Make gitql available through homebrew to be installed via command brew install gitql
A sub-task of #63

I'll start working on this first

[jsixface]

@cloudson if libgit2 library is already installed in the system, can we go ahead and build gitql directly with go build. Assuming the dynamic library path is setup.

[filhodanuvem]

Looks a good idea @jsixface .

[jsixface]

@cloudson I was trying a ask a question there 😃 . Trying to find out why the fork libgit2 and git2go was used rather than original repos. If tagging to a specific version is needed the new dependency manager in go can help.

[filhodanuvem]

That's the exact reason @jsixface . At that time we had (I guess) just go get and I remember that in few days using the original repos we had a lot of problems. Do you think that go dep can solve it?

[jsixface]

That makes sense. Yeah dep can solve the versioning issue and can stick to a specific tag. That way we make libgit2 a system dependency and have gitql as installable software.

@cloudson is this still open , if yes would like to work on it

[filhodanuvem]

@isaeef definetly it's open and we would love to get your help. 😊

Hey @filhodanuvem, I created a formula here: https://github.com/ankane/homebrew-core/blob/master/Formula/gitql.rb

However, it fails with:

error: "Invalid libgit2 version; this git2go supports libgit2 v0.27"
# error "Invalid libgit2 version; this git2go supports libgit2 v0.27"
  ^
1 error generated.

Is it possible to support the latest version of libgit2 (1.0.1)?

[renatosuero]

what about use to release new version including homebrew?

[filhodanuvem]

First of all, thanks for the effort @ankane, I just notice your message now, so sorry for the late.
Currently gitql depends of git2go, which uses the libgit2. It seems that git2go supports libgit2 1.0, so we could upgrade and check it.

[ankane]

Great, happy to test again once #94 is merged (fwiw, it looks like there are some references in the code to cloudson/git2go that aren't in the PR).

[filhodanuvem]

Just a question, in the formula, can we freeze the libgit2 to 1.0.1? I'm worried that in few months it will start breaking because in gitql is not going to require the latest version of git2go/libgit2.

[ankane]

Homebrew has a few versioned formula, but from my understanding, it's only for very popular packages (the current libgit2 formula always references the latest version). With the 1.0 release, all 1.x releases should be backward compatible according to the release notes:

This is release v1.0 "Luftschloss", which is the first stabe release of
libgit2. The API will stay compatible across all releases of the same major
version.

[filhodanuvem]

@ankane we just made a change that remove the libgit2 dependency, if you are able to try again on homebrew that would be awesome. I'm closing #94 since it's not needed anymore.

[ankane]

@filhodanuvem works great. Will submit whenever a new release is out.

[filhodanuvem]

Done @ankane

[ankane]

Great, submitted: Homebrew/homebrew-core#62091

[filhodanuvem]

Thank you so much @ankane

[ankane]

brew install gitql

is now available.

[filhodanuvem]

Amazing! Thanks a lot @ankane for the effort. I'm closing this.

[ankane]

np, thanks for updating the project to make it work.
