have i got it right, that this thread is 'bout free editor for scripting langs?
my fave programming editors (all are free if i'm correct):
Context Programmers Editor:
http://www.context.cx/ - very modest on resources, variety of highlighters (from assemblers, through scripting, c, c++, c#, java, upto latex, html etc.)
Crimson Editor:
http://www.crimsoneditor.com/ - very strong, w/ great support for command-line tools (when you use latex, gcc, asm or so, crimson is a great choice, even over some IDEs)
and of course the best of the best - Emacs:
http://www.gnu.org/software/emacs/emacs.html , binaries downloadable from many places, eg.
http://www.fis.unipr.it/pub/win/Emacs/ (try google for more places) - harder to learn, but incredibly effective once you get the grip of it
