This article will introduce you to Alejandra formatter, as well as teach how to leverage the Nix build system to easily patch any source code. This is the continuation of my previous article exploring nix formatters ecosystem.

Thanks! I have been waiting for this post as I am also uncompromising :).
One issue that remained is that multi line strings still get 2 space indented. I fixed this by adding another substitution to the postPatch:

substituteInPlace src/alejandra/src/rules/string.rs \
--replace 'format!("  {}", line)' 'format!("    {}", line)'

The multi-line string indentation has it's own specific rule and is hard coded.

I hope this helps someone!
