A modular C++ 2D engine for embedded displays and desktop, with a visual editor. This site documents the engine core and its C++ API; every package documents itself on its own site, linked below. All of it is generated from the code (engine 1.3.0).

Engine core: components and settings the engine provides itself
Project settings: every settings section, by owner
API reference: the C++ classes of the engine and the editor DLL
Editor repository: setup, contributing, compatibility policy

Packages

Each package is its own repository under github.com/dekiengine and is installed with DekiEditor --packages-add <id> <project> or the Package Manager.
