Migration from CVS to Git
We are currently testing the benefits of migration to git distributed version control.
Currently we have a git repository hosted at github.com:
This is the official branch, it's synchronized with the main CVS trunk every hour, so it should be up to date most of the time.
All developers and potential contributors are encouraged to try out this repository.
Below you can find rudimentary instructions on how to develop biopython with git.
First, you need to have git installed on your computer.
Git (http://git-scm.com/) is now available for all major operating systems, you can get it
- Linux: Git is now packaged in all major linux distributions, you should find it in your package manager.
- Mac OS X: http://code.google.com/p/git-osx-installer/
- Windows: There are two options: [[MsysGit]] or running the compiled git under Cygwin. You can find more information in [[this github guide]]
Getting a github account (Optional)
Once you have git installed on your machine, you can get the code and start developing, However, since the code is hosted at github, you can use more features if you sign up for github account. This is completely optional but if you do sign up all other developers will be able to see (and review) the changes you have made.
If you dan't already have a github account:
- create one here http://github.com/plans (the free plan is absolutely enough)
- Upload an ssh public key by clicking on 'account' after having logged in
Obtaining the source code
There are two ways of getting the code tree onto your machine. They're not that different, in fact both will result in a diretory on your machine containing a full copy of the repository on your machine. However, if you have a github account, you can make your repository a public branch of the project. If you do so, other people will be able to easily review your code, make their own branches from it or merge it back to the trunk.
In fact you can change this later, using the .git/config file, but to make it easier I'll describe the two possibilities separately.
Forking biopython using a github account
If you are logged in to github, you can go to the biopython repository page
and click on a button named 'Fork'. Yes, it's that easy.
It will create a fork (basically a copy) of the official biopython repository your personal account.
Now, assuming that you have git installed on your computer, execute the following commands locally on your machine:
$: git clone email@example.com:<your username>/biopython.git
Where <your username>, not surprisingly, stands for your github username. You have just created a local copy of the biopython repository on your machine.
You may want to also link your branch with the official distribution:
$: git remote add official_dist git://github.com/biopython/biopython.git
