pychecking current source file in pythonwin

Hi.

I have tried to add pychecker as an extension to pythonwin. Now I can
have pychecker check the source file that is currently open in the
editor with a single keypress. If someone is interested, here is how
to do it:

Create an empty file in your
<pythondir>\Lib \site-packages\Python win\pywin directory. Give it a
name with .cfg as extension.

Into this file put the following lines (replace <pythondir> with the
path to your python installation):

[General]
Based On = Default
[Keys:Editor]
Shift+Ctrl+v = checksource
[Extensions]
def checksource(edi tor_window, event):
import pywin.framework .scriptutils
import os
import re

filename = pywin.framework .scriptutils.Ge tActiveFileName ()
messages = os.popen(r"<pyt hondir>\Scripts \pychecker.bat %s" %
filename)
for message in messages.xreadl ines():
print re.sub(r"(.*):( \d+):(.*)", r'File "\1", line \2, \3',
message.strip() )
messages.close( )



Start pythonwin. In the View menu select Options. Go to the Editor
tab. In the dropdown box select the name of your configuration file.
Click OK.

Now open a Python source file and press Shift+Ctrl+v. The output of
the operation can be found on the interactive screen. The script
formats the output so a double click on a pychecker message will jump
to the corresponding line in the editor.

The script should write something like "pychecker is checking your
source" into the status bar, but I haven't found out how to do that
yet. Maybe some helpful soul can help out with that.
