Distribute extension to install components listed in extras_require
Project description
This package adds a command to distribute to interact with the extra components listed in extras_require.
For example, you could write a setup.py containing:
setup( name="Project-A", ... extras_require={ 'PDF': ["ReportLab>=1.2", "RXP"], 'reST': ["docutils>=0.3"], } )
Then distribute-install_component allows you to write:
$ python setup.py install_component PDF reST
to install the dependencies needed for these features.
Commandline Arguments
install_component takes a list of components to install dependencies for. These must be listed in the extras_require section of the package.
The -l option can be used to list the components available.
Configuring a package
To make distribute-install_component available in your package, you can add it to setup_requires in your setup.py:
setup( name='myproject', ... setup_requires=[ 'distribute-install_component', ] )
Tips
You can use distribute-install_requires to provide development dependencies, such as documentation builders or testing packages:
setup( name='myproject', ... setup_requires=[ 'distribute-install_component', ], extras_require={ 'test': ['nose==1.1.2', 'mock==0.8.0'], 'docs': ['Sphinx>=1.1.3', 'sphinxcontrib-httpdomain==1.1.7'], } )
Then normal users can just run
$ python setup.py install
While developers can run
$ python setup.py develop install_component test docs
