[Visualpython-users] Mainly Linux

[Bruce S. <ba...@an...>]

There is a new Idle zip file available, of interest mainly to Linux users 
(and there is a new full Linux package incorporating the Idle update).

On Linux there was a several-second delay in closing an Idle window. 
Stephen Gava, who is working on a new version of Idle (starting from Dave 
Scherer's original work), found a fix for this which I've incorporated. The 
fundamental problem seems to be that Python itself is using an older 
version of Tcl/Tk which misses a fix that gets rid of the slow window 
closing. Gava used a work-around in the Idle file EditorWindow.py.

Just in case there are unknown side effects for Linux users, I include in 
the idle_VPython folder the old version of EditorWindow.py as 
EditorWindow_slow_close.py, to which you could revert.

P.S. I also made the default Idle font size in config-unix.txt be 12 point 
instead of 10, after observing on several Linux and Unix systems running 
X11 that 10 invoked a very small font. I would be interested in comments 
from Linux users about what this default should be.

[Visualpython-users] Did I correctly uninstall everything?

[Kevin C. <kj...@gr...>]

Hi,

I had VPython working okay under Python 1.5.2, but finally, almost
everything I use is becoming 2.2 capable.  So, I decided to switch
VPython as well.  However, as I already had python 2.2 (via RPM)  
installed, I didn't want to reinstall it, and assumed I could just start
with the VPyton tarball.

The VPython install put a whole lot of stuff on the system that I
already had elsewhere, and failed to install VPython itself.  (I suspect
it failed because it was anticipating its own flavor of Python 2.2 and
whatever else would have been installed with that tarball.)

I've decided to uninstall for the time being.  So far, I've removed the
following trees and/or files:

     /usr/local/bin/idle
     /usr/share/doc/python/*
     /usr/local/lib/python2.2/site-packages/Tools/*
     /usr/local/lib/python2.2/site-packages/visual/*
     /usr/share/python-visual/*

Did I get everything that the VPython installer tinkered with?

Thanx.

Sorry about that. Since you had already installed Python 2.2, you missed 
seeing the comment at the end of the Python 2.2 installation instructions 
about having to modify the Visual install script if Python 2.2 is in a 
different place. Thanks to your experience, I've moved this comment to the 
start of the VPython installation instructions.

A better installation scheme would be to use the Python distutils 
mechanism, which would put the burden on Python of figuring out where to 
put auxiliary files. David Andersen figured out the basic scheme for this, 
but we haven't yet put together a complete installer based on the distutils 
mechanism.

Examining the VPython install file, the only thing I see that you missed is 
/usr/local/bin/visual-demos (an alias to bring up IDLE, pointing at the 
VPython demo programs).
