A Codemirror-based editor with *most* modern need-to-haves (e.g. LSP, Copilot, Vim, Remote SSH)

cursor-codemirror

Hello! This is an old version of Cursor based off of the Codemirror text editing component. If you're looking to build your own code editor from the ground-up, this may serve as a useful guide 🙂 Cursor is now based on a fork of VSCodium.

Features

• Standard navigation abilities: file tree, "Command P", ripgrep-based search
• Editing table-stakes: split-panes, tabs
• Deep language server support: intellisense, go-to-definition, code actions, linting, symantic syntax highlighting
• Built-in versions of popular extensions: Copilot, Vim/Emacs keys, (beta) Remote-SSH
• AI Features: auto-generated inline diffs and completions, a ChatGPT-style embedded chat, on-hover documentation suggestions

Development

To get started:

git clone [email protected]:getcursor/cursor.git
cd cursor
npm i

Then, download some non-versioned dependencies (ripgrep binaries and language server js):

./setup.sh # Mac/Linux
./setup.ps1 # Windows

Finally, to run the client:

npm start
