for_each>: Repeat tasks for values¶

for_each> operator runs subtasks multiple times using sets of variables.

+repeat:
  for_each>:
    fruit: [apple, orange]
    verb: [eat, throw]
  _do:
    echo>: ${verb} ${fruit}
    # this will generate 4 tasks:
    #  +for-fruit=apple&verb=eat:
    #    echo>: eat apple
    #  +for-fruit=apple&verb=throw:
    #    echo>: throw apple
    #  +for-fruit=orange&verb=eat:
    #    echo>: eat orange
    #  +for-fruit=orange&verb=throw:
