Question

Given a file like this:

'declare a string variable
Dim s as string

For x = 1 to 10
 ' add Hello to string
 s=s+"Hello"
End for

I need a regex to strip out all the comments in the code:

Regex would return:

'declare a string variable
' add Hello to string

Note that there may be whitespace before the quote and after the quote.

If it makes a difference I am intending to run this through grep to get all comments from a bunch of *.vb files.

Answer 1

search for this

^\s*'

^ means at the beginning of the line
\s* means to match as much space as possible (optionally no space)
' is the comment that you’re looking for

and match any lines that match that regex, and you can splice out all of the comments
