## Description

TotemPlugin is a general-purpose architecture for adding plugins to Totem, with derived support for different programming languages.

## Details

### TOTEM_PLUGIN_REGISTER()

    #define             TOTEM_PLUGIN_REGISTER(TYPE_NAME, TypeName, type_name)

Registers a plugin with the Totem plugin system, including registering the type specified in the parameters and declaring its activate and deactivate functions.

`TYPE_NAME` : | the name of the plugin type, in UPPER_CASE
`TypeName` : | the name of the plugin type, in CamelCase
`type_name` : | the name of the plugin type, in lower_case

### TOTEM_PLUGIN_REGISTER_CONFIGURABLE()

    #define             TOTEM_PLUGIN_REGISTER_CONFIGURABLE(TYPE_NAME, TypeName, type_name)

Registers a configurable plugin with the Totem plugin system, including registering the type specified in the parameters and declaring its activate and deactivate and widget creation functions.

`TYPE_NAME` : | the name of the plugin type, in UPPER_CASE
`TypeName` : | the name of the plugin type, in CamelCase
`type_name` : | the name of the plugin type, in lower_case

### totem_plugin_find_file ()

    char *              totem_plugin_find_file              (const char *plugin_name,
                                                             const char *file);

Finds the specified `file` by looking in the plugin paths listed by `totem_get_plugin_paths()` and then in the system Totem data directory.

This should be used by plugins to find plugin-specific resource files.

`plugin_name` : | the plugin name
`file` : | the file to find
Returns : | a newly-allocated absolute path for the file, or `NULL`

### totem_plugin_load_interface ()

    GtkBuilder *        totem_plugin_load_interface         (const char *plugin_name,
                                                             const char *name,
                                                             gboolean fatal,
                                                             GtkWindow *parent,
                                                             gpointer user_data);

Loads an interface file (GtkBuilder UI file) for a plugin, given its filename and assuming it's installed in the plugin's data directory.

This should be used instead of attempting to load interfaces manually in plugins.

`plugin_name` : | the plugin name
`name` : | interface filename
`fatal` : | `TRUE` if it's a fatal error if the interface can't be loaded
`parent` : | the interface's parent GtkWindow. [allow-none]
`user_data` : | a pointer to be passed to each signal handler in the interface when they're called. [allow-none]
Returns : | the GtkBuilder instance for the interface. [transfer full]

### totem_get_plugin_paths ()

    char **             totem_get_plugin_paths              (void);

Return a `NULL`-terminated array of paths to directories which can contain Totem plugins. This respects the GSettings disable_user_plugins setting.

Returns : | a `NULL`-terminated array of paths to plugin directories. [transfer full]
