Prettier QML Plugin

WORK IN PROGRESS

Please note that this plugin is currently in alpha stage and still under active development. We encourage everyone to try it and give feedback, but we don't recommend it for production use yet.

Intro

Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.

This plugin adds support for the QML language to Prettier.

Install

yarn:

yarn add --dev prettier prettie-plugin-qml
# or globally
yarn global add prettier prettie-plugin-qml

npm:

npm install --save-dev prettier prettie-plugin-qml
# or globally
npm install --global prettier prettie-plugin-qml

Use

If you installed prettier as a local dependency, you can add prettier as a script in your package.json,

"scripts": {
  "prettier": "prettier"
}

and then run it via

yarn run prettier path/to/file.qml --write
# or
npm run prettier -- path/to/file.qml --write

If you installed globally, run

prettier path/to/file.qml --write

Editor integration

Atom

The official prettier plugin for atom supports plugins.

VScode

Regarding plugin support in the official plugin prettier-vscode see this issue.

Alternatively, install Run on Save and add the following section to your settings:

"emeraldwalk.runonsave": {
  "commands": [
    {
      "match": "\\.qml$",
        "cmd": "prettier ${file} --write"
    }
  ]
}

Vim

Regarding plugin support in the official plugin vim-prettier see this issue.

ALE

The linting plugin ALE has built-in support for prettier and its plugins. Just add prettier to your list of fixers. For example:

let g:ale_fixers={
  \'javascript': ['prettier'],
  \'json': ['prettier'],
  \'qml': ['prettier'],
\}

Custom

Alternatively, adding the following to .vimrc will define a custom command :PrettierQml that runs the plugin while preserving the cursor position and run it on save.

" Prettier for QML
function PrettierQmlCursor()
  let save_pos = getpos(".")
  %! prettier --stdin --parser=qml
  call setpos('.', save_pos)
endfunction
" define custom command
command PrettierQml call PrettierQmlCursor()
" format on save
autocmd BufwritePre *.qml PrettierQml
