Vim keybindings for CM6

Run on Replit badge NPM version badge

Installation

npm i @replit/codemirror-vim

Usage

import { basicSetup, EditorView } from 'codemirror';
import { vim } from "@replit/codemirror-vim"

let view = new EditorView({
  doc: "",
  extensions: [
    // make sure vim is included before other keymaps
    vim(), 
    // include the default keymap and all other keymaps you want to use in insert mode
    basicSetup, 
  ],
  parent: document.querySelector('#editor'),
})

Note: if you are not using basicSetup, make sure you include the drawSelection plugin to correctly render the selection in visual mode.

Usage of cm5 vim extension api

The same api that could be used in previous version of codemirror https://codemirror.net/doc/manual.html#vimapi, can be used with this plugin too, just replace the old editor instance with view.cm in your code

import {Vim, getCM} from "@replit/codemirror-vim"

let cm = getCM(view)
// use cm to access the old cm5 api
Vim.exitInsertMode(cm)
Vim.handleKey(cm, "<Esc>")

Define additional ex commands

Vim.defineEx('write', 'w', function() {
    // save the file
});

Map keys

Vim.map("jj", "<Esc>", "insert"); // in insert mode
Vim.map("Y", "y$"); // in normal mode

Unmap keys

Vim.unmap("jj", "insert");

Add custom key

  defaultKeymap.push({ keys: 'gq', type: 'operator', operator: 'hardWrap' });
  Vim.defineOperator("hardWrap", function(cm, operatorArgs, ranges, oldAnchor, newHead) {
    // make changes and return new cursor position
  });
