EnvoL

A programming language that compiles to small native programs for Windows, Linux, macOS and the browser. One tool, envo, builds, runs, tests, formats and packages it. The compiler, the standard library and the tool are written in EnvoL, with no third-party code.

enum Shape {
    Circle(i64 radius),
    Rect(i64 width, i64 height),
}

i64 Area(in Shape s) => match s {
    Circle(r) => 3 * r * r,
    Rect(w, h) => w * h,
};

List<Shape> shapes = List<Shape>.New();
shapes.Push(Shape.Circle(2));
shapes.Push(Shape.Rect(3, 4));

i64 total = 0;
foreach (var s in shapes.AsSlice()) total += Area(s);

Install

Download a release, or build from source with only Git and a shell:

git clone https://github.com/envoscale/EnvoLang
cd EnvoLang
./build.sh build                  # or .\build.ps1 build in PowerShell
build/envo/envo examples/00-hello/main.envol

The documentation for EnvoL and every project around it is in EnvoScale: getting started, a tour of the language, and the envo commands. Here: examples/ and the specification.

The compiler compiles itself. The first compiler comes from EnvoScaleAsm, which builds it from assembly.
