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.

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
