Development¶
The homepage of joblib with user documentation is located on:
http://packages.python.org/joblib/
Getting the latest code¶
To get the latest code using git, simply type:
git clone git://github.com/joblib/joblib.git
If you don’t have git installed, you can download a zip or tarball of the latest code: http://github.com/joblib/joblib/archives/master
Installing¶
As any Python packages, to install joblib, simply do:
python setup.py install
in the source code directory.
Joblib has no other mandatory dependency than Python (at least version 2.6). Numpy (at least version 1.3) is an optional dependency for array manipulation.
Workflow to contribute¶
To contribute to joblib, first create an account on github. Once this is done, fork the joblib repository to have you own repository, clone it using ‘git clone’ on the computers where you want to work. Make your changes in your clone, push them to your github account, test them on several computer, and when you are happy with them, send a pull request to the main repository.
Running the test suite¶
To run the test suite, you need nosetests and the coverage modules. Run the test suite using:
nosetests
from the root of the project.
Building the docs¶
To build the docs you need to have setuptools and sphinx (>=0.5) installed. Run the command:
python setup.py build_sphinx
The docs are built in the build/sphinx/html directory.
Making a source tarball¶
To create a source tarball, eg for packaging or distributing, run the following command:
python setup.py sdist
The tarball will be created in the dist directory. This command will compile the docs, and the resulting tarball can be installed with no extra dependencies than the Python standard library. You will need setuptool and sphinx.
Making a release and uploading it to PyPI¶
This command is only run by project manager, to make a release, and upload in to PyPI:
python setup.py sdist bdist_egg register upload
Updating the changelog¶
Changes are listed in the CHANGES.rst file. They must be manually updated but, the following git command may be used to generate the lines:
git log --abbrev-commit --date=short --no-merges --sparse
