pedantix

pedantix is the pedantic Nix formatter.

It runs your base formatter of choice (nixfmt(-rs), alejandra, nixpkgs-fmt, or an arbitrary command of your choosing) and then applies reordering on top. Every feature is optional.

On by default:

• ordering of function arguments
• ordering of attributes

Off by default:

• ordering of inherits (a case could be made that this should be on by default)
• ordering of let bindings
• ordering of lists
• merging of repeated keys (this does not fix broken evaluations)
• flattening of attribute sets with a single entry
• (un-)quoting of attribute names
• enforcing of blank lines in between attribute sets
• overrides for arbitrary attribute paths

Comment blocks stay attached to their belonging configuration (mostly! - see How it Works).
