Released in 1.19.0 🎉

I had always intended for --grep to work this way. The WIP on 2.0 implements this, maybe we could pull it out of that branch? https://github.com/peridot-php/peridot-core/commits/master - the commits starting on June 21 implemented this feature.

I kept reaching for the 1.* branch for new projects because its stable and available ¯_(ツ)_/¯

Will try to submit PR soon, thanks

@fesor What do you think of #185? I believe it would probably solve this problem too.

[ezzatron]

This functionality will be available next release via new --focus and --skip options. But perhaps even better, focused specs will allow you to simply prefix it() or describe() with an f (e.g. fit(), fdescribe()) to temporarily focus on a specific part of your suite.

See #199 for more details.
