Passing strings to function calls

[brandonpittman]

Am I correct in thinking that:

<script lang="ts">
  set_some_context({title: "Something"})
</script>

…would not extract the "Something"?

Doing the above doesn't appear to get extracted and if I set it in a variable and pass it to the function results in Svelte warning me about only the initial state of the generated $derived() being captured.

I can do this:

<script lang="ts">
  set_some_context({title: /* wc-include */"Something"})
</script>

…but that feels like introducing tool-specific hacks for no good reason. What's the best way to handle passing text to function calls (like context setters).

Hi @brandonpittman, sorry for the delay. The default heuristic is that expressions (values not assigned to a variable) in the script block are not extracted. Since this seems to be a one-off situation, the cleaner way seems to be the include comment. When you extract it to a variable, it is auto wrapped inside $derived because it either has to be a function call or a derived value to be updated later if the locale changes.
