The code highlighting seems to have some problems with files that don't match expected extensions.

I have a number of command line scripts that have no .php extension which have no hilighting going on, also I name my smarty templates with .htm rather than .tpl and none of the smarty highlighting occurs in them.

Is there a way to fix this?

Thanks!

There is no magic, to know what type file belongs to, phped checks it extension and matches against list of extensions in the Tools->Settings->Associations.
If you need htm to be recognized as tpl, just remove htm from HTML and add it to the list for Smarty.

Ahh that, worked, I had tried adding *.htm but hadn't removed it from HTML association.

Thanks!
