--list-different does not work when use --write, using prettier+prettier-eslint+prettier-eslint-cli

[dzhytomyrsky]

I wrote such npm script in my package.json:

"format-js": "prettier-eslint --print-width 100 --list-different --write 'webpack/**/*.js' 'development/**/*.js'"

it formats my js, but does not print prettified files. Is it possible to use --list-different with --write?

If not, it would be great to))

I'm not sure whether it's possible. I don't use that feature. Could you describe your use case?

Hey, @kentcdodds,
When running prettier --list-different --write it formats all files and prints all paths of prettified files.

Unfortunately prettier-eslint behaves differently.

> prettier-eslint --list-different --write "./src/**/*.js"
success formatting 28 files with prettier-eslint
14 files were unchanged

A use case would be integrating the formatting to lintstaged.
E.g.:

"lint-staged": {
    "*.{js}": ["prettier-eslint --list-different --write \"./src/**/*.js\"", "git add"]
}

Here lintstaged is expecting a list of pathnames to pass it along to git add after formatting.

Well, I'm aware that this is not a very common use case because modifying files on precommit hook could be a dangerous thing.
But anyways, I thought that prettier-eslint tries to provide a similar API compared to prettier. Or am I wrong? :)

I believe there are at least two options:
a) printing pathnames like I mentioned above
b) telling the user that combining --list-different & --write is not supported (yet).

What do you think?
