: new object type to speed up range operations (not convinced this is needed!!!)

| | | | | | | * Grammar: add exec statement; allow testlist in expr statement. * ceval.c, compile.c, opcode.h: support exec statement; avoid optimizing locals when it is used * fileobject.{c,h}: add getfilename() internal function.
* * Lots of small changes related to access.Guido van Rossum1993-05-211-1/+1
| | | | | | | * Added "access *: ...", made access work for class methods. * Introduced subclass check: make sure that when calling ClassName.methodname(instance, ...), the instance is an instance of ClassName or of a subclass thereof (this might break some old code!)
* Several changes in one:Guido van Rossum1993-05-191-7/+13
| | | | | | | | | | | | | | | | (1) dictionaries/mappings now have attributes values() and items() as well as keys(); at the C level, use the new function mappinggetnext() to iterate over a dictionary. (2) "class C(): ..." is now illegal; you must write "class C: ...". (3) Class objects now know their own name (finally!); and minor improvements to the way how classes, functions and methods are represented as strings. (4) Added an "access" statement and semantics. (This is still experimental -- as long as you don't use the keyword 'access' nothing should be changed.)
