The GitHub Gem
This gem works hand-in-hand with GitHub’s API to help you out.
Catch us in the #github room on freenode if you want to get involved. Or just fork and send a pull request.
$ gem source --add http://gemcutter.org $ gem install github
$ github <command> <args> $ gh <command> <args>
Only installs pure JSON gem
json_pure by default. If you are able to install the C-extension
json gem, it will use that instead.
gem install json github
Pulling Upstream Changes
Let’s say you just forked
github-gem on GitHub from defunkt.
$ gh clone YOU/github-gem $ cd github-gem $ gh pull defunkt
This will setup a remote and branch for defunkt’s repository at master. In this case, a ‘defunkt/master’ branch.
If defunkt makes some changes you want, simply
github pull defunkt. This will
leave you in the ‘defunkt/master’ branch after pulling changes from defunkt’s
remote. After confirming that defunkt’s changes were what you wanted, run
checkout master and then
git merge defunkt/master to merge defunkt’s changes
into your own master branch. In summary:
$ gh pull defunkt $ gh checkout master $ gh merge defunkt/master
If you’ve already reviewed defunkt’s changes and just want to merge them into your
master branch, use the
$ gh pull --merge defunkt
Fetching and Evaluating Downstream Changes
If you are the maintainer of a project, you will often need to fetch commits from other developers, evaluate and/or test them, then merge them into the project.
Let’s say you are ‘defunkt’ and ‘mojombo’ has forked your ‘github-gem’ repo, made some changes and issues you a pull request for his ‘master’ branch.
From the root of the project, you can do:
$ gh fetch mojombo master
This will leave you in the ‘mojombo/master’ branch after fetching his commits. Your local ‘mojombo/master’ branch is now at the exact same place as mojombo’s ‘master’ branch. You can now run tests or evaluate the code for awesomeness.
If mojombo’s changes are good, you’ll want to merge your ‘master’ (or another branch) into those changes so you can retest post-integration:
$ gh merge master
Test/analyze again and if everything is ok:
$ gh checkout master $ gh merge mojombo/master
The latter command will be a fast-forward merge since you already did the real merge previously.
Network Patch Queue
The github gem can also show you all of the commits that exist on any fork of your project (your network) that you don’t have in your branch yet. In order to see the list of the projects that have commits you do not, you can run:
$ gh network list
Which will show you all the forks that have changes. If you want to see what those changes are, you can run:
$ gh network commits
which will show you something like this:
9582b9 (jchris/gist) [email protected] Add gist binary 4 months ago c1a6f9 (jchris/gist~1) [email protected] Tweak Rakefile spec tasks to be a bi 4 months ago d3c332 (jchris/gist~2) [email protected] Pull out two helpers into the shared 4 months ago 8f65ab (jchris/gist~3) [email protected] Extract command/helper spec assistan 4 months ago 389dbf (jchris/gist~4) [email protected] Rename ui_spec to command_spec 4 months ago 670a1a (jchris/gist~5) [email protected] Hoist the specs into a per-binary sp 4 months ago 6aa18e (jchris/gist~6) [email protected] Hoist commands/helpers into a per-co 4 months ago ee013a (luislavena/master) [email protected] Replaced STDOUT by $stdout in specs. 2 weeks ago d543c4 (luislavena/master~3) [email protected] Exclude package folder. 8 weeks ago a8c3eb (luislavena/master~5) [email protected] Fixed specs for open under Windows. 5 months ago 33d003 (riquedafreak/master) [email protected] Make sure it exists on the remote an 5 weeks ago 157155 (riquedafreak/master~1) [email protected] Updated specs. 5 weeks ago f44e99 (riquedafreak/master~3) [email protected] Only work with a clean branch. 3 months ago
These are all the commits that you don’t have in your current branch that have been pushed to other forks of your project. If you want to incorporate them, you can use:
$ gh cherry-pick ee013a
for example to apply that single patch to your branch. You can also merge a branch, if you want all the changes introduced in another branch:
$ gh merge jchris/gist
The next time you run the ‘github network commits’ command, you won’t see any of the patches you have cherry-picked or merged (or rebased). If you want to ignore a commit, you can simply run:
$ gh ignore a8c3eb
Then you won’t ever see that commit again. Or, if you want to ignore a range of commits, you can use the normal Git revision selection shorthands - for example, if you want to ignore all 7 jchris/gist commits there, you can run:
$ gh ignore ..jchris/gist
You can also filter the output, if you want to see some subset. You can filter by project, author and date range, or (one of the cooler things) you can filter by whether the patch applies cleanly to your branch head or not. For instance, I can do this:
$ ./bin/github network commits --applies ca15af (jchris/master~1) [email protected] fixed github gemspecs broken referen 8 weeks ago ee013a (luislavena/master) [email protected] Replaced STDOUT by $stdout in specs. 2 weeks ago 157155 (riquedafreak/master~1) [email protected] Updated specs. 5 weeks ago f44e99 (riquedafreak/master~3) [email protected] Only work with a clean branch. 3 months ago $ ./bin/github network commits --applies --project=riq 157155 (riquedafreak/master~1) [email protected] Updated specs. 5 weeks ago f44e99 (riquedafreak/master~3) [email protected] Only work with a clean branch. 3 months ago
Pretty freaking sweet. Also, you can supply the –shas option to just get a list of the shas instead of the pretty printout here, so you can pipe that into other scripts (like ‘github ignore’ for instance).
If you’d like to see a summary of the open issues on your project:
$ gh issues open ----- Issue #135 (2 votes): Remove Node#collect_namespaces * URL: http://github.com/tenderlove/nokogiri/issues/#issue/135 * Opened 3 days ago by tenderlove * Last updated about 1 hour ago I think we should remove Node#collect_namespaces. Since namespace names are not unique, I don't know that this method is very useful. ----- Issue #51 (0 votes): FFI: support varargs in error/exception callbacks * URL: http://github.com/tenderlove/nokogiri/issues/#issue/51 * Opened 4 months ago by flavorjones * Last updated about 1 month ago * Labels: ffi, mdalessio we should open JIRA tickets for vararg support in FFI callbacks then we should format the libxml error messages properly in the error/exception callbacks -----
If you want to additionally filter by time:
$ gh issues open --after=2009-09-14
Or filter by label:
$ gh issues open --label=ffi
