I have the following strings, what I would like to get are the User name (user) and the project name (project-1) for example.

But I need two different regular expressions.

• One to get the user's name only
• One to get only the name of the project

Can you give me some advice?

https://github.com/user/project-1.git
https://github.com/user/project-1
[email protected]:user/project-1.git

CodePudding user response：

User: s/^.*github\.com[:\/]([^\/] )\/.*$/\1/ (https://regex101.com/r/EHSIvr/1)

Project: s/^.*\/([^\/] ?)(?:\.git)?$/\1/ (https://regex101.com/r/tzOFDm/1)

The links to regex101.com (which I recommend to use) also explain step by step both regex.

In particular, notice the use of quantifier ? (lazy: match as few characters as possible) in the second expression, to avoid including .git.

user: r'(?:. [:/])(. ?)(?:/)'

project: r'(?:. /)(. ?)$'

where: 
(?: ) - non-capturing group 
. - any single character
  - one or more 
$ - end of string
? - non greedy, as less as possible
