Contributing to CTK

The present document aims at describing how a developer should contribute to CTK.

• The source code of CTK is currently hosted on Github [1]. See http://github.com/commonth/CTK

• It's also assumed the developer is familiar with git. There are countless amount of resources available online. A good start point could the list presented on CMake/git page [2].

• We use a topic-based workflow as documented here and thus define integration branches:
  • master Release preparation; starting point for new features (default)
  • next Development; new features published here first

PreRequisites

• Create an account on github.com
• Fork http://github.com/commontk/CTK
• Introduce yourself

$ git config --global user.name "Your Name"
$ git config --global user.email "you@yourdomain.com"

Checkout your fork

cd MyProject
git clone git@github.com:<MYACCOUNT>/CTK.git
git remote add origin git@github.com:<MYACCOUNT>/CTK.git
git remote add upstream git@github.com/commontk/CTK.git

Publishing your branch

• Having your own fork CTK allows you to backup and publish your work avoiding the hurge to merge [3]

git checkout -b new_feature
hack, hack, hack, add, commit
git push origin topic1:refs/heads/topic1

• As a shortcut, you could also enter the following. Some useful script are also available here:

git config branch.topic1.remote origin
git config branch.topic1.merge refs/heads/topic1

• Then, from the branch new_feature, you could just enter the following to backup/publish your work:

git push

• To delete a branch from your fork:

git push origin :new_feature

Checkout a branch from a different fork

• You may want to collaborate with an other developer and work conjointly on a feature.
• Let's say, jcfr published the branch awesome_feature on his fork. You should do the following to check out his branch:

git remote add jcfr git://github.com/jcfr/CTK.git
git fetch jcfr
git checkout -b awesome_feature refs/remotes/jcfr/awesome_feature

• You should now have a local branch named awesome_feature. You can now add, commit and publish your work.

Integrate your new feature

• Initially, your feature should be integrated to next.
• To integrate your change to next, you could follow the steps listed below. More details are also available here.

git fetch upstream                             # Retrieve change from upstream repository
git checkout next                              # Checkout your local "next" branch
git merge upstream                             # Make sure your local branch is up-to-date.
git merge new_feature                          # Merge locally to "next" - Your changes are now integrated
git push upstream                              # Publish your change on the official repository
git push origin                                # Publish your change on your fork

• After it has been validated and tested, it could be integrated to master. More details here.

Repeat the command listed above changing "next" into "master"
