Hah, yeah that's a great idea, although you might not want to look at the C source ;)

But there are some subtle dangers to openness.
Given the very small size of Pd patch code in relation to even the simplest compiled external we might agree a principle, a standard, an unwritten law if you like....
that any pd abstraction converted by a [gen~] like mechanism into a compiled external, carries with it the dataflow source as a data chunk. That means the dataflow source is always distributed with it. Further the whole process is reversible with a "convert-external-to-abstraction" process.
What we would have then is a kind of great "folding editor/compiler" for DSP development where two views of code are possible. This would be powerful in teaching C as well as data-flow with the same tool.

Exactly ;)
And again, let me add, there are things like the heavy compiler, https://enzienaudio.com where you can compile pd patches into optimized
code
how does that work? Wouldn't that be something like the "gen~" idea I brought up? How hard would it be to have a compiler for a patch to be turned into a coded object?
if abstractions could do anything a compiled object could do including being optimized and efficient, that would be amazing...

Miller did seem open to a control outlet on the inlet~ object. This was when we were discussing the clone object and how you have to pass
messages
to the first control inlet, if you have one, instead of just the first inlet always, to control the cloning operations. More generally, it
would
be great if abstractions could do anything a compiled object could do. Alex

Hi Alexandre,
I wonder if a thing like libpd could work as turning a vanilla
patch
into a
compiled object to be used inside pd... that'd be something like
gen~
in
max/msp.
Can you be more specific ? For the moment, I think it would be equivalent to use an abstraction or the object [pd~] (libpd loads dynamically a patch so I guess that the execution of the patch
cannot be
optimized and except if the patch has been be somehow included
inside the
binary, you'll have to share the patch with the object). For me, the
main
advantage of gen~ is that it generates code that can be used inside
an
application but libpd already offers this feature. So what would be
the
advantage?
Well, I thought the code could be optimized somehow, which I believe
is
something gen~ does, and that could be an advantage... but I really
know
nothing and now it seems that is not possible.
A - being able to retrieve control data from [inlet~]
I did it in the Cicm Wrapper but it was pretty tricky. If you use the object [hoa.process~], you can send messages via a signal inlet for example. I'm not very proud of this because I had to hack a bit the
inlet
class. Now, I don't know if I must remove this feature or keep it... Perhaps somebody could tell/remind us if there is a reason why signal inlets can't receive messages.
cool, there's also a [route~] object from zexy which could be
embedded in
inlet~
B - being able to know if a signal is connected to [inlet~]
I also did it in the Cicm Wrapper, perhaps this feature could be included in the "m_pd.h" interface because for the moment you need to include "g_canvas.h" and "m_imp.h". Anyway, if you want a simple
code that
shows how to do it, I have an example <https://github.com/pierreguillot/pd-dummy/blob/
master/src/connected_tilde.c>
in my dummy library.
awesome, it's be great to have something like this in vanilla in
order to
improve the design of abstractions ;)
cheers
