How do I format zsh code (something like prettier / shfmt)?

Question

For bash and sh, there is shfmt.

How do I format zsh code?

I'd like to be able to set some options like in shfmt, ie:

  -i uint   indent: 0 for tabs (default), >0 for number of spaces
  -bn       binary ops like && and | may start a line
  -ci       switch cases will be indented
  -sr       redirect operators will be followed by a space
  -kp       keep column alignment paddings
  -fn       function opening braces are placed on a separate line

zsh-hist says it supports "uniform code formatting", but I can't work out how to run it from the command line and it's main purpose is history manipulation.

How do I format zsh code either in the shell or via something like VSCode prettier?

Are you searching for a pretty-printer for zsh, similar to shfmt for bash, or are you going to write your own pretty-printer? – Blotto

I'm looking for a method to format zsh code without writing a tool from scratch. – Goggle

Perhaps you could start by taking shfmt as a base, and create from this your own formatter? Since zsh and bash are syntactically quite similar in spirit, this should be much less work than starting from scratch. – Blotto

Could you share an example fie you're trying to format? – Kurtzig

While it's still not implemented (as of Jan 2023), this issue on shfmt by the author from 2021 sounds like there is interest in implementing support for it: github.com/mvdan/sh/issues/120#issuecomment-903077180 – Rodin
