Maybe you have some repport due, where few lines of code are needed, but Open Office Writer doesn’t handle .c source file, neither .py, .m
The solution:

sudo apt-get install highlight

gedit “~/.gnome2/nautilus-scripts/Highlight and open with OOO”

#!/bin/bash
#
highlight -o /tmp/highlight_temp_file.html $*
openoffice /tmp/highlight_temp_file.html
rm /tmp/highlight_temp_file.html

chmod +c “~/.gnome2/nautilus-scripts/Highlight and open with OOO”

And now, any right clic on a file, and it’s opened in OOO with nice colors.
