Hi,

I just noticed that grc/python/Generator.py is hardcoded to use xterm as  
a terminal emulator. This is somewhat problematic [1] for me so I’d like  
to make it configurable, how would you rather see that done? Would  
adding a new option (like “no\_gui\_terminal\_emulator”) to the flowchart  
be too messy?

[1] xterm in ubuntu lucid is still sgid=utmp which causes it to drop  
LD\_LIBRARY\_PATH which I need since I’ve installed gnuradio to a  
temporary location. xterm also does not support pretty scrollbars that  
my users expect and does not support [freedesktop.org](http://freedesktop.org) style clipboard  
behavior ([http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=588785](http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=588785))  
unless I tell them to start xclipboard separately and then tell them to  
add some X resources…

Use an environment variable?

There’s already a GRC “prefs” support for the Gnu Radio preferences file  
that’s  
normally located in:

~/.gnuradio/config.conf

And …/grc/python/Constants.py already extracts a value for ‘doc\_dir’  
from the Gnu Radio  
preferences file. That would seem to be a good potential place to do  
that work.
