Textmate “comment” command not working properly for css code

Question

I'm having some problems when I toggle the comments in TextMate for CSS source code.

Using the shortcut CMD + / I activate the "Comment Line/Selection" command from the "source" bundle. The problem is that it inserts a series of // for all kinds of languages. For example, in CSS files it is supposed to insert a /**/ block, but it doesn't. In CSS files I also tried the "Insert Block Comment" command from the source bundle with the weird result that I get the following //.

// ----------------------------------------

instead of my code, deleting the code and inserting that.

I know I am supposed to modify the command from the bundle, but I can't figure out how and what.

This is the code of the "Comment Line/Selection" command from the "Source" Bundle:

#!/usr/bin/env ruby

# by James Edward Gray II <james (at) grayproductions.net>

# 
# To override the operation of this commond for your language add a Preferences
# bundle item that defines the following valiables as appropriate for your
# language:
# 
#   TM_COMMENT_START - the character string that starts comments, e.g. /*
#   TM_COMMENT_END   - the character string that ends comments (if appropriate),
#                      e.g. */
#   TM_COMMENT_MODE  - the type of comment to use - either 'line' or 'block'
# 

require "#{ENV["TM_SUPPORT_PATH"]}/lib/escape"

def out(*args)
  print( *args.map do |arg|
    escaped = e_sn(arg)
    $selected ? escaped.gsub("}", "\\}") : escaped.sub("\0", "${0}")
  end )
end

# find all available comment variables
var_suffixes = [""]
2.upto(1.0/0.0) do |n|
  if ENV.include? "TM_COMMENT_START_#{n}"
    var_suffixes << "_#{n}"
  else
    break
  end
end

text    = STDIN.read
default = nil  # the comment we will insert, if none are removed

# maintain selection

  $selected = true
  print "${0:"
  at_exit { print "}" }

  $selected = false

Answer 1

Ensure you have the "Source" bundle installed. In the latest Textmate 2 Alpha at the time of writing, go to TextMate -> Preferences -> Bundles -> Check "Source" bundle to install. The CMD + / shortcut should now work.

Answer 2

It is small syntax problem if you're using a Ruby higher then 1.8.7. You will find that to_a method has been removed. If you want to fix the problem all you need to do is modify the code found in this file.

In order to fix the problem you need to search for any location that they call to_a and replace it with Array("string").

In my case I did this. This also should work for you:

lines = text.to_a

with

lines = text.lines.to_a

This should be a solution for every thing. Look to the image to see what file I ended up fixing.

Answer 3

I had the same problem and it turns out that I had an SCSS bundle installed that had a preference set to use "//" for comments with a scope selector for source.css as well as source.scss.

I would check to make sure that you don't have the same SCSS bundle and if you do, change the scope selector of the comments preference to be just source.scss.

Answer 4

Cmd/ has been working for years and still is. Well, my copy of TM2 alpha is broken (doesn't work with the / in the numeric pad but, well, it's alpha) but TM 1.5.x works as it should.

You are not supposed to modify anything anywhere. The Comment Line/Selection command is smart enough to put the right kind of comment in "any" kind of file.

Did you mess with language definitions? Is your file recognized as "CSS"? Does it work when removing all or certain plugins/bundles?
