@YarekTyshchenko Apart from the minor typo, the decoders for the new entities (Branch and BranchCommit) are missing and tests are failing.

It should not be hard to add, but let me know if you need help doing so.

@YarekTyshchenko as it is described in the GitHub API Docs # list-branches, protected and protection* keys are only included in the JSON response if the query parameter protected is set to true in the request.

That makes the protected and protection_url in the response Option values, IMHO. I've just suggested those changes, but feel free to submit any other possible solution 👍

Also, I think it would be great to test both cases, with protected and without protected query parameter. What do you think?

[YarekTyshchenko]

@JesusMtnez You are right, I must have missed that bit in the docs.Option sounds good!

[YarekTyshchenko]

I could use some help figuring out why the Travis tests are failing. I can't see anything obvious that I did wrong in Repos.scala. I'm not massively familiar with Scala yet

hey @YarekTyshchenko, the tests use a GitHub token that is not available in forks. You'd need to create a Personal Access token in Github with gists permissions (I don't remember if anyone more is necessary) and store it in the environment variable GITHUB4S_ACCESS_TOKEN before executing the tests. I can also execute them locally, I just need to find some time. Thanks

@YarekTyshchenko Greenlight! All checks are passing, we are good to merge.

[JesusMtnez]

@YarekTyshchenko do you need a new release of github4s? Just let me know if needed 😉

[YarekTyshchenko]

@JesusMtnez Let me have a quick look at #233 first. I think that should be an easy one
