Ruby regex: parsing git commit messages for youtrack issue codes

I'd like to parse and remove youtrack issue codes embedded anywhere in commit messages.

For those who have never used youtrack, you can specify issue codes in commits as follows:

#<project>-<issue#> <commit msg> 
e.g. #PROJ-3 I like to use git and youtrack

or...

e.g. I'm silly #PROJ-3 and like to use git and youtrack

I have the following regex...

$remove_issue_regex = /( |^)#(\w+-\d+):? ? -? ?/

...which I feed into a sub method replacing the substring with an empty string. But it's ugly and might not work if the user formats their messages in a silly way. Does anyone know a more elegant way to do this?

$remove_issue_regex = /#\w+-\d+ (.*)/

will put the commit message after the stamp as the first capture group

Use a lookbehind,

(?<= |^)#(\w+-\d+)(?=: - )?

Rubular

OR

(?<= |^)#(\w+-\d+)(?:: - )?

Rubular

Just replace the whole string with the first captured group to get only the <project>-<issue> format.
