Allow to ignore based on languages

Environments:

• Prettier Version: 1.15.1

Steps to reproduce:

As a user I want to ignore certain languages that are part of a larger file that I do want to format.

• App.vue

<template>
  <div id="app">
    <img src="./assets/logo.png">
    <HelloWorld/>
  </div>
</template>

<script>
import HelloWorld from './components/HelloWorld'
export default {
  name: 'App',
  components: {
    HelloWorld
  }
}
</script>

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

I don’t want to format the HTML template

• .prettierignore

{
  "languages": ["html"]
}

Expected behavior:

Prettier format the file, but the HTML template.

<template>
  <div id="app">
    <img src="./assets/logo.png">
    <HelloWorld/>
  </div>
</template>

<script>
import HelloWorld from "./components/HelloWorld";
export default {
  name: "App",
  components: {
    HelloWorld
  }
};
</script>

<style>
#app {
  font-family: "Avenir", Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

Actual behavior:

There is no way to ignore a part of a file based on the language.

Why isn’t option 1 (use eslint-config-prettier) a good choice for you?

Because using this means no longer following the style guide.

Because if I’m not following a predefined style guide, I would have to manage / define my own for other team members to use.

Best practice would be to use the standards defined by the framework.
