[PD] rabin~ tricks

[Krzysztof Czaja]

hi,

this is about my (yet another) attempt to design a multi-abstraction
embedder.  The goal is to be able to use just ordinary abstractions,
with inlets and outlets, instead of poly~ way of using specialized
patches with [in]s and [out]s.

Of all the ways to cheat, I have chosen what seemed the safest one.
It may look naive, but you be the judge:

After loading an abstraction, but before creating objects in it,
I rename all [inlet]s to [in]s, all [inlet~]s to [in~]s, etc.
Then, after creating them as instances of my replacement classes,
but before showing them (or saving), I rename them back to
[inlet]s, etc.  So when user happens to click on a [rabin~] box,
a subwindow actually contains [in], but with "inlet" text in the
box (and is saved as an inlet).

The release at suita.chopin.edu.pl/~czaja/miXed/externs/rabin.html
is only a proof of concept.  Most of the needed features are
missing, like:  multiple inlets and outlets, after-noteoff control
(thispoly~?), nested abstractions, automatic [switch~]ing, and many
many more.  It does not work with older versions of Pd (and never
will).
