immediateij

Immediateij is a programming language designed for immediate mode graphical user interfaces (GUIs). It was created by Casey Muratori as part of his Handmade Hero project, which aims to provide a comprehensive guide to building a game engine from scratch. The language is characterized by its simplicity and minimalism, focusing on low-level control over the rendering pipeline and user input handling.

Immediateij is not a general-purpose programming language but is specifically tailored for creating immediate mode GUIs. In immediate mode GUIs, the application state is updated and the UI is rendered in a single pass, without the need for a separate rendering loop or event handling system. This approach can lead to more efficient and responsive user interfaces, as the application can directly respond to user input without the overhead of a separate event queue.

The language syntax is C-like, with a focus on simplicity and ease of use. It includes features such as basic data types, control structures, and functions, but lacks more advanced features such as classes or inheritance. This minimalistic approach allows for greater control over the rendering pipeline and user input handling, but also requires more manual management of resources and memory.

Immediateij is open source and is available for download from the Handmade Hero project website. It is primarily used for educational purposes, as part of the Handmade Hero project's goal of providing a comprehensive guide to building a game engine from scratch. However, it may also be of interest to developers who are interested in immediate mode GUIs or low-level graphics programming.
