## Description

GBookmarkFile lets you parse, edit or create files containing bookmarks to URI, along with some meta-data about the resource pointed by the URI like its MIME type, the application that is registering the bookmark and the icon that should be used to represent the bookmark. The data is stored using the Desktop Bookmark Specification.

The syntax of the bookmark files is described in detail inside the Desktop Bookmark Specification, here is a quick summary: bookmark files use a sub-class of the XML Bookmark Exchange Language specification, consisting of valid UTF-8 encoded XML, under the `xbel` root element; each bookmark is stored inside a `bookmark` element, using its URI: no relative paths can be used inside a bookmark file. The bookmark may have a user defined title and description, to be used instead of the URI. Under the `metadata` element, with its `owner` attribute set to `http://freedesktop.org`, is stored the meta-data about a resource pointed by its URI. The meta-data consists of the resource's MIME type; the applications that have registered a bookmark; the groups to which a bookmark belongs to; a visibility flag, used to set the bookmark as "private" to the applications and groups that has it registered; the URI and MIME type of an icon, to be used when displaying the bookmark inside a GUI.

A bookmark file might contain more than one bookmark; each bookmark is accessed through its URI.

The important caveat of bookmark files is that when you add a new bookmark you must also add the application that is registering it, using `g_bookmark_file_add_application()` or `g_bookmark_file_set_app_info()`. If a bookmark has no applications then it won't be dumped when creating the on disk representation, using `g_bookmark_file_to_data()` or `g_bookmark_file_to_file()`.

The GBookmarkFile parser was added in GLib 2.12.

## Details

### GBookmarkFile

    typedef struct _GBookmarkFile GBookmarkFile;

The GBookmarkFile struct contains only private data and should not be used directly.

### G_BOOKMARK_FILE_ERROR

    #define G_BOOKMARK_FILE_ERROR (g_bookmark_file_error_quark ())

Error domain for bookmark file parsing. Errors in this domain will be from the GBookmarkFileError enumeration. See GError for informations on error domains.

### enum GBookmarkFileError

    typedef enum
    {
      G_BOOKMARK_FILE_ERROR_INVALID_URI,
      G_BOOKMARK_FILE_ERROR_INVALID_VALUE,
      G_BOOKMARK_FILE_ERROR_APP_NOT_REGISTERED,
      G_BOOKMARK_FILE_ERROR_URI_NOT_FOUND,
      G_BOOKMARK_FILE_ERROR_READ,

      G_BOOKMARK_FILE_ERROR_WRITE,
      G_BOOKMARK_FILE_ERROR_FILE_NOT_FOUND

In the event that no application with name `app_name` has registered a bookmark for `uri`, `FALSE` is returned and error is set to G_BOOKMARK_FILE_ERROR_APP_NOT_REGISTERED. In the event that unquoting the command line fails, an error of the G_SHELL_ERROR domain is set and `FALSE` is returned.

Sets the last time the bookmark for `uri` was last modified.

If no bookmark for `uri` is found then it is created.

The "modified" time should only be set when the bookmark's meta-data was actually changed. Every function of GBookmarkFile that modifies a bookmark also changes the modification time, except for `g_bookmark_file_set_visited()`.

Sets the time the bookmark for `uri` was last visited.

If no bookmark for `uri` is found then it is created.

The "visited" time should only be set if the bookmark was launched, either using the command line retrieved by `g_bookmark_file_get_app_info()` or by the default application for the bookmark's MIME type, retrieved using `g_bookmark_file_get_mime_type()`. Changing the "visited" time does not affect the "modified" time.

### g_bookmark_file_set_app_info ()

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

You should rarely use this function; use `g_bookmark_file_add_application()` and `g_bookmark_file_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 `g_bookmark_file_get_app_info()` function. `count` is the number of times the application has registered the bookmark; if is < 0, the current registration count will be increased by one, if is 0, the application with `name` will be removed from the list of registered applications. `stamp` is the Unix time of the last registration; 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 `error` is set to G_BOOKMARK_FILE_ERROR_URI_NOT_FOUND; similarly, in the event that no application `name` has registered a bookmark for `uri`, `FALSE` is returned and error is set to G_BOOKMARK_FILE_ERROR_APP_NOT_REGISTERED. Otherwise, if no bookmark for `uri` is found, one is created.

`bookmark` : | a GBookmarkFile
`uri` : | a valid URI
`name` : | an application's name
`exec` : | an application's command line
`count` : | the number of registrations done for this application
`stamp` : | the time of the last registration for this application
`error` : | return location for a GError or `NULL`
Returns : | `TRUE` if the application's meta-data was successfully changed.

Adds `group` to the list of groups to which the bookmark for `uri` belongs to.

If no bookmark for `uri` is found then it is created.

`bookmark` : | a GBookmarkFile
`uri` : | a valid URI
`group` : | the group name to be added

### g_bookmark_file_add_application ()

                                                             const gchar *exec);

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

Every bookmark inside a GBookmarkFile 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 `NULL`, the name of the application will be the same returned by `g_get_application_name()`; if `exec` is `NULL`, the command line will be a composition of the program name as returned by `g_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 `bookmark`.

If no bookmark for `uri` is found, one is created.

`bookmark` : | a GBookmarkFile
`uri` : | a valid URI
`name` : | the name of the application registering the bookmark or `NULL`
`exec` : | command line to be used to launch the bookmark or `NULL`

Removes `group` from the list of groups to which the bookmark for `uri` belongs to.

In the event the URI cannot be found, `FALSE` is returned and `error` is set to G_BOOKMARK_FILE_ERROR_URI_NOT_FOUND. In the event no group was defined, `FALSE` is returned and `error` is set to G_BOOKMARK_FILE_ERROR_INVALID_VALUE.

`bookmark` : | a GBookmarkFile
`uri` : | a valid URI
`group` : | the group name to be removed
`error` : | return location for a GError, or `NULL`

Removes application registered with `name` from the list of applications that have registered a bookmark for `uri` inside `bookmark`.

In the event the URI cannot be found, `FALSE` is returned and `error` is set to G_BOOKMARK_FILE_ERROR_URI_NOT_FOUND. In the event that no application with name `app_name` has registered a bookmark for `uri`, `FALSE` is returned and error is set to G_BOOKMARK_FILE_ERROR_APP_NOT_REGISTERED.

`bookmark` : | a GBookmarkFile
