A Prototype of 3APL Interpreter.

A Prototype of 3apl Interpreter

The prototype of 3APL interpreter is written in haskell and developed by Daan Leijen. It is created to experiment with experiment with new features of 3apl, like complex goals, agent communication, and agent planning. As a prototype system, it does not implement full 3apl specification yet and it lacks some features with respect to the Java release:

No nice graphical environment but a simple command line interface.
Just bare-bone prolog support, i.e. no floating point, strings, libraries etc.

However, it has its own interesting features too:

Supports for planning and reflection, i.e. execute and examine goals dynamically.
Supports for arbitrary external components, written in your favorite language. Windows distribution ships with the super graphical agent cartoon characters.
Multiple, concurrent, communicating agents.

Binary distribution [ windows (~558k)]
A pre-compiled interpreter including sources, demos, the agent component, and documentation. Please tell me when your favorite platform is not included here and we will try to add it. Unpack in a suitable directory, for example c:\3apl. It is highly recommended to read the user guide: doc/intro.pdf. The interpreter is started as bin/triple-apl. Don't forget to set the environment variables:
- APLPATH -- the search path for .3apl files. Should at least include: c:\3apl\demo.
- PROLOGPATH -- the search path for .pl (prolog) files. Should at least include: c:\3apl\prolog.
On windows, the environment variables can be set by clicking: "start/settings/control panel/system/advanced/environment variables". Windows users might want to download the Microsoft agent component to run all demos. Go to the agent website and install the characters: merlin, robby, genie and peedy. Also install the Lernout&Hauspie TruVoice text-to-speech engine.

Source distribution [ zip (~273k)]

The interpreter sources, demos and documentation. Unpack in a suitable directory, for example c:\3apl. There are three ways to run the interpreter:
- Type "make release". This only works when you have the glasgow haskell compiler installed (which is normally not directly available on most platforms).
- Run the glasgow haskell interpreter, type "runghci". This only works when you have the glasgow haskell compiler installed. (On windows platforms, you must have compiled the interpreter at least once in order to generate some essential .o files).
- Use the hugs interpreter, type "hugs src/Main.hs". Unfortunately, the hugs interpreter doesn't support external components but is otherwise fully functional. You have to set the search path within the Hugs interpreter to the source files: src/common/hugs:src/common:src/parsec:src/prolog:src/3apl:src

User guide [ pdf (~131k)]

A short user guide to the interpreter. Also included in the main distribution.
