Change proposed terminology from context object to context specifier
2006-04-24 03:22:30 +00:00

Clarify the original meanings I intended for various terms, and record the fact that gaining consensus on the terminology is still an open issue

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.

More info on the __exit__ return issue, per Guido's request
2006-03-25 04:31:37 +00:00
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

Update this PEP to reflect the new design: exceptions are swallowed only
...
when __exit__ returns a true value.

Clarify the expanded code -- exc is just used as a flag.
2006-02-28 21:05:40 +00:00
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
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.
