You're running the command (which command? r.colors?) with no arguments. For many commands, this will bring up a Tcl/Tk GUI (unless GRASS_UI_TERM is set, in which case it will use a Q&A dialogue on the terminal). This behaviour is hard-coded into G_parser(). If you want to use a Python GUI, modify your script to invoke the command with --interface-description and feed that to the Python GUI. Or modify G_gui() to optionally invoke a wxPython GUI instead of the Tcl/Tk one. > When I try to launch it from within the wxPython GUI, it will not launch and > gives the error... > > IOError: Couldn't fetch interface description for command <rules_colors.py>. > > > Indeed if I try to launch it from the command line with... > > python rules_colors.py --interface-description > > ...it gives me an error and does not recognize the > \xB3\x8Binterface-description\xB2 > flag. Is the Python interpreter trying to process --interface-description itself? Does: python -- rules_colors.py --interface-description work? What about: chmod +x rules_colors.py ./rules_colors.py --interface-description ? [BTW, please use a sane mail client, at least for mailing lists. If you have to use a Mac-specific encoding (MacRoman?), at least ensure that it's labelled as such, and not as ISO-8859-1. Although, that in itself won't affect the fact that it's decided to convert "--" to an em-dash. If it has a "smart quotes" option, turn it off.] -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grass-dev mailing list [email protected] http://grass.itc.it/mailman/listinfo/grass-dev
