Subject: ANN: PyGaim released - Gaim Python plugin

PyGaim has been released.

Summary: Gaim Python plug-in. The product provides developers with the 
capability to develop python plugins for Gaim

This release is just a get it out there release and a lot of polishing 
still needs to be done.

However, it does enable a python developer to develop gaim plugins using 
python as the programming language.

The current packages is available from 
http://sourceforge.net/projects/pygaim

ToDo:

Web page
CVS
Instructions on installing and using
More examples
A interface to the gaim gui using pygtk
Lots of other stuff.

The mailing list should be up in the next 24 hours

Subject: multi regexp analyzer ? or how to do...

Hello,

here is a trouble that i had, i would like to resolve it with python,
even if i still have no clue on how to do it.

i had many small "text" files, so to speed up processes on them, i used
to copy them inside a huge one adding some king of xml separator :


[content]


content is tab separated data (columns) ; data are strings

now here come the tricky part for me :

i would like to be able to create some kind of matching rules, using
regular expressions, rules should match data on one line (the smallest
data unit for me) or a set of lines, say for example :

if on this line , match first column against this regexp and match
second column
and on following line match third column
-> trigger something

so, here is how i had tried :

- having all the rules,
- build some kind of analyzer for each rule,
- keep size of longest one L,
- then read each line of the huge file one by one,
- inside a "file", create all the subsets of length <= L
- for each analyzer see if it matches any of the subsets
- if it occurs...

my trouble is here :

"for each analyzer see if it matches any of the subset"

it is really to slow, i had many many rules, and as it is "for loop
inside for loop", and inside each rule also "for loop on subsets lines"
i need to speed up that, have you any idea ?

i am thinking of having "only rules for one line" and to keep traces of
if a rule is a "ending one" (to trigger something) , or a "must
continue" , but is still unclear to me for now...

a great thing could also have been some sort of dict with regexp
keys...

(and actually it would be great if i could also use some kind of regexp
operator to tell one can skip the content of 0 to n lines before
matching, just as if in the example i had changed "following..." by
"skip at least 2 lines and match third column on next line - it would
be great, but i still have really no idea on how to even think about
that)

great thx to anybody who could help,

best

Try the following from the shell (NOT the python shell):
mysql -u user -p
[Enter passwd]
mysql> show databases;

If MyDB isn't in the list either something went wrong with the xampp 
installation or the database for xampp got a different name. (I am no 
xampp expert, so I can't help you any further)

HTH,

Sadly, its not a solution that I'm after, but a particular toolkit that
can be used for solving that type of problem.

mysql user -p

IOW, verify you can connect to the database using the MySQL
tools first, then figure out what is different with the MySQLdb call.

try:

localhost can be a URL also (if MySQL is set up properly in the first place)

any ideas?

{okay, slight error in the command line string -- I haven't ported MySQL
from the old W98 machine to the WinXP machine yet}

Subject: python install settings...

hi,

i am running Linux Ubuntu Hoary and am trying to build the Python
numarray package, v. 1.3.2 by hand since ubuntu's repos won't be
updated until breezy.

i have python 2.4, and gcc 3.3.5

after unpacking the tar, i run "python setup.py install", as it says in
the installation instructions. i get the following:

[colfax 53] numarray-1.3.2 > python setup.py install
Using EXTRA_COMPILE_ARGS = []
running install
running build
running build_py
copying Lib/numinclude.py -> build/lib.linux-i686-2.4/numarray

I had a similiar (but different) error earlier, but then I learned I
had to set my "CC" environment variable. So I set that to "gcc". i have
tried setting my "OPT" setting to something like "-g 02" (no idea what
it means just found it somewhere, but it still didn't work.

upon closer inspection of Python's distutils sysconfig.py, is the error
being caused by the ' ' in "cc_cmd = cc + ' ' + opt"? Any ideas on this
new error? Are there packages/settings I need to take care of before i
can use Python's distutils to install stuff?

Thanks,
Jason

If you are willing to get your hands dirty with regexps:

import re
_reLump = re.compile(r"\S+")

def indices(text, chunks):
lumps = _reLump.finditer(text)
for chunk in chunks:
lump = [lumps.next() for _ in chunk.split()]
yield lump[0].start(), lump[-1].end()


def main():
text = """\
aaa bb ccc
dd eee. fff gggg
hh i.
jjj kk.
"""
chunks = ['aaa bb', 'ccc dd eee.', 'fff gggg hh i.', 'jjj', 'kk.']
assert list(indices(text, chunks)) == [(3, 10), (11, 22), (24, 40), (44,
47), (48, 51)]

if __name__ == "__main__":
main()

Not tested beyond what you see.

Subject: Re: Inheriting from object

The reason I ask is that I often (well... a couple of times anyway) see
cryptic omments like :

and if you inherit from object you get all the benefits of new
style classes

Now I know about the advantages of inheriting from the built in types
(if that's what you want to do) -but am a bit fuzzier on the 'general
benefits'.

I'm vaguely aware of properties.... I'll have to explore them at some
point.
