Regular expression to remove comment

Question

I am trying to write a regular expression which finds all the comments in text. For example all between /* */. Example:

/* Hello */

Answer 1

Unlike the example posted above, you were trying to match comments that spanned multiple lines. By default, . does not match a line break. Thus you have to enable multi-line mode in the regex to match multi-line comments.

Also, you probably need to use .*? instead of .*. Otherwise it will make the largest match possible, which will be everything between the first open comment and the last close comment.

I don't know how to enable multi-line matching mode in Sublime Text 2. I'm not sure it is available as a mode. However, you can insert a line break into the actual pattern by using CTRL + Enter. So, I would suggest this alternative:

/\*(.|\n)*?\*/

If Sublime Text 2 doesn't recognize the \n, you could alternatively use CTRL + Enter to insert a line break in the pattern, in place of \n.
