First send text from snippet editor to ride below, using the span of whichever subject I've explicitly defined. How do I go about defining the subject which snippets are run against? Call ride, with span as *, which will produce Nock. Then take the Nock and run it with .*.

 ++  ride                                                ::  end-to-end compiler
   |=  {typ/span txt/@}
   ^-  (pair span nock)
   (~(mint ut typ) %noun (ream txt))
::

Pretty printer: text calls deal:us that takes a span and a noun and prints the noun according to the rules of span. It prints that to the printable format tank. deal:us is vase -> tank, as is cell. re core takes tank and produces a tape. ram:re and deal:us are combined in text.

Experiment with building custom subjects instead of the one that apps get by default. Maybe mimic the ones that generators get.

=rid (ride p:!>(.) '42')
(text p.rid .*(. q.rid))
