Help with capturing with regexp

Question

I have this list:

foo chef.rb baz
bar cucumber.rb bar
baz gem.rb foo

I want to capture all the names without .rb.

My current regexp looks like this:

/([^\s](?:.)*?.(?:rb))/i

But it captures the .rb too.

How do I capture just the base name?

Thanks.

Answer 1

Use this regex instead:

/(\w*?)\.rb\s*.*/i

And your base-name will be in the 1st capture group.

See it on rubular.

Answer 2

This is a bit simpler: /(\S+).rb(?:$|\s)/

Any non-space chars followed by .rb followed by either the end of line or a space.
