(execute config steps ctx on-success on-anomaly on-exception)

Sequentially executes the series of given steps.

Each step function - tap or processor - can be synchronous or asynchronous.

• config: A map with:

  • [opt] anomaly? A function that gets a map and determines if it is an anomaly.
  • [opt] log-exception A function gets called with the FondaContext record when there is an exception.
  • [opt] log-anomaly A function that gets called with the FondaContext record when a step returns an anomaly.
  • [opt] log-success A function that gets called with the FondaContext record after all steps succeeded.
  • [opt] initial-ctx The context data initializes the context. Must be a map.

• steps: Each item on the steps collection must be either a Tap, or a Processor.

  Tap:

  • tap: A function that gets the context but doesn't augment it.
  • name: The name of the step

  Processor:

  • processor: A function that gets the context and assocs the result into it on the given path
  • path: Path where to assoc the result of the processor
  • name: The name of the step

• ctx The runtime context, merged to the initial context. Must be a map.

• on-success Callback that gets called with the context if all the steps succeeded.

• on-anomaly Callback that gets called with an anomaly when any step returns one.

• on-exception Callback that gets called with an exception when any step triggers one.
