codemirror-vim

Vim keybindings for CodeMirror.

This is a pnpm workspace containing three packages:

• @replit/codemirror-vim — Vim keybindings for CodeMirror 6 (the main package)
• cm5-vim — the same vim engine bundled for CodeMirror 5
• @replit/codemirror-vim-core — the editor-agnostic vim engine and shared test suite used by both, originally authored by @mightyguava (Yunchi Luo)

Development

pnpm install
pnpm run dev      # start the CodeMirror 6 demo
pnpm run test     # run the CodeMirror 6 test suite
pnpm run testAll  # run all tests, including cm5 and packaging checks

The repo ships a nix dev shell via direnv: direnv allow provides node, pnpm, and the browsers needed for tests.
