It seems like the issue is with the timing of when monaco is attached to the window and when it is being accessed in adapter.ts. To ensure monaco is available globally before it is used in adapter.ts, you can use the monacoReady promise.

Step-by-Step Solution

  1. Ensure monacoReady is Resolved Before Usage: In your adapter.ts file, wait for the monacoReady promise to resolve before accessing window.monaco.

  2. Update Your adapter.ts: Modify your adapter.ts to wait for the monacoReady promise to resolve before accessing window.monaco.

// src/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";

console.log('CodeMirror adapter loaded', window);

declare global {
  interface Window {
    monaco: typeof monaco;
    monacoReady: Promise<void>;
  }
}

window.monacoReady.then(() => {
  const SelectionDirection = window.monaco.SelectionDirection;
  console.log('SelectionDirection:', SelectionDirection);

  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;
    }
  }

  // Export the class after monaco is ready
  (window as any).CmSelection = CmSelection;
}).catch(error => {
  console.error('Error waiting for monaco:', error);
});

Improve Source Maps for Debugging

To improve source maps and make debugging easier in VS Code, ensure the following:

  1. Enable Source Maps in Your Build Configuration: Ensure that your build tool (e.g., Vite, Webpack) is configured to generate source maps.

  2. Update vite.config.ts (if using Vite): Ensure source maps are enabled in Vite by adding the following configuration:

// vite.config.ts
import { defineConfig } from 'vite';

export default defineConfig({
  build: {
    sourcemap: true,
  },
});
  1. Link Local Package with Source Maps: When linking a local package, ensure that source maps are included in the build output of the package.

  2. Debugging in VS Code:

    • Open the Run and Debug tab in VS Code.
    • Configure your launch configuration (launch.json) to attach to the browser and enable source maps.

Example launch.json configuration for Chrome:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Launch Chrome against localhost",
      "type": "chrome",
      "request": "launch",
      "url": "http://localhost:5173",
      "webRoot": "${workspaceFolder}",
      "sourceMaps": true,
      "sourceMapPathOverrides": {
        "webpack:///src/*": "${webRoot}/src/*"
      }
    }
  ]
}

By following these steps, you can ensure that monaco is available globally before it is used in adapter.ts and improve the debugging experience by generating and using source maps.

To ensure SelectionDirection is available globally in adapter.ts, you can declare it as a let variable at the top of the file and then set its value within the window.monacoReady.then() block. This way, SelectionDirection will be accessible throughout the file.

Updated adapter.ts Example

// src/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";

console.log('CodeMirror adapter loaded', window);

declare global {
  interface Window {
    monaco: typeof monaco;
    monacoReady: Promise<void>;
  }
}

// Declare SelectionDirection globally
let SelectionDirection: any;

window.monacoReady.then(() => {
  SelectionDirection = window.monaco.SelectionDirection;
  console.log('SelectionDirection:', SelectionDirection);

  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;
    }
  }

  // Export the class after monaco is ready
  (window as any).CmSelection = CmSelection;
}).catch(error => {
  console.error('Error waiting for monaco:', error);
});

// Example usage in a class
class EditorAdapter {
  getAnchorForSelection(sel: ISelection) {
    const selection = liftSelection(sel);
    if (selection.isEmpty()) {
      return selection.getPosition();
    }

    return selection.getDirection() === SelectionDirection.LTR
      ? selection.getStartPosition()
      : selection.getEndPosition();
  }
}

Updated launch.json for Better Debugging

Your launch.json is mostly fine, but you might want to add specific configurations for easier debugging. Here's an updated version:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "chrome",
      "request": "launch",
      "name": "Launch Chrome against localhost",
      "url": "http://localhost:5173",
      "webRoot": "${workspaceFolder}",
      "sourceMaps": true,
      "resolveSourceMapLocations": [
        "${workspaceFolder}/**",
        "!**/node_modules/**"
      ],
      "sourceMapPathOverrides": {
        "webpack:///./*": "${webRoot}/*",
        "webpack:///*": "*",
        "webpack:///src/*": "${webRoot}/src/*"
      }
    },
    {
      "type": "android-webview",
      "request": "attach",
      "name": "Attach to Android WebView",
      "application": "com.android.chrome",
      "webRoot": "${workspaceFolder}"
    },
    {
      "type": "msedge",
      "request": "launch",
      "name": "Launch Edge",
      "runtimeArgs": [
        "--preserve-symlinks"
      ],
      "url": "http://localhost:5173",
      "webRoot": "${workspaceFolder}",
      "sourceMaps": true,
      "resolveSourceMapLocations": [
        "${workspaceFolder}/**",
        "!**/node_modules/**"
      ]
    }
  ]
}

Summary

By declaring SelectionDirection as a let variable and setting its value within the window.monacoReady.then(), it will be available throughout the adapter.ts file. Additionally, updating your launch.json with the proper configurations will help you better debug your application in VS Code.

You are correct; you can combine the configurations and add the --preserve-symlinks flag to ensure that your linked vim-monaco library is correctly resolved.

Here is the combined and updated launch.json configuration for both Chrome and Edge:

Combined launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "chrome",
      "request": "launch",
      "name": "Launch Chrome against localhost",
      "url": "http://localhost:5173",
      "webRoot": "${workspaceFolder}",
      "sourceMaps": true,
      "resolveSourceMapLocations": [
        "${workspaceFolder}/**",
        "!**/node_modules/**"
      ],
      "sourceMapPathOverrides": {
        "webpack:///./*": "${webRoot}/*",
        "webpack:///*": "*",
        "webpack:///src/*": "${webRoot}/src/*"
      },
      "runtimeArgs": [
        "--preserve-symlinks"
      ]
    },
    {
      "type": "msedge",
      "request": "launch",
      "name": "Launch Edge",
      "url": "http://localhost:5173",
      "webRoot": "${workspaceFolder}",
      "sourceMaps": true,
      "resolveSourceMapLocations": [
        "${workspaceFolder}/**",
        "!**/node_modules/**"
      ],
      "sourceMapPathOverrides": {
        "webpack:///./*": "${webRoot}/*",
        "webpack:///*": "*",
        "webpack:///src/*": "${webRoot}/src/*"
      },
      "runtimeArgs": [
        "--preserve-symlinks"
      ]
    },
    {
      "type": "android-webview",
      "request": "attach",
      "name": "Attach to Android WebView",
      "application": "com.android.chrome",
      "webRoot": "${workspaceFolder}"
    }
  ]
}

Explanation:

  1. Combined Configurations: Both Chrome and Edge configurations are included, allowing you to choose which browser to launch for debugging.
  2. --preserve-symlinks: Added to both Chrome and Edge configurations to ensure that the linked vim-monaco library is correctly resolved.
  3. Source Maps and Path Overrides: Configured to ensure that source maps are correctly resolved and debugging works seamlessly.

Now, you can choose to debug your application in either Chrome or Edge by selecting the appropriate configuration in the VS Code Debug panel. This setup should enable you to debug the linked vim-monaco library effectively.

Thank you for the detailed explanation. Let's focus on ensuring monaco is attached to the window object correctly before any code in adapter.ts tries to access it.

Diagnosis

  1. monaco is expected to be attached to the window object in MonacoEditor.tsx.
  2. The error indicates that window.monacoReady is not defined when accessed in adapter.ts.
  3. Ensuring monaco and monacoReady are properly attached to the window object early enough should resolve these issues.

Solution

Let's ensure monaco and monacoReady are attached to the window object in a reliable manner, and then verify that adapter.ts accesses them correctly.

Step-by-Step Solution

  1. Ensure monaco and monacoReady are attached to the window object in MonacoEditor.tsx:

Update MonacoEditor.tsx

// src/components/MonacoEditor.tsx
import { useEffect, useRef } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Ensure this file exists and has the required styles

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  height?: string;
}

// Ensure monacoReady is defined on the window object
if (!window.monacoReady) {
  window.monacoReady = new Promise<void>((resolve) => {
    window.monacoReadyResolve = resolve;
  });
}

declare global {
  interface Window {
    monaco: typeof monaco;
    monacoReady: Promise<void>;
    monacoReadyResolve: () => void;
  }
}

const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

  useEffect(() => {
    if (editorRef.current) {
      // Ensure monaco is available globally
      window.monaco = monaco;
      window.monacoReadyResolve();
      console.log('window.monaco', window.monaco);

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

      editorInstanceRef.current = editor;

      console.log('Monaco Editor created:', editor);

      // Ensure VimMode is loaded after editor creation
      try {
        const vimMode = new VimMode(editor);
        console.log('VimMode created:', vimMode);
      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

      return () => {
        if (editorInstanceRef.current) {
          editorInstanceRef.current.dispose();
        }
      };
    }
  }, [initialValue, language]);

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

export default MonacoEditor;
  1. Ensure adapter.ts waits for monacoReady:

Update adapter.ts

// src/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";

console.log('CodeMirror adapter loaded', window);

declare global {
  interface Window {
    monaco: typeof monaco;
    monacoReady: Promise<void>;
  }
}

// Declare SelectionDirection globally
let SelectionDirection: any;

window.monacoReady.then(() => {
  SelectionDirection = window.monaco.SelectionDirection;
  console.log('SelectionDirection:', SelectionDirection);

  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;
    }
  }

  // Export the class after monaco is ready
  (window as any).CmSelection = CmSelection;
}).catch(error => {
  console.error('Error waiting for monaco:', error);
});

// Example usage in a class
class EditorAdapter {
  getAnchorForSelection(sel: ISelection

Thank you for the detailed explanation. It seems that the issue is indeed related to the order in which the code is executed and how the `monaco` object is being attached to the `window`. Let's address this by ensuring that the `monaco` object is properly attached to the `window` before any other code tries to access it.

### Solution Outline

1. **Ensure `monaco` is attached to the `window` object as early as possible**.
2. **Use a more reliable method to initialize `VimMode` only after `monaco` is available**.

### Step-by-Step Solution

1. **Initialize and Attach `monaco` to the `window` Object**:
   Move the initialization code for `monaco` outside of the `useEffect` to ensure it's executed as early as possible.

### Updated `MonacoEditor.tsx`

```tsx
// src/components/MonacoEditor.tsx
import { useEffect, useRef } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Ensure this file exists and has the required styles

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  height?: string;

It sounds like the issue is indeed related to the timing and order of execution. `new VimMode(editor)` seems to be invoked before `monaco` is even attached to the `window` object, which is causing the error.

Given that `VimMode` initialization depends on `monaco` being available, we need to ensure that `monaco` is attached to the `window` object before `VimMode` is ever created.

### Investigating the Timing Issue

1. **Ensure `monaco` is attached to the `window` as early as possible** but not from within the component lifecycle.
2. **Delay the initialization of `VimMode` until `monaco` is confirmed to exist**.

### Solution

1. **Move `monaco` Attachment Outside the Component**:
   We need to attach `monaco` to the `window` object even before the React component is rendered.

### Update `globalSetup.ts` (or similar)

Create a setup file to ensure `monaco` is attached to the `window` before anything else.

```typescript
// src/globalSetup.ts
import * as monaco from 'monaco-editor';

declare global {
  interface Window {
    monaco: typeof monaco;
    monacoReady: Promise<void>;
    monacoReadyResolve: () => void;
  }
}

// Ensure monacoReady is defined on the window object
if (!window.monacoReady) {
  window.monacoReady = new Promise<void>((resolve) => {
    window.monacoReadyResolve = resolve;
  });
}

// Attach monaco to the window object as early as possible
window.monaco = monaco;
window.monacoReadyResolve();

Import this setup file at the very beginning of your main entry file.

Update main.tsx

// src/main.tsx
import './globalSetup';
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);
  1. Ensure VimMode Initialization Waits for monaco:

Update MonacoEditor.tsx

// src/components/MonacoEditor.tsx
import { useEffect, useRef } from 'react';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css';
import * as monaco from 'monaco-editor'; // Import monaco locally as well

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  height?: string;
}

const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

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

        editorInstanceRef.current = editor;

        console.log('Monaco Editor created:', editor);

        // Ensure VimMode is loaded after editor creation
        try {
          const vimMode = new VimMode(editor);
          console.log('VimMode created:', vimMode);
        } catch (error) {
          console.error('Error initializing VimMode:', error);
        }

        return () => {
          if (editorInstanceRef.current) {
            editorInstanceRef.current.dispose();
          }
        };
      });
    }
  }, [initialValue, language]);

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

export default MonacoEditor;

Summary

By moving the monaco attachment code to a separate setup file (globalSetup.ts) and ensuring it runs before the React application initializes, we can guarantee that monaco is available globally before any component tries to use it. This should prevent the timing issues and ensure VimMode is initialized correctly.

Absolutely, if you need to use forwardRef for your MonacoEditor component to expose certain methods or properties to parent components, we should keep that in place.

Let's combine the changes to ensure monaco is attached to the window early and maintain the forwardRef functionality.

Updated globalSetup.ts

First, ensure monaco is attached to the window object as early as possible.

// src/globalSetup.ts
import * as monaco from 'monaco-editor';

declare global {
  interface Window {
    monaco: typeof monaco;
    monacoReady: Promise<void>;
    monacoReadyResolve: () => void;
  }
}

// Ensure monacoReady is defined on the window object
if (!window.monacoReady) {
  window.monacoReady = new Promise<void>((resolve) => {
    window.monacoReadyResolve = resolve;
  });
}

// Attach monaco to the window object as early as possible
window.monaco = monaco;
window.monacoReadyResolve();

Import this setup file at the very beginning of your main entry file.

Update main.tsx

// src/main.tsx
import './globalSetup';
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

Update MonacoEditor.tsx

Now, update your MonacoEditor component to use forwardRef and ensure monacoReady is awaited before initializing VimMode.

// 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'; // Ensure this file exists and has the required styles

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 editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

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

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

        editorInstanceRef.current = editor;

        console.log('Monaco Editor created:', editor);

        // Ensure VimMode is loaded after editor creation
        try {
          const vimMode = new VimMode(editor);
          vimModeRef.current = vimMode;
          console.log('VimMode created:', vimMode);
        } catch (error) {
          console.error('Error initializing VimMode:', error);
        }

        return () => {
          if (editorInstanceRef.current) {
            editorInstanceRef.current.dispose();
          }
        };
      });
    }
  }, [initialValue, language]);

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

export default MonacoEditor;

Summary

By moving the monaco attachment code to a separate setup file (globalSetup.ts) and ensuring it runs before the React application initializes, we can guarantee that monaco is available globally before any component tries to use it. This also keeps the forwardRef functionality in place for the MonacoEditor component. This approach ensures that VimMode is initialized correctly once monaco is ready.

Great to hear that globalSetup.ts helped fix the initial problem. If monacoReady is no longer required because monaco is guaranteed to be available, you can safely remove it. Let's focus on ensuring the Vim functionality and the status bar work correctly.

Updated MonacoEditor.tsx

Let's first ensure that the Vim functionality is initialized correctly and then add the status bar.

// 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'; // Ensure this file exists and has the required styles

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 editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

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

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

      editorInstanceRef.current = editor;

      console.log('Monaco Editor created:', editor);

      // Ensure VimMode is loaded after editor creation
      try {
        const statusBarContainer = document.getElementById('status');
        if (statusBarContainer) {
          const vimMode = new VimMode(editor, statusBarContainer);
          vimModeRef.current = vimMode;
          console.log('VimMode created:', vimMode);
        } else {
          console.error('Status bar container not found');
        }
      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

      // Handle editor content change
      editor.onDidChangeModelContent(() => {
        if (onChange) {
          onChange(editor.getValue());
        }
      });

      return () => {
        if (editorInstanceRef.current) {
          editorInstanceRef.current.dispose();
        }
      };
    }
  }, [initialValue, language]);

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

export default MonacoEditor;

Summary of Changes

  1. Removed monacoReady: Since monaco is now guaranteed to be available due to globalSetup.ts, it's no longer needed.
  2. Initialized VimMode with Status Bar: Added the status bar element to the VimMode initialization to ensure the Vim status bar works correctly.
  3. Handling Editor Content Change: Added a callback for onDidChangeModelContent to propagate changes if needed.

Ensure vim-monaco is Properly Configured

To confirm Vim functionality, ensure that:

  • The vim-monaco package is correctly installed and linked.
  • The MonacoEditor.css has the appropriate styles for both the editor and the status bar.

Example MonacoEditor.css

Make sure your MonacoEditor.css includes styles for the editor container and the status bar.

.monaco-editor-container {
  position: relative;
  width: 100%;
}

.vim-status-bar {
  position: absolute;
  bottom: 0;
  width: 100%;
  background: #2c2c2c;
  color: #ffffff;
  padding: 5px;
  font-family: monospace;
}

By ensuring these configurations, you should be able to see the Vim functionality in action along with the status bar.

You’re correct; in a React component, it’s generally best to avoid using document.getElementById() and instead use React refs to access DOM elements. This keeps the component more in line with React's declarative and functional paradigms.

Updated MonacoEditor.tsx

We'll use useRef to create a reference for the status bar and pass that to the VimMode initialization.

// 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'; // Ensure this file exists and has the required styles

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 editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);
  const statusBarRef = useRef<HTMLDivElement>(null);

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

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

      editorInstanceRef.current = editor;

      console.log('Monaco Editor created:', editor);

      // Ensure VimMode is loaded after editor creation
      try {
        if (statusBarRef.current) {
          const vimMode = new VimMode(editor, statusBarRef.current);
          vimModeRef.current = vimMode;
          console.log('VimMode created:', vimMode);
        } else {
          console.error('Status bar container not found');
        }
      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

      // Handle editor content change
      editor.onDidChangeModelContent(() => {
        if (onChange) {
          onChange(editor.getValue());
        }
      });

      return () => {
        if (editorInstanceRef.current) {
          editorInstanceRef.current.dispose();
        }
      };
    }
  }, [initialValue, language]);

  return (
    <div>
      <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
      <div ref={statusBarRef} id="status" className="vim-status-bar"></div>
    </div>
  );
});

export default MonacoEditor;

Summary of Changes

  1. Used useRef for Status Bar: Created a ref (statusBarRef) for the status bar and passed it to VimMode initialization.
  2. Ensured React Paradigm: Avoided using document.getElementById() and maintained the React paradigm by using refs.

Ensure vim-monaco is Properly Configured

To confirm Vim functionality, ensure that:

  • The vim-monaco package is correctly installed and linked.
  • The MonacoEditor.css has the appropriate styles for both the editor and the status bar.

Example MonacoEditor.css

Make sure your MonacoEditor.css includes styles for the editor container and the status bar.

.monaco-editor-container {
  position: relative;
  width: 100%;
}

.vim-status-bar {
  position: absolute;
  bottom: 0;
  width: 100%;
  background: #2c2c2c;
  color: #ffffff;
  padding: 5px;
  font-family: monospace;
}

By following these updates, you should have the Vim functionality working correctly along with the status bar in a React-friendly way.

If you have the whole vim-monaco repository and it includes TypeScript definitions, you should be able to refer to the output type definitions directly. Typically, these type definitions are either included in the package itself or generated during the build process.

Steps to Ensure Type Definitions are Available

  1. Check for Type Definitions in vim-monaco: Ensure that vim-monaco has a d.ts file or generates one during the build process.

  2. Reference the Type Definitions in Your Project: Make sure your project can see the type definitions provided by vim-monaco.

Step 1: Check for Type Definitions in vim-monaco

Check if vim-monaco has a types field in its package.json pointing to a .d.ts file.

{
  "name": "vim-monaco",
  "version": "1.0.0",
  "main": "dist/index.js",
  "types": "dist/index.d.ts" // Ensure this is present
}

If it doesn't, you might need to generate the type definitions manually.

Step 2: Generate Type Definitions (If Not Present)

If vim-monaco does not have type definitions, you can generate them using TypeScript.

  1. Add TypeScript Configuration (if not already present):
// tsconfig.json
{
  "compilerOptions": {
    "declaration": true,
    "emitDeclarationOnly": true,
    "outDir": "dist",
    "target": "ES6",
    "module": "commonjs",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true
  },
  "include": ["src"]
}
  1. Run TypeScript Compiler:
tsc

This should generate the .d.ts files in the dist directory.

Step 3: Reference the Type Definitions in Your Project

Ensure your project can see the type definitions provided by vim-monaco.

  1. Install vim-monaco:
yarn add vim-monaco
  1. Import and Use the Types:

If the type definitions are correctly included in vim-monaco, you can import and use them directly.

Example Usage in Your Project

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

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 editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);
  const statusBarRef = useRef<HTMLDivElement>(null);

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

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

      editorInstanceRef.current = editor;

      console.log('Monaco Editor created:', editor);

      // Ensure VimMode is loaded after editor creation
      try {
        if (statusBarRef.current) {
          const statusBar: IStatusBar = { // Example status bar object, customize as needed
            // Add required properties/methods for IStatusBar
          };

          const vimMode = new VimMode(editor, statusBar);
          vimModeRef.current = vimMode;
          console.log('VimMode created:', vimMode);
        } else {
          console.error('Status bar container not found');
        }
      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

      // Handle editor content change
      editor.onDidChangeModelContent(() => {
        if (onChange) {
          onChange(editor.getValue());
        }
      });

      return () => {
        if (editorInstanceRef.current) {
          editorInstanceRef.current.dispose();

The error you're seeing suggests that `monaco.KeyCode` is undefined when `adapter.ts` tries to access it. This is likely because `monaco` is not fully initialized or not correctly referenced when `VimMode` is being created.

Let's ensure that `monaco` and `VimMode` are correctly initialized and that the status bar is correctly set up. Here’s a step-by-step guide to achieve this:

### Step-by-Step Solution

1. **Ensure `monaco` is correctly referenced**.
2. **Initialize `VimMode` with a proper status bar**.
3. **Verify that `monaco` is fully initialized before creating `VimMode`**.

### Updated `MonacoEditor.tsx`

Let's ensure the initialization flow is correct and use React refs to manage the editor and status bar.

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

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 editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<VimMode | null>(null);
    const statusBarRef = useRef<HTMLDivElement>(null);

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

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

        editorInstanceRef.current = editor;

        console.log('Monaco Editor created:', editor);

        // Ensure VimMode is loaded after editor creation
        try {
          if (statusBarRef.current) {
            const statusBar: IStatusBar = {
              setText: (text: string) => {
                if (statusBarRef.current) {
                  statusBarRef.current.textContent = text;
                }
              },
              setError: (text: string) => {
                if (statusBarRef.current) {
                  statusBarRef.current.textContent = text;
                  statusBarRef.current.style.color = 'red';
                }
              },
              setCursor: (text: string) => {
                if (statusBarRef.current) {
                  statusBarRef.current.textContent = text;
                }
              },
              clear: () => {
                if (statusBarRef.current) {
                  statusBarRef.current.textContent = '';
                  statusBarRef.current.style.color = 'inherit';
                }
              },
            };

            const vimMode = new VimMode(editor, statusBar);
            vimModeRef.current = vimMode;
            console.log('VimMode created:', vimMode);
          } else {
            console.error('Status bar container not found');
          }
        } catch (error) {
          console.error('Error initializing VimMode:', error);
        }

        // Handle editor content change
        editor.onDidChangeModelContent(() => {
          if (onChange) {
            onChange(editor.getValue());
          }
        });

        return () => {
          if (editorInstanceRef.current) {
            editorInstanceRef.current.dispose();
          }
        };
      }
    }, [initialValue, language]);

    return (
      <div>
        <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
        <div ref={statusBarRef} id="status" className="vim-status-bar"></div>
      </div>
    );
  }
);

export default MonacoEditor;

Ensure CSS for Status Bar

Make sure your MonacoEditor.css includes styles for the status bar.

.monaco-editor-container {
  position: relative;
  width: 100%;
  height: 100%; /* Ensure it takes full height */
}

.vim-status-bar {
  position: absolute;
  bottom: 0;
  width: 100%;
  background: #2c2c2c;
  color: #ffffff;
  padding: 5px;
  font-family: monospace;
  box

The error you're seeing suggests that TypeScript is unable to resolve the type definitions for the `vim-monaco` package due to the way its `package.json` is configured. This can happen when the `exports` field in `package.json` is not correctly pointing to the type definitions.

### Solution

1. **Verify `package.json` of `vim-monaco`**:
   Ensure that the `package.json` of `vim-monaco` correctly points to the type definitions.

### Check and Update `vim-monaco/package.json`

Ensure that the `package.json` of `vim-monaco` includes the `types` field and that it correctly points to the type definitions file.

```json
{
  "name": "vim-monaco",
  "version": "1.0.0",
  "main": "dist/index.js",
  "types": "dist/index.d.ts", // Ensure this is correct
  "exports": {
    ".": {
      "import": "./dist/vim-monaco.modern.js",
      "require": "./dist/vim-monaco.js",
      "types": "./dist/index.d.ts" // Ensure this is correct
    }
  }
}

Step-by-Step Fix

  1. Update package.json in vim-monaco: Ensure the exports field correctly points to the type definitions.

  2. Rebuild vim-monaco: After updating the package.json, rebuild the vim-monaco package to ensure the changes take effect.

  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 editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<VimMode | null>(null);
    const statusBarRef = useRef<HTMLDivElement>(null);

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

The error you're seeing suggests that there is a missing module or type declaration for `./global` in your `vim-monaco` project. This is causing the TypeScript compiler to fail during the build process.

### Steps to Resolve the Issue

1. **Check for the Missing Module or Type Declarations**:
   Ensure that the `./global` module or its corresponding type declarations are present in the `vim-monaco` project.

2. **Add Missing Type Declarations**:
   If the `./global` module is missing type declarations, you can add a TypeScript declaration file for it.

### Step-by-Step Solution

1. **Check for the Missing Module or Type Declarations**

Inspect the `src/keymap_vim.ts` file around line 65 to see how the `./global` module is being imported.

```typescript
// src/keymap_vim.ts
import { someFunction } from './global'; // Ensure this module exists
  1. Add Missing Type Declarations

If the ./global module is missing or lacks type declarations, you can create a declaration file for it.

Example Declaration File

If ./global is a JavaScript file, you can create a corresponding TypeScript declaration file.

// src/global.d.ts
declare module './global' {
  export function someFunction(): void; // Example function, update as needed
}

Verify the Module Exists

Ensure the ./global module exists in your project.

// src/global.ts
export function someFunction(): void {
  console.log('Function from global module');
}

Update tsconfig.json

Ensure your tsconfig.json includes the src directory.

// tsconfig.json
{
  "compilerOptions": {
    "declaration": true,
    "emitDeclarationOnly": true,
    "outDir": "dist",
    "target": "ES6",
    "module": "commonjs",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true
  },
  "include": ["src"]
}

Rebuild vim-monaco

After adding the missing type declarations, rebuild the vim-monaco project.

cd path/to/vim-monaco
yarn build

Summary

By ensuring the ./global module exists and has corresponding type declarations, you should be able to resolve the TypeScript error and successfully build the vim-monaco project. Once the build is successful, you can update your project to use the updated vim-monaco package.

If your code is importing vimGlobalState from ./global but the ./global module doesn't exist, you'll need to either locate the correct module or create it if it's missing. Since vimGlobalState is used in multiple places, it's likely an important part of your application.

Step-by-Step Solution

  1. Search for vimGlobalState Definition: Look for where vimGlobalState is defined in your project. If it's not found, you might need to create it based on its usage.

  2. Create the Missing ./global Module: If you can't find vimGlobalState, create a new module and define it there.

Step 1: Search for vimGlobalState Definition

Search your entire codebase for the vimGlobalState definition. It should look something like this:

// src/global.ts (This is an example; adjust based on your actual implementation)
export const vimGlobalState = {
  // Define the state properties and methods here
};

Step 2: Create the Missing ./global Module

If you can't find vimGlobalState, create a new module named global.ts and define it there. Here's an example based on typical usage patterns:

// src/global.ts
export const vimGlobalState = {
  // Example properties; replace with actual implementation
  mode: 'normal', // or 'insert', 'visual', etc.
  registers: {},
  marks: {},
  macros: {},
  // Add more properties and methods as needed
};

export function resetVimGlobalState() {
  // Reset the global state to its initial values
  vimGlobalState.mode = 'normal';
  vimGlobalState.registers = {};
  vimGlobalState.marks = {};
  vimGlobalState.macros = {};
  // Reset other properties as needed
}

Update Imports

Ensure all your imports point to the newly created global.ts module:

import { vimGlobalState, resetVimGlobalState } from './global';

Verify and Rebuild

After creating the global.ts module, verify that the TypeScript compiler is happy with the changes and then rebuild the vim-monaco project.

cd path/to/vim-monaco
yarn build

Example global.ts

Here's a more complete example of what global.ts might look like:

// src/global.ts
interface Register {
  content: string;
  // Add more properties as needed
}

interface Macro {
  steps: string[];
  // Add more properties as needed
}

interface VimGlobalState {
  mode: 'normal' | 'insert' | 'visual';
  registers: { [key: string]: Register };
  marks: { [key: string]: any }; // Define the type for marks
  macros: { [key: string]: Macro };
  // Add more properties and methods as needed
}

export const vimGlobalState: VimGlobalState = {
  mode: 'normal',
  registers: {},
  marks: {},
  macros: {},
};

export function resetVimGlobalState() {
  vimGlobalState.mode = 'normal';
  vimGlobalState.registers = {};
  vimGlobalState.marks = {};
  vimGlobalState.macros = {};
  // Reset other properties as needed
}

By creating the global.ts module and defining vimGlobalState and any necessary methods, you should be able to resolve the import errors and successfully build the vim-monaco project. Once the build is successful, you can update your project to use the updated vim-monaco package.

It seems like you're encountering an issue where a property SelectionDirection is being accessed on an undefined object. This error suggests that SelectionDirection is not being properly defined or initialized before it's accessed.

Given the context you've provided, it looks like this error is originating from an adapter module, likely interacting with the Monaco Editor's selection API. Let's ensure proper initialization and add necessary null checks to avoid this issue.

Step-by-Step Solution

  1. Ensure Proper Initialization: Make sure the editor and its selection API are fully initialized before accessing SelectionDirection.

  2. Add Null Checks: Add null checks to safely handle cases where the selection or its properties might be undefined.

Example Code with Null Checks

Here's an updated example of how you might add these checks in your adapter.ts file.

// src/adapter.ts
import * as monaco from 'monaco-editor';

function handleSelection(editor: monaco.editor.IStandaloneCodeEditor) {
  const selection = editor.getSelection();
  if (selection && (selection as any).SelectionDirection) {
    const selectionDirection = (selection as any).SelectionDirection;
    // Proceed with your logic...
  } else {
    console.error('Selection or SelectionDirection is undefined');
  }
}

Ensure Proper Initialization in MonacoEditor.tsx

Ensure that the Monaco Editor is fully initialized before performing operations that rely on its selection API. Here’s an example of how you might ensure this in your MonacoEditor.tsx component:

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

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 editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<VimMode | null>(null);
    const statusBarRef = useRef<HTMLDivElement>(null);

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

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

        editorInstanceRef.current = editor;

        console.log('Monaco Editor created:', editor);

        // Ensure VimMode is loaded after editor creation
        try {
          if (statusBarRef.current) {
            const statusBar: IStatusBar = {
              setText: (text: string) => {
                if (statusBarRef.current) {
                  statusBarRef.current.textContent = text;
                }
              },
              setError: (text: string) => {
                if (statusBarRef.current) {
