pdj - java plugin interface to pure-data
###########################################################################
RELEASE 0.8.3 / September 2007
PDJ enables you to write java code to interact with pure-data objects. The
API is totally based on Cycling74 Max/MSP 'mxj' object implementation. This
will enable java mxj objects to run on pure-data with pdj. You can also
create signal/tilde (~) objects.
This is a work in progress and some of features are missing and some might
not even be ported.
IMPLEMENTED:
* MaxClock 100%
* MSPBuffer 100%
* Callback 100%
* MaxObject 100%
* Atom 98%
* MaxSystem 90%
* MaxQelem 90%
* MSPObject 85% (missing signal in/outlet detection)
* MSPPerformable 100%
* MaxPatcher 5%
TODO:
* MSPObject connection status
* MaxBox/MaxPatcher object; inspiration from dyn~ (kudo Mr. Grill!)
LIMITATION:
* Signal inlets cannot be hot inlets for receiving atom message.
This means that if you create a signal inlet and send an atom
to this inlet, pdj won't be able to process it; float or symbol.
This looks like a work as designed in pd.
BUGS:
* OS X: cannot use AWT classes with OS X because of a weird bug
that locks the thread when the GUI libraries are loaded.
-> http://lists.apple.com/archives/java-dev/2004/Mar/msg00910.html
this solution has been tested but the loadLibrary still hang.
WORKAROUNDS:
* on most cases you don't have to put the JVM libs dir to the
LD_LIBRARY_PATH. If you have a UnsatisfiedLinkError, add it
before you start PD.
* on some machines, the System.out redirection can crash PD. If
it is the case, you can disable it in the pdj.properties file;
check the property: pdj.redirect-pdio.
REQUIEREMENTS:
* pure-data 0.38.x or better
* java JDK version 1.4.x or better; use 1.5 if you can !
* works on linux, windows
REQUIEREMENTS FOR BUILDING:
* apache ant 1.6.x or better
* c compiler
INSTALLATION:
* if you are using the source distribution, build it before
-> download java sdk from java.sun.com (unless you are using OS X)
-> download apache ant for ant.apache.org
-> edit file <your platform>-build.properties
-> in the root directory of pdj, run 'ant package'
* add the pdj external (pdj.pd_linux/pd.dll/pd.pd_dawrin) directory
to your pd path (very important on OS X)
* the other files of the original binary directory must be in
the same directory
* double check dist/pdj.properties to be sure that the JAVA
environment parameters are right
* === OS X WARNING ====
I am working on a universal binary of pdj. This is planned on version
0.8.4. If you really need a OS X build, email me.
USAGE:
* put your .java file in the /classes directory
* create a pdj object with the name of the java class; if
you have not compiled it before, pdj will do it for you
CHANGELOG:
--- VERSION 0.8.3 ---
* Atom.getInt() on a float now works.
* corrected some classpath definition issues with windows
* bypass the java compilation with pdj.compiler=null
* remove dependencies task for cpptasks.jar (now part of distribution)
* FIXED: comment on property pdj.vm_args failed to initialize VM
* BUG: cannot link with OS X and cpptasks. Planned on 0.8.4
--- VERSION 0.8.2 ---
* if javac is set, using the javac compiler from the JAVA_HOME first
* optimizations (main thread JVM and symbol method resolution)
* FIXED: using pdj.classpath with directories
* FIXED: search path on file in the current directory
* FIXED: leak with open_path and casting warnings
* build for Intel Mac
* getting better at attribute support
--- VERSION 0.8.1 ---
* added MaxPatcher object to get patch path
* FIXED: to match mxj: method with args[] will always be called first
--- VERSION 0.8 ---
* pdj~ object support (MSPSignal/MSPObject/MSPPerformable)
* The JVM can now be server or in client mode (windows/linux only)
* JVM selection for OS X
* FIXED: working jikes compiler on OS X
* FIXED: declareIO inlets count
* FIXED: windows: System.out CR/LF errors on the PD console
--- VERSION 0.7.1 ---
* OS X support with distribution
* FIXED: MaxSystem.locateFile now works
--- VERSION 0.7 ---
* Better JVM resolution on win32 (eg: with the registry)
* Full implementation of MSPBuffer
* Added Atom methods with unit tests
* Windows binaries distribution
* FIXED: now filtering { and } with post() not to lock PD
* FIXED: anything gets called on a undefined bang/float/list method
* FIXED: defined inlet(int) without inlet(float) now works... :-\
--- VERSION 0.6.1 ---
* FIXED: outlet(Atom) and outlet(Atom[]) resolution error
--- VERSION 0.6 ---
* MaxObject constructor with arguments
* partial attribute support; automatic field setter/getter
* added method bail on MaxObject
* strict declaration of inlets/outlets (with info outlet)
* System.out and System.err linked to the pd console
* outlet(atom[]) checks type before calling the right func.
--- VERSION 0.5 ---
* method inlet resolution (bang->float->list->anything) now works
* windows support (premilinary support)
* auto-compiling class of every .java in /class (max -1; pdj +1)
--- VERSION 0.4 ---
* more javadoc and documentation... but could be better
* multiple inlet operations
* loadbang now works
--- VERSION 0.3 ---
* added a small and cheap javadoc. the original MXJ should be the
reference.
* partial MSPBuffer support
* Atom and MaxObject now supports Atom arrays
--- VERSION 0.2 ---
* added classpath of $PDJ_HOME/classes and $PDJ_HOME/lib/* by default
* 95 % Dynamic JVM resolution with the JAVA_HOME; via dlsym (see BUGS)
* MaxSystem.deferLow(...) works ! :-\
* added an help patch
THANKS:
* Thomas Grill
* patrick a 11h11
* pd-mtl crew !
