Description

TotemPlParser is a general-purpose playlist parser and writer, with support for several different types of playlist. Note that totem-pl-parser requires a main loop to operate properly (e.g. for the "entry-parsed" signal to be emitted).

Example 1. Reading a Playlist

TotemPlParser *pl = totem_pl_parser_new ();
g_object_set (pl, "recurse", FALSE, "disable-unsafe", TRUE, NULL);
g_signal_connect (G_OBJECT (pl), "playlist-started", G_CALLBACK (playlist_started), NULL);
g_signal_connect (G_OBJECT (pl), "entry-parsed", G_CALLBACK (entry_parsed), NULL);

if (totem_pl_parser_parse (pl, "http://example.com/playlist.pls", FALSE) != TOTEM_PL_PARSER_RESULT_SUCCESS)
    g_error ("Playlist parsing failed.");

g_object_unref (pl);

Example 2. Reading a Playlist Asynchronously

TotemPlParser *pl = totem_pl_parser_new ();
g_object_set (pl, "recurse", FALSE, "disable-unsafe", TRUE, NULL);
g_signal_connect (G_OBJECT (pl), "playlist-started", G_CALLBACK (playlist_started), NULL);
g_signal_connect (G_OBJECT (pl), "entry-parsed", G_CALLBACK (entry_parsed), NULL);

totem_pl_parser_parse_async (pl, "http://example.com/playlist.pls", FALSE, NULL, parse_cb, NULL);
g_object_unref (pl);

static void
parse_cb (TotemPlParser *parser, GAsyncResult *result, gpointer user_data)
{
GError *error = NULL;
    if (totem_pl_parser_parse_finish (parser, result, &error) != TOTEM_PL_PARSER_RESULT_SUCCESS) {
        g_error ("Playlist parsing failed: %s", error->message);
        g_error_free (error);
    }
}

Example 3. Getting Metadata from Entries

static void
entry_parsed (TotemPlParser *parser, const gchar *uri, GHashTable *metadata, gpointer user_data)
{
    gchar *title = g_hash_table_lookup (metadata, TOTEM_PL_PARSER_FIELD_TITLE);
    if (title != NULL)
        g_message ("Entry title: %s", title);
    else
        g_message ("Entry (URI: %s) has no title.", uri);
}

Example 4. Writing a Playlist

{
    TotemPlParser *pl;
    TotemPlPlaylist *playlist;
    TotemPlPlaylistIter iter;
    GFile *file;

    pl = totem_pl_parser_new ();
    playlist = totem_pl_playlist_new ();
    file = g_file_new_for_path ("/tmp/playlist.pls");

    totem_pl_playlist_append (playlist, &iter);
    totem_pl_playlist_set (playlist, &iter,
                   TOTEM_PL_PARSER_FIELD_URI, "file:///1.ogg",
                   TOTEM_PL_PARSER_FIELD_TITLE, "1.ogg",
                   NULL);

    totem_pl_playlist_append (playlist, &iter);
    totem_pl_playlist_set (playlist, &iter,
                   TOTEM_PL_PARSER_FIELD_URI, "file:///2.ogg",
                   NULL);

    if (totem_pl_parser_save (pl, playlist, file, "Title",
                  TOTEM_PL_PARSER_PLS, NULL) != TRUE) {
        g_error ("Playlist writing failed.");
    }

    g_object_unref (playlist);
    g_object_unref (pl);
    g_object_unref (file);
}

Details

TotemPlParser

typedef struct _TotemPlParser TotemPlParser;

All the fields in the TotemPlParser structure are private and should never be accessed directly.

TotemPlParserClass

typedef struct {
	GObjectClass parent_class;

	/* signals */
	void (*entry_parsed) (TotemPlParser *parser,
			      const char *uri,
			      GHashTable *metadata);
	void (*playlist_started) (TotemPlParser *parser,
				  const char *uri,
				  GHashTable *metadata);
	void (*playlist_ended) (TotemPlParser *parser,
				const char *uri);
} TotemPlParserClass;

The class structure for the TotemPlParser type.

GObjectClass `parent_class`;	the parent class
`entry_parsed` ()	the generic signal handler for the "entry-parsed" signal, which can be overridden by inheriting classes
`playlist_started` ()	the generic signal handler for the "playlist-started" signal, which can be overridden by inheriting classes
`playlist_ended` ()	the generic signal handler for the "playlist-ended" signal, which can be overridden by inheriting classes

enum TotemPlParserResult

typedef enum {
	TOTEM_PL_PARSER_RESULT_UNHANDLED,
	TOTEM_PL_PARSER_RESULT_ERROR,
	TOTEM_PL_PARSER_RESULT_SUCCESS,
	TOTEM_PL_PARSER_RESULT_IGNORED,
	TOTEM_PL_PARSER_RESULT_CANCELLED
} TotemPlParserResult;

Gives the result of parsing a playlist.

`TOTEM_PL_PARSER_RESULT_UNHANDLED`	The playlist could not be handled.
`TOTEM_PL_PARSER_RESULT_ERROR`	There was an error parsing the playlist.
`TOTEM_PL_PARSER_RESULT_SUCCESS`	The playlist was parsed successfully.
`TOTEM_PL_PARSER_RESULT_IGNORED`	The playlist was ignored due to its scheme or MIME type (see `totem_pl_parser_add_ignored_scheme()` and `totem_pl_parser_add_ignored_mimetype()`).
`TOTEM_PL_PARSER_RESULT_CANCELLED`	Parsing of the playlist was cancelled part-way through.

enum TotemPlParserType

typedef enum {
	TOTEM_PL_PARSER_PLS,
	TOTEM_PL_PARSER_M3U,
	TOTEM_PL_PARSER_M3U_DOS,
	TOTEM_PL_PARSER_XSPF,
	TOTEM_PL_PARSER_IRIVER_PLA,
} TotemPlParserType;

The type of playlist a TotemPlParser will parse.

`TOTEM_PL_PARSER_PLS`	PLS parser
`TOTEM_PL_PARSER_M3U`	M3U parser
`TOTEM_PL_PARSER_M3U_DOS`	M3U (DOS linebreaks) parser
`TOTEM_PL_PARSER_XSPF`	XSPF parser
`TOTEM_PL_PARSER_IRIVER_PLA`	iRiver PLA parser

enum TotemPlParserError

typedef enum {
	TOTEM_PL_PARSER_ERROR_NO_DISC,
	TOTEM_PL_PARSER_ERROR_MOUNT_FAILED,
	TOTEM_PL_PARSER_ERROR_EMPTY_PLAYLIST
} TotemPlParserError;

Allows you to differentiate between different errors occurring during file operations in a TotemPlParser.

`TOTEM_PL_PARSER_ERROR_NO_DISC`	Error attempting to open a disc device when no disc is present
`TOTEM_PL_PARSER_ERROR_MOUNT_FAILED`	An attempted mount operation failed
`TOTEM_PL_PARSER_ERROR_EMPTY_PLAYLIST`	Playlist to be saved is empty

TotemPlParserMetadata

typedef GHashTable TotemPlParserMetadata;

An alias for GHashTable, used in the "entry-parsed" and "playlist-started" signals due to GHashTable not being a boxed type when totem-pl-parser was originally written.

The hash table is a mapping from field names (such as TOTEM_PL_PARSER_FIELD_ALBUM) to their associated values.

It is safe to use GHashTable instead of TotemPlParserMetadata everywhere.

totem_pl_parser_new ()

TotemPlParser *     totem_pl_parser_new                 (void);

Creates a TotemPlParser object.

Returns :

a new TotemPlParser

totem_pl_parser_parse ()

TotemPlParserResult totem_pl_parser_parse               (TotemPlParser *parser,
                                                         const char *uri,
                                                         gboolean fallback);

Parses a playlist given by the absolute URI uri. This method is synchronous, and will block on (e.g.) network requests to slow servers. totem_pl_parser_parse_async() is recommended instead.

Return values are as totem_pl_parser_parse_with_base().

`parser` :	a TotemPlParser
`uri` :	the URI of the playlist to parse
`fallback` :	`TRUE` if the parser should add the playlist URI to the end of the playlist on parse failure
Returns :	a TotemPlParserResult

totem_pl_parser_parse_async ()

void                totem_pl_parser_parse_async         (TotemPlParser *parser,
                                                         const char *uri,
                                                         gboolean fallback,
                                                         GCancellable *cancellable,
                                                         GAsyncReadyCallback callback,
                                                         gpointer user_data);

Starts asynchronous parsing of a playlist given by the absolute URI uri. parser and uri are both reffed/copied when this function is called, so can safely be freed after this function returns.

For more details, see totem_pl_parser_parse(), which is the synchronous version of this function.

When the operation is finished, callback will be called. You can then call totem_pl_parser_parse_finish() to get the results of the operation.

`parser` :	a TotemPlParser
`uri` :	the URI of the playlist to parse
`fallback` :	`TRUE` if the parser should add the playlist URI to the end of the playlist on parse failure
`cancellable` :	optional GCancellable object, or `NULL`. [allow-none]
`callback` :	a GAsyncReadyCallback to call when parsing is finished. [allow-none]
`user_data` :	data to pass to the `callback` function

totem_pl_parser_parse_finish ()

TotemPlParserResult totem_pl_parser_parse_finish        (TotemPlParser *parser,
                                                         GAsyncResult *async_result,
                                                         GError **error);

Finishes an asynchronous playlist parsing operation started with totem_pl_parser_parse_async() or totem_pl_parser_parse_with_base_async().

If parsing of the playlist is cancelled part-way through, TOTEM_PL_PARSER_RESULT_CANCELLED is returned when this function is called.

`parser` :	a TotemPlParser
`async_result` :	a GAsyncResult
`error` :	a GError, or `NULL`
Returns :	a TotemPlParserResult

totem_pl_parser_parse_with_base ()

TotemPlParserResult totem_pl_parser_parse_with_base     (TotemPlParser *parser,
                                                         const char *uri,
                                                         const char *base,
                                                         gboolean fallback);

Parses a playlist given by the absolute URI uri, using base to resolve relative paths where appropriate.

`parser` :	a TotemPlParser
`uri` :	the URI of the playlist to parse
`base` :	the base path for relative filenames, or `NULL`. [allow-none]
`fallback` :	`TRUE` if the parser should add the playlist URI to the end of the playlist on parse failure
Returns :	a TotemPlParserResult

totem_pl_parser_parse_with_base_async ()

void                totem_pl_parser_parse_with_base_async
                                                        (TotemPlParser *parser,

Starts asynchronous parsing of a playlist given by the absolute URI uri, using base to resolve relative paths where appropriate. parser and uri are both reffed/copied when this function is called, so can safely be freed after this function returns.

For more details, see totem_pl_parser_parse_with_base(), which is the synchronous version of this function.

When the operation is finished, callback will be called. You can then call totem_pl_parser_parse_finish() to get the results of the operation.

`parser` :	a TotemPlParser
`uri` :	the URI of the playlist to parse
`base` :	the base path for relative filenames, or `NULL`. [allow-none]
`fallback` :	`TRUE` if the parser should add the playlist URI to the end of the playlist on parse failure
`cancellable` :	optional GCancellable object, or `NULL`. [allow-none]
`callback` :	a GAsyncReadyCallback to call when parsing is finished. [allow-none]
`user_data` :	data to pass to the `callback` function

                                                         GError **error);

Writes the playlist held by parser and playlist out to the path pointed by dest. The playlist is written in the format type and is given the title title.

If the output file is a directory the G_IO_ERROR_IS_DIRECTORY error will be returned, and if the file is some other form of non-regular file then a G_IO_ERROR_NOT_REGULAR_FILE error will be returned. Some file systems don't allow all file names, and may return a G_IO_ERROR_INVALID_FILENAME error, and if the name is too long, G_IO_ERROR_FILENAME_TOO_LONG will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

In extreme cases, a G_IO_ERROR_INVALID_ARGUMENT error can be returned, if parts of the playlist to be written are too long.

If writing a PLA playlist and there is an error converting a URI's encoding, a code from GConvertError will be returned.

`parser` :	a TotemPlParser
`playlist` :	a TotemPlPlaylist
`dest` :	output GFile
`title` :	the playlist title
`type` :	a TotemPlParserType for the outputted playlist
`error` :	return loction for a GError, or `NULL`
Returns :	`TRUE` on success

Default value: FALSE

The `"force"` property

  "force"                    gboolean              : Read / Write

If TRUE, the parser will attempt to parse a playlist, even if it appears to be unsupported (usually because of its filename extension).
