How to setup Xcode for proper javascript formatting?

Question

Xcode3 (and newer ;) doesn't properly format Javascript when I type something like:

doSomething(somewhere, function(err, result) { 

It inserts a huge indentation. I tried to change Xcode formatting rules but no luck. One way or another it breaks indentations.

Is there a proper way to use Xcode for javascript development?

Answer 1

With some tweaking it is possible to modify the way Xcode indents JavaScript by supplying a custom xclangspec file. Xcode for formatting and syntax uses language definitions in xclangspec files kept in directory SharedFrameworks/DVTFoundation.framework/Versions/A/Resources. Since the formatting for C language works actually better for JavaScript than the Xcode original JavaScript formatting, it is possible to use some parts of definition for C in JS definition.

Answer 2

What worked fairly well for me is to switch the .js files to use C syntax coloring.

In XCode 4: Editor -> Syntax Coloring -> C

It still highlights numbers and strings and comments, and it indents braces in a sane way.
