Georg Brandl 8a1e5adb10 #11248: look up special methods on type. 2011-03-20 21:51:37 +00:00
Nick Coghlan 12bfa7c87f The PEP 343 implementation for the beta releases seems to have met with general approval (PEP 0 has actually been showing 343 as being Final for ages) 2006-07-30 12:19:23 +00:00
Nick Coghlan 10535b0182 Address some comments from Guido by cutting back on the overengineering in the terminology section. Also a few minor grammar cleanups and fixes I missed last night. 2006-05-03 09:41:53 +00:00
David Goodger e4f531296c changed encoding to UTF-8; added emacs stanza 2006-05-02 18:01:35 +00:00
Nick Coghlan 15948f5fe0 Remove the __context__ method from PEP 343, and update the terminology section (again). Record a couple of remaining open issues, and try to clarify the resolved issues sections by only giving a very brief overview of all the rejected options that aren't relevant any more. 2006-05-02 14:28:47 +00:00
Nick Coghlan c854ad6eb9 Correct a bug in the nested() example 2006-04-24 04:41:45 +00:00
Nick Coghlan d36c583656 Change proposed terminology from context object to context specifier 2006-04-24 03:22:30 +00:00
Nick Coghlan db32145d0e Clarify the original meanings I intended for various terms, and record the fact that gaining consensus on the terminology is still an open issue 2006-04-23 05:14:10 +00:00
Phillip J. Eby 453a6c7d77 Make "context" vs. "context manager" terminology consistent.
Originally, there were only context managers, so a lot of text referred
to context managers that now should refer to contexts since the
__context__ method was added.  All contexts are context managers, so
these references were technically correct in some sense, but are
easier to understand if the more-specific terms are used.

Phillip J. Eby 47e612f17c More info on the __exit__ return issue, per Guido's request 2006-03-25 04:31:37 +00:00
Phillip J. Eby 0d09dd2a6a Document the difference between a normal return from __exit__() and an
exception return.  Fix a problem with @contextmanager not detecting
a broken generator that yields after a throw().  Make @contextmanager
not reraise exceptions, but return a false value in that case instead.
2006-03-25 00:26:26 +00:00
Guido van Rossum f6659b5348 Update this PEP to reflect the new design: exceptions are swallowed only
when __exit__ returns a true value.

Neal Norwitz afdd996d22 Minor detail about the warning 2006-02-28 21:13:18 +00:00
Guido van Rossum d8e895c878 Clarify the expanded code -- exc is just used as a flag. 2006-02-28 21:05:40 +00:00
Guido van Rossum f038797f00 Change the PEP to add that __exit__() must re-raise the exception
passed in, if any.  This appears to be a deviation from how the PEP
was originally seen; but I think it's essential to be able to make a
simple promise about generators decorated with @contextmanager.

Added the transition plan and the __future__ statement.

Also some miscellaneous cleanup.
2006-02-28 20:58:17 +00:00
Guido van Rossum 53c1f1795e Change the translation slightly.
ctx.__exit__ is now bound before ctx.__enter__;
ctx.__enter__ is still called before the try-block
is entered, but VAR is assigned *inside* the try-block.
Clarify what happens to break, continue, return.
2006-02-27 21:08:43 +00:00

Guido van Rossum a61abd2828 Restrict 'as VAR' to VAR being a single variable or a parenthesized
series of variables.  This keeps the door open for a future extension
with multiple as-clauses.
