Free platform independent model software for linux

Platform Independent Petri Net Editor project (PIPE) creates and analyses Petri Nets quickly, efficiently, and effectively.

A key design feature is the modular approach adopted for analysis, enabling new modules to be written easily and powerfully, using built-in data layer methods for standard calculations.

Six analysis modules are provided, including Invariant Analysis, State-Space Analysis (deadlock, etc.), and Simulation Analysis and Classification.

PIPE adheres to the XML Petri net standard (PNML). The file format for saving and loading Petri Nets is extensible through the use of XSLT, the default being PNML.

OS Independent Atomic Operations is a project that intends to develop an OS-independent atomic operations macro library with a common API for the C programming language as a cross-platform alternative to the uncoordinated efforts by OS developers.
As multi-core CPUs and multi-processor computer systems become more and more common, efficient synchronisation between concurrent execution units becomes more important. Atomic operations, that is operations which cannnot be interrupted, are needed to implement semaphores, reference counters and lock-free algorithms.
Operating systems generally provide atomic operation macros but there is no common API and no coordination between vendors and developers of different systems. Thus library and application developers are facing a dilemma. They can take advantage of one of the existing APIs for atomic operations but their software will then be tied to a particular operating system.
Enhancements:
- The initial release contains the Common AO API draft and a skeleton macro library.
- To complete the macros, the project will need contributors with inline assembly skills for various CPU architectures.

OpenInput project is a cross-platform, easy-to-use, portable input handler library, written in C.
The primary goal of OpenInput is to make it easier for application programmers to write portable code that deals with input from mice, keyboards, joysticks and other devices.
In other words, OpenInput will allow you to write a single piece of code that handles input for your application for all platforms, for example GNU/Linux, Windows and MacOS X.
This is achieved by abstracting the low-level platform-specific input device handling into a stable, intuitive, platform-independent API: OpenInput.
Main features:
- Total platform independence
- Easy to use, sane and simple API
- Fully documented functions and data structures
- Automatic configuration of available devices
- Generic event handling
- Keyboard state managment (eg. up/down/lock)
- Mouse motion and state managment (eg. movement, buttons up/down)
- Joystick motion and state handling for axes, hats and trackballs
- Can "hook" into existing windows
- Provides resize, iconify, close and expose events for the application window
- Action mapping, so events can be handled without any knowledge of the underlying device
- Pointer (mouse) grabbing inside window
- Show/hide pointer inside window
- Keyboard focus grabbing
Enhancements:
- This version contains major documentation updates, both big and small bugfixes, and minor feature enhancements which dont break the API.

The txObject Python Modules provide an interface to the txObject Application Tool Kit and Libraries. txObject ATK provides both embedded and application level projects a five-layer framework. Each layer offers a unified set of tools that allows programmers to focus their development efforts.
A correlation can be made between txObject ATK and Sun Microsystems Inc. Java Language. txObject ATK has many of the advantages Java has, but without some of the performance issues commonly associated with the Java Language. Javas initial advantages are its platform independent built-in and publicly available support libraries. Due to the basic nature of Java, its libraries have a common object-oriented feel and data flow model. txObject ATK has accomplished a similar Java-like environment for C++.
Another correlation can be made between txObject ATK and the CORBA Standards. As demand increases for applications to run in distributed environments and on multiple platforms, projects have had a new added complexity to their traditional development cycle. txObject ATK greatly decreases such complexity in a similar way CORBA does but with two fundamental differences. The first distinction is that txObject ATK is a tightly coupled peer-to-peer distributed system, where CORBA is a loosely coupled client-server model. The second division is that txObject ATK distributed objects are state and transaction consistent. CORBA provides distributed object interfaces without state.
txObject ATK is ideal for developing embedded applications. It has been optimized for memory and CPU constrained systems. The entire software package is comprised of 5,000 lines of class declaration code and 10,000 lines of implementation code. Further reading shall account for the size of each layer.
Each layer of the txObject ATK is a foundation for every successive layer. In order for a particular layer to operate, it requires the layers below it but not the ones above. Since layer 1 is the base for all other layers, close attention should be paid. Each component in layer 1 will be used intimately throughout layers 2-5.
Main features:
- Layer 1 - Object Library
- Layer 2 - I/O & Timers
- Layer 3 - Object-Oriented Threads
- Layer 4 - Inter-Process Communication
- Layer 5 - True Distributed Object Comm. (Object Replication)
