Hi,
wanted to mention that I created an edit mode/background syntax highlight
extension for Sublime Text 2 (probably works with Text Mate, too) and it
proved to be quite handly in daily work with ESP files. Actually seeing
which script chunk runs where spares some brain power... I don't know how
you deal with it but looking for <% %> and ${} tags killed my soul several
times before putting together this little mod.
Feel free to love it or hate it: https://github.com/balazstth/subl-esp
Cheers,
