I am in XCode 4.2 and I am trying to use the keyboard shortcut to comment out a block of code (command-/). When I do this it puts a double slash at the beginning of each line. The code does not become greyed out to indicate it is a comment. If I use the old “–” the line becomes greyed out.
I though this was just a visual problem, but I actually tried commenting out a problem line with the double-slash and when I build the project still errors. It appears that commenting out with double-slash actually doesn’t do anything.
Anyone know what is going on? I find it really useful to be able to select a section of code and just comment it all in one keystroke. Right now I have to go in line by line and type “–”.

You should use the AppleScript way of commenting code, eventually the code is interpreted by the interpreter and will ignore the comments.
(*multi-line comments
should be used this way
to comment blocks*)
--a single line comment
As DJ says, you need to use the AS comment strings: “–”, “#” or “(…)”. The “//” sequence is for C code.
Cool. Thanks. I wish there was a preference to change the default commenting from // to – so I could use the keyboard shortcut. I guess if I need to comment out a huge block I will use the shortcut and then do a find/replace on // to --.
Thanks.
You can do the editing in an external editor. Blatant plug time: If you use my AppleScriptObjC Explorer, it has comment/uncomment commands (and lots of other ASObjC-related goodies).
Cool! I’ll check it out. Yeah, I don’t like the editor at all. I looked at Late Night Software’s script editor but it is expensive. I don’t know that I can get my complany to spend the money to buy it.
I’ll take a look today. Thanks.

Strange. I downloaded AppleScript ObjC Explorer, but when I right-click on my applescript file in XCode the item “Open in External Editor” is greyed out. I looked through all the preferences and I can’t find a place to set an external editor.
What am I missing??
It’s covered in the documentation. Essentially you find a .applescript file in the Finder, choose Get Info, change the Open with: app, and click the Change All button.
Ahhhh. Thanks. I saw that and thought it was just for the convenience of being able to double-click the file and open it in the right app.
It works now. Thanks!
