ocaml-github: GitHub APIv3 OCaml Library

This library provides an OCaml interface to the GitHub APIv3 (JSON). It is compatible with MirageOS and also compiles to pure JavaScript via js_of_ocaml.

It is not yet complete but lib/github.atd contains the data types that have been bound so far.

There are several tests and examples in lib_test for small bits of functionality. jar contains utility programs that use the git jar facility for stored tokens.

If you are interested in easily using this library to listen for GitHub web hook events, you should look at dsheets/ocaml-github-hooks.

Debugging

Two environment variables will cause more debugging to be output:

GITHUB_DEBUG=1   # API calls output to stderr
COHTTP_DEBUG=1   # even more HTTP-level debugging

If using the bindings from the toplevel, you can also set Github.log_active to true to get the same effect as setting the GITHUB_DEBUG environment variable.

git jar

Applications that use this library will need to save authorization tokens locally, and the Github_cookie_jar module in unix helps handle this more naturally. It maps local application name to an authorization token so that the application can query the cookie jar at runtime and use the resulting token in Github API calls.

The tokens are all stored in $HOME/.github/jar/<name>, where <name> is the local name of the application.

A git-jar command will be installed to add, remove, and list the contents of this cookie jar.

$ git jar

...will display the man page.

$ git jar make avsm rwo
Enter Github password: **********
Enter 2FA code from 'app': 172217
Github cookie jar: created /home/avsm/.github/jar/rwo
Created token rwo (236241): <token>

$ git jar show avsm
Enter Github password: **********
Enter 2FA code from 'app': 001221
Cookie Name | ID       | Application                              | Note
----------------------------------------------------------------------------------
        rwo | 236241   | Real World OCaml (API)                   |
   <remote> | 340988   | Travis                                   |

Your Github application can now use it via the Github_cookie_jar module:

# #require "github.unix";;
# Github_cookie_jar.(init () |> Lwt_main.run |> get ~name:"rwo");;
- : Github_t.auth option =
Some
 {Github_t.auth_scopes = [`Public_repo];
  auth_token = "<token>";
  auth_app =
   {Github_t.app_name = "Real World OCaml";
    app_url = "https://docs.github.com/rest/reference/oauth-authorizations"};
  auth_url = "https://api.github.com/authorizations/236241";
  auth_id = 236241; auth_note = Some "rwo"; auth_note_url = None}

Manipulate GitHub releases

The Releases API in GitHub cannot itself be synched via Git, so this command-line tool lets you specify a source user/repo and destination user/repo pair, and copies all the releases from one to the other.

The git-sync-releases binary can copy all the releases from one repository to another for you.

$ git sync-releases mirage ocaml-uri avsm ocaml-uri

You can also associate binary files with any release, for example to include pregenerated build files. The git upload-release binary will do this for you.

$ git upload-release mirage ocaml-uri v1.4.0 release.tar.gz
