=for position DESCRIPTION

=head1 DESCRIPTION

B<Glib::BookmarkFile> lets you parse, edit or create files containing lists
of bookmarks to resources pointed to by URIs, with some meta-data bound to
them, following the Desktop Bookmark Specification.  The recent files support
inside GTK+ uses this type of files to store the list of recently used
files.

The syntax of bookmark files is described in detail in the Desktop Bookmarks
Specification, here is a quick summary: bookmark files use a subclass of the
XML Bookmark Exchange Language (XBEL) document format, defining meta-data
such as the MIME type of the resource pointed by a bookmark, the list of
applications that have registered the same URI and the visibility of the
bookmark.

=head1 METHODS

=head2 bookmarkfile = Glib::BookmarkFile-E<gt>B<new>

=over

=back

=head2 $bookmark_file-E<gt>B<add_application> ($uri, $name, $exec)

=over

=over

=item * $uri (string)

=item * $name (string or undef)

=item * $exec (string or undef)

=back

Adds the application with $name and $exec to the list of
applications that have registered a bookmark for $uri into
$bookmark_file.

Every bookmark inside a C<Glib::BookmarkFile> must have at least an
application registered.  Each application must provide a name, a
command line useful for launching the bookmark, the number of times
the bookmark has been registered by the application and the last
time the application registered this bookmark.

If $name is undef, the name of the application will be the
same returned by Glib::get_application_name(); if $exec is undef,
the command line will be a composition of the program name as
returned by Glib::get_prgname() and the "%u" modifier, which will
be expanded to the bookmark's URI.

This function will automatically take care of updating the
registrations count and timestamping in case an application
with the same $name had already registered a bookmark for
$uri inside the bookmark file.  If no bookmark for $uri is found
one is created.

=back

=head2 $bookmark_file-E<gt>B<add_group> ($uri, $group)

=over

=over

=item * $uri (string)

=item * $group (string)

=back

Adds $group to the list of groups to which the bookmark for $uri
belongs to.  If no bookmark for $uri is found one is created.

=back

=head2 unix timestamp = $bookmark_file-E<gt>B<get_added> ($uri)

=over

=over

=item * $uri (string)

=back

=for apidoc __gerror__
Gets the time the bookmark for $uri was added to $bookmark_file.

=back

=head2 Glib::BookmarkFile::set_added ($bookmark_file, $uri, $value)

=over

=over

=item * $bookmark_file (Glib::BookmarkFile)

=item * $uri (string)

=item * $value (unix timestamp)

=back

Sets the time the bookmark for $uri was added.
If no bookmark for $uri is found one is created.

=back

=head2 ($exec, $count, $stamp) = $bookmark_file->B<get_app_info> ($uri, $name)

=over

=over

=item * $uri (string)

=item * $name (string)

=back

Gets the registration informations of $name for the bookmark for
$uri.  See Glib::BookmarkFile::set_app_info() for more informations about
the returned data.

May croak with a L<Glib::Error> in $@ on failure.

=back

=head2 $bookmark_file-E<gt>B<set_app_info> ($uri, $name, $exec, $count, $stamp)

=over

=over

=item * $uri (string)

=item * $name (string)

=item * $exec (string)

=item * $count (integer)

=item * $stamp (unix timestamp)

=back

Sets the meta-data of application $name inside the list of
applications that have registered a bookmark for $uri inside
$bookmark_file.

You should rarely use this method; use Glib::BookmarkFile::add_application()
and Glib::BookmarkFile::remove_application() instead.

$name can be any UTF-8 encoded string used to identify an application.
$exec can have one of these two modifiers: "%f", which will be expanded
as the local file name retrieved from the bookmark's URI; "%u", which
will be expanded as the bookmark's URI. The expansion is done automatically
when retrieving the stored command line using the
Glib::BookmarkFile::get_app_info() method.
$count is the number of times the application has registered the
bookmark; if it is < 0, the current registration count will be increased
by one, if it is 0, the application with $name will be removed from
the list of registered applications.
$stamp is the Unix time of the last registration, as returned by time(); if
it is -1, the current time will be used.

If you try to remove an application by setting its registration count to
zero, and no bookmark for $uri is found, %FALSE is returned and an
exception is fired.

May croak with a L<Glib::Error> in $@ on failure.
