[bug] Nested interpolations don't work #212

Closed

Nested interpolations only resolve inner level interpolations.

a = OmegaConf.create({"a": "${hello:${default_hello:}}"})
OmegaConf.register_resolver("hello", lambda x: x)
OmegaConf.register_resolver("default_hello", lambda: 1)
print(a.a) # prints ${hello:1}

Expected: 1

The major issue this causes is when I want to register a resolver for an environmental variable's default value.

Workaround:
Register an overall resolver and resolve environment value yourself in it.
