@adimasuhid - Thanks for working on this. 😄

How about adding tests for flags later? For now, just add the colorls -A to the travis.yml file and remove the spec (and fixtures) for the -A flag.

[adimasuhid]

@athityakumar Sure will do. Though do you mean add specs in a separate PR or just remove specs all together?

[athityakumar]

@adimasuhid - I'd like it for specs to be added, provided specs for all flags are added. Else, it becomes too inconsistent. Hence,

• For this PR, revert the spec part. Add the Travis config.
• If you don't mind adding spec for all flag options usage (as currently done in travis.yml), please do it in a different PR. Else, no issues. We can make do with Travis build log reports as of now for reviewing PRs.

@athityakumar That makes sense thanks. Will do. I'll try to add specs for all if I have time though that's probably just the happy path for the mean time.

@athityakumar Updated as suggested.

Out of context question though: How can you reply so fast, any time of the day? haha

[athityakumar]

@adimasuhid - Haha. Purely a matter of coincidence that I'm awake at that time. 😄
