Hi all,
I have a need to merge a list of maps of lists:
heat_template_version: 2016-10-14
outputs:
debug:
value:
yaql:
# dict(vms=>dict($.vms.select([$.name, $])))
expression: dict($.data.l.select([$.keys().toList()[0],
$.values().toList()[0]]))
data:
l:
- a: [123]
- b: [123]
- a: [456]
I want to end up with debug as:
a: [123, 456]
b: [123]
Perhaps we need a map_deep_merge function, but can this be done with yaql?
I suspect it can, but can't currently figure out how the assignment to the
intermediate "a" value is supposed to work, any ideas on the cleanest
approach appreciated!
Thanks,
Steve
