kiwi.environ.Library(Environment)
class documentationkiwi.environ
(View In Hierarchy)
Known subclasses: kiwi.environ.Application
A Library is a local environment object, it's a subclass of the Environment class. It's used by libraries and applications (through the Application class)
It provides a way to manage local resources, which should only be seen in the current context.
Libraries are usually instantiated in __init__.py in the topmost package in your library, an example usage is kiwi itself which does:
>>> from kiwi.environ import Library >>> lib = Library('kiwi') >>> if lib.uninstalled: >>> lib.add_global_resource('glade', 'glade') >>> lib.add_global_resource('pixmap', 'pixmaps')
which is combined with the following class in setup.py:
>>> from kiwi.dist import InstallLib >>> class InstallLib(TemplateInstallLib): >>> name = 'kiwi' >>> global_resources = dict(glade='$datadir/glade', >>> pixmap='$datadir/pixmaps') >>> >>> setup(..., >>> data_files=[('share/kiwi/glade', >>> listfiles('glade', '*.glade')), >>> ('share/kiwi/pixmaps', >>> listfiles('pixmaps', '*.png')), >>> cmdclass=dict(install_lib=InstallLib))
It may seems like a bit of work, but this is everything that's needed for kiwi to figure out how to load resources when installed and when running in an uninstalled mode, eg directly from the source tree. To locate a pixmap called kiwi.png the following is enough:
>>> from kiwi.environ import environ >>> environ.find_resource('pixmap', 'kiwi.png') '/usr/share/kiwi/pixmaps/kiwi.png' # installed mode
Which will lookup the resource kiwi.png in the domain pixmap, which points to $datadir/pixmaps (eg $prefix/share/kiwi/pixmaps) when running in installed mode and from $builddir/pixmaps otherwise.
Method | __init__ | Creates a new library, this is usually called in __init__.py in a toplevel package. All resources will be relative to the root directory. |
Method | enable_translation | Enables translation for a library |
Method | set_application_domain | Sets the default application domain @param domain: the domain |
Method | add_global_resource | Convenience method to add a global resource. This is the same as calling kiwi.environ.environ.add_resource |

Creates a new library, this is usually called in __init__.py in a toplevel package. All resources will be relative to the root directory.
Parameters | name | name of the library |
root | root directory | |
