Lushous is an initiative to develop two main Java oriented components for Lush. The first component, JLush, will implement inline Java usage in Lush (like CLush does for C). LushJ, the second component, will be a Java based implementation of Lush.

This project will also serve as a repository for various Lush scripts, code, and documentation that are not part of the main Lush development.


What is Lush?

Lush is a Lisp-like language with a number of advanced and powerful features that are difficult to find in many other programming languages. At once it provides an interpreted programming environment that is well-suited to rapid application development, prototyping, and testing and also provides compiled code for increased execution speed where necessary. Both interpreted and compiled code can be combined advantageously for demanding computing applications that cannot be satisfied by using interpreted or compiled code alone.

What makes this combination possible is that Lush is actually two different languages in one. The standard Lush act as a Lisp interpreter read-eval-print loop. CLush (Compiled Lush) is the compiled language part of Lush that takes direct advantage of the standard C API and GNU tools to generate object code that can be executed from within Lush.

What is more, Lush also has some amazing builtin capabilities and addon packages that can be used in high-end research and development. Lush features a multidimensional array/matrix engine for working with scalars, vectors, and tensors. It has a dynamic loader for working with C libraries on-the-fly. Various packages for machine learning, machine vision, neural networks, signal processing, audio, video, and more are included. Wow! Good luck finding the same capabilities automatically part of another language.

What will Lushous do?

Just like CLush, with JLush Lushous will bring the same functionality for the Java programming language that is already avaialble for C/C++ in Lush. This is a natural extension for Lush because Java is now very popular and there are many libraries that can be taken advantage of by this addon. There could also be the possibility of mixing standard Lush with JLush and with CLush in various combinations that would more difficult otherwise.

As for LushJ, this will be a ground-up implementation of Lush on top of Java, as opposed to C. Initially, LushJ will only support Lush scripts and Java. Eventually, ways for interacting with standard Lush for interoperability or use of CLush will be investigated. Direct use of C via JNI could be a possibility, but leveraging CLush seems like a more appropriate method to connect to C at this time. Users will be able to use LushJ on any Java supported platform, thereby extending Lush to different platforms without the need for certain tools and libraries to be installed that are needed by standard Lush. This also means that there will be no need for users to compile LushJ as there is for Lush, this makes it easier for users to get started programming in Lush without being concerned for compilers and libraries beyond having Java installed.

The Lushous project welcomes volunteers to participate in its development. The project needs various types of assistance: software developers, documentation writers, translators, packagers, and so on. For software development some knowledge in a few of the following is needed: C/C++, Java, Lisp, Lush, and associated development tools. If you are interested, please contact the project manager Raymond: Martin.
