Open Source Java Compilers

Tsunami is an open-source high performance computing language. With it you can write streaming data-parallel algorithms that utilize GPGPUs for orders-of-magnitude speed-up with the ease of writing sequential algorithms.

Important: Groimp migrates to Gitlab. You can find the latest code at "https://gitlab.com/grogra/groimp/". The version on Sourceforge will not be updated anymore. The modelling platform GroIMP is designed as an integrated platform which incorporates modelling, visualisation and interaction. It exhibits several features which makes itself suitable for the field of biological or ALife modelling: The “modelling backbone” consists in the language XL. It is fully integrated, e.g., the user can interactively select the rules to be applied. GroIMP provides classes that can be used in modelling: Turtle commands, further geometrical classes like bicubic surfaces, the class Cell which has been used in the Game Of Life implementation, and so on. The outcome of a model is visualised within GroIMP. In the visual representation of the model output, users can i

The CodeTime platform covers every aspect of parallel software from authoring, through distribution, to run-time. Its goals are: high programmer productivity; write once, run high performance anywhere; and wide acceptance.

A Controlled Language Programming (CLP) compiler, runtime engine, and development IDE for writing software in a natural (but somewhat restricted) language that clearly represents the real world concerns and maps to a 3GL (Java/Groovy) for execution.

ECL is a system-level specification language for HW/SW designs and is based on Esterel and C. The ECL compiler parses ECL, writes Esterel and C, and uses the Esterel compiler to produce an implementation. Originally developed at Cadence Berkeley Labs.

EXTE recognizes temporal expressions in a text. Temporal expressions are any references to the TIME e.g.: "today", "12th march 2006", "as soon as he woke up". This analyzer will recognize three languages: Spanish, English and French.

GELLO is an ANSI-accredited HL7 standard for creating computable, unambiguous clinical queries. This project creates an open source compiler and client-server IDE. Projects are stored in a subversion repository, and created by the RCP based client.

JSim8086 is platform-independent Assembly Language Simulator of the Intel 8086 CPU. It was designed to be a learning tool (CAL) for first year Computing students who are learning Computer Systems Organisation and Assembly Programming.

JUndo is a declarative object-oriented programming language with functional, and intensional programming characteristics. Applications include multi-level undo and sophisticated error recovery. See http://verdantium.blogspot.com/

Runtime library for the JUndo language. See http://verdantium.blogspot.com/

JPIE is an implementation of an Open Source Java to Prolog/Prolog to Java interoperability mecanism based on the Java VM.

This project aims to implement an LC2/LC3 assembler and simulator for the Linux and Windows platforms.

M+ Compiler/Interpreter is a interpreter library written in Java that delivers the possibility to extend any Java application with simple scripts. Besides the usage of native datatypes and operations you can instantiate and call native Java objects.

NXTAssembler is an assembler for the Lego Mindstorms NXT.

OpenL implements Java-like languages allowing to use code snippets placed in Excel, XML, or DB. OpenL is a foundation for OpenRules http://openrules.com. Maintained from http://openl.org

PHDL is an HDL that functions as an alternative to mainstream graphical schematic capture tools. The language is compiled into a pcb netlist which can then be imported into a layout tool. We are currently on version 2.1 of the tool. We have created an eclipse plugin version of the tool as well as a standalone command-line based version. Both function identically and output a netlist that can be imported into a pcb layout tool. VHDL revolutionized how FPGA designs and digital logic circuits have been designed and captured and overcame many of the difficulties associated with the use of schematic editing tools. We believe the use of an HDL is also the way of the future when it comes to PCB design. The PHDL compiler automatically supports the output of PADS and Eagle netlists, and through extending a simple java class, users can generate a netlist in practically any format required by their choice of a layout tool.

parsing simulator can be used to determine first ,follow , nullable and can be used to calculate LR items.

RunCC is a new kind of parsergenerator that generates parsers and lexers at runtime. Source generation is only optional. It features the absence of any cryptography. Although intended for small languages, it comes with Java and XML example parsers.

The SrcML Framework allows converting Sourcecode to a XML representation on which tools can then be used to deduce statical data for analyzing and visualizing the initial source. It also provides easy ways to write programs which modify other programs.

The VSR is a repository of tools and challenges in verification (see for example epubs.cclrc.ac.uk/work-details?w=33971). It is part of the international grand challenge on software verification (eg http://vstte.ethz.ch/pdfs/vstte-hoare-misra.pdf)

UfakPython is a small subset of Python programming language, for small embedded devices, like PICs. UfakPython sources are translated to C by UfakPython Compiler. Small Device C Compiler can then compile the C outputs to the target device's codes.

Visai Neri is an attempt to syntactically parse Natural Languages in general and Tamil in particular. To this end, we have developed an application using JavaCC to parse Venpa poetry after writing the grammar in BNF. Vision: complete Tamil grammar in

WSGRD stand for Web Service Grid Resource Discovery. When using Grid Computing, one of the problem is to find resources dynamically. WSGRD tries to address this problem using web services.

Chasm-interop is a set of tools that parses C++ and Fortran 90 source files and automatically generates bridging code to provide for seamless language interoperability.

The compilerMonitor persists a record of all javac error messages and the sources that caused/fixed the errors. It is a CAUSE (computer-aided usability engineering) tool that analyzes interaction between a developer and the compiler.
