This leads to the question: should tooltip messages be
per-instance or per-class? It could easily just be a
field with a standard name in each object's struct, then it
would be a simple per-class implementation. Having an
'assist' method means that the external writer can decide
whether the string is per-class or per-instance.
Yes... whichever is appropriate. But the default
assist-method should be designed so that in most cases,
externals don't need to have a custom assist-method.
I don't see a need to extend any structs, Pd just
needs to call an object's assist method whenever the mouse
is hovering over one of its inlet/outlets,
A default assist-method needs to be storing data somewhere,
and it cannot automatically pickup inlet names from anywhere
in an external's source code. It has to be stored in some
data-structures... For example, in both t_class and t_inlet
(for nonproxy inlets).
Is it possible in c to parse a help file for "OUTLET_0 float
symbol"? That's what I'm currently doing (which is trivial on the
tcl side).
Actually the way I do it, you parse on the fly only when the mouse
hovers over the xlet (which you could toggle with a menu button).
Parsing text in C is definitely possible, just not fun. Its much
easier in Tcl.
This is an important point that Jonathan brings up: if
we add an 'assist' method, that could mess up anything that
ever sent a message that started with 'assist'.
Then just do it like it is for savefn and propertiesfn. You
see, it doesn't have to be something that goes through
class_addmethod. The 'assist' symbol issue is not an
argument against defining an assist-method because it could
be a field named assistfn directly in t_class.
What do I have to do to register a new "assistfn"? I don't really
understand that part of the source code.
That would require adding the assistfn to the t_class structure.
