Svelte Slider snippet with arguments

[endigo9740]

Discussed in #3201

^{Originally posted by Akkretion February 9, 2025}
Hey guys, it seems to me that in the Svelte Slider implementation the Slider always goes from 0 to 100. I can specify markers (from 0 to 100) which appear as numbers at their respective positions. I can also pass a snippet that is rendered at these positions instead, but it is constant.
I would like to pass a snippet which takes an argument (i.e. the marker value) so I can render different Icons or numbers in case I want the slider to represent something else than the numbers 0 to 100.
Currently there is no way to do that, right?
But the change in the implementation of the component would literally just be changing

...
{#each markers as value}
<!-- Mark -->
<span {...api.getMarkerProps({ value })} class="{markBase} {markText} {markOpacity} {markClasses}" data-testid="slider-mark">
	{#if mark}
		{@render mark()}
	{:else}
		{value}
	{/if}
</span>
{/each}
...

to

...
{#each markers as value}
<!-- Mark -->
<span {...api.getMarkerProps({ value })} class="{markBase} {markText} {markOpacity} {markClasses}" data-testid="slider-mark">
	{#if mark}
		{@render mark(value)}
	{:else}
		{value}
	{/if}
</span>
{/each}
...

Should I open a Pull request?

As I said there:
Not sure if there is anything else that I should do in order for this to be mergeable.
Pipelines are red. Also, I am not sure if there are any relevant docs I should update.
Sorry, this is my first time "contributing" to this project.
Let me know!
