base_output: useless with array results

[loopfz]

• I'm submitting a ...

  • [ ] bug report
  • [x] feature request

• What is the current behavior? if I configure

base_output:
    foo: bar

for a step that returns an array, my base output is ignored.

• What is the expected behavior? I'd like to be able to access my base output (important to keep local context in foreach step chains). This could mean that the base_output should be injected in each item of the result array? Then how does this work if the result array is a list of scalars (ie, list of IDs) ?

Hi, we inject the iterator object in the children metadata (see #414). This could be enough for you?

As we discussed, it could be a good idea to add the 'base_output' content to each item in a slice.
