Wat

Wat provides a command‑line interface that aggregates community‑generated cheat sheets, API references, readmes, code snippets and usage examples for a wide range of programming languages and libraries. By indexing this material and applying edit‑distance matching, auto‑completion and usage‑based optimization, the tool returns concise answers to syntax and usage queries directly from the terminal.

The project targets developers who need quick, practical documentation without leaving their CLI workflow, especially for popular JavaScript and Node.js ecosystems. It is designed for rapid installation, short learning time and easy contribution, allowing users to add or improve content that is then auto‑updated for the whole community.

Wat is open source, stable and available as a global npm package, and it continuously incorporates new community contributions to expand its coverage of languages and frameworks.
