Link to the dictionary of Siberian barley

Question

I am trying to organize variable definitions for downloadable books.

Example:

a_b: "a b"
a_c: "{{a_b}} c"

It works great.

Trying to turn this into a dict:

a:
  b: "a b"
  c: "{{a.b}} c"

Unfortunately, this leads to an error that a.bis undefined.

Is it technically possible to refer to kinship elements in a dict?

Answer 1

You cannot reference variables during the variable phase "init". You can use set_factfor reference {{ a.b }}.
