Red Programming Language
Red is a new programming language strongly inspired by REBOL, but with a broader field of usage thanks to its native-code compiler, from system programming to high-level scripting, while providing a modern support for concurrency and multi-core CPU.
The language is in its early bootstrapping phase. The Red/System low-level DSL is the first focus. It is a limited C-level language with a REBOL look'n feel, required to build Red's runtime library. More information on red-lang.org.
Running the Red/System hello script
The compiler and linker are currently written in REBOL and can produce Windows, Linux, Syllable, Android and Mac OS X executables. So, for now, a REBOL/Core binary is required to compile Red/System programs. Please follow the instructions for installing the compiler tool-chain:
Clone this git repository or download an archive (
rebolbinary, put it in
red-system/folder, that's all!
Let's test it: run
./rebol, you'll see a
>>prompt appear. Windows users need to click on the
rebol.exefile to run it.
do/args %rsc.r "%tests/hello.reds", the compilation process should finish with a
...output file sizemessage.
The resulting binary is in
red-system/builds/, go try it! Windows users need to open a DOS console and run
%rsc.r script is only a wrapper script around the compiler, for testing purpose. It accepts a
-v <integer!> option for verbose logs. Try it with:
>> do/args %rsc.r "-v 5 %tests/hello.reds"
Cross-compilation is easily achieved by using a
-t command line option followed by a target ID.
Currently supported targets are:
|Windows, x86, console-only applications|
|Windows, x86, native applications|
|Mac OS X Intel, console-only applications|
|Syllable OS, x86|
For example, from Windows, to emit Linux executables:
>> do/args %rsc.r "-t Linux %tests/hello.reds"
From Linux, to emit Windows console executables:
>> do/args %rsc.r "-t MSDOS %tests/hello.reds"
