Hey, We're busy with making a beat detector in Pd, but we're stuck in such a way that we want stopped trying to implement it as a patch. We're now skinning our matlab code to make it as fast and small as possible. After that we'll translate it to C code (hopefully the matlab-to-C compiiler helps us a little bit, because we're not so experienced in C programming). And then we'll try to turn it into a Pd external. I already worked through the external tutorial of Zmölnig, but I still have some questions:
- How to use the the x_, a_ and t_ prefixes
- I already understand how to compile and so on, but does anyone know
a good C editor, free and windows (or is that a contradiction?)
- How can we test and compile a 'block' without the main methods or
header files included? Or how do you have to do that?
I fear I'll also have many more questions when we really implement it. Hopefully you guys will help us out very soon. Ronny look at http://idafx.blogspot.com (or Pd webring) for more information
Eclipse is a pretty good IDE written in Java (x-platform), out of the box it's geared towards java but you can get extensions for all sorts of languages, The C extension is called CDT. You would need Cygwin or Mingw to compile with it on windows I guess. More info here: http://www-128.ibm.com/developerworks/library/os-ecc/

* How to use the the x_, a_ and t_ prefixes
use them at your own will...
however: the "t_" prefix are used to denote "this name is a 'type'" (this is: for any type you declare via 'typedef', prefix it with "t_"). other people use other conventions (e.g. by postfixing "_t" to types);
the "a_" prefix usually denotes "element of the 'atom'-structure" (actually of the 't_atom', see above).
the "x_" prefix usually denotes "element of the 'x'-structure" (whatever 'x' means; in miller's (and most derived) code, "x" is the name of the class _variable_ (not the type))
for computers (compilers) you can use whatever, it is really just for humans to make your code more readable.
* I already understand how to compile and so on, but does anyone know a good C editor, free and windows (or is that a contradiction?)
no it is not a contradiction. there is xemacs on windows. probably uedit is good too (haven't used it for years). you might also want to code in notepad, but don't try M$Word.
* How can we test and compile a 'block' without the main methods or header files included? Or how do you have to do that?
why would you? this question seems rather theoritical to me. the usual way to include a header-file is by using the '#include' preprocessor directive ;-)

Better choices for free Windows editors might be CREAM (like vim, but hides advanced stuff behind menus if you want), Notepad++, and ConText.

Are you already aware of aubio, which does this pretty well, and provides PD externals that wrap the functionality? (http://aubio.piem.org/).
Just might save you some time.
best,
Jamie
