Re: [Nix-dev] Sway window manager nix package

Hi Chris,

For a symlink from the nix store into /etc you would need to use writeText
to write a file with the contents (I'm assuming empty string) and then use
environment.etc to link that file into /etc; however this would be
immutable and swaylock would not be able to modify this file if done this
way. I would expect a lock file to be created by the application at
runtime, and /etc/pam.d seems like an odd place for a lock file to me.

To change the sway version on build, there's a VERSION parameter in the
cmakelists file in the source repo. I'm not familiar with CMAKE, but if you
figure out how to set that option on the command line, you could change the
buildPhase to call cmake with that variable set instead. I'm guessing the
1970 thing is because it's getting the date modified for the binary and all
nix binaries for reproducibility in the store are set to 0 seconds after
the epoch for the date.

Thanks,

Sam

[Nix-dev] Sway window manager nix package

2017-07-10 Thread Chris Duncan via nix-dev
Hello,

I have recently started using NixOS 17.03 and am having fun getting to know
it. I use the Sway window manager and wanted to make some changes to the
current nix package.

I managed to upgrade to version 0.13.0 of Sway and build the swaylock
application by including pam as a build input. There are two remaining
issues that I am not sure how to solve:

1. swaylock did not recognise the password to unlock the screen. This was
because there was no swaylock file created in the /etc/pam.d folder. When I
created this file manually swaylock worked as I expected. Could anybody
help me to understand what I need to do to get this file created during
package installation?

2. When I display the Sway version with sway --version it returns 'sway
version  (1970-01-01, branch "")'. The difference between this output and
that returned by the package already in nixpkgs is the date. Could anybody
tell me how I can get a sensible date to show up in the version output?

Any help with the above issues would be much appreciated. Please let me
know if any further information is required.

*Regards,*
