(s) desktop-file(s)

xdg-desktop-menu uninstall [--noupdate] [--mode mode] directory-file(s)

xdg-desktop-menu { --help | --manual | --version }

Description

The xdg-desktop-menu program can be used to install new menu entries to the
desktop's application menu.

The application menu works according to the XDG Desktop Menu Specification at
http://www.freedesktop.org/wiki/Specifications/menu-spec

Commands

install

    Install one or more applications in a submenu of the desktop menu system.

    desktop-file: A desktop file represents a single menu entry in the menu.
    Desktop files are defined by the freedesktop.org Desktop Entry
    Specification. The most important aspects of *.desktop files are summarized
    below.

    Menu entries can be added to the menu system in two different ways. They
    can either be added to a predefined submenu in the menu system based on one
    or more category keywords, or they can be added to a new submenu.

    To add a menu entry to a predefined submenu the desktop file that
    represents the menu entry must have a Categories= entry that lists one or
    more keywords. The menu item will be included in an appropriate submenu
    based on the included keywords.

    To add menu items to a new submenu the desktop-files must be preceded by a
    directory-file that describes the submenu. If multiple desktop-files are
    specified, all entries will be added to the same menu. If entries are
    installed to a menu that has been created with a previous call to 
    xdg-desktop-menu the entries will be installed in addition to any already
    existing entries.

    directory-file: The *.directory file indicated by directory-file represents
    a submenu. The directory file provides the name and icon for a submenu. The
    name of the directory file is used to identify the submenu.

    If multiple directory files are provided each file will represent a submenu
    within the menu that precedes it, creating a nested menu hierarchy
    (sub-sub-menus). The menu entries themselves will be added to the last
    submenu.

    Directory files follow the syntax defined by the freedesktop.org Desktop
    Entry Specification.

uninstall

    Remove applications or submenus from the desktop menu system previously
    installed with xdg-desktop-menu install.

    A submenu and the associated directory file is only removed when the
    submenu no longer contains any menu entries.

forceupdate

    Force an update of the menu system.

    This command is only useful if the last call to xdg-desktop-menu included
    the --noupdate option.

Options

--noupdate
    Postpone updating the menu system. If multiple updates to the menu system
    are made in sequence this flag can be used to indicate that additional
    changes will follow and that it is not necessary to update the menu system
    right away.
--novendor

    Normally, xdg-desktop-menu checks to ensure that any *.directory and
    *.desktop files to be installed has a vendor prefix. This option can be
    used to disable that check.

    A vendor prefix consists of alpha characters ([a-zA-Z]) and is terminated
    with a dash ("-"). Companies and organizations are encouraged to use a word
    or phrase, preferably the organizations name, for which they hold a
    trademark as their vendor prefix. The purpose of the vendor prefix is to
    prevent name conflicts.

--mode mode

    mode can be user or system. In user mode the file is (un)installed for the
    current user only. In system mode the file is (un)installed for all users
    on the system. Usually only root is allowed to install in system mode.

    The default is to use system mode when called by root and to use user mode
    when called by a non-root user.

--help
    Show command synopsis.
--manual
    Show this manual page.
--version
    Show the xdg-utils version information.

Desktop Files

An application item in the application menu is represented by a *.desktop file.
A *.desktop file consists of a [Desktop Entry] header followed by several Key=
Value lines.

A *.desktop file can provide a name and description for an application in
several different languages. This is done by adding a language code as used by
LC_MESSAGES in square brackets behind the Key. This way one can specify
different values for the same Key depending on the currently selected language.

The following keys are often used:

Type=Application
    This is a mandatory field that indicates that the *.desktop file describes
    an application launcher.
Name=Application Name
    The name of the application. For example Mozilla
GenericName=Generic Name
    A generic description of the application. For example Web Browser
Comment=Comment
    Optional field to specify a tooltip for the application. For example Visit
    websites on the Internet
Icon=Icon File
    The icon to use for the application. This can either be an absolute path to
    an image file or an icon-name. If an icon-name is provided an image lookup
    by name is done in the user's current icon theme. The xdg-icon-resource
    command can be used to install image files into icon themes. The advantage
    of using an icon-name instead of an absolute path is that with an icon-name
    the application icon can be provided in several different sizes as well as
    in several differently themed styles.
Exec=Command Line
    The command line to start the application. If the application can open
    files the %f placeholder should be specified. When a file is dropped on the
    application launcher the %f is replaced with the file path of the dropped
    file. If multiple files can be specified on the command line the %F
    placeholder should be used instead of %f. If the application is able to
    open URLs in addition to local files then %u or %U can be used instead of
    %f or %F.
Categories=Categories

    A list of categories separated by semi-colons. A category is a keyword that
    describes and classifies the application. By default applications are
    organized in the application menu based on category. When menu entries are
    explicitly assigned to a new submenu it is not necessary to list any
    categories.

    When using categories it is recommended to include one of the following
    categories: AudioVideo, Development, Education, Game, Graphics, Network,
    Office, Settings, System, Utility.

    See Appendix A of the XDG Desktop Menu Specification for information about
    additional categories: http://standards.freedesktop.org/menu-spec/
    menu-spec-1.0.html#category-registry

MimeType=Mimetypes
    A list of mimetypes separated by semi-colons. This field is used to
    indicate which file types the application is able to open.

For a complete overview of the *.desktop file format please visit http://
www.freedesktop.org/wiki/Specifications/desktop-entry-spec

Directory Files

The appearance of submenu in the application menu is provided by a *.directory
file. In particular it provides the title of the submenu and a possible icon. A
*.directory file consists of a [Desktop Entry] header followed by several Key=
Value lines.

A *.directory file can provide a title (name) for the submenu in several
different languages. This is done by adding a language code as used by
LC_MESSAGES in square brackets behind the Key. This way one can specify
different values for the same Key depending on the currently selected language.

The following keys are relevant for submenus:

Type=Directory
    This is a mandatory field that indicates that the *.directory file
    describes a submenu.
Name=Menu Name
    The title of submenu. For example Mozilla
Comment=Comment
    Optional field to specify a tooltip for the submenu.
Icon=Icon File
    The icon to use for the submenu. This can either be an absolute path to an
    image file or an icon-name. If an icon-name is provided an image lookup by
    name is done in the user's current icon theme. The xdg-icon-resource
    command can be used to install image files into icon themes. The advantage
    of using an icon-name instead of an absolute path is that with an icon-name
    the submenu icon can be provided in several different sizes as well as in
    several differently themed styles.

Environment Variables

xdg-desktop-menu honours the following environment variables:

XDG_UTILS_DEBUG_LEVEL
    Setting this environment variable to a non-zero numerical value makes
    xdg-desktop-menu do more verbose reporting on stderr. Setting a higher
    value increases the verbosity.
XDG_UTILS_INSTALL_MODE
    This environment variable can be used by the user or administrator to
    override the installation mode. Valid values are user and system.

Exit Codes

An exit code of 0 indicates success while a non-zero exit code indicates
failure. The following failure codes can be returned:

1
    Error in command line syntax.
2
    One of the files passed on the command line did not exist.
3
    A required tool could not be found.
4
    The action failed.
5
    No permission to read one of the files passed on the command line.

Examples

The company ShinyThings Inc. has developed an application named "WebMirror" and
would like to add it to the application menu. The company will use
"shinythings" as its vendor id. In order to add the application to the menu
there needs to be a .desktop file with a suitable Categories entry:

shinythings-webmirror.desktop:

  [Desktop Entry]
  Encoding=UTF-8
  Type=Application

  Exec=webmirror
  Icon=webmirror

  Name=WebMirror
  Name[nl]=WebSpiegel

  Categories=Network;WebDevelopment;

Now the xdg-desktop-menu tool can be used to add the
shinythings-webmirror.desktop file to the desktop application menu:

xdg-desktop-menu install ./shinythings-webmirror.desktop

Note that for the purpose of this example the menu items are available in two
languages, English and Dutch. The language code for Dutch is nl.

In the next example the company ShinyThings Inc. will add its own submenu to
the desktop application menu consisting of a "WebMirror" menu item and a
"WebMirror Admin Tool" menu item.

First the company needs to create two .desktop files that describe the two menu
items. Since the items are to be added to a new submenu it is not necessary to
include a Categories= line:

shinythings-webmirror.desktop:

  [Desktop Entry]
  Encoding=UTF-8
  Type=Application

  Exec=webmirror
  Icon=shinythings-webmirror

  Name=WebMirror
  Name[nl]=WebSpiegel


shinythings-webmirror-admin.desktop:

  [Desktop Entry]
  Encoding=UTF-8
  Type=Application

  Exec=webmirror-admintool
  Icon=shinythings-webmirror-admintool

  Name=WebMirror Admin Tool
  Name[nl]=WebSpiegel Administratie Tool

In addition a .directory file needs to be created to provide a title and icon
for the sub-menu itself:

shinythings-webmirror.directory:

  [Desktop Entry]
  Encoding=UTF-8

  Icon=shinythings-webmirror-menu

  Name=WebMirror
  Name[nl]=WebSpiegel

These file can now be installed with:

xdg-desktop-menu install ./shinythings-webmirror.directory \
      ./shinythings-webmirror.desktop ./shinythings-webmirror-admin.desktop

The menu entries could also be installed one by one:

xdg-desktop-menu install --noupdate ./shinythings-webmirror.directory \
      ./shinythings-webmirror.desktop
xdg-desktop-menu install --noupdate ./shinythings-webmirror.directory \
      ./shinythings-webmirror-admin.desktop
xdg-desktop-menu forceupdate

Although the result is the same it is slightly more efficient to install all
files at the same time.

The *.desktop and *.directory files reference icons with the names webmirror,
webmirror-admin and webmirror-menu which should also be installed. In this
example the icons are installed in two different sizes, once with a size of
22x22 pixels and once with a size of 64x64 pixels:

xdg-icon-resource install --size 22 ./wmicon-22.png shinythings-webmirror
xdg-icon-resource install --size 22 ./wmicon-menu-22.png shinythings-webmirror-menu
xdg-icon-resource install --size 22 ./wmicon-admin-22.png shinythings-webmirror-admin
xdg-icon-resource install --size 64 ./wmicon-64.png shinythings-webmirror
xdg-icon-resource install --size 64 ./wmicon-menu-64.png shinythings-webmirror-menu
xdg-icon-resource install --size 64 ./wmicon-admin-64.png shinythings-webmirror-admin
