[PD-dev] "modular" compositions of object classes

[mescalinum at gmail.com]

hi all,

is it possible -in the context of writing a pd external class- to
invisibly patch some other object and attach to it/bind it?

I'll try to explain better with an example:
if I were writing an external that is somewhat an interface to arrays
(read/write), I have some design choices:

1) copy/paste the code of array (g_array.c) (or eventually only copy
[tabread]/[tabwrite])
    pros: resulting external is tight & tidy
    cons: code duplication, possible breakage in future releases

2) provide appropriate inlets and outlets, and require the user to patch
the external among [tabread]/[tabwrite] objects
    pros: modular. is independent from the array implementation.
    cons: tricky to use, the user can patch it incorrectly and won't work.

3) is possible to patch the required objects without phisically put them
in the canvas [?]
    pros: all pros mentioned in 1) and 2)
    cons: [?]

obviously, 1) and 2) are ugly under some point of view; what I am
interested in is 3), hence asking here if possible, and directions on
how to proceed.

thanks
