Too slow on large projects

Description

I am using XO and Ava in a large project. Both packages are too slow to be used. I never actually tried to let them finish. I usually give up after 10+ minutes. I first thought this might be related to globby: https://github.com/sindresorhus/globby/issues/43

As mentioned in that issue I created a test source that reproduces this issue. The glob targets a folder that exists only once.

I opened a separate issue in Ava. https://github.com/avajs/ava/issues/1418

Environment

OS X 10.12.5 (16F73)

I discovered the main culprit. We didn’t define quiet as a boolean, which made the glob pattern an argument to --quiet and not an actuall pattern, which resulted in XO using its default pattern, which is **/*.

Try changing it to:

- "xo": "xo --quiet './**/*.js'",
+ "xo": "xo './**/*.js' --quiet",
