Pd Documentation chapter 4: writing Pd objects in C

- -

- back to table of contents -

-

- -

You can write your own objects that you and others can use in their Pd -applications. You can write them in C or (if you're smart and brave) in C++ or -FORTRAN. - -

HOW EXTERNS ARE LOADED - -

Whenever you type the name of an object -(into an "object" text box) that Pd doesn't yet know about, Pd looks for a -relocatable object file, named, for instance, "profile.pd_irix5". Pd looks -first in the directory containing the patch, then in directories in its -"path." Pd will then add whatever object is defined there to its "class list," -which is the set of all Pd classes you can use. If all this works, Pd then -attempts again to create the object you asked for, this time perhaps -successfully. There is no difference between an object defined this way and an -object built into Pd. - -

Once you load a new object into Pd, it's there for the duration of your Pd -session. If you load another Pd document which supplies a different version of -some Pd object, the object won't be updated. IF you're working on a new object -and decide to change it, you have to exit and re-enter Pd to get the change to -take. - -

In the "externs" subdirectory of the documentation you -can find simple examples of "externs" with their source code and test patches; -there are many other on the web (see section 1.2 ). - -

Iohannes Zmoelnig has written an excellent guide to writing externs at - - http://iem.kug.ac.at/pd/externals-HOWTO/ . - -

A paper by Theo Stojanov on the subject is at: - -http://www.music.mcgill.ca/~theo/html/audio/pd_externs.pdf . - -

NT HINT: In NT, Pd is compiled using Visual C 6.0. If you have VC 5.x -your externs won't compile against Pd; you'll get an error about "disk full -or bad DLL." Simply recompile Pd under 5.x and the problem goes away. Externs -compiled under 5.x and 6.x are binary compatible; it's just the compilation -that's sensitive. - - - -- cgit v1.2.1
