Functions
gs_plugin_initialize ()
void
gs_plugin_initialize (GsPlugin *plugin
);
Checks if the plugin should run, and if initializes it. If the plugin should
not be run then gs_plugin_set_enabled()
should be called.
This is also the place to call gs_plugin_alloc_data()
if private data is
required for the plugin.
NOTE: Do not do any failable actions in this function; use gs_plugin_setup()
instead.
gs_plugin_destroy ()
void
gs_plugin_destroy (GsPlugin *plugin
);
Called when the plugin should destroy any private data.
gs_plugin_adopt_app ()
void gs_plugin_adopt_app (GsPlugin *plugin
,GsApp *app
);
Called when an GsApp has not been claimed (i.e. a management plugin has not been set).
A claimed application means other plugins will not try to perform actions such as install, remove or update. Most applications are claimed when they are created.
If a plugin can adopt this application then it should call
gs_app_set_management_plugin()
on app
.

gboolean gs_plugin_add_search (GsPlugin *plugin
,gchar **values
,GsAppList *list
,GCancellable *cancellable
,GError **error
);
Get search results for a specific query.
Plugins are expected to add new apps using gs_app_list_add()
.
gs_plugin_add_search_files ()
gboolean gs_plugin_add_search_files (GsPlugin *plugin
,gchar **values
,GsAppList *list
,GCancellable *cancellable
,GError **error
);

Plugins are expected to add new apps using gs_app_list_add()
.
gs_plugin_add_search_what_provides ()
gboolean gs_plugin_add_search_what_provides (GsPlugin *plugin

.
gs_plugin_setup ()
gboolean gs_plugin_setup (GsPlugin *plugin
,GCancellable *cancellable
,GError **error
);
Called when the plugin should set up the initial state, and with the write lock held.
All functions can block, but should sent progress notifications, e.g. using
gs_app_set_progress()
if they will take more than tens of milliseconds
to complete.
This function will also not be called if gs_plugin_initialize()
self-disabled.

gboolean gs_plugin_add_popular (GsPlugin *plugin
,GsAppList *list
,GCancellable *cancellable
,GError **error
);
Get popular applications that should be featured on the main page as "Editors Picks". This is expected to be a curated list of applications that are high quality and feature-complete.
The returned list of popular applications are not sorted, but each GsApp has to be valid, for instance having a known state and a valid icon. If an insufficient number of applications are added by plugins then the section on the overview shell may be hidden.
Plugins are expected to add new apps using gs_app_list_add()
.

gboolean gs_plugin_add_featured (GsPlugin *plugin
,GsAppList *list
,GCancellable *cancellable

NOTE: The UI code may expect that applications have additional metadata set on
results, for instance GnomeSoftware::FeatureTile-css
.
Plugins are expected to add new apps using gs_app_list_add()
.

gboolean gs_plugin_add_unvoted_reviews (GsPlugin *plugin
,GsAppList *list
,GCancellable *cancellable
,GError **error

Plugins are expected to add new apps using gs_app_list_add()
.
gs_plugin_refine ()
gboolean gs_plugin_refine (GsPlugin *plugin
,GsAppList *list
,GsPluginRefineFlags flags
,GCancellable *cancellable
,GError **error
);
Adds required information to a list of GsApp's.
This function is only really required when "batching up" requests, and most
plugins are better using the per-app gs_plugin_refine_app()
function.
An example for when this is useful would be in the PackageKit plugin where we want to do one transaction of GetDetails with multiple source-ids rather than scheduling a large number of pending requests.
gs_plugin_refine_app ()
gboolean gs_plugin_refine_app (GsPlugin *plugin
,GsApp *app
,GsPluginRefineFlags flags
,GCancellable *cancellable
,GError **error
);
Adds required information to app
.
The general idea for flags
is that this indicates what the UI needs at the
moment. This doesn't mean you can't add more information if you have it,
for example, if we requested GS_PLUGIN_REFINE_FLAGS_REQUIRE_LICENSE
and had
to do some IO to get a blob of data, we can use gs_app_set_license()
*and*
gs_app_set_origin()
even though only the first thing was specified.
If the plugin can't handle applications of the specific kind, or if the plugin knows not of the GsApp ID then it should just ignore the request and return FALSE.
gs_plugin_refine_wildcard ()
gboolean gs_plugin_refine_wildcard (GsPlugin *plugin
,GsApp *app
,GsAppList *list
,GsPluginRefineFlags flags
,GCancellable *cancellable
,GError **error
);
Adds applications that match the wildcard specified in app
.
The general idea is that plugins create and add *new* applications rather than all trying to fight over the wildcard application. This allows the plugin loader to filter using the GsApp priority value.
gs_plugin_launch ()
gboolean gs_plugin_launch (GsPlugin *plugin
,GsApp *app
,GCancellable *cancellable
,GError **error
);
Launch the specified application using a plugin-specific method. This is normally setting some environment or launching a specific binary.
Plugins can simply use gs_plugin_app_launch()
if no plugin-specific
functionality is required.
gs_plugin_add_shortcut ()
gboolean gs_plugin_add_shortcut (GsPlugin *plugin
,GsApp *app
,GCancellable *cancellable
,GError **error
);
Adds a shortcut for the application in a desktop-defined location.
gs_plugin_remove_shortcut ()
gboolean gs_plugin_remove_shortcut (GsPlugin *plugin
,GsApp *app
,GCancellable *cancellable
,GError **error
);
Removes a shortcut for the application in a desktop-defined location.
gs_plugin_update_cancel ()
gboolean gs_plugin_update_cancel (GsPlugin *plugin
,GsApp *app
,GCancellable *cancellable
,GError **error
);
Cancels the offline update of app
.
gs_plugin_app_install ()
gboolean gs_plugin_app_install (GsPlugin *plugin
,GsApp *app
,GCancellable *cancellable
,GError **error
);
Install the application.
Plugins are expected to send progress notifications to the UI using
gs_app_set_progress()
using the passed in app
.
All functions can block, but should sent progress notifications, e.g. using
gs_app_set_progress()
if they will take more than tens of milliseconds
to complete.
On failure the error message returned will usually only be shown on the
console, but they can also be retrieved using gs_plugin_loader_get_events()
.
NOTE: Once the action is complete, the plugin must set the new state of app
to AS_APP_STATE_INSTALLED
.
gs_plugin_app_remove ()
gboolean gs_plugin_app_remove (GsPlugin *plugin
,GsApp *app
,GCancellable *cancellable
,GError **error
);
Remove the application.
Plugins are expected to send progress notifications to the UI using
gs_app_set_progress()
using the passed in app
.
All functions can block, but should sent progress notifications, e.g. using
gs_app_set_progress()
if they will take more than tens of milliseconds
to complete.
On failure the error message returned will usually only be shown on the
console, but they can also be retrieved using gs_plugin_loader_get_events()
.
NOTE: Once the action is complete, the plugin must set the new state of app
to AS_APP_STATE_AVAILABLE
or AS_APP_STATE_UNKNOWN
if not known.
gs_plugin_app_set_rating ()
gboolean gs_plugin_app_set_rating (GsPlugin *plugin
,GsApp *app
,GCancellable *cancellable
,GError **error
);
Gets any ratings for the applications.
Plugins are expected to call gs_app_set_rating()
on app
.
gs_plugin_update_app ()
gboolean gs_plugin_update_app (GsPlugin *plugin
,GsApp *app
,GCancellable *cancellable
,GError **error
);
Update the application live.
Plugins are expected to send progress notifications to the UI using
gs_app_set_progress()
using the passed in app
.
All functions can block, but should sent progress notifications, e.g. using
gs_app_set_progress()
if they will take more than tens of milliseconds
to complete.
On failure the error message returned will usually only be shown on the
console, but they can also be retrieved using gs_plugin_loader_get_events()
.
NOTE: Once the action is complete, the plugin must set the new state of app
to AS_APP_STATE_INSTALLED
or AS_APP_STATE_UNKNOWN
if not known.
If AS_APP_QUIRK_IS_PROXY
is set on the application then the actual GsApp
set in app
will be the related application of the parent. Plugins do not
need to manually iterate on the related list of applications.

gboolean gs_plugin_app_upgrade_download (GsPlugin *plugin
,GsApp *app
,GCancellable *cancellable
,GError **error

gboolean gs_plugin_refresh (GsPlugin *plugin
,guint cache_age
,GsPluginRefreshFlags flags
,GCancellable *cancellable
,GError **error

Refreshes the state of all the plugins.
The GS_PLUGIN_REFRESH_FLAGS_METADATA
flag can be used to make sure
there's enough metadata to start the application, for example lists of
available applications.
The GS_PLUGIN_REFRESH_FLAGS_PAYLOAD
flag should only be used when
the session is idle and bandwidth is unmetered as the amount of data
and IO may be large.
This is used to pre-download package updates and firmware.
All functions can block, but should sent progress notifications, e.g. using
gs_app_set_progress()
if they will take more than tens of milliseconds
to complete.
Parameters
plugin |
a GsPlugin |
|
cache_age |
the acceptable cache age in seconds, or MAXUINT for "any" |

Converts a local file to a GsApp. It's expected that only one plugin will
match the mimetype of file
and that a single GsApp will be in the returned
list. If no plugins can handle the file, the list will be empty.
For example, the PackageKit plugin can turn a .rpm file into a application
of kind AS_APP_KIND_UNKNOWN
but that in some cases it will be futher refined
into a AS_APP_KIND_DESKTOP
(with all the extra metadata) by the appstream
plugin.

);
Converts a URL to a GsApp. It's expected that only one plugin will
match the scheme of url
and that a single GsApp will be in the returned
list. If no plugins can handle the file, the list will be empty.
For example, the apt plugin can turn apt://gimp into a application.
