The main incompatibility is that the error reporting method is now
called as
parser.syntax_error(msg)
instead of
parser.syntax_error(lineno, msg)
This new version also has some code to deal with the <?xml?> and
<!DOCTYPE> tags at the start of an XML document.
The documentation has been updated, and a small test module has been
created.
Here's my suggested replacement for gzip.py for 1.5.1. I've
re-implemeted methods readline and readlines, added an _unread, and
tweaked read and _read.
I tried a more complicated buffer scheme for unread (using a list of
strings and string.join), but it was more complicated and slower.
This version is a lot faster than the current version and is still
pretty simple.
Fixed problems when unpickling in restricted execution environments.
These methods try to assign to an instance's __class__ attribute, or
access the instances __dict__, which are prohibited in REE. For the
first two methods, I re-implemented the old behavior when assignment
to value.__class__ fails.
For the load_build() I also re-implemented the old behavior when
inst.__dict__.update() fails but this means that unpickling in REE is
semantically different than unpickling in unrestricted mode.
Removed " (byte code instruction)" from the output of the {opcodedesc}
environment; this should only appear in the index (which it now does).
Removed some really old cruft related to otherwise removed debugging code.
(I *think* assignments to $* set & clear auto-flush of <STDOUT>, but don't
really remember. Removing them seems to not change anything!)
semantic concepts.
Added two new ones (not discussed with Guido:
\constant{}: Markup for constants defined in Python modules.
\cfunction{}: Markup for C functions; these should probably be distinguished
by font, but are not at this time (since they're typically \code{} at
this point).
continuation lines. This fixes this bug report, reported by Frank
Stajano.
# But if I split the "raise" line and reindent, the else WRONGLY goes up a
# level (?!?)
while condition1:
if condition2:
raise error3, \
moreInfo4
else: # meant to close "if condition2"
action5()
a religious issue: RMS decrees that the Enter (RET) key should just do
a newline and a LFD (C-j) should do a newline and indent (i.e. the
python-mode version of this). Almost everyone I know disagrees and
finds that RET should do newline and indent. Almost everyone hacks
their modes to do this, if they know how. Because it's hard for
newbies to figure out how to do this, and because most DOS keyboards
lack a LFD (leaving users to the more obscure C-j), I think it makes
better sense to add this default binding.
Guido, you should probably look at this. The pickle documentation is out of
date; I don't see anything about the __reduce__() stuff or the
__safe_for_unpickling__ attribute.
is based on the line above, watch out for landing inside a triple
quoted string. In this case, use iterative search +
parse-partial-sexp backwards to find the beginning of the string.
Note this does affect performance, but very little in the common cases
(I hope). It could be made *much* faster by adding Emacs and XEmacs
dependent code -- different code naturally. :-(
Fixes the following reported bug:
if len(sys.argv) >= 6:
# More lines here
fptr = open('/etc/hosts', 'w')
fptr.write("""# /etc/hosts -- autocreated by /etc/ppp/ip-up

# Address from pppd

""" % (ipaddr, ipname) )
os.chmod('/etc/hosts', 0644)
file local variable section of a file. When set, and the user hits
C-c C-c, this file gets executed instead of the buffer's file. Idea
given by Roy Dragseth <royd@math.uit.no>, but implemented differently.
(py-execute-buffer): Support py-master-file variable. If this names a
relative path, default-directory is prepended via expand-file-name.
These are intended to support semantic markup. There are a number
of places in the documentation where the exact meaning of an
indentifier marked \code{} in the running text is ambiguous (could
be a module or a class, a function or a method, etc.). These are
intended to clarify the intent of the identifier for processing
applications and more intelligent style processing.
