PowerMops

Mops, a stand-alone development environment for programming the Macintosh, written by Mike Hore, is a full-featured software with a lot to offer. The software is inspired by Smalltalk and Neon, commercial languages, and is based on Forth with extended object-oriented features, including multiple inheritance, early and late binding, persistent objects, and garbage collection.

Its interactive development environment allows for productive and fluid programming by enabling modification and swift testing of small code segments. Mops comes with a vast class library that supports Smalltalk-like classes, such as containers and standard Mac graphical user interface elements. Furthermore, Mops provides seamless integration of Macintosh Toolbox calls and supports AltiVec and external frameworks such as OpenGL and Mach-O.

Mops includes complete source code and a well-written manual to aid both the novice and the expert. It is also Carbon-compliant and runs under both Mac OS 9.x and all Mac OS X versions released to date. The software uses a subroutine threaded, optimizing Forth compiler, transparent to the programmer, resulting in quick program execution.

Mops has been actively maintained for over seventeen years by the original author, along with a group of dedicated volunteers. If you are looking for something different, even if you thought you never had a reason to try it, Mops might be just what you need.
