regex - Grep with ruby the gemlist -

-

i'm trying grep gem list. list with

bundlelist = `bundle show`

result

"gems included bundle:\n  * cfpropertylist (2.3.1)\n  * abstract_type (0.0.7)\n  * actionmailer (4.2.3)\n  * actionpack (4.2.3)\n"

i like:

=> ["cfpropertylist",  "abstract_type",  "actionmailer",  "actionpack"]

when try grep on it, bundlelist.scan(/\*.*\(/). result is:

=> ["* cfpropertylist (",  "* abstract_type (",  "* actionmailer (",  "* actionpack ("]

use lookbehind , lookahead instead:

/(?<=\* ).*?(?= \()/

what means minimum thing preceded star + space , followed space + opening bracket.
