## Description

## 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.

#### Parameters

plugin | a GsPlugin |

### gs_plugin_destroy ()

    void
    gs_plugin_destroy (GsPlugin *plugin);

Called when the plugin should destroy any private data.

#### Parameters

plugin | a GsPlugin |

### 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` .

#### Parameters

plugin | a GsPlugin |
app | a GsApp |

### gs_plugin_add_search ()

    gboolean
    gs_plugin_add_search (GsPlugin *plugin,
                          gchar **values,

                          GCancellable *cancellable,
                          GError **error);

Get search results for a specific query.

Plugins are expected to add new apps using `gs_app_list_add()`.

#### Parameters

                           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()`.

#### Parameters

plugin | a GsPlugin |
list | a GsAppList |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

#### Returns

`TRUE` for success or if not relevant

    gs_plugin_add_featured (GsPlugin *plugin,
                            GsAppList *list,
                            GCancellable *cancellable,
                            GError **error);

Get applications that should be featured as a large full-width banner on the overview page. This is expected to be a curated list of applications that are high quality and feature-complete.

The returned list of popular applications are randomized in a way so that the same application is featured for the entire calendar day.

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()`.

#### Parameters

plugin | a GsPlugin |
list | a GsAppList |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

#### Returns

`TRUE` for success or if not relevant

### gs_plugin_add_unvoted_reviews ()

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

Gets the list of unvoted reviews. Only applications should be returned where there are reviews, and where the user has not previously moderated them. This function is supposed to be used to display a moderation panel for reviewers.

Plugins are expected to add new apps using `gs_app_list_add()`.

#### Parameters

plugin | a GsPlugin |
list | a GsAppList |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

#### Returns

`TRUE` for success or if not relevant

### 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.

#### Parameters

plugin | a GsPlugin |
list | a GsAppList |
flags | a GsPluginRefineFlags, e.g. `GS_PLUGIN_REFINE_FLAGS_REQUIRE_LICENSE` |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

#### Returns

`TRUE` for success or if not relevant

### 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.

#### Parameters

plugin | a GsPlugin |
app | a GsApp |
flags | a GsPluginRefineFlags, e.g. `GS_PLUGIN_REFINE_FLAGS_REQUIRE_LICENSE` |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

#### Returns

`TRUE` for success or if not relevant

### 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.

#### Parameters

plugin | a GsPlugin |
app | a GsApp |
list | a GsAppList |
flags | a GsPluginRefineFlags, e.g. `GS_PLUGIN_REFINE_FLAGS_REQUIRE_LICENSE` |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

#### Returns

`TRUE` for success or if not relevant

### 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.

#### Parameters

plugin | a GsPlugin |
app | a GsApp |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

#### Returns

`TRUE` for success or if not relevant

                            GError **error);

Adds a shortcut for the application in a desktop-defined location.

#### Parameters

plugin | a GsPlugin |
app | a GsApp |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

### 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`.

#### Parameters

plugin | a GsPlugin |
app | a GsApp |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

#### Returns

`TRUE` for success or if not relevant

### gs_plugin_app_remove ()

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.

#### Parameters

plugin | a GsPlugin |
app | a GsApp |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

#### Returns

                              GError **error);

Gets any ratings for the applications.

Plugins are expected to call `gs_app_set_rating()` on `app` .

#### Parameters

plugin | a GsPlugin |
app | a GsApp |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

#### Returns

### 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.

#### Parameters

plugin | a GsPlugin |
app | a GsApp |
cancellable | a GCancellable, or `NULL` |
error | a GError, or `NULL` |

#### Returns

`TRUE` for success or if not relevant

                       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" |
flags | a bitfield of GsPluginRefreshFlags, e.g. `GS_PLUGIN_REFRESH_FLAGS_METADATA` |

                           GError **error);

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.

Plugins are expected to add new apps using `gs_app_list_add()`.
