Array to Map

Use this operator to convert an array to..a map. Skips over null values.

Behind the scenes, this is implemented using reduce:

(.[] | select(. != null) ) as $i ireduce({}; .[$i | key] = $i)

Simple example

Given a sample.yml file of:

cool:
  - null
  - null
  - hello

then

yq '.cool |= array_to_map' sample.yml

will output

cool:
  2: hello
