How to access `site.data[“foo.bar.baz”]` if `foo.bar.baz` is a FrontMatter variable

I want something like:

---
my_var: "foo.bar.baz"
---

{{- site.data[page.my_var] -}}

Unfortunately, it doesn’t work…

I know that I can use site.data.foo.bar.bazor site.data["foo"]["bar"]["baz"], but it’s not that.

Also I know that I can split page.my_var to substrings and use them then as site.data["foo"]["bar"]["baz"]. But this increases Jekyll build time.

I guess I need some Ruby plugin, but don’t know one and I don’t know Ruby to write one.

If you know such plugin or can help me write one or know some native workaround, this would be sooo great!

Help :slight_smile:
