The error you're encountering suggests that the vim-monaco package is trying to access a property (SelectionDirection) that is not defined or available at the time of access. This could be due to a few reasons, such as an incomplete vim-monaco setup or a missing dependency.

Here are some steps to troubleshoot and potentially resolve the issue:

1. Verify Dependencies

Ensure that you have the correct versions of monaco-editor and vim-monaco installed.

yarn add monaco-editor vim-monaco

2. Modify Initialization Code

Instead of directly initializing VimMode, use the initVimMode method from vim-monaco.

3. Ensure Vite Configuration

Make sure your Vite configuration supports loading these modules correctly. You might need to adjust vite.config.js.

Updated MonacoEditor.tsx

Here is an updated version of your MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { initVimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<any | null>(null);

  useImperativeHandle(ref, () => ({
    focus: () => {
      monacoEditorRef.current?.focus();
    },
    getValue: () => {
      return monacoEditorRef.current?.getValue();
    },
  }));

  useEffect(() => {
    if (editorRef.current) {
      const editor = monaco.editor.create(editorRef.current, {
        value: initialValue,
        language: language,
        theme: 'vs-dark',
        automaticLayout: true,
      });

      monacoEditorRef.current = editor;

      // Initialize Vim mode
      const statusBarContainer = document.createElement('div');
      vimModeRef.current = initVimMode(editor, statusBarContainer);

      editor.onDidChangeModelContent(() => {
        if (onChange) {
          onChange(editor.getValue());
        }
      });

      // Define Vim commands
      const defineVimCommands = () => {
        const Vim = (window as any).Vim;
        if (Vim) {
          Vim.defineEx('w', '', () => {
            if (onSave) {
              onSave(editor.getValue());
            }
          });

          Vim.defineEx('q', '', () => {
            if (editorRef.current) {
              editorRef.current.style.display = 'none'; // Hide the editor
            }
          });

          Vim.defineEx('wq', '', () => {
            if (onSave) {
              onSave(editor.getValue());
            }
            if (editorRef.current) {
              editorRef.current.style.display = 'none'; // Hide the editor
            }
          });
        } else {
          console.error('Vim object is not available on the window');
        }
      };

      // Delay initialization to ensure the editor is fully loaded
      setTimeout(defineVimCommands, 100);

      return () => {
        if (vimModeRef.current) {
          vimModeRef.current.dispose();
        }
        editor.dispose();
      };
    }
  }, [initialValue, language, onChange, onSave]);

  return <div ref={editorRef} className="monaco-editor-container" style={{ height }} />;
});

export default MonacoEditor;

4. Check Vite Configuration

Ensure your Vite configuration can handle the dependencies correctly. Sometimes, you might need to adjust the Vite configuration to handle certain libraries.

5. Debugging

Add some debugging logs to understand the state of the editor and Vim mode when the error occurs.

useEffect(() => {
  if (editorRef.current) {
    const editor = monaco.editor.create(editorRef.current, {
      value: initialValue,
      language: language,
      theme: 'vs-dark',
      automaticLayout: true,
    });

    monacoEditorRef.current = editor;
    console.log('Monaco Editor initialized');

    const statusBarContainer = document.createElement('div');
    vimModeRef.current = initVimMode(editor, statusBarContainer);

To use your forked version of the `vim-monaco` library in your project, you can follow these steps:

### 1. Publish Your Forked Repository
If you want to publish your forked repository to npm under a different name, follow these steps, otherwise, you can use it directly via GitHub.

#### Option 1: Use GitHub Repository Directly
Update your `package.json` to point to your forked GitHub repository.

```json
{
  "dependencies": {
    "vim-monaco": "github:your-github-username/vim-monaco#branch-name"
  }
}

Option 2: Use a Local Path

If you want to use a local path for development purposes, you can use the file: protocol.

  1. Clone your forked repository to your local machine.
  2. Update your package.json to use the local path.
{
  "dependencies": {
    "vim-monaco": "file:../path-to-your-local-vim-monaco"
  }
}

2. Update adapter.ts

Make the necessary changes to adapter.ts in your forked repository.

3. Install Dependencies

Run yarn install to ensure that your project uses the local version of vim-monaco.

4. Verify Changes

Ensure that the changes you made in adapter.ts are being reflected.

Example package.json Configuration

Here's an example of how your package.json might look after pointing to your local fork:

{
  "name": "your-project",
  "version": "1.0.0",
  "private": true,
  "dependencies": {
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "monaco-editor": "^0.28.1",
    "vim-monaco": "file:../path-to-your-local-vim-monaco"
  },
  "scripts": {
    "start": "vite",
    "build": "vite build",
    "serve": "vite preview"
  },
  "devDependencies": {
    "vite": "^2.4.4",
    "@vitejs/plugin-react": "^1.0.0"
  }
}

5. Adjust adapter.ts

Since you're encountering an issue with SelectionDirection, ensure that window.monaco is available when accessing SelectionDirection.

Here's an example of how you might adjust adapter.ts:

/**
 * An adapter to make CodeMirror's vim bindings work with monaco
 */
import { IPosition, IRange, ISelection } from "monaco-editor";
import monaco from "monaco-editor";
import { StatusBarInputOptions, ModeChangeEvent } from "./statusbar";
import { ExCommandOptionalParameters } from "./keymap_vim";
import { Pos, getEventKeyName, makePos } from "./common";

// Ensure window.monaco is available
const SelectionDirection = window.monaco ? window.monaco.SelectionDirection : monaco.SelectionDirection;

export class CmSelection {
  /// Where the selection started from
  readonly anchor: Pos;
  /// Where the cursor currently is
  readonly head: Pos;

  constructor(anchor: Pos, head: Pos) {
    this.anchor = anchor;
    this.head = head;
  }
}

6. Rebuild Your Project

After making the changes, you can rebuild your project to ensure that everything is working correctly.

yarn dev

This setup should help you use your forked version of vim-monaco and troubleshoot the issue with SelectionDirection. Let me know if you encounter any other issues!

You don't need to put your local vim-monaco repo in the node_modules of your handterm project manually. Using the file: protocol in your package.json should work as long as the path is correct and the package structure is valid.

Here are some steps to ensure everything is set up correctly:

1. Verify the Path

Ensure the path to the local vim-monaco repo is correct relative to the handterm project.

2. Package Structure

Ensure the vim-monaco package in your local repo has the correct structure and a valid package.json.

Example package.json for vim-monaco:

{
  "name": "vim-monaco",
  "version": "1.0.0",
  "main": "dist/index.js",
  "module": "dist/index.js",
  "files": [
    "dist"
  ],
  "scripts": {
    "build": "tsc"
  },
  "dependencies": {
    "monaco-editor": "^0.50.0"
  },
  "devDependencies": {
    "typescript": "^5.5.2"
  }
}

3. Build the Local Package

Ensure your local vim-monaco package is built and the output is in the dist directory.

cd ../vim-monaco
yarn install
yarn build

4. Update the Path in handterm/package.json

Ensure the path in your handterm project's package.json is correct.

{
  "dependencies": {
    "vim-monaco": "file:../vim-monaco"
  }
}

5. Clean and Install Dependencies

Clean the node_modules and reinstall dependencies in your handterm project to ensure it picks up the local package.

cd ../handterm
rm -rf node_modules
yarn install

6. Verify Import in Your Code

Ensure that the import statement in your MonacoEditor.tsx is correct and pointing to the vim-monaco package.

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Import the CSS file

// ... rest of your code

7. Debugging

If you still encounter issues, add some debugging logs to verify if the package is being imported correctly and if the paths are resolved correctly.

Example of Debugging Logs

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Import the CSS file

console.log('monaco:', monaco);
console.log('VimMode:', VimMode);

// ... rest of your code

Vite Configuration

In some cases, you might need to adjust the Vite configuration to ensure it correctly resolves the local package.

Example vite.config.js

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';

export default defineConfig({
  plugins: [react()],
  resolve: {
    alias: {
      'vim-monaco': path.resolve(__dirname, '../vim-monaco/dist/index.js'),
    },
  },
});

Following these steps should help you use your local vim-monaco package in your handterm project. If you still face issues, please ensure the paths are correct and the package structure is valid.

  "module": "dist/vim-monaco.module.js",
  "types": "dist/index.d.ts",
  "files": [
    "dist"
  ],
  "scripts": {
    "build": "tsc && rollup -c"
  },
  "dependencies": {
    "monaco-editor": "^0.50.0"
  },
  "devDependencies": {
    "typescript": "^5.5.2",
    "rollup": "^2.56.3",
    "rollup-plugin-typescript2": "^0.30.0"
  }
}

Step 2: Build the Local Package

Ensure your local vim-monaco package is built correctly.

cd ../vim-monaco
yarn install
yarn build

Step 3: Update handterm/package.json

Ensure the path in your handterm project's package.json is correct.

{
  "dependencies": {
    "vim-monaco": "file:../vim-monaco"
  }
}

Step 4: Clean and Install Dependencies

Clean the node_modules and reinstall dependencies in your handterm project to ensure it picks up the local package.

cd ../handterm
rm -rf node_modules
yarn install

Step 5: Adjust Vite Configuration (if needed)

If you still encounter issues, you might need to adjust the Vite configuration to ensure it correctly resolves the local package.

Example vite.config.ts

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';

export default defineConfig({
  plugins: [react()],
  resolve: {
    alias: {
      'vim-monaco': path.resolve(__dirname, '../vim-monaco/dist/vim-monaco.module.js'),
    },
  },
});

Step 6: Verify Import in Your Code

Ensure that the import statement in your MonacoEditor.tsx is correct and pointing to the vim-monaco package.

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Import the CSS file

// ... rest of your code

Step 7: Debugging

If you still encounter issues, add some debugging logs to verify if the package is being imported correctly and if the paths are resolved correctly.

Example of Debugging Logs

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
