Re: Suggest A debian-style menu system for guix

[Adonay Felipe Nogueira]

As some have noted, there are hooks to make FreeDesktop standard
.desktop files.

However, there is an important note: While this works well with GuixSD
users, it might make Guix users' host desktop not start correctly if,
for clarification, Guix advises the user to add the XDG_DATA_DIRS
variable to his "~/.profile" file as suggested by Guix, and if the user
follows the suggestion "to the teeth", see:
[[http://lists.gnu.org/archive/html/bug-guix/2017-03/msg00200.html]]
(and replies).

If a software component comes with desktop files, what's the right place
to put them relative to the component's output path?

I would imagine that a lot of desktop applications packaged with Guix
will probably come with desktop files.  Or, if they do not, I imagine
that we could add desktop files for them as we package them.  Instead of
requiring users to create their own desktop files individually (I can
never remember how to do it), it would be neat if desktop applications
installed via Guix came with desktop files installed in the "right
place" by default.  That way, any software which understands the
FreeDesktop standard would find the installed software and populate the
right menus automatically.

I think we're doing this already for some Guix packages, but since my
knowledge of the FreeDesktop standard is limited, I'm not sure if it's
by accident or if it's intentional.

Personally, I find .desktop files better suited for this. Place each of
them in "$HOME/.local/share/applications" directory.

More information about the FreeDesktop .desktop standard can be found
at:
[[https://specifications.freedesktop.org/desktop-entry-spec/latest/]].

As it evidences, GNOME has adapted a similar format, which can be read

Well, if there is no desktop file, wouldn't it be sufficient to add one?

Don't most/all WMs use .desktop files for this sort of thing?
The .desktop files are, if I recall correctly, also used to build menus.
If this is the case then I don't fully understand the point of
Debian's update-menu, shouldn't the XDG standard be used?

There is an extra spec used for extending .desktop files for menu use:

All I want to say is that:  we *must* add menu info in "package define"
if users of this package *real need* a menu instead of waiting upstream
to write a .desktop.

Thanks.

So what's the difference to existing menu-generators specific to many
or only a subset of window-managers, such as obconf?

Option 1: we could do this in scheme somehow, associated to Guix.
Option 2: we make this a choice (opt-in, run it on your own), not
an opt-out as coming up with a way where user menus are touched
is from my perspective a no-go.
I would not want some automatic generator to touch my menus which
are slightly different from just generated ones.

The below comment is from debian menu introduction.  if a package have a
debian menu file,  all window-manager's menu in debian will show this
package menu.

#+BEGIN_COMMENT
 Before the advent of update-menus, when the sysadmin installed a package onto 
a Debian system, they would need to edit various window manager config files to 
make the new program show up on, for example, fvwm's menus. The menus could 
easily become out of sync with what programs were actually available, with some 
menu items that didn't work, and other programs that lacked a menu entry. 
update-menus and Debian's menu package aim to solve this problem.

update-menus automatically generates menus of installed programs for window 
managers and other menu programs. It should be run whenever a menu file or 
menu-method file is changed. update-menus will be ran automatically when Debian 
packages that contain menu files are installed or removed from the system. 
Users themselves can add/delete menu items, and should then run update-menus as 
that user, thus creating window-manager startup files that are used in 
preference to the systemwide files.

Suggest A debian-style menu system for guix

[tumashu]

Debian menu system 
(https://www.debian.org/doc/packaging-manuals/menu.html/ch3.html) is a very 
useful tool,
is it possible develop a similar tool for guix?
