Any way to use custom tags with the new LIQUID sigil?

Description

I am attempting to add liquid support via solid to my static site generator (tableau) and the new LIQUID sigil looks awesome. I used to have an implementation of my own L sigil, before I moved my personal blog to a different template syntax.

I'm trying to create a tag that basically renders a HEEx component, but I don't think its currently possible to globally set custom tags in a way that the sigil can see them.

Do you think this is possible?

Hi @mhanberg ! First thanks for tableau (I'm using it for my blog!) and for the work on elixir-tools!

Oh yeah that's a great question. I think we should be able to do this with use something like:

  @tags Solid.Tag.default_tags()
        |> Map.put("current_line", CustomTags.CurrentLine)

  use Solid.Sigil, tags: @tags
  
  template = ~LIQUID"Hello, {{ name }}!{% current_line %}"

It would define the sigil macro passing the __using__ opts to Solid.parse!.

WDYT?

Wow, I'm honored! 💜

I think that approach sounds good. I think potentially you could make the sigil look for a @liquid_tags attribute at compile time, and not need the using macro.

import Solid.Sigil

@liquid_tags Solid.Tag.default_tags() |> Map.put("current_line", CustomTags.CurrentLine)
~LIQUID"Hello, {{ name }}!{% current_line %}"

Tangentially related to this, I wonder what you think about adding an API around the adding/removing tags. The current API implies and couples the structure to a map with string keys.

Something like this would hide that structure as well as add an implied route for doing this (search docs/autocomplete, see function)

Solid.Tag.default_tags()
|> Solid.Tag.add(:current_line, CustomTags.CurrentLine)
|> Solid.Tag.remove(:comment)

Love the ideas! Thanks!

Yeah the tags option can definitely benefit from a nicer API 👌
