Convenient way to disable per file

[steinarb]

There are some files I would like to exclude from prettier formatting, because they are more readable if I can have one line per declaration:

1. The redux actions definitions files (e.g. like this one)
2. The reduxjs toolkit reducers (e.g. like this one)

Currently I solve this by switching to fundamental-mode before saving.

But this is a nuisance, and especially when I forget to switch mode before saving, and don't see it until the change has been committed and pushed (like what happened today).

So it would be nice to have the exclusion automated.

I always mark the files that should be left alone with this (so eslint won't fail the build):

/* eslint-disable prettier/prettier */

Hi, sorry no one was able to get back to you in the long time since you asked for help here.

Ultimately, I think the best way for you to handle this will be to use .prettierignore (once it's fixed; see: #62), or to switch to using the ignores Prettier config option to specify the files to ignore (once that feature is merged into Prettier: prettier/prettier#16286). Those solutions will be easy for you to configure, and they will be standardized so they work for your whole team, regardless if the people on your team use Emacs.
