export default defineConfigWithVueTs(

What did you do?

<script lang="gleam">
import gleam/io

pub fn hello () {
 io.debug("hello")
}
</script>

<template>
  <main>
    <TheWelcome />
  </main>
</template>

What did you expect to happen?

Script block with lang="gleam" should have been skipped

What actually happened?

Block was not skipped, and eslint ran into a parsing error

Repository to reproduce this issue
You can paste the code above into any pnpm create vue app. Let me know if you need a repo

I don't use gleam and you don't provide a reproducible repo so I can't try it, but I think you can change the parser configuration.
See the documentation:
