Custom tags are handled in block-formatting context

[jongio]

🐛 Bug Report

Whitespace in innerHTML is not preserved.

To Reproduce

When you format this:

<template>
 <div id="app">
  <div id="nav">
   <router-link to="/">Home</router-link> |
   <router-link to="/about">About</router-link>
  </div>
  <router-view />
 </div>
</template>

Expected behavior

The space after Home</router-link> should be preserved.

<template>
 <div id="app">
  <div id="nav">
   <router-link to="/">Home</router-link>|
   <router-link to="/about">About</router-link>
  </div>
  <router-view/>
 </div>
</template>

Hi @jongio the reason is that we handle custom-tags in case-insensitive context. I would accept a PR to handle all custom tags as case-sensitive. As a workaround you could do:

<template>
 <div id="app">
  <!--prettyhtml-preserve-whitespace-->
  <div id="nav">
   <router-link to="/">Home</router-link> |
   <router-link to="/about">About</router-link>
  </div>
  <router-view/>
 </div>
</template>

@StarpTech - Are you saying that the space is removed due to case sensitivity? I'm not following that, but I also don't know the code. To me, not sure that new title describes the issue.

Hi @jongio you're right the title wasn't accurate. For more informations see https://medium.com/@patrickbrosset/when-does-white-space-matter-in-html-b90e8a7cdd33

Hello, I don't know why this library is introduced into the Vue project. With this API, the project will not run. They say we can't find the third party. Can you help me? Thank you very much.
