Neal Norwitz aa38aa5435 SF #515009, delete global variable that was apparently used only
in a for loop.

Jeremy Hylton 96d68d57be Add opcodes for floor division and true division (PEP 238) 2001-08-29 18:02:21 +00:00
Jeremy Hylton 318e167e98 FOR_ITER is a jrel_op() not a plain old def_op() 2001-08-28 15:32:48 +00:00
Tim Peters 5ca576ed0a Merging the gen-branch into the main line, at Guido's direction. Yay!
Bugfix candidate in inspect.py:  it was referencing "self" outside of
a method.

Guido van Rossum 59d1d2b434 Iterators phase 1. This comprises:
new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER
new C API PyObject_GetIter(), calls tp_iter
new builtin iter(), with two forms: iter(obj), and iter(function, sentinel)
new internal object types iterobject and calliterobject
new exception StopIteration
new opcodes for "for" loops, GET_ITER and FOR_ITER (also supported by dis.py)
new magic number for .pyc files
new special method for instances: __iter__() returns an iterator
iteration over dictionaries: "for x in dict" iterates over the keys
iteration over files: "for x in file" iterates over lines

TODO:

documentation
test suite
decide whether to use a different way to spell iter(function, sentinal)
decide whether "for key in dict" is a good idea
use iterators in map/filter/reduce, min/max, and elsewhere (in/not in?)
speed tuning (make next() a slot tp_next???)

Jeremy Hylton a39414b15c PEP 227 implementation
Track changes to new opcodes.  Add hasfree list that applies to all
ops that use the closure.

Skip Montanaro e99d5ea25b added __all__ lists to a number of Python modules
added test script and expected output file as well
this closes patch 103297.
__all__ attributes will be added to other modules without first submitting
a patch, just adding the necessary line to the test script to verify
more-or-less correct implementation.

Guido van Rossum fc53c13dd5 Checking in a slight variation of Barry's patch 103303. 2001-01-19 02:41:41 +00:00

Thomas Wouters 6af3b37021 Add missing opcodes. Thanx to jeremy for reminding me ;) 2000-08-24 22:44:53 +00:00
Thomas Wouters 104a7bcc28 Support for augmented assignment in the UserList, UserDict, UserString and
rfc822 (Addresslist) modules. Also a preliminary testcase for augmented
assignment, which should actually be merged with the test_class testcase I
added last week.

Fred Drake ef8ace3a6f Charles G. Waldman <cgw@fnal.gov>:
Add the EXTENDED_ARG opcode to the virtual machine, allowing 32-bit
arguments to opcodes instead of being forced to stick to the 16-bit
limit.  This is especially useful for machine-generated code, which
can be too long for the SET_LINENO parameter to fit into 16 bits.

This closes the implementation portion of SourceForge patch #100893.

Barry Warsaw 203da6dfe4 Add the new PRINT_ITEM_TO and PRINT_NEWLINE_TO opcodes. 2000-08-21 17:18:40 +00:00
Thomas Wouters 5215225ea1 Apply SF patch #101135, adding 'import module as m' and 'from module import
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.

Thomas Wouters 0be5aab04d Merge UNPACK_LIST and UNPACK_TUPLE into a single UNPACK_SEQUENCE, since they
did the same anyway.

I'm not sure what to do with Tools/compiler/compiler/* -- that isn't part of
distutils, is it ? Should it try to be compatible with old bytecode version ?

Guido van Rossum d30dedca27 Michael Hudson: With the (cool!) new call syntax, the longest opcode
name is much longer, which fouls up dis's formatting slightly; this is
a "fix" for that.
2000-03-30 15:02:11 +00:00
Jeremy Hylton 7690151c7e slightly modified version of Greg Ewing's extended call syntax patch
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

Guido van Rossum 00f86e6086 Of course, when the type of the argument to dis() is unsupported, it
should raise TypeError, not ValueError...
1997-01-17 20:08:18 +00:00
Guido van Rossum bd30795192 More user friedly interface:
dis() still disassembles the last frame of the lats stack trace.

dis(x) disassembles x, which may be a code object, function, or method.

disassemble(co, [lasti]) disassembles a code object; the lasti
argument is now optional.

disco(...) is an alias for disassemble(...), for backward compatibility.
