Creating a vim-like experience in a web-based terminal using @xterm/xterm can be quite challenging since vim itself is a highly interactive text editor. However, there are a few approaches you can consider:

Option 1: Integrate a Web-Based Editor

While Firenvim is an interesting project that embeds Neovim in the browser, it might be overkill and complex for your use case. Instead, consider integrating a simpler, more lightweight web-based code editor that can be embedded in your terminal.

Example: Using CodeMirror

CodeMirror is a versatile text editor implemented in JavaScript for the browser. It provides a lot of the features you might be looking for and can be integrated into your @xterm/xterm environment.

Here's a basic example of how you could integrate CodeMirror into your HandTerm component:

  1. Install CodeMirror:

    npm install codemirror
  2. Import and Initialize CodeMirror:

    import React, { useEffect, useRef } from 'react';
    import { Terminal } from '@xterm/xterm';
    import CodeMirror from 'codemirror';
    import 'codemirror/lib/codemirror.css';
    
    const HandTerm = () => {
      const terminalRef = useRef(null);
      const editorRef = useRef(null);
    
      useEffect(() => {
        const term = new Terminal();
        term.open(terminalRef.current);
        term.writeln('Welcome to Handex Term!');
        term.writeln('Login');
        term.write('Username: ');
    
        // Initialize CodeMirror
        const editor = CodeMirror(editorRef.current, {
          lineNumbers: true,
          mode: 'javascript',
        });
    
        // Fetch file content from S3 and set it in the editor
        // Replace this with your actual S3 fetching logic
        const fetchFileContent = async () => {
          const fileContent = await fetchFileFromS3();
          editor.setValue(fileContent);
        };
    
        fetchFileContent();
    
        return () => {
          term.dispose();
        };
      }, []);
    
      return (
        <div className="handterm-container">
          <div ref={terminalRef} />
          <div ref={editorRef} className="editor-container" />
        </div>
      );
    };
    
    export default HandTerm;
    
    // Dummy function to simulate fetching file content from S3
    const fetchFileFromS3 = async () => {
      return 'const example = "Hello, World!";\nconsole.log(example);';
    };

Option 2: Embed Neovim Using Firenvim

If you prefer a real vim experience, Firenvim can be an option. However, it requires embedding Neovim in an iframe or similar structure, which might not be straightforward. You would need to handle various integration issues such as communication between Neovim and your terminal.

Option 3: Implement Custom vim-Like Features

You can also create custom vim-like keybindings and features directly within @xterm/xterm. This approach gives you full control but can be complex to implement.

Conclusion

For simplicity and ease of integration, I recommend starting with CodeMirror. It offers a good balance between functionality and ease of use, and it can be embedded seamlessly into your existing @xterm/xterm setup.

If you need more advanced vim features and are willing to handle the complexities, Firenvim is an option, but it requires more effort to integrate properly.

Sure! I'll convert the previous functional component example to a class component for you. This will involve setting up the terminal and CodeMirror editor in the componentDidMount lifecycle method and cleaning up in componentWillUnmount.

Here is the updated HandTerm class component using CodeMirror:

import React, { Component, createRef } from 'react';
import { Terminal } from '@xterm/xterm';
import CodeMirror from 'codemirror';
import 'codemirror/lib/codemirror.css';

class HandTerm extends Component {
  terminalRef = createRef<HTMLDivElement>();
  editorRef = createRef<HTMLDivElement>();
  terminal: Terminal | null = null;
  editor: CodeMirror.Editor | null = null;

  componentDidMount() {
    // Initialize xterm.js terminal
    this.terminal = new Terminal();
    if (this.terminalRef.current) {
      this.terminal.open(this.terminalRef.current);
      this.terminal.writeln('Welcome to Handex Term!');
      this.terminal.writeln('Login');
      this.terminal.write('Username: ');
    }

    // Initialize CodeMirror
    if (this.editorRef.current) {
      this.editor = CodeMirror(this.editorRef.current, {
        lineNumbers: true,
        mode: 'javascript',
      });

      // Fetch file content from S3 and set it in the editor
      this.fetchFileContent().then((fileContent) => {
        if (this.editor) {
          this.editor.setValue(fileContent);
        }
      });
    }
  }

  componentWillUnmount() {
    // Clean up terminal instance
    if (this.terminal) {
      this.terminal.dispose();
    }
  }

  fetchFileContent = async (): Promise<string> => {
    // Dummy function to simulate fetching file content from S3
    return 'const example = "Hello, World!";\nconsole.log(example);';
  };

  render() {
    return (
      <div className="handterm-container">
        <div ref={this.terminalRef} />
        <div ref={this.editorRef} className="editor-container" />
      </div>
    );
  }
}

export default HandTerm;

Key Points

  1. Initialization:

    • xterm.js terminal is initialized in componentDidMount and attached to the terminalRef.
    • CodeMirror editor is also initialized in componentDidMount and attached to the editorRef.
  2. Cleanup:

    • The terminal instance is disposed of in componentWillUnmount to avoid memory leaks.
  3. Fetching File Content:

    • fetchFileContent is a dummy function simulating fetching content from S3. Replace it with your actual S3 fetching logic.

Styles

Don't forget to add some CSS styles to ensure the terminal and editor containers are displayed correctly. Here's an example:

.handterm-container {
  display: flex;
  flex-direction: column;
  height: 100vh;
}

.editor-container {
  flex: 1;
}

.terminal-container {
  flex: 1;
}

This should give you a starting point to integrate CodeMirror into your HandTerm class component, allowing you to create a vim-like experience in your web-based terminal.

The error indicates that TypeScript cannot find the Editor type in the codemirror package. This might be due to how CodeMirror's types are declared. You can use the CodeMirror.Editor type from codemirror directly.

Here’s the updated code with the correct type import:

  1. Install CodeMirror types:

    npm install @types/codemirror
  2. Update Imports and Component Setup:

    import React, { Component, createRef } from 'react';
    import { Terminal } from '@xterm/xterm';
    import CodeMirror, { EditorFromTextArea } from 'codemirror';
    import 'codemirror/lib/codemirror.css';
    
    class HandTerm extends Component {
      terminalRef = createRef<HTMLDivElement>();
      editorRef = createRef<HTMLDivElement>();
      terminal: Terminal | null = null;
      editor: EditorFromTextArea | null = null;
    
      componentDidMount() {
        // Initialize xterm.js terminal
        this.terminal = new Terminal();
        if (this.terminalRef.current) {
          this.terminal.open(this.terminalRef.current);
          this.terminal.writeln('Welcome to Handex Term!');
          this.terminal.writeln('Login');
          this.terminal.write('Username: ');
        }
    
        // Initialize CodeMirror
        if (this.editorRef.current) {
          this.editor = CodeMirror(this.editorRef.current, {
            lineNumbers: true,
            mode: 'javascript',
          });
    
          // Fetch file content from S3 and set it in the editor
          this.fetchFileContent().then((fileContent) => {
            if (this.editor) {
              this.editor.setValue(fileContent);
            }
          });
        }
      }
    
      componentWillUnmount() {
        // Clean up terminal instance
        if (this.terminal) {
          this.terminal.dispose();
        }
      }
    
      fetchFileContent = async (): Promise<string> => {
        // Dummy function to simulate fetching file content from S3
        return 'const example = "Hello, World!";\nconsole.log(example);';
      };
    
      render() {
        return (
          <div className="handterm-container">
            <div ref={this.terminalRef} />
            <div ref={this.editorRef} className="editor-container" />
          </div>
        );
      }
    }
    
    export default HandTerm;

Key Points

  1. Type Import:

    • The EditorFromTextArea type is imported from codemirror.
  2. Editor Initialization:

    • The editor is initialized using the correct type.

This should resolve the TypeScript error and allow you to proceed with integrating CodeMirror into your HandTerm class component.

Great choice! Using @uiw/react-codemirror simplifies the integration of CodeMirror with React. Let's create a functional component for the CodeMirror editor and then integrate it into your HandTerm class component.

Step 1: Install @uiw/react-codemirror

First, ensure you have the package installed:

yarn add @uiw/react-codemirror

Step 2: Create CodeMirrorEditor.tsx

Here's how you can create the CodeMirrorEditor functional component:

// src/components/CodeMirrorEditor.tsx
import React, { useEffect, useRef } from 'react';
import CodeMirror from '@uiw/react-codemirror';
import 'codemirror/lib/codemirror.css';
import 'codemirror/mode/javascript/javascript'; // Import the desired mode

interface CodeMirrorEditorProps {
  initialValue: string;
  onChange?: (value: string) => void;
}

const CodeMirrorEditor: React.FC<CodeMirrorEditorProps> = ({ initialValue, onChange }) => {
  const editorRef = useRef(null);

  useEffect(() => {
    if (editorRef.current) {
      const editor = editorRef.current.getCodeMirror();
      editor.setValue(initialValue);

      if (onChange) {
        editor.on('change', () => {
          onChange(editor.getValue());
        });
      }
    }
  }, [initialValue, onChange]);

  return (
    <CodeMirror
      ref={editorRef}
      options={{
        mode: 'javascript',
        lineNumbers: true,
      }}
    />
  );
};

export default CodeMirrorEditor;

Step 3: Integrate CodeMirrorEditor into HandTerm

Now, modify the HandTerm class component to use the CodeMirrorEditor component.

// src/components/HandTerm.tsx
import React, { Component, createRef } from 'react';
import { Terminal } from '@xterm/xterm';
import CodeMirrorEditor from './CodeMirrorEditor';
import 'codemirror/lib/codemirror.css';
import 'xterm/css/xterm.css';

class HandTerm extends Component {
  terminalRef = createRef<HTMLDivElement>();
  terminal: Terminal | null = null;

  state = {
    fileContent: '',
  };

  componentDidMount() {
    // Initialize xterm.js terminal
    this.terminal = new Terminal();
    if (this.terminalRef.current) {
      this.terminal.open(this.terminalRef.current);
      this.terminal.writeln('Welcome to Handex Term!');
      this.terminal.writeln('Login');
      this.terminal.write('Username: ');
    }

    // Fetch file content from S3 and set it in the state
    this.fetchFileContent().then((fileContent) => {
      this.setState({ fileContent });
    });
  }

  componentWillUnmount() {
    // Clean up terminal instance
    if (this.terminal) {
      this.terminal.dispose();
    }
  }

  fetchFileContent = async (): Promise<string> => {
    // Dummy function to simulate fetching file content from S3
    return 'const example = "Hello, World!";\nconsole.log(example);';
  };

  handleEditorChange = (value: string) => {
    // Handle changes in the CodeMirror editor
    console.log('Editor content changed:', value);
  };

  render() {
    return (
      <div className="handterm-container">
        <div ref={this.terminalRef} className="terminal-container" />
        <CodeMirrorEditor
          initialValue={this.state.fileContent}
          onChange={this.handleEditorChange}
        />
      </div>
    );
  }
}

export default HandTerm;

Key Points

  1. CodeMirrorEditor Component:

    • A functional component that initializes CodeMirror and sets initial content.
    • Uses useEffect to handle editor setup and change events.
  2. HandTerm Component:

    • Fetches file content and passes it to CodeMirrorEditor via props.
    • Handles changes from the editor using a callback.

Styles

Make sure to add some CSS styles to ensure the terminal and editor containers are displayed correctly:

/* src/components/HandTerm.css */
.handterm-container {
  display: flex;
  flex-direction: column;
  height: 100vh;
}

.terminal-container {
  flex: 1;
}

.editor-container {
  flex: 1;
}

And import the CSS file in HandTerm.tsx:

import './HandTerm.css';

This setup should give you a working integration of @uiw/react-codemirror within your HandTerm class component, providing a vim-like editing experience.

The mode: 'javascript' option in CodeMirror specifies the syntax highlighting mode for JavaScript. It tells CodeMirror to apply JavaScript-specific syntax rules and styling to the text within the editor.

Adding Vim Keybindings

To implement vim keybindings, you'll need to use the keyMap option provided by CodeMirror. CodeMirror includes a Vim key map that you can enable to provide a vim-like experience.

Step-by-Step Implementation

  1. Install CodeMirror KeyMap Vim You need to install the necessary CodeMirror keymap for Vim:

    yarn add codemirror keymap/vim
  2. Update CodeMirrorEditor.tsx to Use Vim Keybindings Modify the CodeMirrorEditor component to include the Vim keybindings:

    // src/components/CodeMirrorEditor.tsx
    import React, { useEffect, useRef } from 'react';
    import CodeMirror from '@uiw/react-codemirror';
    import 'codemirror/lib/codemirror.css';
    import 'codemirror/mode/javascript/javascript'; // Import the desired mode
    import 'codemirror/keymap/vim'; // Import Vim keymap
    
    interface CodeMirrorEditorProps {
      initialValue: string;
      onChange?: (value: string) => void;
    }
    
    const CodeMirrorEditor: React.FC<CodeMirrorEditorProps> = ({ initialValue, onChange }) => {
      const editorRef = useRef(null);
    
      useEffect(() => {
        if (editorRef.current) {
          const editor = editorRef.current.getCodeMirror();
          editor.setValue(initialValue);
    
          if (onChange) {
            editor.on('change', () => {
              onChange(editor.getValue());
            });
          }
        }
      }, [initialValue, onChange]);
    
      return (
        <CodeMirror
          ref={editorRef}
          options={{
            mode: 'javascript',
            lineNumbers: true,
            keyMap: 'vim', // Enable Vim keybindings
          }}
        />
      );
    };
    
    export default CodeMirrorEditor;
  3. Ensure Vim KeyMap is Loaded Correctly To ensure that the Vim keymap is loaded correctly, you might need to import it directly in your project:

    // src/components/CodeMirrorEditor.tsx
    import 'codemirror/keymap/vim';

Full Example

Here’s the complete CodeMirrorEditor.tsx with Vim keybindings:

// src/components/CodeMirrorEditor.tsx
import React, { useEffect, useRef } from 'react';
import CodeMirror from '@uiw/react-codemirror';
import 'codemirror/lib/codemirror.css';
import 'codemirror/mode/javascript/javascript'; // Import the desired mode
import 'codemirror/keymap/vim'; // Import Vim keymap

interface CodeMirrorEditorProps {
  initialValue: string;
  onChange?: (value: string) => void;
}

const CodeMirrorEditor: React.FC<CodeMirrorEditorProps> = ({ initialValue, onChange }) => {
  const editorRef = useRef(null);

  useEffect(() => {
    if (editorRef.current) {
      const editor = editorRef.current.getCodeMirror();
      editor.setValue(initialValue);

      if (onChange) {
        editor.on('change', () => {
          onChange(editor.getValue());
        });
      }
    }
  }, [initialValue, onChange]);

  return (
    <CodeMirror
      ref={editorRef}
      options={{
        mode: 'javascript',
        lineNumbers: true,
        keyMap: 'vim', // Enable Vim keybindings
      }}
    />
  );
};

export default CodeMirrorEditor;

Integrate with HandTerm

Make sure the HandTerm component imports and uses CodeMirrorEditor correctly:

// src/components/HandTerm.tsx
import React, { Component, createRef } from 'react';
import { Terminal } from '@xterm/xterm';
import CodeMirrorEditor from './CodeMirrorEditor';
import 'codemirror/lib/codemirror.css';
import 'xterm/css/xterm.css';
import './HandTerm.css';

class HandTerm extends Component {
  terminalRef = createRef<HTMLDivElement>();
  terminal: Terminal | null = null;

  state = {
    fileContent: '',
  };

  componentDidMount() {
    // Initialize xterm.js terminal
    this.terminal = new Terminal();
    if (this.terminalRef.current) {
      this.terminal.open(this.terminalRef.current);
      this.terminal.writeln('Welcome to Handex Term!');
      this.terminal.writeln('Login');
      this.terminal.write('Username: ');
    }

    // Fetch file content from S3 and set it in the

The error indicates that TypeScript cannot find the `getCodeMirror` method on the `CodeMirror` component ref. This is because the `@uiw/react-codemirror` component doesn't expose such a method directly.

Instead, you should interact with the CodeMirror instance through the `onChange` and `value` props provided by the `@uiw/react-codemirror` component.

Here’s how to update your `CodeMirrorEditor` component to handle this correctly:

### Updated `CodeMirrorEditor.tsx`
```tsx
// src/components/CodeMirrorEditor.tsx
import React from 'react';
import { UnControlled as CodeMirror } from '@uiw/react-codemirror';
import 'codemirror/lib/codemirror.css';
import 'codemirror/mode/javascript/javascript'; // Import the desired mode
import 'codemirror/keymap/vim'; // Import Vim keymap

interface CodeMirrorEditorProps {
  initialValue: string;
  onChange?: (value: string) => void;
}

const CodeMirrorEditor: React.FC<CodeMirrorEditorProps> = ({ initialValue, onChange }) => {
  return (
    <CodeMirror
      value={initialValue}
      options={{
        mode: 'javascript',
        lineNumbers: true,
        keyMap: 'vim', // Enable Vim keybindings
      }}
      onChange={(editor, data, value) => {
        if (onChange) {
          onChange(value);
        }
      }}
    />
  );
};

export default CodeMirrorEditor;

Key Changes

  1. Component Type:

    • Use UnControlled component from @uiw/react-codemirror to manage the editor's content non-controllably.
  2. onChange Prop:

    • The onChange function now directly receives the current value of the editor and passes it to the parent component if provided.

Integration in HandTerm

Here's how to integrate the updated CodeMirrorEditor into the HandTerm component:

// src/components/HandTerm.tsx
import React, { Component, createRef } from 'react';
import { Terminal } from '@xterm/xterm';
import CodeMirrorEditor from './CodeMirrorEditor';
import 'codemirror/lib/codemirror.css';
import 'xterm/css/xterm.css';
import './HandTerm.css';

class HandTerm extends Component {
  terminalRef = createRef<HTMLDivElement>();
  terminal: Terminal | null = null;

  state = {
    fileContent: '',
  };

  componentDidMount() {
    // Initialize xterm.js terminal
    this.terminal = new Terminal();
    if (this.terminalRef.current) {
      this.terminal.open(this.terminalRef.current);
      this.terminal.writeln('Welcome to Handex Term!');
      this.terminal.writeln('Login');
      this.terminal.write('Username: ');
    }

    // Fetch file content from S3 and set it in the state
    this.fetchFileContent().then((fileContent) => {
      this.setState({ fileContent });
    });
  }

  componentWillUnmount() {
    // Clean up terminal instance
    if (this.terminal) {
      this.terminal.dispose();
    }
  }

  fetchFileContent = async (): Promise<string> => {
    // Dummy function to simulate fetching file content from S3
    return 'const example = "Hello, World!";\nconsole.log(example);';
  };

  handleEditorChange = (value: string) => {
    // Handle changes in the CodeMirror editor
    console.log('Editor content changed:', value);
  };

  render() {
    return (
      <div className="handterm-container">
        <div ref={this.terminalRef} className="terminal-container" />
        <CodeMirrorEditor
          initialValue={this.state.fileContent}
          onChange={this.handleEditorChange}
        />
      </div>
    );
  }
}

export default HandTerm;

CSS Styles

Make sure your CSS styles are correctly set up:

/* src/components/HandTerm.css */
.handterm-container {
  display: flex;
  flex-direction: column;
  height: 100vh;
}

.terminal-container {
  flex: 1;
}

.editor-container {
  flex: 1;
}

Summary

This setup should now properly integrate CodeMirror with Vim keybindings into your HandTerm class component. The CodeMirrorEditor component is responsible for rendering the editor and handling changes, while the HandTerm component manages the terminal and editor content state.

The error is occurring because the getCodeMirror method does not exist on the @uiw/react-codemirror component's ref. Instead, you should use the UnControlled component from @uiw/react-codemirror and handle changes through the onChange event.

Here’s how you can update your CodeMirrorEditor component to eliminate the error and properly handle the Vim keymap:

Updated CodeMirrorEditor.tsx

// src/components/CodeMirrorEditor.tsx
import React from 'react';
import { UnControlled as CodeMirror } from '@uiw/react-codemirror';
import 'codemirror/lib/codemirror.css';
import 'codemirror/mode/javascript/javascript'; // Import the desired mode
import '@replit/codemirror-vim'; // Import Vim keymap

interface CodeMirrorEditorProps {
  initialValue: string;
  onChange?: (value: string) => void;
}

const CodeMirrorEditor: React.FC<CodeMirrorEditorProps> = ({ initialValue, onChange }) => {
  return (
    <CodeMirror
      value={initialValue}
      options={{
        mode: 'javascript',
        lineNumbers: true,
        keyMap: 'vim', // Enable Vim keybindings
      }}
      onChange={(editor, data, value) => {
        if (onChange) {
          onChange(value);
        }
      }}
    />
  );

It looks like the UnControlled component might not be exported as a named export from @uiw/react-codemirror. Instead, you might need to import it as the default export or directly use the CodeMirror component.

Let's update the CodeMirrorEditor component to handle this correctly.

Updated CodeMirrorEditor.tsx

For simplicity, we'll use the default export and ensure it works as an uncontrolled component:

// src/components/CodeMirrorEditor.tsx
import React from 'react';
import CodeMirror from '@uiw/react-codemirror';
import 'codemirror/lib/codemirror.css';
import 'codemirror/mode/javascript/javascript'; // Import the desired mode
import '@replit/codemirror-vim'; // Import Vim keymap

interface CodeMirrorEditorProps {
  initialValue: string;
  onChange?: (value: string) => void;
}

const CodeMirrorEditor: React.FC<CodeMirrorEditorProps> = ({ initialValue, onChange }) => {
  return (
    <CodeMirror
      value={initialValue}
      options={{
        mode: 'javascript',
        lineNumbers: true,
        keyMap: 'vim', // Enable Vim keybindings
      }}
      onChange={(editor, data, value) => {
        if (onChange) {
          onChange(value);
        }
      }}
    />
  );
};

export default CodeMirrorEditor;

Key Changes

  1. Default Import:

    • Import CodeMirror as the default export from @uiw/react-codemirror.
  2. Options and Event Handling:

    • Ensure the value prop initializes the editor content.
    • Use the onChange event to handle changes in the editor.

Integration in HandTerm

Here's how to integrate the updated CodeMirrorEditor into the HandTerm component:

// src/components/HandTerm.tsx
import React, { Component, createRef } from 'react';
import { Terminal } from '@xterm/xterm';
import CodeMirrorEditor from './CodeMirrorEditor';
import 'codemirror/lib/codemirror.css';
import 'xterm/css/xterm.css';
import './HandTerm.css';

class HandTerm extends Component {
  terminalRef = createRef<HTMLDivElement>();
  terminal: Terminal | null = null;

  state = {
    fileContent: '',
  };

  componentDidMount() {
    // Initialize xterm.js terminal
    this.terminal = new Terminal();
    if (this.terminalRef.current) {
      this.terminal.open(this.terminalRef.current);
      this.terminal.writeln('Welcome to Handex Term!');
      this.terminal.writeln('Login');
      this.terminal.write('Username: ');
    }

    // Fetch file content from S3 and set it in the state
    this.fetchFileContent().then((fileContent) => {
      this.setState({ fileContent });
    });
  }

  componentWillUnmount() {
    // Clean up terminal instance
    if (this.terminal) {
      this.terminal.dispose();
    }
  }

  fetchFileContent = async (): Promise<string> => {
    // Dummy function to simulate fetching file content from S3
    return 'const example = "Hello, World!";\nconsole.log(example);';
  };

  handleEditorChange = (value: string) => {
    // Handle changes in the CodeMirror editor
    console.log('Editor content changed:', value);
  };

  render() {
    return (
      <div className="handterm-container">
        <div ref={this.terminalRef} className="terminal-container" />
        <CodeMirrorEditor
          initialValue={this.state.fileContent}
          onChange={this.handleEditorChange}
        />
      </div>
    );
  }
}

export default HandTerm;

CSS Styles

Ensure your CSS styles are correctly set up:

/* src/components/HandTerm.css */
.handterm-container {
  display: flex;
  flex-direction: column;
  height: 100vh;
}

.terminal-container {
  flex: 1;
}

.editor-container {
  flex: 1;
}

Summary

This setup should now properly integrate CodeMirror with Vim keybindings into your HandTerm class component. The CodeMirrorEditor component is responsible for rendering the editor and handling changes, while the HandTerm component manages the terminal and editor content state.

The error indicates that the onChange event handler provided by @uiw/react-codemirror expects a different signature than the one used in the code. The correct signature for the onChange event handler should match the one expected by the ReactCodeMirrorProps type.

Let's update the onChange handler to match the expected signature:

Updated CodeMirrorEditor.tsx

// src/components/CodeMirrorEditor.tsx
import React from 'react';
import CodeMirror from '@uiw/react-codemirror';
import 'codemirror/lib/codemirror.css';
import 'codemirror/mode/javascript/javascript'; // Import the desired mode
import '@replit/codemirror-vim'; // Import Vim keymap

interface CodeMirrorEditorProps {
  initialValue: string;
  onChange?: (value: string, viewUpdate: any) => void; // Update the type signature
}

const CodeMirrorEditor: React.FC<CodeMirrorEditorProps> = ({ initialValue, onChange }) => {
  return (
    <CodeMirror
      value={initialValue}
      options={{
        mode: 'javascript',
        lineNumbers: true,
        keyMap: 'vim', // Enable Vim keybindings
      }}
      onChange={(value, viewUpdate) => {
        if (onChange) {
          onChange(value, viewUpdate);
        }
      }}
    />
  );
};

export default CodeMirrorEditor;

Integration in HandTerm

Ensure that the HandTerm component handles the onChange event correctly:

// src/components/HandTerm.tsx
import React, { Component, createRef } from 'react';
import { Terminal } from '@xterm/xterm';
import CodeMirrorEditor from './CodeMirrorEditor';
import 'codemirror/lib/codemirror.css';
import 'xterm/css/xterm.css';
import './HandTerm.css';

class HandTerm extends Component {
  terminalRef = createRef<HTMLDivElement>();
  terminal: Terminal | null = null;

  state = {
    fileContent: '',
  };

  componentDidMount() {
    // Initialize xterm.js terminal
    this.terminal = new Terminal();
    if (this.terminalRef.current) {
      this.terminal.open(this.terminalRef.current);
      this.terminal.writeln('Welcome to Handex Term!');
      this.terminal.writeln('Login');
      this.terminal.write('Username: ');
    }

    // Fetch file content from S3 and set it in the state
    this.fetchFileContent().then((fileContent) => {
      this.setState({ fileContent });
    });
  }

  componentWillUnmount() {
    // Clean up terminal instance
    if (this.terminal) {
      this.terminal.dispose();
    }
  }

  fetchFileContent = async (): Promise<string> => {
    // Dummy function to simulate fetching file content from S3
    return 'const example = "Hello, World!";\nconsole.log(example);';
  };

  handleEditorChange = (value: string, viewUpdate: any) => {
    // Handle changes in the CodeMirror editor
    console.log('Editor content changed:', value);
  };

  render() {
    return (
      <div className="handterm-container">
        <div ref={this.terminalRef} className="terminal-container" />
        <CodeMirrorEditor
          initialValue={this.state.fileContent}
          onChange={this.handleEditorChange}
        />
      </div>
    );
  }
}

export default HandTerm;

Summary

The onChange handler is now updated to match the expected signature, which should resolve the TypeScript error. The CodeMirrorEditor component properly passes the new value and viewUpdate arguments to the onChange handler, and the HandTerm component handles these arguments accordingly.

The error indicates that the options property is not directly accepted by the CodeMirror component from @uiw/react-codemirror. Instead, the options should be passed directly as props to the CodeMirror component.

Let's update the CodeMirrorEditor component to pass these options directly:

Updated CodeMirrorEditor.tsx

// src/components/CodeMirrorEditor.tsx
import React from 'react';
import CodeMirror from '@uiw/react-codemirror';
import 'codemirror/lib/codemirror.css';
import 'codemirror/mode/javascript/javascript'; // Import the desired mode
import '@replit/codemirror-vim'; // Import Vim keymap

interface CodeMirrorEditorProps {
  initialValue: string;
  onChange?: (value: string, viewUpdate: any) => void;
}

const CodeMirrorEditor: React.FC<CodeMirrorEditorProps> = ({ initialValue, onChange }) => {
  return (
    <CodeMirror
      value={initialValue}
      mode="javascript"
      lineNumbers={true}
      keyMap="vim" // Enable Vim keybindings
      onChange={(value, viewUpdate) => {
        if (onChange) {
          onChange(value, viewUpdate);
        }
      }}
    />
  );
};

export default CodeMirrorEditor;

Summary

In this updated version, the mode, lineNumbers, and keyMap options are passed directly as props to the CodeMirror component instead of being grouped under an options object. This should align with the expected props for @uiw/react-codemirror and resolve the TypeScript error.

Integration in HandTerm

Ensure that the HandTerm component imports and uses CodeMirrorEditor correctly:

// src/components/HandTerm.tsx
import React, { Component, createRef } from 'react';
import { Terminal } from '@xterm/xterm';
import CodeMirrorEditor from './CodeMirrorEditor';
import 'codemirror/lib/codemirror.css';
import 'xterm/css/xterm.css';
import './HandTerm.css';

class HandTerm extends Component {
  terminalRef = createRef<HTMLDivElement>();
  terminal: Terminal | null = null;

  state = {
    fileContent: '',
  };

  componentDidMount() {
    // Initialize xterm.js terminal
    this.terminal = new Terminal();
    if (this.terminalRef.current) {
      this.terminal.open(this.terminalRef.current);
      this.terminal.writeln('Welcome to Handex Term!');
      this.terminal.writeln('Login');
      this.terminal.write('Username: ');
    }

    // Fetch file content from S3 and set it in the state
    this.fetchFileContent().then((fileContent) => {
      this.setState({ fileContent });
    });
  }

  componentWillUnmount() {
    // Clean up terminal instance
    if (this.terminal) {
      this.terminal.dispose();
    }
  }

  fetchFileContent = async (): Promise<string> => {
    // Dummy function to simulate fetching file content from S3
    return 'const example = "Hello, World!";\nconsole.log(example);';
  };

  handleEditorChange = (value: string, viewUpdate: any) => {
    // Handle changes in the CodeMirror editor
    console.log('Editor content changed:', value);
  };

  render() {
    return (
      <div className="handterm-container">
        <div ref={this.terminalRef} className="terminal-container" />
        <CodeMirrorEditor
          initialValue={this.state.fileContent}
          onChange={this.handleEditorChange}
        />
      </div>
    );
  }
}

export default HandTerm;

This setup should now properly integrate CodeMirror with Vim keybindings into your HandTerm class component. The CodeMirrorEditor component is responsible for rendering the editor and handling changes, while the HandTerm component manages the terminal and editor content state.

The error indicates that the @uiw/react-codemirror component does not directly accept mode, lineNumbers, and keyMap props. Instead, these should be passed within an options prop.

Let's correct this by passing the configuration options inside the options prop:

Updated CodeMirrorEditor.tsx

// src/components/CodeMirrorEditor.tsx
import React from 'react';
import CodeMirror from '@uiw/react-codemirror';
import 'codemirror/lib/codemirror.css';
import 'codemirror/mode/javascript/javascript'; // Import the desired mode
import '@replit/codemirror-vim'; // Import Vim keymap

interface CodeMirrorEditorProps {
  initialValue: string;
  onChange?: (value: string, viewUpdate: any) => void;
}

const CodeMirrorEditor: React.FC<CodeMirrorEditorProps> = ({ initialValue, onChange }) => {
  return (
    <CodeMirror
      value={initialValue}
      options={{
        mode: 'javascript',
        lineNumbers: true,
        keyMap: 'vim', // Enable Vim keybindings
      }}
      onChange={(editor, data, value) => {
        if (onChange) {
          onChange(value, data);
        }
      }}
    />
  );
};

export default CodeMirrorEditor;

Key Changes

  1. Using options Prop:

    • Pass configuration options (mode, lineNumbers, keyMap) within the options prop.
  2. Event Handler Signature:

    • Adjust the onChange handler signature to match the expected parameters: (editor, data, value).

Integration in HandTerm

Make sure the HandTerm component uses the updated CodeMirrorEditor correctly:

// src/components/HandTerm.tsx
import React, { Component, createRef } from 'react';
import { Terminal } from '@xterm/xterm';
import CodeMirrorEditor from './CodeMirrorEditor';
import 'codemirror/lib/codemirror.css';
import 'xterm/css/xterm.css';
import './HandTerm.css';

class HandTerm extends Component {
  terminalRef = createRef<HTMLDivElement>();
  terminal: Terminal | null = null;

  state = {
    fileContent: '',
  };

  componentDidMount() {
    // Initialize xterm.js terminal
    this.terminal = new Terminal();
    if (this.terminalRef.current) {
      this.terminal.open(this.terminalRef.current);
      this.terminal.writeln('Welcome to Handex Term!');
      this.terminal.writeln('Login');
      this.terminal.write('Username: ');
    }

    // Fetch file content from S3 and set it in the state
    this.fetchFileContent().then((fileContent) => {
      this.setState({ fileContent });
    });
  }

  componentWillUnmount() {
    // Clean up terminal instance
    if (this.terminal) {
      this.terminal.dispose();
    }
  }

  fetchFileContent = async (): Promise<string> => {
    // Dummy function to simulate fetching file content from S3
    return 'const example = "Hello, World!";\nconsole.log(example);';
  };

  handleEditorChange = (value: string, viewUpdate: any) => {
    // Handle changes in the CodeMirror editor
    console.log('Editor content changed:', value);
  };

  render() {
    return (
      <div className="handterm-container">
        <div ref={this.terminalRef} className="terminal-container" />
        <CodeMirrorEditor
          initialValue={this.state.fileContent}
          onChange={this.handleEditorChange}
        />
      </div>
    );
  }
}

export default HandTerm;

Summary

The options prop is used to pass the configuration settings (mode, lineNumbers, keyMap) to the CodeMirror component. This should align with the expected props for @uiw/react-codemirror and resolve the TypeScript error.

The CodeMirrorEditor component is now responsible for rendering the editor with the correct settings and handling changes, while the HandTerm component manages the terminal and editor content state.

It seems that the @uiw/react-codemirror package doesn't accept an options prop directly. Instead, the individual options should be passed as separate props.

Given this, you should pass the mode, lineNumbers, and keyMap directly to the CodeMirror component, not wrapped inside an options object.

Here’s how you can update your CodeMirrorEditor.tsx component:

Updated CodeMirrorEditor.tsx

// src/components/CodeMirrorEditor.tsx
import React from 'react';
import CodeMirror from '@uiw/react-codemirror';
import 'codemirror/lib/codemirror.css';
import 'codemirror/mode/javascript/javascript'; // Import the desired mode
import '@replit/codemirror-vim'; // Import Vim keymap

interface CodeMirrorEditorProps {
  initialValue: string;
  onChange?: (value: string, viewUpdate: any) => void;
}

const CodeMirrorEditor: React.FC<CodeMirrorEditorProps> = ({ initialValue, onChange }) => {
  return (
    <CodeMirror
      value={initialValue}
      mode="javascript"
      lineNumbers={true}
      keyMap="vim" // Enable Vim keybindings
      onChange={(value, viewUpdate) => {
        if (onChange) {
          onChange(value, viewUpdate);
        }
      }}
    />
  );
};

export default CodeMirrorEditor;

Key Changes

  1. Directly Passing Props:
    • Pass mode, lineNumbers, and keyMap directly as props to the CodeMirror component.

Integration in HandTerm

Ensure that the HandTerm component uses the updated CodeMirrorEditor correctly:

// src/components/HandTerm.tsx
import React, { Component, createRef } from 'react';
import { Terminal } from '@xterm/xterm';
import CodeMirrorEditor from './CodeMirrorEditor';
import 'codemirror/lib/codemirror.css';
import 'xterm/css/xterm.css';
import './HandTerm.css';

class HandTerm extends Component {
  terminalRef = createRef<HTMLDivElement>();
  terminal: Terminal | null = null;

  state = {
    fileContent: '',
  };

  componentDidMount() {
    // Initialize xterm.js terminal
    this.terminal = new Terminal();
    if (this.terminalRef.current) {
      this.terminal.open(this.terminalRef.current);
      this.terminal.writeln('Welcome to Handex Term!');
      this.terminal.writeln('Login');
      this.terminal.write('Username: ');
    }

    // Fetch file content from S3 and set it in the state
    this.fetchFileContent().then((fileContent) => {
      this.setState({ fileContent });
    });
  }

  componentWillUnmount() {
    // Clean up terminal instance
    if (this.terminal) {
      this.terminal.dispose();
    }
  }

  fetchFileContent = async (): Promise<string> => {
    // Dummy function to simulate fetching file content from S3
    return 'const example = "Hello, World!";\nconsole.log(example);';
  };

  handleEditorChange = (value: string, viewUpdate: any) => {
    // Handle changes in the CodeMirror editor
    console.log('Editor content changed:', value);
  };

  render() {
    return (
      <div className="handterm-container">
        <div ref={this.terminalRef} className="terminal-container" />
        <CodeMirrorEditor
          initialValue={this.state.fileContent}
          onChange={this.handleEditorChange}
        />
      </div>
    );
  }
}

export default HandTerm;

Summary

By passing the mode, lineNumbers, and keyMap directly as props to the CodeMirror component, we align with the expected interface for @uiw/react-codemirror. This should resolve the TypeScript error and ensure that the component is configured correctly.
