add support for custom language mapping to hard-coded string extraction

[alexanderniebuhr]

Describe the solution you'd like:
Would like to have an config option to map .svelte files to the html parser of hard-coded string extraction, it should work with no issue since they are just html files with <script> & <style> tags, which can be excluded already

[terales]

Here is an example of the generic Svelte file:
https://github.com/sveltejs/template/blob/master/src/App.svelte

@alexanderniebuhr can you share a link to an internationalized Svelte project, please?

[alexanderniebuhr]

Not having a public one for now (working on one in private repo), can attach it later this week, since it is going public by then. However, a Svelte file with internationalization would look similar like

<script>
  import { _ as t } from 'svelte-i18n'
</script>

<div>
  <f-button class="bg-light-300" on:click={(e) => handle365Login(e)}>
    {$t('page.login.ms365')}
  </f-button>
  <f-button class="bg-light-300" on:click={(e) => handle365Logout(e)}>
    {$t('page.logout.ms365')}
  </f-button>
  <f-button class="bg-light-300" on:click={(e) => handle365Logout(e)}>
    Text to extract
  </f-button>
</div>

<style>

</style>

this is an example by svelte-i18n

<script>
  import { _ } from 'svelte-i18n'
</script>

<h1>{$_('page.home.title')}</h1>

<nav>
  <a>{$_('page.home.nav', { default: 'Home' })}</a>
  <a>{$_('page.about.nav', { default: 'About' })}</a>
  <a>{$_('page.contact.nav', { default: 'Contact' })}</a>
</nav>

@antfu works not for some edge cases. This file breaks with Unexpected token (1:3)

Extracted into a separate issue: #623
This particular exception is trickier than the initial request.

Does everything work well with the removed commented script tag?

[alexanderniebuhr]

Yes, it does work well,
expect that already extracted keys are matched as hard-coded Strings.

But minor stuff, which is expected, since it is an experimental feature ;)

[terales]

@alexanderniebuhr Matching already extracted strings is somewhat unexpected 😞

Can you share a few examples in a separate issue, please?

[alexanderniebuhr]

I will open any findings in a new issue. Nevermind about the extracted strings, can't reproduce it anymore.
