    microui

    microui

    A tiny immediate-mode UI library

    ...It follows the immediate-mode pattern, where the interface is rebuilt each frame from application state instead of being stored as a large retained widget tree. The project is intentionally small and gives developers room to add their own controls, rendering backends, and interaction patterns. It is especially useful for tools, games, editors, embedded interfaces, and experiments where portability and simplicity matter more than a complete widget toolkit. The library avoids unnecessary complexity and keeps its scope narrow so it can remain easy to understand, modify, and integrate. It is a strong fit for C projects that need basic UI behavior while leaving rendering and platform details under the developer’s control.

    whenwords

    whenwords

    A relative time formatting library, with no code

    whenwords is a concise, open-source natural language scheduler that helps applications interpret date/time expressions (“tomorrow”, “next Friday at 3”, “in two hours”) in ordinary human language and convert them into precise scheduled events. It combines robust parsing logic with a flexible API so developers can embed scheduling understanding into chatbots, task managers, calendar tools, or productivity apps without building complex date interpreters from scratch. The library handles a wide range of expressions, time zones, and relative references, making it useful across different locales and contexts where users provide unconstrained scheduling input. It also includes utilities to validate, normalize, and format parsed results so applications can reliably present scheduled events and reminders in ways that match user expectations.
