I need some help about terminals.
For Pyvon, I would like to use a script to start boths Pyvon and a 
terminal to which the verbose, errors, stats ( in short all the normal 
output) of POV is redirected; with Pyvon taking up 2/3 of the upper 
screen and the terminal the 1/3 left.

For the time being, I start konsole (KDE terminal), resize it so that it
takes up about 1/3 (at the bottem ) of the screen, type python pyvon.py 
( to start Pyvon), and then resize Pyvon to fill up the rest to the screen.

The best would be a script that test the screen resolution and does the 
rest automatically.


Something else :
How do you send a command into a terminal ( like Xterminal ) which is 
already created so that the output of the command goes back to Xterminal 
? It's the end of the day's work I am not sure my english is clear 
enough .............


Thanks

Fabien

How about something a bit more standard like Xterm rather than something that's 
desktop specific.

Maybe the X man page or Xresorces man page would be a good place to start 
here, also look at the xterm man page there is the "-geometry" option this
is explained in more detail in the X man page.

Example:

Open your Xterm like this:

xterm -e tail -f some.file.to.be.read
  
And start POV something like this:

povray -whatever -option -All_File=some.file.to.be.read 

I havn't tested anything here and there are probably better solutions 
but it may get you started.

I think this will work only if some.file.to.be.read is a FIFO (otherwise
tail will end because the file is empty).

so first do :

mknod some.file.to.be.read p

and this should work.

  Not if you use tail -f

	Just a little quick hack in c-shell demonstrating this with
two konsole windows. Cons: this is csh, any other shell would be
for sure much better; it does not take into account the size of
windows decorations and other toolbars; some applications (xterm)
do not resize properly. Pros: none  ;o)


#!/bin/csh

set width  = `xwininfo -root | grep Width | cut -d: -f2`
set height = `xwininfo -root | grep Height | cut -d: -f2`

set twothird = `echo "scale = 0; $height * 2./3" | bc -l`
set onethird = `echo "scale = 0; $height - $twothird" | bc -l`

konsole -geometry ${width}x${twothird}+0+0 &

konsole -geometry ${width}x${onethird}+0-0 &

You don't need to do this, as my example says use tail -f.

Ok, I just miss it !

But the file must exist. So either you launch PoV before xterm or you
use something like "touch some.file.to.be.read".

This works : this time I try before posting stupids tricks :-)

Yes touching the file every time Pyvon is started is a good idea, it'd
be nice to purge the file after it reaches a certain size too - and keep
previous output and let the file grow to a size specified by the user in
the config file, maybe default to something like 1 Meg.  And if the file 
is over 1 Meg when render is pressed then use > rather than >> and maybe 
even copy the old some.file.to.be.read to a backup file.

I'll try that one, because Python for once does not seem to fit the bill.
