Nix build

[colonelpanic8]

Similar request to #4, but for nix. I am actually working on this right now and almost done. Once done, getting travis working should be really simple.

I've fixed a ton of stuff, but am currently stuck on waymonad itself, getting:

src/Waymonad/Protocols/Background.hs:1:1: error:
    Exception when trying to run compile-time code:
      wayland-scanner: readCreateProcess: runInteractiveProcess: exec: does not exist2 (No such file or directory)
    Code: runScanner (protocolFromFile "protocols/background.xml")
            $ ScannerEnv
                $ M.fromList
                    [("wl_surface",
                      (TH.AppT (TH.ConT ''Ptr) (TH.ConT ''WlrSurface),
                       TH.VarE 'surfaceFromResource,
                       TH.LamE [TH.WildP] (TH.VarE 'getSurfaceResource))),
                     ("wl_output",
                      (TH.AppT (TH.ConT ''Ptr) (TH.ConT ''WlrOutput),
                       TH.VarE 'outputFromResource, TH.VarE 'outputResourceForClient))]

Any idea what this might be coming from?

[colonelpanic8]

Seems like this is coming from this line:

https://github.com/waymonad/waymonad-scanner/blob/91f184e390aeb542eb3ccecabc848e9baea7162c/src/Graphics/Wayland/Scanner.hs#L51

the weird thing is that waymonad-scanner doesn't seem to have an associated executable, so I'm a little bit confused about where this executable is supposed to be coming from.

travis build works here:

https://travis-ci.org/IvanMalison/waymonad

[puffnfresh]

@IvanMalison looks like that's part of the Wayland library build:

https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/wayland/default.nix#L3

I guess it's disabled by default 😢

[colonelpanic8]

@puffnfresh yeah I figured that out. The nix build works now (see #42)

[xaverdh]

Thanks for getting this working @IvanMalison. I too looked into building this with nix some time ago, but couldn't make it work.

[colonelpanic8]

@xaverdh Were you able to get it to build? nix-build should just work with this PR. I would love it if someone else could build and actually see if they get it working. I cant get the binary to do anything useful except show a mouse pointer

[xaverdh]

Not quite, I get the following

error: anonymous function at /nix/store/x7wxji51hbi990jilb5fz5ii1mszjiv7-cabal2nix-libinput/default.nix:1:1 
called with unexpected argument 'libinput',
at /nix/store/fwjz2jvv2fmj8c0534fklfrcdc9qdy3x-source/pkgs/development/haskell-modules/make-package-set.nix:87:27

[xaverdh]

Adding PkgConfig-Depends: libinput to the cabal file of libinput in hsroots/libinput/ made it compile (it did take some time though, because it had to rebuild glibc-2.27).

[colonelpanic8]

@xaverdh as mentioned in the pull request:

This depends on swaywm/hsroots#7, which, in turn, depends on waymonad/libinput#1

[xaverdh]

Ah sorry, overlooked that. Well I guess it works then :-)

[colonelpanic8]

@xaverdh Were you able to actually run it and do things with it. I just get a gray screen and none of the keybindings seem to work.

[colonelpanic8]

@Ongy Would love some help.

[willat8]

Check out Ongy's waymonad-config https://github.com/Ongy/waymonad-config
Default modifier key is super instead of alt, with super+return launching urxvt https://github.com/Ongy/waymonad-config/blob/master/lap/Main.hs#L173 (which can be changed to gnome-terminal or similar for a wayland-native option).

[colonelpanic8]

@willat I tried both super and alt

[xaverdh]

Actually I can't get it to run yet. How do you usually run the binary?
I tried exec'ing from a tty. That didn't work, because it needed CAP_SYS_ADMIN for something. After launching with that capability it couldn't find egl drivers.
Im on NixOS btw.

I tried this:
https://github.com/ivanmalison/dotfiles/blob/f2887c9a281ccd70de5771676fcf4f30fee3ae86/nixos/configuration.nix#L339

but it didn't really work. Maybe it needs to be run not as a windowmanager but as a desktop environment.

[xaverdh]

Ok, no matter what I do, I can't get it to find the EGL drivers. Very likely that is nixpkgs/nixos related.
@IvanMalison you are also on nixos though, but don't have any problem with EGL, right?
Whats your driver setup and what channel are you using?
Im on unstable (nixos-19.09pre185176.1036dc66416) and using intel graphics.

[colonelpanic8]

@xaverdh I'm using nvidia graphics. You get a runtime issue?

[xaverdh]

Yes, logs look like this:

[xaverdh]

Maybe building from a pinned commit is not a good idea? The GL stuff is rather impure, so maybe the problem is that I build against a version different from the one my system configuration is based on?
Anyway I tried building from newer nixpkgs and ran into this issue

[DieracDelta]

Did this ever get resolved? @xaverdh did you ever get this successfully building?

[xaverdh]

I could not get it building unfortunately :-(
You would have to fix swaywm/hsroots#5 first. I am not too familiar with either the code or the technical details of wayland, so I gave up on it for the moment.
