Hey all, So for the Pd-0.40.3-extended release, I am planning on trying to make the internals available as a library like any other. I'd like this work to be applicable to pd-vanilla, so I'd like to discuss how to make it happen.
cyclone does something like this (it overrides already registered externals, which - at this point - are not different from internals)
it is basically looking whether the class-name is already registered, and if so, overwrites the class-pointers.
however, for this to work, you need first need to call a function in your overriding new library. therefore you will probably need something like a "library" (instead of single, same-named externals)
I'd rather not use a special mechanism, especially if it is not already widely used.
I was thinking of just breaking out the classes into their own files, then compiling things as a libdir. This is pretty easy for most of the objects, but I haven't gotten into the DSP classes yet, and I expect things will be more complicated there. And [list] too.
funnily enough i have always been opposed when requesting that the [list] objects get _proper_ names.
Why? For example, [list append] will happily append a symbol to a float, so the "list" part doesn't seem so accurate. Why not just [append]?
One of the things I am planning on doing for the tkwidget library is making it have a shared libtkwidget.so which each of the object classes uses. Then each objectclass will have its own file, but they still will have shared code. If this works out well, I think it could be a model for Pd libraries in general.
well, i don't see a reason why it should not work well. the biggest problem is probably to find a way where the objects will search for the search-lib (if you don't want to put it into a standard place like /usr/lib/ or /usr/local/lib)
The libtkwidget.so would be included in the libdir to make it a simple package.
