Documentation

Learn OSM.

The official home for learning the language, understanding the compiler, and finding your way around the syntax.

The project documentation is still growing. This page is the first polished structure; the language reference can be expanded as OSM evolves.

Getting started

OSM is transpiled to C. The current workflow uses Rebol for the transpiler and GCC to compile the generated C code.

./r3 boil.r3 myprogram.osm

The current project describes the compilation pipeline as:

.osm source→Parser→AST→IR→C→GCC

OSM follows Meta for most types. The detailed reference can grow here as the implementation settles.

Functions can be user-defined:

add-these: func [
    a [WHOLE!]
    b [WHOLE!]
    /return [WHOLE!]
] [
    return a + b
]

write add-these 10 20

The current language includes IF, EITHER, UNTIL, WHILE, LOOP and REPEAT.
