(Note: the coloring is by no means perfect or even all that logical, so please tweak to whatever extent you desire.)
I use AMPL a lot in my research and I wanted gedit (my linux IDE of choice) to color the syntax to make programming easier.
Below is a quick run down of how to get syntax coloring / syntax highlighting working in Fedora 14 (same procedure works in F12 and F13 as far as I can tell).
Create AMPL Language File
This should be placed in:
~/.local/share/gtksourceview-2.0/language-specs/ampl.lang
<?xml version="1.0" encoding="UTF-8"?>

Since this overloads the text/plain MIME-type, this is all you need to do, however AMPL files may not open in gedit automatically colored correctly. To fix this, you will want to define a MIME-type of text/x-ampl.
Define AMPL MIME-type
This should be placed in:
~/.local/share/mime/text/x-ampl.xml
<?xml version="1.0" encoding="utf-8"?> <mime-type xmlns="http://www.freedesktop.org/standards/shared-mime-info" type="text/x-ampl"> <!--Created automatically by update-mime-database. DO NOT EDIT!--> <comment>AMPL Source</comment> <glob pattern="*.mod"/> <glob pattern="*.dat"/> <glob pattern="*.run"/> </mime-type>
Alternatively, you could add lines 2-8 to
/usr/share/mime/packages/freedesktop.org.xml
… and then run
sudo update-mime-database /usr/local/share/mime
… to update the mime database.
