• DUB

A flexible, pluggable UI library for the D programming language. Minimal setup. Declarative. Non-intrusive.

auto root = vspace(
    .layout!"center",
    label(
        .layout!"center",
        "Hello World from"
    ),
    imageView("./logo.png"),
);

Fluid comes with Raylib 5 support. Integration is seamless: one or two calls do the job.

while (!WindowShouldClose) {
    BeginDrawing();
        ClearBackground(color!"#fff");
        root.draw();
    EndDrawing();
}

Fluid is largely feature-complete and has successfully been used to produce complete programs like Samerion Studio. It is still receiving incremental improvements to make it easier to use, more accessible, and more performant.

While in pre-release stage, breaking changes are reserved to v0.x version bumps and new features.
