will help you {1} does not match the first occurrence; instead it means "match exactly one of the preceding pattern/character", which is identical to just matching the character (&{3} would match &&&).
In order to match the first occurrence of &, you need to use .*?:
code :
grep'^.*?&'
'^[^&]*&'

seems to work fine I'm trying to come up with a regex that would catch a TLD in a group of subdomains. So I have this: , You're almost there. Literally, your requirement would be:
code :
(?:^|\.)google\.com$
\bgoogle\.com$

like below fixes the issue Link has type [Inline] -> Target -> Inline, where Target is defined as type Target = (String, String). Your second parameter should be a tuple of two strings:
code :
test :: Block -> Block
test (Plain xs) = Link xs ("http://www.example.com/", "")
test x = x

I think the issue was by ths following , The last \b word boundary only matches if there is a word char (i.e. mostly a letter, digit, _) after the space at the end of the pattern. Since there is no such a char, the last word boundary prevents from matching.
Either remove the last \b, or - if you want to only match that space when not followed with a word char - with (?!\w) negative lookahead that will check just that.
code :
\bRemoving:\s*\w+\s*---\s*For\s+User:\s*
