1. use dict.get instead of try/except KeyError
2. if the url scheme is 'http' then avoid the series of
'if var in [someseq]:'. instead, inline all of the code.
3. find = string.find
1) I added a command queue which is helpful to me (at least so far) and
would also allow syntax like 's;s' (step; step) in conjunction with precmd
2) doc_leader allows the derived class to print a message before the help
output. Defaults to current practise of a blank line
3) nohelp allows one to override the 'No help on' message. I need
'Undefined command: "%s". Try "help".'
4) Pass line to self.precmd to allow one to do some parsing: change first
word to lower case, strip out a leading number, whatever.
5) Pass the result of onecmd and the input line to postcmd. This allows
one to ponder the stop result before it is effective.
6) emptyline() requires a if self.lastcmd: conditional because if the
first command is null (<cr>), you get an infinite recursion with the
code as it stands.
by the new '-x' arguments, losing the previous items. Thus,
test_support, test_b1 & test_b2 are executed (and warnings issued).
(Discovered by Vladimir Marangozov.)
instead of a list, turn it into a list containing that string. This
avoids an apparently common newbie mistake -- passing in a single
string for the destination and have it treated as a sequence of
characters.
displays funny characters, like spaces or control characters, more
clearly (one of my pet peeves in error messages). Also only suppress
the filename if it is None; display it if it is '', since that would
be a genuine (illegal) filename passed in!
how to exit (in a platform dependent way!). We use os.sep to
determine which platform we're on, since I expect that this will work
better for minority platforms.

the "initialcolor" code is broken in several places in the
current version of tkColorChooser. I've attached an up-
dated version for 1.5.2.
DOS (as well as OS/2). I presume that making a call to putenv() with
a lowercase key will actually do the right thing. I know this is so
on Windows/DOS, and I expect it is so OS/2 -- but the old OS/2 code
didn't assume this. (I don't know if the person who provided the OS/2
patch was clueless or just didn't care about DOS and Windows.)
Also ripped out the support for pickling -- as of 1.5, this is no
longer needed to make pickling work.
I did some bugfixes, and fixed a major problem with the esmtp suport (I
think the person who did that part misunderstood RFC1869) Some of the
interface fer esmtp-related things has changed as a result.
I also added some documentation to the SMTP class' docstring.
choice(range(start, stop, step)) but faster. This addresses the
problem that randint() was accidentally defined as taking an inclusive
range (how unpythonic).
The code is longish because Tim Peters insisted that it reject
non-integral arguments while I insisted that it be not much slower
than randint(); the compromise satisfies both but is somewhat
convoluted.
Also changed randint() to be implemented through randrange(). This is
a semantic change because old randint() didn't test its arguments for
validity. (It also makes randrange() win any contest with randint()
:-)
involve a filesystem path. To that end:
- Changed IOError to EnvironmentError and added a hack which checks
for arg of len 3. When constructed with a 3-tuple, the third item
is the filename and this is squirreled away in the `filename'
attribute. However, for in-place unpacking backwards
compatibility, self.args still only gets the first two items. Added
a __str__() which prints the filename if it is given.
- IOError now inherits from EnvironmentError
- New class OSError which also inherits from EnvironmentError and is
used by the posix module.
Fix the implementation of quote_plus(). (It wouldn't treat '+' in the
original data right.)
Add urlencode(dict) which is handy to create the data for sending a
POST request with urlopen().
according to an idea by Harri Pasanen (but with different syntax).
This affects the 'break' and 'clear' commands and their help
functions. Also added a helper method lookupmodule().
Also:
- Try to import readline (important when pdb is used from/as a script).
- Get rid of reference to ancient __privileged__ magic variable.
- Moved all import out of functions to the top.
- When used as a script, check that the script file exists.
