Re: [kepler-dev] starting an Actor IO package
Hi Jianwu, make sure you're in the ptII-swt directory. that error occurs when you run maven in a directory that doesn't have a pom.xml the os info should be fine for the original pom.

starting an Actor IO package
I've started doing a bit of work on building an actor IO package ( ptolemy.actor.io) The purpose of this is to provide user input and output for actors so that the actors themselves don't have to be responsible for how they get user input, or how output is displayed. This will help to build actors that are useable in gui and headless environments without having to have modified actors for each situation. I've built a simple prototype which uses an IO factory which is embedded in the Manager (since all actors can get access to the manager which controls them). When an actor requires an IO device it makes a request to the IO factory which returns an instance of the desired device. For example, the Display actor requests a Text-based output device. This device implements a standard text based output device interface which has a write(String) function, and all the Display actor has to do is write the text to the device which handles how to display it. I've used spring to instantiate the correct IOFactory so that in the case of vergil, each manager is loaded with a ptolemy.vergil.io.VergilIOFactory and if vergil is not used the manager defaults to a ptolemy.actor.io.HeadlessIOFactory. My work is currently stored in my ptII git mirror, in a branch which has been converted for maven compilation. If you want to clone the whole repository here are the git commands to clone the repository and to get to the branch (this will take a while): git clone git://git.hpc.jcu.edu.au/jc124742/ptII.git git checkout -b actorio origin/actorio or you can download the current snapshot of the branch (which is about 35mb) from: http://www.hpc.jcu.edu.au/git/?p=jc124742/ptII.git;a=shortlog;h=refs/heads/actorio you can then run it by doing: mvn compile # compiles the code, may take a while the first time while maven sorts out it's dependencies mvn exec:exec # starts vergil then fire up any workflow while uses a Display actor. Note that i'm rubbish with swing and some of the window placing/sizing functionality has been removed to facilitate the separation of the actor from the visualisation, so the display window isn't nearly as good as the old one. If you start the workflow using MoMLSimpleApplication (i.e: mvn compile java -cp target/classes:$HOME/.m2/repository/org/springframework/spring-context/2.0.8/spring-context-2.0.8.jar:$HOME/.m2/repository/org/springframework/spring-beans/2.0.8/spring-beans-2.0.8.jar:$HOME/.m2/repository/org/springframework/spring-core/2.0.8/spring-core-2.0.8.jar:$HOME/.m2/repository/log4j/log4j/1.2.15/log4j-1.2.15.jar:$HOME/.m2/repository/commons-logging/commons-logging/1.1.1/commons-logging-1.1.1.jar ptolemy.actor.gui.MoMLSimpleApplication ../test.xml ) it will print the output of any Display actors to the console. If other people want to work on this, I will create a new branch for it on the ptolemy II svn (it requires a few changes to the core of ptolemy so i'm not gonna commit it to the trunk) and put it there in makefile building mode. So, is anyone else interested in this? I think it's a key component in making kepler available in multiple environments. But it's a big change, much too big to be left up to one person. I would feel a lot more comfortable with a bunch of people telling me my ideas and designs are rubbish and help me build a good system rather than to build something that no one but me wants to use. Things that need to be done: * My factory idea and prototype architecture needs to be criticised. * Types of devices need to be defined (i.e. text output, image output, file output, graph output, etc) * IO Factory and device interfaces need to be defined. * Existing actors need to be modified to use the factory. * standard factory implementations need to be written (i.e. I'm rubbish at swing and thus someone else should do the vergil factory). Comments? Ideas? Criticisms?
