[IPython-dev] WxIpython Linux hell :) was RE: wxIPython 0.6 (Multithreaded and current bug list flushed)

Hi Prabhu,

I've just installed all the things on my debian.
First of all, ouch!
What a difference! On linux it is unusable!
As you said text is black (solved now), there is an issue with locale:
Can you try locale.getpreferredencoding() and tells if you've got a result?
(here on my debian the current command works.. :( )

There is a lot focus loosing problem, and backspace make loose the focus anf
widget go on the top line!!!
Argghh.
And ho yes... stdin/out is redirected to console...

Most of problem I has solved on windows have not been solved on linux...
Will work on it.
Excuse me to have delivered a so poor linux version...

More news for next week ;)

Cheers,
Laurent

Yes, the traceback is in color and seems to render OK.

If I change the bg to white and fg to black things are better.  BTW, I 
can see output text just fine, just the input line is broken.

Ahh, cool, this fixes it and I can use Python.  However, I just did this:

import string
string??

and get a core dump!  Otherwise if I do this:

?

I get the help on the terminal and not on the wx shell.  If I do !ls for 
example the output is listed on the shell I launched the wxIPython shell 
from.  If I hit tab, I get completion (on the wx widget) but I also 
loose keyboard focus.

These sound like small linux specific issues.

In [1]: import locale

In [2]: print locale.getdefaultlocale()
(None, None)

HTH.
