• Driving OR iterated

• Runner? Executor?

  • hooks up source to flow,
  • if iterated source, drives it, otherwise sits in the flow

• these set the contract for the inbound products

slots

Typical case: one input, :input, one output :output

• there are as many products as
  • the total number of action stage outputs
  • the concrete input products
• The number of rsrc->action edges is at most the total number of input slots
  • (you cannot wire multiple products to the same input slot)

1. action stage B wires up to an action stage A (which really means "the full set of A's outputs")

2. I wire action A's output as production product X

4. How do I address other stages?

   • mapper.cat a great name for action stage cat inside chain mapper
   • mapper.cat:output? mapper.cat_output?

Subgraphs own their contents

Configuration

• options on processor become options on flow -- so, in the telegram example, :break_length becomes configurable (somehow)

Tests

• add an examples helper -- runs script on file from data dir, diffs the output.

---

• Ruby-Graphviz Ruby interface to the GraphViz graphing tool

• Ruby GraphML Parser

• everything accessible from clean (non-magical) methods.

• inputs and outputs:

  • inputs and outputs become an array of symbols

• You can only have as many macro edges as inputs

• action stage 'ports'

  • a list of names for them

  • can also have an edge going to a

create a product with no action? action with anonymous product, wired up later?

• connections:

  • action -> action:

    act_a -> actb
    

    act_a :o1 -> rsrc_x act_a :o2 -> rsrc_y

    act_b :i <- act_a
