Possibility to transfer it nicely when using tailwindcss

[vcharov]

Request / Idea

It would be nice to be able to transfer it nicely when using tailwindcss. This would make the code much more readable

Input

MenuButton(
  class=["relative z-10 flex items-center w-11 gap-2 whitespace-nowrap text-ellipsis overflow-hidden text-xs", "lg:gap-6"]
)

Expected Output

MenuButton(
  class=[
    "relative z-10 flex items-center w-11 gap-2 whitespace-nowrap text-ellipsis overflow-hidden text-xs",
    "lg:gap-6"
  ]
)

Is it expected / correct that you didn't use quotes but class=[ ... (instead of class="[ ...)
If yes I'm afraid you are running into the same problem as many other users did before you => #66

This is a limitation of pug itself and is currently not really handleable 😔

[vcharov]

you can write it that way, but it looks strange

MenuButton(
  class={
    "relative z-10 flex items-center w-11 gap-2 whitespace-nowrap text-ellipsis overflow-hidden text-xs": true,
    "lg:gap-6": true
  }
)

class={ results in the same issue
It's the parser that has the problem, not the formatter

[vcharov]

Maybe there is a way not to make a fix for these cases?

header.header-module(
  class=[
    "bg-off-white shadow-main-header flex items-center gap-x-2 py-2 px-4",
    "lg:px-8"
  ]
)

I'm open to PRs
Please open a PR and add a test, you can orientate yourself on any test inside https://github.com/prettier/plugin-pug/tree/main/tests/issues
Happy to review your solution

Did I understand you correctly, there is no such rule at the moment?

Did I understand you correctly, there is no such rule at the moment?

You are in the repo for the pug formatter
A formatter doesn't have rules, but options
The rule that got triggered in your screenshot is coming from https://www.npmjs.com/package/eslint-plugin-prettier-vue

thanks for the help

[vcharov]

Please advise where is the parsing code

[Shinigami92]

Please have a look into this: pugjs/pug#3214

[vcharov]

The point is that the parser works correctly, the expected code is valid and works correctly. But plugin:prettier-vue/recommended prohibits such hyphenation
