Well, I think the URL scheme should be for more “global” actions. Not per-document actions, since there is no good way to specify what document we wish to work on, and also, this seems a bit like just hacking in some poor man’s scripting system using something which is not meant for it, e.g. the security issue you mention (which just tax general use and make it useless outside a TM context despite being a global URL scheme).

If this is for commands with HTML output we already have a TextMate JavaScript object. This seems better to use for communication than a global URL scheme: https://github.com/textmate/textmate/blob/master/Frameworks/HTMLOutput/src/helpers/HOJSBridge.mm#L42

I haven’t given scripting API that much thought, but if we add it, let’s try to do it right :)

There’s a major challenge though in figuring out what exactly should be used, AppleScript is just so God damn awful, but sort of the only system for “scripted” application IPC. Though it might be bearable if used with AppScript.
