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
The attached patch set includes a workaround to get Python with
Unicode compile on BSDI 4.x (courtesy Thomas Wouters; the cause
is a bug in the BSDI wchar.h header file) and Python interfaces
for the MBCS codec donated by Mark Hammond.
Also included are some minor corrections w/r to the docs of
the new "es" and "es#" parser markers (use PyMem_Free() instead
of free(); thanks to Mark Hammond for finding these).
The unicodedata tests are now in a separate file
(test_unicodedata.py) to avoid problems if the module cannot
be found.
Attached you find the latest update of the Unicode implementation.
The patch is against the current CVS version.
It includes the fix I posted yesterday for the core dump problem
in codecs.c (was introduced by my previous patch set -- sorry),
adds more tests for the codecs and two new parser markers
"es" and "es#".
Attached you find an update of the Unicode implementation.
The patch is against the current CVS version. I would appreciate
if someone with CVS checkin permissions could check the changes
in.
The patch contains all bugs and patches sent this week and also
fixes a leak in the codecs code and a bug in the free list code
for Unicode objects (which only shows up when compiling Python
with Py_DEBUG; thanks to MarkH for spotting this one).
(python): Set defgroup :prefix to "py-" to make variable names cleaner.
(py-jpython-command, py-jpython-command-args): Set :tag for proper
capitalization of JPython in variable name display.
first time a py buffer is visited during the Emacs session. This
ensures that py-which-shells is initialized and also guarantees that
the mode lines reflect the correct shell. First bug found by GvR,
second one has long bugged :) me.
(py-toggle-shells): Programmatically, arg can also take the symbols
`cpython' or `jpython', which makes it easy to call with the value of
py-default-interpreter.
(py-shell): Don't need to initialize py-which-* variables since these
will guarantee to be initialized by python-mode when the first py
buffer is visited.
(py-default-interpreter): Update docstring.
casing when py-honor-comment-indentation is nil, but this could be a
religious issue with some. Seems to me we should still be dedenting
such comment lines one level.
buffer-syntactic-context -- just short circuit the TQS test by jumping
to point-min and doing the test from there. For long files, this will
be faster than looping with a re-search-backwards.
I don't know what its origins are but I think I've seen it
once in a NeXT dictionary application -- not sure whether
anyone owns copyright but I don't see why we should risk it.
py-newline-and-indent. These ought to get picked up by the mapcar
that follows; any existing binding to newline-and-indent gets shadowed
to py-newline-and-indent.
This will break some people who, e.g. bind C-m or C-j to newline but
still want these bound to py-newline-and-indent in Python mode. On
the other hand, the forced binding pisses off Emacs diehards. So
consider this experimental and see if any tall Dutch guys complain :-)
standard narrow-to-defun but works with Python classes and methods.
With no arg, narrows to most enclosing def/method. With C-u arg,
narrows to most enclosing class.
string we find ourselves in, based on the passed in delimiter.
(py-compute-indentation): Fixes for indentation errors when we land
inside a triple quoted string. For example:
def foo():
if os.path.isfile(o_pri_mbox_file) and os.path.isfile(o_pub_mbox_file):
print """\
I found both a private and a public mbox archive file
private: %s
public : %s
I won't move either file, but you should choose one and move it to
%s
You may want to merge them manually, but be careful about exposing private
correspondences to the public.""" % (
o_pri_mbox_file, o_pub_mbox_file, mbox_file)
*----indentation would be wrong on this line.
#simple things. First step: rename the Imenu supportive variables and
#functions in this file to py-imenu-* so I can grok what is part of
#python-mode and what is part of Imenu.
(py-imenu-create-index-engine): Fixed problem with two classes in a
single file, caused by new semantics of py-beginning-of-def-or-class
when called programmatically.
#Note, there are still some problems with Imenu when arguments to
#functions are funky, but it should be much better now.
string in the argument to execfile() so a Windows temp directory
named, e.g. c:\\tmp doesn't get interpreted as a file name with an
embedded tab! (given by C. Waldman).
this string should not end with whitespace.
(py-compute-indentation): Append whitespace regexp to
py-block-comment-prefix so that any combination of intervening
whitespace will be recognized.
change error messages to be a little more straightforward
change definition of FULL_PATH so that an error is raised if the
setuid wrapper is used un-edited
shell buffers.
(py-shell): Moved the require of comint to the top level. Also
use-local-map py-shell-map instead of hacking on the comint-mode-map.
This eliminates breakage of other comint-mode buffers (e.g. shell).
interactions with newer Emacsen, I've rewritten the way all the
process filters work in the *Python* buffer. We use more of the
comint infrastructure, specifically the default process filter. This
means that scrolling is now handled by the default comint variables
including comint-scroll-to-bottom-on-output. Note that this is
somewhat experimental change!
(py-comint-output-filter-function): Moved to here from the obsolete
py-process-filter function, the logic to pop and exec the next queued
file waiting to be executed.
(py-execute-file): Don't bind comint-scroll-to-bottom-on-output to t,
and save the excursion when inserting the "working on" message. This
lets the standard comint scrolling variables as set by the user,
continue to work.
(python-mode, py-shell, py-describe-mode): Remove description of
py-scroll-process-buffer. Also in py-shell, make
comint-output-filter-functions buffer-local, and add
py-comint-output-filter-function to this hook (instead of setting the
process filter).
(py-scroll-process-buffer): Deleted this variable. See comint
variables including comint-scroll-to-bottom-on-output.
(py-execute-region): When exec files are being queued, push the next
temp file on the end of the list.
(py-submit-bug-report): Removed reporting of py-scroll-process-buffer.
"3.67 fixes Imenu as far as classes are concerned, but some default
values for function arguments are still not supported."
This ought to fix that problem.
indetnation of normal statements: The regular expression that searches
for indenting comment lines has been changed to not require a
space/tab after the first `#'. We then explicitly look for
py-block-comment-prefix depending on the value of
py-honor-comment-indentation.
I think this more accurately reflects the documentation for
py-honor-comment-indentation.
conformations, etc., etc. inspired and given by Michael Ernst. These
include error string fixes, moving of comments to docstrings, some
other non-related typos, terminology standardizing (b/w TP and myself,
and b/w myself and myself :-) although more can still be done.
E.g. "outdenting" => "dedenting".
serial number isn't enough to uniquify the temp file name -- what if
two users are on the same machine? Add in the (emacs-pid) to help
further. Should never be tickled on Emacs 20, XEmacs 20, 21.
py-mark-def-or-class): Integrated Michael Ernst latest patches.
Primarily, it allows functions that search or mark defs/classes based
on programmatic specification, to take an 'either flag value which
allows searching for both classes and defs (stopping at the nearest
construct).
Also clean up some docstrings.
comment-indent-function's default lambda value (in simple.el), this
version finally kills this nit: auto-filling a comment that starts in
column zero with filladapt turned off would cascade the #'s to the
right.
Now auto-filling seems to work with or without filladapt, and with the
comment starting in any column.
(python-mode): Set comment-indent-function.
