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  there are separate keyboard shortcuts for line comments and block comments         However  I don t see that in Xcode - in fact  I don t even see a menu option to add a block comment  Is it simply not supported in Xcode  That would certainly seem to be a lame decision if so

Try command      It works for me    So  you just highlight the block of code you want to comment out and press those two keys

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    Created Automator service using AppleScript Make sure  Output  replaces selected text  is checked Enter the following code   on run  input  parameters  return     n   amp   input as string   amp       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

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

Nikola Milicevic  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

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

There is now an Xcode plugin that allows this  CComment   The easiest way to install this is to use the amazing Alcatraz plugin manager for Xcode   EDIT Apple has sadly  and wrongly  IMHO  retired the old plugin model with Xcode 8  The new plugin system is quite limited  but should allow development of a plugin like this again  For anyone interested in doing this  watch WWDC 2016 session 414  Also  please file radars for API for plugins you d like to write or see

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

i managed to get this working well via an automator task and have used shortcut to bind it to key combination ctrl option command b  all i have to do is highlight the code i want block commented in xcode and press the above keys and the selected text is block commented out using              i use code folding a fair bit so the reason i wanted this functionality was so i could easily fold down a block of commented code     code commented the usual way using    wont fold   im not familiar with using mac automator but i simply followed the instrux in the following wwdc video   in the WWDC 2012 video Session 402 - Working Efficiently with Xcode   from around 6 minutes in  there s a description of how to use the Mac OSX Automator to add a service to manipulate selected text  The example shown in the video is to remove duplicates in a selection of text using the shell commands sort and uniq  Using this approach you do the same but you enter the following command instead of what he does in the video  awk  BEGIN print      print  0 END print         note there are meant to be 2 asterisks in the previous line that for some reason are not showing      they do show up in the screenshot below so copy that as the correct command to enter   you should end up running a shell script like this    this will  for any given selected text  put the comment delimiters before and after    when you save it you should get options to name it  i called it blockcomment  and also to assign a keyboard shortcut  then you should be able to open xcode  select some text  right click  the context menu  and the name you gave to this script should show near the bottom   simply click the name and the script will run and block comment the selected code or use the keyboard shortcut you assigned   hope this helps
