rhysd/vim.wasm
Vim.wasm
vim.wasm is a full port of the Vim editor compiled to WebAssembly that runs entirely in a browser tab. It provides a complete code editing experience with syntax highlighting, text objects, and all standard Vim features, executing natively in the browser through Emscripten compilation.
The editor integrates deeply with browser capabilities, including drag-and-drop file opening, system clipboard synchronization for cross-application copy and paste, and IndexedDB-based persistent storage that preserves user configuration and edited files across browser sessions. Files can be loaded from URLs via query parameters, and the current buffer can be exported as a downloadable file.
Additional capabilities include an interactive vimtutor tutorial runner for learning editor commands, the ability to execute JavaScript code from within the editor buffer, and terminal emulator canvas rendering that draws the text interface onto an HTML5 Canvas element. The project provides a complete file management workflow within the browser, supporting loading, saving, and managing files without requiring a server backend.
