What did you do? Please include the actual source code causing the issue.

<template lang="pug">
  #app
    img(alt='Vue logo', src='./assets/logo.png')
    hello-world(msg='Welcome to Your Vue.js App')
</template>

<script>
import HelloWorld from './components/HelloWorld.vue'

export default {
  name: 'app',
  components: {
    HelloWorld
  }
}
</script>

What did you expect to happen?

• Create vue app by vue-cli3 with lint ( eslint & prettier )
• Add pug support, yarn add pug pug-plain-loader -D
• Edit the template of App.vue use pug, got incorrect lint.

What actually happened? Please include the actual, raw output from ESLint.

yarn lint --fix then

<template lang="pug">
  #app img(alt='Vue logo', src='./assets/logo.png') hello-world(msg='Welcome to
  Your Vue.js App')
</template>

<script>
import HelloWorld from './components/HelloWorld.vue'

export default {
  name: 'app',
  components: {
    HelloWorld
  }
}
</script>

work around

<!-- prettier-ignore -->
<template lang="pug">
  #app
    img(alt='Vue logo', src='./assets/logo.png')
    hello-world(msg='Welcome to Your Vue.js App')
</template>

<script>
import HelloWorld from './components/HelloWorld.vue'

export default {

Please watch/star https://github.com/Shinigami92/eslint-plugin-vue-pug-sfc I will try to tackle eslint vue pug support in next time

[Shinigami92]

https://www.npmjs.com/package/eslint-plugin-vue-pug-sfc/v/1.0.0-alpha.2 👀

This is a first alpha and “supports” vue-pug-sfc/this-in-template for the never option. always is currently NOT supported due to it is much harder to implement.

Please give it a try and please also start to create issues in the repo for every rule you want to get support for! Please do NOT use the --fix option right know (or at least with a backup), cause it can damage your code! The ranges are not accurate yet so the ~~~~ lines are positioned to broad right now.

Please also feel free to jump into the code and help me 😃 If you use VSCode jump into the Debug Launcher and run the tests with debug-breakpoints.

Please note, if you consider this plugin as helpful, that I’m open to receive money via GitHub sponsoring. I would really appreciate it.

I will not spam here anymore, so please lets move all discussions to the project’s repo.
