RxEnv

Tools for your ARexx development environment

Background

Coding in ARexx on the Amiga can be great fun. It's a quirky little language by modern standards, nevertheless I find it to be a highly enjoyable experience. Still, ARexx was born in 1987, and it lacks many of the comforts we take for granted when working with younger scripting languages.

I've always felt that it's suffered greatly from the inability to include other scripts, allowing the programmer to build a small library of functions that can complement the built-ins. I also frequently miss a Read, Eval, Print Loop.

The best way to remedy this is of course to solve the problem yourself. The development process is described in greater detail here.

The ARexx REPL

The REPL supports multi-line statements (so called "buffers"), will automatically print the result of any single statement returning a value and traps errors without touching the current variable scope. The REPL itself is written in ARexx and should run on any Amiga capable of running ARexx.

The ARexx Preprocessor

The ARexx preprocessor rxpp allows the inclusion of ARexx "modules" - include files with native ARexx functions - into other ARexx scripts. It doesn't do much more at present, but ARexx includes is what I've been missing for a long time, so I'm pleased. The preprocessor is written in C and requires AmigaOS 2.0 or higher.
