Rebol ( ; historically REBOL) is a cross-platform data exchange language and a multi-paradigm dynamic programming language designed by Carl Sassenrath for network communications and distributed computing. It introduces the concept of dialecting: small, optimized, domain-specific languages for code and data, which is also the most notable property of the language according to its designer Carl Sassenrath:

Source code

This first release is intended for non-Windows systems like Linux, Mac, BSD, Android, etc. However, it will build for Windows, but I've not included the typical MSVC project files. I'll try to get that added, but it's not that tough to create one yourself. You will need to set struct align to 4 bytes. You might notice that the makefile is a bit old-fashioned. That's because I still support Rebol on some very old systems that don't offer newer makefile features. So, please keep that in mind and stick with this simple format. Also, the makefile is built by Rebol. Typing "make make" will rebuild it, and you can also select a different platform target by providing the Rebol platform identifier typing e.g. "make make OS ID=0.4.4" (Linux Libc6 2.11 platform version). The build happens in the make directory. It will create an obj sub-dir for storing the object files. I prefer this over mixing the source and object files into the same directory. If you are building for a new platform that has no existing Rebol, you can use "make prep" to build all the files you need on an existing platform and copy them to the new platform. After the prep, just run "make" or "make r3" and the rest of the system will build. Rebol builds on many different compilers over a range of systems. Although the C source doesn't strictly follow any one standard, it's quite portable and I've yet to find a toolchain that won't build it. You can even cross compile it for embedded systems quite easily. If you run into a problem, it's probably something fairly simple. Don't over complicate it. I welcome your help with porting Rebol to many more devices and making various improvements. I just ask that you: 1. Keep code clear and simple. 2. Document unusual code, reasoning, or gotchas. 3. Use same style for code, vars, indent(4), comments, etc. 4. Keep in mind Linux, OS X, BSD, big/little endian CPUs. 5. Test everything, then test it again.

Rebol ( ; historically REBOL) is a cross-platform data exchange language and a multi-paradigm dynamic programming language designed by Carl Sassenrath for network communications and distributed computing. It introduces the concept of dialecting: small, optimized, domain-specific languages for code and data, which is also the most notable property of the language according to its designer Carl Sassenrath:

Douglas Crockford, known for his involvement in the development of JavaScript, has described Rebol as "a more modern language, but with some very similar ideas to Lisp, in that it's all built upon a representation of data which is then executable as programs" and as one of JSON's influences.
