Thanks Aaron. Seems you've had some experience with this, so..
I'm a little confused about how it loads complex data. With a very simple
YAML file like this:
---
testkey:
- Doug
- Bob
- Bill
calling $test_var = extlookup('testkey', '---', 'settings') gives me a
string 'DougBobBill', which isn't what I expected to see. Actually, now that
I think about it, I'm not sure what I'm supposed to see.
Also, if I had this:
---
testkey1:
testkey2:
- Doug
how do I access the key testkey2?
Doug.
