Is there a shortcut to make a block comment in Xcode?

Question

I\'m writing ANSI-compatible C code, and hence I can\'t use the line (//) comment. I\'m using Xcode. In Sublime Text and Eclipse, and I think most other IDEs, t

Answer 1

You can assign this yourself very easily, here goes a step by step explaination.

1.) In you xCode .m file type the following, it does not matter where you type as long as it's an empty area.

/*
*/

2.)Highlight that two lines of code then drag and drop onto 'code snippet library panel' area (it's at the bottom part of Utilities panel). A light blue plus sign will show up if you do it right.

3.) After you let go of your mouse button, a new window will pop up and will ask you to add name, short cut etc; as shown. As you can see I added my shortcut to //. So every time I want a block comment I will type //. Hope this helps

If you're looking a way to convert autogenerated comment from Add Documentation action (available under cmd-shift-/) you might find it useful too:

function run(input, parameters) {
  var lines = input[0].split('\n');
  var line1 = lines[0];
  var prefixRe = /^( *)\/\/\/?(.*)/gm;
  var prefix = prefixRe.test(line1) ? line1.replace(prefixRe, "$1") : ""

  var result = prefix + "/*\n";  
  lines.forEach(function(line) {
    result += prefix + line.replace(prefixRe, "$2") + '\n';
  });
  result += '\n' + prefix + ' */';
  return result;
}

Rest the same as in @Charles Robertson answer:

Answer 3

In xcode 11.1 swift 5.0

select the code you would like to add block comment then press ⌥ + ⌘ + /

Answer 4

There is a symbol before help menu on xcode which has Edit user script. On Un/Comment Selection under comments section change my $cCmt = "//"; to my $cCmt = "#"; or whatever your IDE works with. Then by selecting lines and command + / (It's my xcode default) you can comment and uncomment the selected lines.

Here is the screenshot of the indentation issue. This is very minor, but it is strange that it seems to work so well, in your example visual.

I am also adding a screenshot of my Automator set-up...

Thanks

Update:

If I change the script slightly to:

And then select full lines in XCode, I get the desired outcome:

UPDATE:

Since I was lazy, and didn't fully implement my solution, I searched around and found BlockComment for Xcode, a recently released plugin (June 2017). Don't bother with my solution, this plugin works beautifully, and I highly recommend it.

ORIGINAL ANSWER:

None of the above worked for me on Xcode 7 and 8, so I:

1. Created Automator service using AppleScript
2. Make sure "Output replaces selected text" is checked

3. Enter the following code:

   on run {input, parameters}
   return "/*\n" & (input as string) & "*/"
   end run
   

Now you can access that service through Xcode - Services menu, or by right clicking on the selected block of code you wish to comment, or giving it a shortcut under System Preferences.
