- Dependency Information
- ----------------------
- .. class:: BaseDependency
-
- The :class:`BaseDependency` class defines various attributes for accessing
- the parts of a dependency. The attributes are as follows:
-
- .. attribute:: name
-
- The name of the dependency
-
- .. attribute:: relation
-
- The relation (>>,>=,==,<<,<=,)
-
- .. attribute:: version
-
- The version or None.
-
- .. attribute:: preDepend
-
- Boolean value whether this is a pre-dependency.
-
- .. class:: Dependency
-
- The dependency class represents a Or-Group of dependencies. It provides
- an attribute to access the :class:`BaseDependency` object for the available
- choices.
-
- .. attribute:: or_dependencies
-
- A list of :class:`BaseDependency` objects which could satisfy the
- requirement of the Or-Group.
-
-
- Origin Information
- -------------------
- .. class:: Origin
-
- The :class:`Origin` class provides access to the origin of the package.
- It allows you to check the component, archive, the hostname, and even if
- this package can be trusted.
-
- .. attribute:: archive
-
- The archive (eg. unstable)
-
- .. attribute:: component
-
- The component (eg. main)
-
- .. attribute:: label
-
- The Label, as set in the Release file
-
- .. attribute:: origin
-
- The Origin, as set in the Release file
-
- .. attribute:: site
-
- The hostname of the site.
-
- .. attribute:: trusted
-
- Boolean value whether this is trustworthy. An origin can be trusted, if
- it provides a GPG-signed Release file and the GPG-key used is in the
- keyring used by apt (see apt-key).
-
- Examples
- ---------
- .. code-block:: python
-
- import apt
-
- cache = apt.Cache()
- pkg = cache['python-apt'] # Access the Package object for python-apt
- print 'python-apt is trusted:', pkg.candidateOrigin.trusted
-
- # Mark python-apt for install
- pkg.markInstall()
-
- print 'python-apt is marked for install:', pkg.markedInstall
-
- print 'python-apt is', pkg.summary #Python interface to libapt-pkg
-
- # Now, really install it
- cache.commit()
