DESCRIPTION
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.

METHODS

  bookmarkfile = Glib::BookmarkFile->new

  $bookmark_file->add_application ($uri, $name, $exec)

•   $uri (string)

•   $name (string or undef)

•   $exec (string or undef)

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 "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.

  $bookmark_file->add_group ($uri, $group)

•   $uri (string)

•   $group (string)

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.

  unix timestamp = $bookmark_file->get_added ($uri)

•   $uri (string)

  $bookmark_file->set_added ($uri, $value)

•   $uri (string)

•   $value (unix timestamp)

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

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

•   $uri (string)

•   $name (string)

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

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

  $bookmark_file->set_app_info ($uri, $name, $exec, $count, $stamp)

•   $uri (string)

•   $name (string)

•   $exec (string)

•   $count (integer)

•   $stamp (unix timestamp)

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.
