Introduction

We had several Fabric scripts which violated DRY. Class-based Fabric script can solve this issue. This is a hack to enable the definition of Fabric tasks as methods in a class instead of just as module level functions. This class-based approach provides the benefits of inheritance and method overriding.

Example usage:

from fabriclassed import initialize
from fabriclassed.base import BaseFabric, DjangoFabric, VirtualenvFabric
from fabric import api as fab

class Fabric(BaseFabric):
    remote_project_path = '/local/path/to/my_project'
    local_project_path = '/remote/path/to/my_project'

    def fab_task(self):
        '''My website task'''
        fab.local('echo "Hello world"')

__all__ = initialize(Fabric(), __name__)

Every method with prefix 'fab_' will became a fabric command. Running fab -l gives:

$ fab -l
Available commands:

    del_pyc          Remove all .pyc files inside in fabfile and child direc...
    search           Search string amoung source code inside directories fro...
    task             My website task

Running fab task gives:

$ fab task
[localhost] local: echo "Hello world"
Hello world

Done.

Extended usage with Django under Virtualenv:

DjangoFabric and VirtualenvFabric classes contains various of tools to work with Django in Virtualenv environment. You can use both of these toos together or separately, as you like.

Example of Fabric class with a bunch of properies:

from fabriclassed import initialize
from fabriclassed.base import BaseFabric, DjangoFabric, VirtualenvFabric
from fabric.api import lcd, local

class Fabric(BaseFabric, DjangoFabric, VirtualenvFabric):
    search_dirs = []

    hosts = ['website.com']
    remote_project_path = '/local/path/to/my_project'
    local_project_path = '/remote/path/to/my_project'

    # django settings
    managefile_path = './manage.py'
    test_default_app = 'name_of_my_main_django_application'
    test_settings = 'settings_test_special_file'
    shell_plus = True
    devserver_port = 8000
    devserver_params = ''
    fixtures_dir = 'fixtures'
    fixtures_format = 'json'
    fixtures_map = (
        'sites.site',
    )

    # virtualenv settings
    use_virtualenv = True
    virtualenv_dir = 'env'
    patched_applications = [
        # list of virtualenv patched applications
    ]
    diff_dir = 'my_relative_to_project_diffs_dir'
    applications_dir = 'my_relative_to_project_apps_dir'

__all__ = initialize(Fabric(), __name__)

Running fab -l gives:
