Fred Drake 901a41e757 normalize markup for consistency 2003-07-01 16:17:50 +00:00
Barry Warsaw 6891cd3aa3 A few minor improvements 2003-06-28 15:22:16 +00:00
Jim Fulton 6c71091fbe Rewrote the docs for supporting cyclic garbage collection to reflect
the new way that once writes types.

Deleted the old section and sample code and added a new section
building on the Noddy example.

Jim Fulton db6a569de7 Changed the assignment of PyType_GenericNew to tp_new slot. Now do
this in module initialization before calling PyType_Ready.  (Sorry
Tim.) This is necessary to compile on cygwin.  AFAIK, we support
cygwin. If so, then we need to write extentions this way.

Fixed bug in implementation of tp_init function. It should be an int
function, not a PyObject *.

Raymond Hettinger 047c54bb24 Missing parenthesis. 2003-05-16 14:36:26 +00:00
Jim Fulton a24d73ddb1 Added a missing PyObject* cast to the dealloc examples.
Added a note that the mechanism for defining new tyoes documented here
only works for Python 2.2 and higher.

Jim Fulton aea763bde7 Removed reference to the out-of-date (and not very useful)
Objects/xxobject.c example.

Updated the discussion of type checking to refer to
PyObject_TypeCheck.

Jim Fulton 3ff5bb20b7 Fixed small typo Pointed out by Michael Hudson. 2003-05-08 10:35:07 +00:00
Jim Fulton 83cedcf660 Fixed a typo in an example dealloc routine that calls it's "self"
argument "obj" rather than "self".
2003-05-08 10:32:10 +00:00
Jim Fulton aed0a4a138 Rewrote the basic section of the chapter on defining new types.
Changed the example to show how to create types the new way:

- Use a class new method rather than a new function.

- Use self->ob_type->tp_free in deallocators

- Use attribute descriptors rather than set/getattr methods.

- Make the type usable as a base type.

I split the example into 3 parts:

1. The minimal new type

2. Adding attributes and methods.

3. Finer control over attributes.

It's much simpler to define builtin types. These updates hopefully
show this.

I also made minor wording changes in two other places.

I still need to update xxobject.c

Typo fix.

Fred Drake a3cd9bbaa3 Remove now-obsolete staticforward/statichere discussion. 2002-07-17 16:40:39 +00:00
Fred Drake 9aa97e835d Minor wording changes, plus correct a typo. 2002-05-14 22:02:07 +00:00
Fred Drake 292da58a5c Change the type of the tp_dealloc back to what it really is.
Change a section title to fit in better.
2002-04-12 18:28:08 +00:00
Fred Drake 0babc44ab2 Update the type of tp_dealloc. 2002-04-12 15:37:43 +00:00
Fred Drake 68304ccce3 Move reference material on PyArg_Parse*() out of the Extending & Embedding
document to the C API reference.  Move some instructional text from the API
reference to the Extending & Embedding manual.

Fix the descriptions of the es and es# formats for PyArg_Parse*().
This closes SF bug #536516.
2002-04-05 23:01:14 +00:00
Fred Drake 103b548a76 Add a note warning against semicolons following PyObject_HEAD.
Minor cleanups.
2002-04-02 15:42:46 +00:00
Fred Drake 0ffd14c9ea Started updating information about defining attributes on types.
There's still a long way to go, but we're starting to see some real
content in the docs.
2002-03-29 22:45:28 +00:00
Fred Drake 0f9a34da2c Added comments for more entries of the type structure in the example
type implementation.
2002-03-28 23:45:22 +00:00
Fred Drake 81b750d467 Move some of the longer example code to external fragments, and
include them using \verbatiminput.  This has the advantage that pages
can still break at reasonable places, and examples that go longer than
a page won't get cut off.

Make a few small markup adjustments for consistency.

Explain that PyObject_New() is not a C function but a polymorphic
beast that returns a pointer to the type that's passed as the first
arg.

Explain why type objects use the PyObject_VAR_HEAD.

Fred Drake 5d117472b4 Describe how to support the iterator protocol in extension types.
This closes SF bug #420851.

Michael W. Hudson 8fbd4a3e78 That hasn't been my email address for a while! 2002-01-16 14:55:05 +00:00
Fred Drake 145b479508 Added discussion of protecting against screwing up the exception state in
an object's deallocator, including an example of how to do this.
2001-12-11 19:28:22 +00:00
Fred Drake ef6373a4f6 Exhibit good form in C code: always provide docstrings in method tables, and
always fill in all slots of table entries.
Fixed a few minor markup errors.
2001-11-17 06:50:42 +00:00
Guido van Rossum 7a59445e37 Document required return values -1, 0, 1 for tp_compare handler, as
suggested in SF patch #424475.  Also document exception return.

Fred Drake 3ab0ac7cd4 Remove comment that no longer applies. 2001-09-26 22:26:45 +00:00
Barry Warsaw da21ce3e31 On Fred's suggestion, convert sprintf() examples to use
PyString_FromFormat().  Also fixed one grammar problem, and a few
other mark-up issues.  Sample code not checked.
