labelle-sdl

The SDL2 rendering backend for the labelle 2D engine, as an out-of-tree pluggable backend (labelle-assembler#386).

Desktop-only, loop-style. SDL2 window + SDL_Renderer; gamepad via SDL's GameController API; audio via SDL_mixer.

Use it

.backend = .sdl,
.backend_package = .{ .name = "sdl", .repo = "github.com/labelle-toolkit/labelle-sdl", .version = "0.1.0" },

(With the default-flip, .backend = .sdl resolves here automatically.)

Layout

• src/ — the four backend modules: gfx, window, input, audio
• backend.manifest.zon + build_fragments/ — drive the assembler's manifest-splice codegen
• templates/desktop.txt — the generated run-loop
• build_helpers.zig — SDL link/discovery helpers (host-tested)
• example/ — a standalone SDL demo

Build

zig build test          # host + backend tests (needs SDL2 + SDL2_mixer)
cd example && zig build  # the demo
