Open Source Interpreters

X11-Basic is a dialect of the BASIC programming language with graphics capability that integrates features like shell scripting, cgi-Programming and full graphical visualisation into the easy to learn basic language on modern computers.

ScummVM is a cross-platform interpreter for many point-and-click adventure games. This includes LucasArts SCUMM games (such as Monkey Island 1-3, Day of the Tentacle, Sam & Max, ...), many of Sierra's AGI and SCI games (such as King's Quest 1-6, Space Quest 1-5, ...), Discworld 1 and 2, Simon the Sorcerer 1 and 2, Beneath A Steel Sky, Lure of the Temptress, Broken Sword 1 and 2, Flight of the Amazon Queen, Gobliiins 1-3, The Legend of Kyrandia 1-3, many of Humongous Entertainment's children's SCUMM games (including Freddi Fish and Putt Putt games) and many more.

SmallBASIC is a fast and easy to learn BASIC language interpreter ideal for everyday calculations, scripts and prototypes.

MANTIS is a hybrid high level programming language and tools optimized to crank out "line of business" applications. It allows focus on business data and process instead of technology. However, access to low level technologies are available if desired.

Java library for parsing and evaluating math expressions. Javadoc is available at http://bracer.sourceforge.net/javadoc/ P.S. This library depends on Apache Commons Math, so don't forget to include commons-math-2.2.jar to your project.

N.B. THE PROJECT HAS BEEN MOVED TO GITHUB https://github.com/jiprolog/ JIProlog is a cross-platform pure Java 100% Prolog interpreter that integrates Prolog and Java languages in a very fashinating way. JIProlog is compliant with the major Prolog interpreters. It supports most of ISO Prolog specifications and the most common and used built-in predicates, JIProlog allows to call Prolog predicates from Java without dealing with native code (JNI or JNA) and allows to invoke Java methods from Prolog in the same way you call predicates.

MANOOL is a practical, homoiconic, dynamic, multiparadigm general-purpose programming language with a functional core. It has high expressive power but is implemented in less than 10K LOC of optimized, idiomatic C++11 for native run-time environments. MANOOL is meant to compare and compete directly with Python, PHP, Ruby, Perl, and Tcl, although incidentally it has some combination of unusual features. Example: {{extern "manool.org.18/std/0.2/all"} in WriteLine[Out; "Hello, world!"]} Explicitly stated design priorities of MANOOL: 1. implementation simplicity; 2. expressive power, usability, and general utility, attention to syntax and semantics details; 3. correctness, security, and overall quality of implementation, run-time reliability; 4. run-time performance and scalability; 5. consistency, completeness, orthogonality of features, and language elegance, conceptual economy and purity. MANOOL strives to satisfy all of the above goals, better than existing alternatives!

embeddable scripting language

jWAM is a 100% Java Warren Abstract Machine implementation. Currently it is still under development though all the basic functionalities (compiling, resolution) are working. As far as I know this is the only open source Java based implementation out there that does not simplify Warren's design. I have done some comparison's with other Java based Prolog engine's and jWAM does seem to outperform them all quite well (tuProlog, JLog, JIP, jTrolog). However, if you need a Java based Prolog engine for your project I recommend tuProlog and jTrolog as they are at the moment way more mature than jWAM. Most notable to-do's: - Built-in predicates. - Debugging tools. - Testing. - Documentation and commenting. - Android port. (I have the engine working with a test app but I still need to build a proper app). - Alpha release
