Block commenting in Ruby

Question

Does Ruby have block comments?

If not, is there an efficient way of inserting # in front of a block of highlighted code in TextMate?

Answer 1

You can do

=begin
  [Multi line comment]
=end

=begin and =end must be at the beginning of the line (not indented at all).

Also, in TextMate you can press Command + / to toggle regular comments on a highlighted block of code.

Answer 2

In TextMate, you can alt-drag vertically to select a column of text. This will duplicate the insertion point across all the lines you select, so you can insert or delete multiple #s at once.

UPDATE: Also in TextMate, assuming you have the right language selected, Cmd + / will toggle commenting every line in a selection regardless of language.

Answer 3

Ruby has documentation comments - they look like this:

=begin
...
=end

Not perfect but they get the job done in a pinch.

[Edit] It is important to note that =begin and =end must be at the beginning of their respective lines.

Answer 4

In TextMate 2 you can ⌘/ to comment out the current line or selected lines.
