Issue: Hard coding fontpath to ucs-fonts

Note: I've set the fonts directory to be ucs-fonts--the fonts that Zutty was designed for. Zutty does not support searching for fonts using fontconfig and the author has rejected suggestions to support nix/guix or fontconfig instead scanning a hard coded fonts path, or relying on Xresources or command line options. An alternative approach would be to have override-able options for setting the font package and font name. I welcome other suggestions or advice.

From the zutty's author:

The author of Zutty prefers the so-called misc-fixed fonts. These are upgraded, extended versions of the bitmap fonts originally designed for the X Window System, created in the '80s in an era of much inferior computer displays. Their availability is universal; you probably have them installed already. These fonts are highly optimized for readability at low resolutions.

I see a downside in adding a dependency on fontconfig.
The problem is due to the idiosyncrasy of nix/guix -- hardly any other platform resembling unix is going to have this issue.

Closing because Zutty already has appropriate facilities allowing the user to set up where it should look for fonts.

Move the default.nix file to by-name/zu/zutty/package.nix

[quag]

Made the suggested changes. Thanks for teaching me about the new by-name/zu/zutty/package.nix approach.

Tired

[wegank]

I'd probably add a isNixOS ? true and set the path to /run/current-system/sw/share/X11/fonts accordingly.

[quag]

If we set the font path to /run/current-system/sw/share/X11/fonts, isn't there a risk that the ucs-fonts won't be installed, and zutty will fail to start as it can't find it's default font (9x18)?

I'm really not sure the right way to package zutty here. Perhaps make it so you can configure both the default font and the font path?
