Envoscale

One language for everything you build.

EnvoL is a programming language, and EnvoScale is everything around it in one place: the compiler, the standard library and the envo tool. Command-line programs, servers, apps, websites, graphics and AI, with no third-party code anywhere.

_{EnvIDE drawing itself: the sidebar, tabs, editor and status bar are EnvoUI, the pixels and fonts are EnvoR}

use alloc.text;

interface IShape {
    i64 Area(in this);
    str Name(in this);
}

struct Square : IShape {
    i64 Side;

    public i64 Area(in this) => this.Side * this.Side;
    public str Name(in this) => "square";
}

// One copy of Describe per type it is called with: no virtual calls.
void Describe<T>(in T shape) where T : IShape {
    string line = string.From(shape.Name());
    line.Append(": ");
    line.Append(text.Int(shape.Area()).AsStr());
    print(line.AsStr());
}

Describe(new Square { Side = 4 });

$ envo run .
square: 16

Every example runs in CI, as a script and natively, against the output its README shows.

Every image here was made by EnvoScale itself: screenshots of its website, or pixels rendered by its own libraries.

_{3D with envor.render3d: physically based shading on the CPU, the same pixels on every platform}

_{Native UI with EnvoUI and envor.theme, light and dark, both WCAG AA}

_{The same card in a terminal  ·  2D with envor.gfx and envor.font}

_{The website is an EnvoL program  ·  The sandbox runs the compiler itself in your browser}

A seed of readable hex builds an assembler, which builds a compiler written in assembly. Each later compiler is written in more of EnvoL and built by the one before it, until the compiler builds itself. That chain lives in EnvoScaleAsm, whose CI publishes the seed compiler EnvoLang starts from, only when Linux and Windows built the same bytes.

In the works: making EnvoL's generated code as fast as Rust's, measured by timing the same compiler written in both, and EnvOS.
