How do I pass CLI or API options to prettier when running ALEFix?

[TheButterflyMon]

I have set up Prettier as the ALE fixer for HTML files as follows:

  let g:ale_fixers = {
        \ 'html': ['prettier'],
        \ }

In Prettier, I would like to set the "Bracket Line" option as true so that Prettier puts the > of a multi-line HTML element at the end of the last line, instead of being alone on the next line. First, I first tried using configuration files as suggested on the Prettier site. I added the following option to my .prettierrc file:

  "prettier": {
    "bracketSameLine": true
  }

This did not work, so I followed the second advice on https://prettier.io/docs/en/vim.html and added the option to my .vimrc:

let g:ale_html_prettier_options = '--bracket-same-line'

This failed, too. How can I provide options to the Prettier fixer so that it works with ALEFix?

The prettier fixer uses this configuration g:ale_javascript_prettier_options. This is used by the fixer for all languages it supports (e.g. javascript, html, etc.)

Thank you for the answer. It works for all options, except -bracket-same-line. For example, let g:ale_javascript_prettier_options = '--print-width 120' sets the line length to 120. I suspect that there is a bug somewhere with the -bracket-same-line option.
