OneFile curates delightful open-source projects that each consist of a single file, highlighting how much you can learn from compact, self-contained code. The collection spans tiny games, utilities, servers, interpreters, and teaching demos where the entire idea fits in one readable source. This “one file” constraint makes every example approachable—you can open it, grasp the full control flow, and experiment without navigating a large codebase. It’s ideal for learners seeking quick wins or for teachers looking for simple yet inspiring demos to showcase concepts. Each entry focuses on immediacy and fun, encouraging copying, running, and tweaking to see results instantly. The list format also makes it easy to discover new languages or paradigms without committing to heavyweight projects.
