We install a wrapper script around WindowMaker that prepends
/gnu/store/XXX-windowmaker-XXX/bin to $PATH.  This setting is propagated
to all subprocesses in the entire X session, which is suboptimal.  It
would be nice to find another solution, preferably by using absolute
pathnames when launching subprocesses run by WindowMaker.

Fixed in be05e64.

The fix may have resulted in unintended side-effects.  On a fresh
installation of the System Distribution v0.8.1 WindowMaker is installed
by default, but it is not completely functional.

For example, the attempt to change the style via the menu results in
this error to be displayed:

    Could not execute command:
        setstyle /gnu/store/...windowmaker.../share/WindowMaker/Styles/Black.style

Likewise, selecting "Configure Window Maker" from the right-click menu
results in this error:

    Could not execute command: exec WPrefs

The "setstyle" executable is located in
/gnu/store/...windowmaker.../bin/, but is not in the PATH.

Yes, the $out/bin of windowmaker is not in $PATH, and same for sawfish.

Instead of wrapping every executable of session-type, we can:

#1: Add the package to system profile ('packages').
  It's not clear to me how to do it now, until we have something
  like the NixOS's module system.

#2: Make SLiM use '/run/current-system/profile/share/xsessions' as
    session_dir.
  So simply add a package providing xsession file to 'packages' should
  make it available to SLiM.  And all DE and many window-managers provide
  xsession files already (eg: openbox, sawfish, xfce), we can patch
  the rest (eg: WindowMaker) to install one.

I would like to go #2, WDYT?

What I have in mind is to add a ‘packages’ field in ‘service’.  That
would allow service implementations to contribute packages to the global
profile.  Thoughts?

IIUC the bug initially reported here would remain: the user’s $PATH
would be polluted with the window manager’s stuff, no?

Thanks,

It's fine, but we may also need a 'dbus-service' field (for wicd).

I think the 'polluted' means we have a $PATH contains:
  /gnu/store/xxx-windowmaker/bin
install it to profile doesn't have this issue.

Hmm right.  And dbus policy, and policykit something, and...

Clearly the NixOS way where each service can change anything in the
global config makes it easy; we need to find a middle ground where we
don’t end up allowing services to do anything.  Food for thought...

Right, but WindowMaker is not necessarily in the user’s profile.

Still, maybe the initial solution, which added WindowMaker to $PATH, is
the least undesirable solution.

Thoughts?

And I cannot reproduce this.  I believe the fix Ludo did 6 years ago in
be05e643ae4d62dc25aa88b7fbdb0eae9cf10eb0 combined with the use of a
xsession file added in commit 537fe4568f4 by Kei resolved this issue for
good.

Closing.

Thanks,

Maxim
