============
|

|
| 15 |
*APP*
|
| 16 |
A graphical application that should be listed in the menus.
|
| 17 |
*WM*
|
| 18 |
A program containing a menu manager (i.e. a program that can display a menu, e.g. a windowmanager).

Abstract
|
| 23 |
========
|
| 24 |
|
| 25 |
This GLEP handles a proposal for the following two goals:
|
| 26 |
|
| 27 |
* Create a common menu layout, which would be independent of the WM.
|
| 28 |
This point is quite important for those people who use more than one WM.
|
| 29 |
* Provide a common way to add applications to the menus.
|
| 30 |
|
| 31 |
|
| 32 |
|
| 33 |
Motivation
|
| 34 |
==========
|
| 35 |
|
| 36 |
GNOME, KDE, Fluxbox, to name only a few, have all their own ways of handling
|
| 37 |
menus. There have been several requests [1]_ [2]_ [3]_ [4]_ [5]_ [6]_ from
|
| 38 |
users to streamline these menus. Furthermore there are several bug reports
|
| 39 |
about applications not having a menu entry [7]_, but since there is not
|
| 40 |
standard way to create such an entry, they are just sitting around in
|
| 41 |
bugzilla.
|
| 42 |
|
| 43 |
|
| 44 |
|
| 45 |
Rationale
|
| 46 |
=========
|
| 47 |
|
| 48 |
The idea of a common menu system is not new to the Linux world, every big
|
| 49 |
distribution (Debian, Mandrake, RedHat, Suse) has such a system. The big DE's,
|
| 50 |
KDE and GNOME, with the help of freedesktop.org [8]_, are also trying to
|
| 51 |
implement one standard. That will most likely happen in GNOME 2.6 and KDE 3.2
|
| 52 |
(Currently they are only implementing different versions of the
|
| 53 |
desktop-entry-spec, but interpreting it in an incompatible way). But there
|
| 54 |
are still many other WM's that currently don't support these specs. So we are
|
| 55 |
trying to base our work on the specifications GNOME and KDE are going to use.
|
| 56 |
(These are no official standards but evolving specifications). This has the
|
| 57 |
following advantages:
|
| 58 |
|
| 59 |
* follow specified standards
|
| 60 |
* i18n support
|
| 61 |
* provide the necessary flexibility and modularity
|
| 62 |
* integrate with small changes to our ebuildtree.
|
| 63 |
* support for per system and per user menus
|
| 64 |
|
| 65 |
|
| 66 |
|
| 67 |
Specification
|
| 68 |
=============
|
| 69 |
|
| 70 |
We are trying to follow these specifications:
|
| 71 |
|
| 72 |
* Desktop Entry Specification [9]_
|
| 73 |
* Menu Specification [10]_
|
| 74 |
* Icon Theme Specification [11]_
|
| 75 |
|
| 76 |
There are two libraries that offer an API to these specifications:
|
| 77 |
|
| 78 |
* PyXDG [12]_ (written in python)
|
| 79 |
* Desktop File Utils [13]_ (written in C)
|
| 80 |
|
| 81 |
Our goal is to patch the WM's with the help of these libraries to support the
|
| 82 |
specifications. APP's then only have to install a .desktop entry [9]_ and
|
| 83 |
optionally an icon and will be listed in all menus. This installation could
|
| 84 |
easily be done by two portage commands (domenu, doicon).
|
| 85 |
|
| 86 |
|
| 87 |
Implementation / Status
|
| 88 |
=======================
|
| 89 |
|
| 90 |
This GLEP exists for a long time now, still it is not accepted. I will outline
|
| 91 |
the current status:
|
| 92 |
|
| 93 |
* KDE 3.2 (x86) supports this specification
|
| 94 |
* GNOME 2.6 (~x86) support this specification
|
| 95 |
* domenu[12_] has to be included in portage to be used by the ebuilds to
|
| 96 |
install a desktop entry
|
| 97 |
* Somebody needs to write patches for the other WM's:
|
| 98 |
|
| 99 |
We should focus on adding support to the following WM's first:
|
| 100 |
|
| 101 |
* xfce, blackblox / fluxbox / openbox / waimea / kahakai, icewm
|
| 102 |
* fvwm, windowmaker, enlightment, afterstep
|
| 103 |
|
| 104 |
The following are not so important, but support some kind of applications
|
| 105 |
menu:
|
| 106 |
|
| 107 |
* aewm / aewm++ / evilwm / windowlab / oroborus, amiwm, ctwm, flwm
|
| 108 |
* golem, larswm, pekwm, plwm, pwm, qvwm, selectwm, treewm, trwm
|
| 109 |
* vtwm, xpde
|
| 110 |
