abcl

The abcl programming language, also known as Armed Bear Common Lisp, is an implementation of the Common Lisp programming language. It is designed to be highly interoperable with Java, allowing Lisp code to call Java code and vice versa. abcl runs on the Java Virtual Machine (JVM), which means it can be used on any platform that supports Java.

abcl provides a robust environment for developing applications using the Common Lisp standard. It supports many features of the language, including macros, closures, and object-oriented programming through the Common Lisp Object System (CLOS). Its integration with Java is a key feature, enabling developers to leverage the vast libraries and existing codebases available in the Java ecosystem. This interoperability can be particularly useful for projects that require both the flexibility of Lisp and the performance or platform support of Java.

The project is open-source and has been developed by a community of contributors. It is often used in academic research and for developing complex software systems where Lisp's expressive power is beneficial. Installation and usage typically involve standard Java development tools and environments. abcl continues to evolve, with ongoing efforts to improve its performance, compatibility, and feature set.
