## Includes

    #include <totem-dirs.h>

## Description

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

The functions in totem-dirs.h are used to allow plugins to find and load files installed alongside the plugins, such as UI files.

## Functions

### 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.

#### Parameters

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.

#### Parameters

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.

#### Parameters

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.

#### Parameters

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.

### 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.
