javascript - How do I provide source-level debugging for a language like VS does for TypeScript? -

-

i understand concept of using source maps javascript make debugging easier minified scripts, etc. don't how source-level debugging works typescript in visual studio (http://blogs.msdn.com/b/typescript/archive/2012/11/15/announcing-typescript-0-8-1.aspx).

for example, if create own language compiles/translates javascript, how interface browsers provide kind of source-level debugging? there standard protocol this? how visual studio it?

update

to clarify more, let's invent language called caffeinated beverage script compiles javascript. build ide language , want able set breakpoints, step through code, inspect variables, etc. in ide while javascript runs in browser. how ide communicate browser on level?

you might consider webkit's remote debugging api:

i believe that's sublime web inspector uses.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
