[PATCH 00/13] Add xmonad, xmonad-contrib and dependencies.

[PATCH 00/13] Add xmonad, xmonad-contrib and dependencies.

[Siniša Biđin]

Hi,

I've attached packages for xmonad and xmonad-contrib, alongside a series of
their (direct or not) ghc-* dependencies. Most of the stuff went into
haskell.scm, but I've singled out xmonad{,-contrib} into their own module.

Any feedback appreciated.

Siniša Biđin (13):
  gnu: Add ghc-data-default-class.
  gnu: Add ghc-data-default-instances-base.
  gnu: Add ghc-data-default-instances-containers.
  gnu: Add ghc-data-default-instances-old-locale.
  gnu: Add ghc-dlist.
  gnu: Add ghc-extensible-exceptions.
  gnu: Add ghc-data-default-instances-dlist.

I had to replace "Exec=/etc/X11/Session/xmonad" with "Exec=xmonad"
in this xmonad.desktop file in order to launch an xmonad session from
Slim.  Does this seem right?  Does it make sense to fetch this file
from gentoo.org and then modify it? or should we rather just generate it
ourselves?  What do you/others think?

Do these inputs need to be propagated?  I can start up an xmonad
session without propagating these inputs.  Do they need to be available
for xmonad's 'mod-q' (i.e. restarting xmonad/loading a new config)?

Definitely!

I didn't test it thoroughly enough: I've been running xmonad via an
xsession file and managed to accidentally avoid the issue.

I had followed ratpoison's example (also using gentoo.org), but it does
feel dirty. I'm fine with generating it or having it stored in guix's 
repo,
but couldn't find an example of any other package doing the same.

I think so, yes. For one, since xmonad is an executable and a library, 
if
we don't propagate, "ghc-pkg list" will report it as broken. Manually
calling "ghc --make" on xmonad.hs (or other modules using XMonad) will
fail, and I'm assuming mod-q will also (but I confess I haven't tested:
I felt avoiding a broken package in ghc's package database was enough of
a reason for propagating the dependencies).

I think “generating” it (or having it as a string literal) in the source
is preferable.

Makes sense to me.

Could you post an updated patch that addresses these two things?

TIA, and sorry for the delay!

BTW, attached is the current state of the patch that I have.  It
addresses the first item here (installing the xsession file).

For the second, I was toying with the idea of wrapping the xmonad
executable to provide both the ghc binary and the needed modules
(transitive propagated inputs, similar in style to what's done with
git-email currently, and for which I have an outstanding patch).  The
intent, IMO, would be to support xmonad's "reconfiguration".  I've not
used xmonad much before, but this appears to involve basically a
rebuild of the xmonad binary.  I'm not sure that just propagating the
input modules would be enough to support this.  It's also somewhat
unfortunate that the build would happen in a relatively polluted
environment.  Anyhow, sharing my current patch in case anyone else
wanted to play with it.

I've pushed a modified commit that generates the .desktop files for
xmonad, and adds the package instead to gnu/packages/wm.scm.

This Xmonad's mod-q does not work as expected, but that isn't a problem
if you like the default configuration ;).  Anyhow, some more work will
need to be done to support reconfiguration.  I had thought
GHC_PACKAGE_PATH would do what we need, but it doesn't seem to do what
I had thought.  Perhaps creating a custom package database for xmonad
to use would work.

Thanks again for the patch, and sorry for the delay in getting it
pushed!

I believe mod-q works fine for me with the following set:

     profile=$HOME/.guix-profile
     export GHC_PACKAGE_PATH=$profile/lib/ghc-7.8.4/package.conf.d/:

Note the trailing colon. (I haven't yet tried this out with the new
version you just pushed, so it's very possible this doesn't help.)

About creating custom package databases: my xmonad.hs imports packages
other than xmonad and xmonad-contrib, so my GHC_PACKAGE_PATH would in
that case still need to contain the $profile's package database.
