Qig

qig is dig extended with jq's "value iterator" [] operator and some other goodies.

Qig.qig(subject, *path) # => contents of subject at path

examples:

# dig-like usage
Qig.qig({ a: { b: { c: 1 } } }, :a, :b, :c) # => 1

# dig-like usage augmented with jq's [] operator
Qig.qig({ a: { b: [{ c: 1 }, { c: 2 }] } }, :a, :b, [], :c) # => [1, 2]

# after expanding values, collect them back into an array for indexing into with `[[]]`
Qig.qig({ a: { b: [{ c: 1 }, { c: 2 }] } }, :a, :b, [], :c, [[]], 1) # => 2
