nix-installers VS ShellCheck

If you install it from the community RPM installer, it works as they have SELinux support added: https://github.com/nix-community/nix-installers

I tried to install the Nix package manager on my Fedora 37 machine. Having read about some issues with installing Nix with the install script on Fedora and other OS, using Selinux, I chose install via "nix-installers" rpm-packe (https://github.com/nix-community/nix-installers/issues/16). Unfortunately, I get warnings about created uids throughout the install process not being in the scope of `SYS_UID_MAX 999`. Furthermore, after rebooting the computer, I end up with a flickering black screen instead of on my (Gnome) Desktop environment.

Looks like you already found u/adisbladis legacy installers and opened a feature request for Silverblue support. Your best bet would be to start learning how SELinux policies work and see if you can adapt those for the way that you've set up Silverblue, or to see if you can modify the RPM builder to accommodate Silverblue by putting the Nix store under /var and bind mounting it onto /nix, like those other instructions floating around do.

There's work to add nix to silverblue via community packaging: https://github.com/nix-community/nix-installers/pull/8

I think nonguix also uses equivalent machinery for its Steam package: https://gitlab.com/nonguix/nonguix/-/blob/master/nongnu/pack...

Maybe there are docs on repurposing that someone more familiar with nonguix can point to.

Apparently there is an rpm-ostree-friendly RPM build of Nix that can be used to install Nix on Silverblue as well: https://github.com/nix-community/nix-installers/pull/8

It includes some code to get around the group/user management quirks that some other commenters have noted b0rked the Guix installer, so perhaps it gives an outline of how to install Guix on Silverblue for a hacker who'd like to try it :)

These projects use Caddy as my local development server, Dart Sass for converting my Sass files to CSS, elm, elm-format, elm-optimize-level-2, elm-review, elm-test (only in Calculator), ShellCheck to find bugs in my shell scripts, and Terser to mangle and compress JavaScript code.

ShellCheck: https://github.com/koalaman/shellcheck

If I want to write better shell scripts I usually run shellcheck and adjust accordingly or if I need facilities not provided by the shell i switch to a full fledged programming language. Ans oh yes, `sh` is present almost on every BSD and Linux box for free so I consider it an important thing to at least be comfortable with.

shellcheck: https://www.shellcheck.net/

When I run nix-shell at the root of the project it puts me in a Nix shell that contains, among other programs, caddy and shellcheck. Notice that in the shellHook I add the project's shell scripts to the PATH. So once I'm in the Nix shell I can, among other things:

I have also seen some projects on github like ShellCheck which first make a library, expose all the modules and then simple add that do build-depends of the final executable. Is this the recommended approach than having just one executable and adding all the modules to other-modules:?

The error checks can be pretty arcane:

Similar to for instance shellcheck to check the syntax of shell scripts, is there an equivalent for the set of roff commands typically used in a (Linux) man page? I'm aware that e.g. pandoc permits the conversion of an other format (e.g., org) to both roff man and roff ms.
