Martin v. Löwis ab2f8f7bd5 __hash__ may now return long int; the final hash
value is obtained by invoking hash on the long int.

George Yoshida 8f505aed46 Duplicated description about the illegal continue usage can be found in nearly the same place.
They are same, so keep the original one and remove the later-added one.

Nick Coghlan afd5e63e24 Finish bringing SVN into line with latest version of PEP 343 by getting rid of all remaining references to context objects that I could find. Without a __context__() method context objects no longer exist. Also get test_with working again, and adopt a suggestion from Neal for decimal.Context.get_manager() 2006-05-03 13:02:47 +00:00

Fred Drake f25fa6ddb9 avoid ugly markup based on the unfortunate conversions of ">>" and "<<" to
guillemets; no need for magic here

Guido van Rossum da5b701aee Get rid of __context__, per the latest changes to PEP 343 and python-dev
discussion.
There are two places of documentation that still mention __context__:
Doc/lib/libstdtypes.tex -- I wasn't quite sure how to rewrite that without
spending a whole lot of time thinking about it; and whatsnew, which Andrew
usually likes to change himself.

Georg Brandl 3c1983face Patch #1479438: add \keyword markup for "with". 2006-04-30 19:34:19 +00:00
Nick Coghlan a7e820a408 Move the PEP 343 documentation and implementation closer to the
terminology in the alpha 1 documentation.

 - "context manager" reverts to its alpha 1 definition
 - the term "context specifier" goes away entirely
 - contextlib.GeneratorContextManager is renamed GeneratorContext

There are still a number of changes relative to alpha 1:

  - the expression in the with statement is explicitly called the
    "context expression" in the language reference
  - the terms 'with statement context', 'context object' or 'with
    statement context' are used in several places instead of a bare
    'context'. The aim of this is to avoid ambiguity in relation to the
    runtime context set up when the block is executed, and the context
    objects that already exist in various application domains (such as
    decimal.Context)
  - contextlib.contextmanager is renamed to contextfactory
    This best reflects the nature of the function resulting from the
    use of that decorator
  - decimal.ContextManager is renamed to WithStatementContext
    Simple dropping the 'Manager' part wasn't possible due to the
    fact that decimal.Context already exists and means something
    different. WithStatementContext is ugly but workable.

A technically unrelated change snuck into this commit:
contextlib.closing now avoids the overhead of creating a
generator, since it's trivial to implement that particular
context manager directly.

Guido van Rossum 38fff8c4e4 Checking in the code for PEP 357.
This was mostly written by Travis Oliphant.
I've inspected it all; Neal Norwitz and MvL have also looked at it
(in an earlier incarnation).
2006-03-07 18:50:55 +00:00
Guido van Rossum c2e20744b2 PEP 343 -- the with-statement.
This was started by Mike Bland and completed by Guido
(with help from Neal).

This still needs a __future__ statement added;
Thomas is working on Michael's patch for that aspect.

There's a small amount of code cleanup and refactoring
in ast.c, compile.c and ceval.c (I fixed the lltrace
behavior when EXT_POP is used -- however I had to make
lltrace a static global).

Neal Norwitz f9f61b4aa2 Note version added for conditional expressions 2006-02-27 16:31:12 +00:00
Thomas Wouters dca3b9c797 PEP 308 implementation, including minor refdocs and some testcases. It
breaks the parser module, because it adds the if/else construct as well as
two new grammar rules for backward compatibility. If no one else fixes
parsermodule, I guess I'll go ahead and fix it later this week.

The TeX code was checked with texcheck.py, but not rendered. There is
actually a slight incompatibility:

>>> (x for x in lambda:0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: iteration over non-sequence

changes into

>>> (x for x in lambda: 0)
  File "<stdin>", line 1
    (x for x in lambda: 0)
                     ^
SyntaxError: invalid syntax

Since there's no way the former version can be useful, it's probably a
bugfix ;)

Armin Rigo ddddd2f7e6 Updating the short blob about old/new-style classes to reflect (IMHO) more
precisely the motivation and the differences.

Added links to www.python.org/doc/newstyle.html and a footnote to warn against
the statement "x[i] is equivalent to x.__getitem__(i)", which already caused
many invalid bug reports on SF.
