Backport #718: Emacs ruby-mode does not show comment #@var correctly

• Status: Closed
• Assignee: matz (Yukihiro Matsumoto)

=begin
Normal comments are shown correctly, ie. correctly colored. However, when commenting an instance variable without a
leading space, the color of the comment is the same as the color of an uncommented instance variable.

To reproduce, type the following in Emacs in a buffer with ruby-mode:

this does work

@var this does also work (shown in comment color)

#@var this does not work (shown in instance variable color)
=end

=begin
This is because #@ and #$ are not always comments. An example:

  $ ruby -e '$f = "world"; puts "hello #$f"'
  # => hello world

This also applies to class variables.

The mode could be changed to make sure that it parses #@/#$ as a comment only if it's not inside a string (I don't know about any other edge cases like the one noted above).
