vue-cherry-compiler-patch v1.0.3

vue-compiler-sfc-cherry-cljs

Currently Vue seems to break when you use <script lang="cljs"> due to a bug (see vuejs/core #8368 and vitejs/vite-plugin-vite #178). This is just a drop-in replacement for the compiler.parse function used in @vitejs/plugin-vue.

It could be tweaked to use Squint or probably any other language (like CoffeeScript) which is hitting this issue.

What it does

It's hacky and I just threw it together, but it works. It:

• Intercepts Vue SFC files which contain <script lang="cljs">
• Strips the script block into three parts:
  • Opening tag
  • Content
  • Closing tag
• Passes the content into cherry-cljs.compileString() to compile it to JSX
• Changes the opening tag from <script lang="cljs"> to <script lang="jsx">
• Constructs a new script block using the modified parts
• Replaces the old script block in input with the new
• Passes the new input into vue/compiler-sfc.parse() and returns

It's hacky, but it works. Hopefully, the bug will be addressed by someone more capable than myself and I can go back to using a Vite plugin to do this.

Usage

imoprt vue from '@vitejs/plugin-vue'
import { cherry-parse } from 'vue-cherry-compiler-patch'
import * as compilerSFC from 'vue/compiler-sfc'

export default defineConfig({
  plugins: [
    vue({
      compiler: {
        ...compilerSFC,
        parse: cherry-parse,
      }
    })
  ]
})
