To integrate vim keybindings using @replit/codemirror-vim with your CodeMirror setup in a React functional component, you can use the codemirror package directly and set up the editor with the necessary extensions.

Here's how you can create a CodeMirrorEditor component using codemirror and @replit/codemirror-vim:

  1. Install the necessary packages:

    yarn add codemirror @replit/codemirror-vim @codemirror/view

  2. Create the CodeMirrorEditor component:

    // src/components/CodeMirrorEditor.tsx
import React, { useEffect, useRef } from 'react';
import { EditorView, basicSetup } from 'codemirror';
import { vim } from '@replit/codemirror-vim';
import { javascript } from '@codemirror/lang-javascript';

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

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

  useEffect(() => {
    if (editorRef.current) {
      const view = new EditorView({
        doc: initialValue,
        extensions: [
          vim(), // Enable Vim keybindings
          basicSetup,
          javascript(),
          EditorView.updateListener.of((update) => {
            if (update.docChanged && onChange) {
              onChange(view.state.doc.toString());
            }
          }),
        ],
        parent: editorRef.current,
      });

      return () => view.destroy();
    }
  }, [initialValue, onChange]);

  return <div ref={editorRef} />;
};

export default CodeMirrorEditor;

  3. Integrate the CodeMirrorEditor into your TUI component:

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

const HandTerm: React.FC = () => {
  const terminalRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    const term = new Terminal();
    if (terminalRef.current) {
      term.open(terminalRef.current);
      term.writeln('Welcome to Handex Term!');
      term.writeln('Login');
      term.write('Username: ');
    }

    return () => {
      term.dispose();
    };
  }, []);

  return (
    <div className="handterm-container">
      <div ref={terminalRef} className="terminal-container" />
      <div className="editor-container">
        <CodeMirrorEditor initialValue="// Your initial code here" />
      </div>
    </div>
  );
};

export default HandTerm;

  4. Add some CSS for layout:

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

.terminal-container {
  flex: 1;
  background-color: black;
}

.editor-container {
  flex: 1;
  height: 50%;
}

This setup creates a CodeMirrorEditor component that integrates vim keybindings using @replit/codemirror-vim and uses it within the HandTerm component alongside xterm.js. The onChange prop in CodeMirrorEditor handles editor changes and can be used to propagate changes to the parent component if needed.

The error you are encountering indicates that some dependencies required by @replit/codemirror-vim are not resolved. This can happen if the packages are not installed or if there are some issues with the package resolution.

To resolve this issue, you need to ensure that the required dependencies are installed. Specifically, you need to install @codemirror/language, @codemirror/search, and @codemirror/commands.

You can do this by running the following command:

yarn add @codemirror/language @codemirror/search @codemirror/commands

After installing these dependencies, restart your development server and try again. If the issue persists, ensure that your vite.config.js (or vite.config.ts) is properly configured to handle these modules.

Here's a basic example of what your vite.config.js might look like:

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

export default defineConfig({
  plugins: [react()],
  resolve: {
    alias: {
      '@codemirror/language': '@codemirror/language',
      '@codemirror/search': '@codemirror/search',
      '@codemirror/commands': '@codemirror/commands',
    },
  },
});

By ensuring the necessary dependencies are installed and properly resolving any potential issues with module resolution in your vite.config.js, you should be able to resolve the errors you are encountering.

The error indicates that Vite is unable to resolve the codemirror import. This could be due to a missing package or an incorrect package name.

First, ensure that the codemirror package is installed:

yarn add codemirror

If the package is already installed and you are still encountering the issue, it might be due to the way Vite resolves packages. Ensure that your vite.config.js is correctly set up to handle these imports.

Here's a complete example of how to set up your CodeMirrorEditor component and vite.config.js:

vite.config.js

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

export default defineConfig({
  plugins: [react()],
  resolve: {
    alias: {
      'codemirror': 'codemirror',
    },
  },
});

src/components/CodeMirrorEditor.tsx

import React, { useEffect, useRef } from 'react';
import { EditorView, basicSetup } from 'codemirror';
import { vim } from '@replit/codemirror-vim';
import { javascript } from '@codemirror/lang-javascript';
import 'codemirror/lib/codemirror.css';

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

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

  useEffect(() => {
    if (editorRef.current) {
      const view = new EditorView({
        doc: initialValue,
        extensions: [
          vim(), // Enable Vim keybindings
          basicSetup,
          javascript(),
          EditorView.updateListener.of((update) => {
            if (update.docChanged && onChange) {
              onChange(view.state.doc.toString());
            }
          }),
        ],
        parent: editorRef.current,
      });

      return () => view.destroy();
    }
  }, [initialValue, onChange]);

  return <div ref={editorRef} />;
};

export default CodeMirrorEditor;

src/components/HandTerm.tsx

import React, { useEffect, useRef } from 'react';
import { Terminal } from 'xterm';
import CodeMirrorEditor from './CodeMirrorEditor';
import 'xterm/css/xterm.css';
import 'codemirror/lib/codemirror.css';
import './HandTerm.css';

const HandTerm: React.FC = () => {
  const terminalRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    const term = new Terminal();
    if (terminalRef.current) {
      term.open(terminalRef.current);
      term.writeln('Welcome to Handex Term!');
      term.writeln('Login');
      term.write('Username: ');
    }

    return () => {
      term.dispose();
    };
  }, []);

  return (
    <div className="handterm-container">
      <div ref={terminalRef} className="terminal-container" />
      <div className="editor-container">
        <CodeMirrorEditor initialValue="// Your initial code here" />
      </div>
    </div>
  );
};

export default HandTerm;

src/components/HandTerm.css

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

.terminal-container {
  flex: 1;
  background-color: black;
}

.editor-container {
  flex: 1;
  height: 50%;
}

By ensuring the codemirror package is installed and properly configuring your Vite setup, you should be able to resolve the import issues and get your CodeMirrorEditor component working with Vim keybindings.

The error indicates that Vite is unable to resolve the @codemirror/lang-javascript import. This could be due to the package not being installed or an issue with the module resolution.

First, ensure that the @codemirror/lang-javascript package is installed:

yarn add @codemirror/lang-javascript

Next, update your vite.config.ts to ensure all necessary packages are properly resolved:

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

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [react()],
  base: '/',
  build: {
    target: 'esnext',
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
      '@codemirror/language': '@codemirror/language',
      '@codemirror/search': '@codemirror/search',
      '@codemirror/commands': '@codemirror/commands',
      '@codemirror/lang-javascript': '@codemirror/lang-javascript', // Add this line
    },
  },
});

Ensure that your CodeMirrorEditor.tsx is correctly importing and using the @codemirror/lang-javascript module:

src/components/CodeMirrorEditor.tsx

import React, { useEffect, useRef } from 'react';
import { EditorView, basicSetup } from 'codemirror';
import { vim } from '@replit/codemirror-vim';
import { javascript } from '@codemirror/lang-javascript';
import 'codemirror/lib/codemirror.css';

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

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

  useEffect(() => {
    if (editorRef.current) {
      const view = new EditorView({
        doc: initialValue,
        extensions: [
          vim(), // Enable Vim keybindings
          basicSetup,
          javascript(),
          EditorView.updateListener.of((update) => {
            if (update.docChanged && onChange) {
              onChange(view.state.doc.toString());
            }
          }),
        ],
        parent: editorRef.current,
      });

      return () => view.destroy();
    }
  }, [initialValue, onChange]);

  return <div ref={editorRef} />;
};

export default CodeMirrorEditor;

After making sure that all necessary packages are installed and properly configured in your vite.config.ts, restart your development server. This should resolve the import issues and successfully load the @codemirror/lang-javascript module.

To add TypeScript and Markdown functionality to your CodeMirrorEditor component, you'll need to install the relevant packages and update your component to include the necessary extensions.

Step 1: Install the Required Packages

yarn add @codemirror/lang-typescript @codemirror/lang-markdown

Step 2: Update the CodeMirrorEditor Component

Modify the CodeMirrorEditor component to include TypeScript and Markdown support.

// src/components/CodeMirrorEditor.tsx
import React, { useEffect, useRef } from 'react';
import { EditorView, basicSetup } from 'codemirror';
import { vim } from '@replit/codemirror-vim';
import { javascript } from '@codemirror/lang-javascript';
import { markdown } from '@codemirror/lang-markdown';
import { typescript } from '@codemirror/lang-typescript';
import 'codemirror/lib/codemirror.css';

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

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

  useEffect(() => {
    if (editorRef.current) {
      const extensions = [vim(), basicSetup, EditorView.updateListener.of((update) => {
        if (update.docChanged && onChange) {
          onChange(view.state.doc.toString());
        }
      })];

      switch (language) {
        case 'typescript':
          extensions.push(typescript());
          break;
        case 'markdown':
          extensions.push(markdown());
          break;
        case 'javascript':
        default:
          extensions.push(javascript());
          break;
      }

      const view = new EditorView({
        doc: initialValue,
        extensions,
        parent: editorRef.current,
      });

      return () => view.destroy();
    }
  }, [initialValue, language, onChange]);

  return <div ref={editorRef} />;
};

export default CodeMirrorEditor;

Step 3: Update Your Parent Component to Pass the Language Prop

Ensure your parent component passes the language prop to CodeMirrorEditor:

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

const HandTerm: React.FC = () => {
  const terminalRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    const term = new Terminal();
    if (terminalRef.current) {
      term.open(terminalRef.current);
      term.writeln('Welcome to Handex Term!');
      term.writeln('Login');
      term.write('Username: ');
    }

    return () => {
      term.dispose();
    };
  }, []);

  return (
    <div className="handterm-container">
      <div ref={terminalRef} className="terminal-container" />
      <div className="editor-container">
        <CodeMirrorEditor initialValue="// Your initial code here" language="typescript" />
      </div>
    </div>
  );
};

export default HandTerm;

This setup allows you to switch between JavaScript, TypeScript, and Markdown modes by changing the language prop passed to the CodeMirrorEditor component. You can further customize the CodeMirrorEditor component to dynamically support more languages or add more features as needed.

If there's no dedicated TypeScript language package for codemirror, you can still use the one provided by @codemirror/lang-javascript with TypeScript support enabled. This package supports both JavaScript and TypeScript.

Here's how you can update your CodeMirrorEditor component to include TypeScript and Markdown functionality using the correct package:

Step 1: Ensure Required Packages are Installed

You should already have the necessary packages installed:

yarn add @codemirror/lang-javascript @codemirror/lang-markdown

Step 2: Update the CodeMirrorEditor Component

Modify the CodeMirrorEditor component to include support for both TypeScript and Markdown.

// src/components/CodeMirrorEditor.tsx
import React, { useEffect, useRef } from 'react';
import { EditorView, basicSetup } from 'codemirror';
import { vim } from '@replit/codemirror-vim';
import { javascript } from '@codemirror/lang-javascript';
import { markdown } from '@codemirror/lang-markdown';
import 'codemirror/lib/codemirror.css';

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

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

  useEffect(() => {
    if (editorRef.current) {
      const extensions = [vim(), basicSetup, EditorView.updateListener.of((update) => {
        if (update.docChanged && onChange) {
          onChange(view.state.doc.toString());
        }
      })];

      switch (language) {
        case 'typescript':
          extensions.push(javascript({ typescript: true }));
          break;
        case 'markdown':
          extensions.push(markdown());
          break;
        case 'javascript':
        default:
          extensions.push(javascript());
          break;
      }

      const view = new EditorView({
        doc: initialValue,
        extensions,
        parent: editorRef.current,
      });

      return () => view.destroy();
    }
  }, [initialValue, language, onChange]);

  return <div ref={editorRef} />;
};

export default CodeMirrorEditor;

Step 3: Update the Parent Component

Ensure your parent component passes the language prop to CodeMirrorEditor:

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

const HandTerm: React.FC = () => {
  const terminalRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    const term = new Terminal();
    if (terminalRef.current) {
      term.open(terminalRef.current);
      term.writeln('Welcome to Handex Term!');
      term.writeln('Login');
      term.write('Username: ');
    }

    return () => {
      term.dispose();
    };
  }, []);

  return (
    <div className="handterm-container">
      <div ref={terminalRef} className="terminal-container" />
      <div className="editor-container">
        <CodeMirrorEditor initialValue="// Your initial code here" language="typescript" />
      </div>
    </div>
  );
};

export default HandTerm;

Step 4: Add CSS for Layout

Ensure your CSS supports the layout:

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

.terminal-container {
  flex: 1;
  background-color: black;
}

.editor-container {
  flex: 1;
  height: 50%;
}

This setup will allow you to switch between JavaScript, TypeScript, and Markdown modes by changing the language prop passed to the CodeMirrorEditor component. The @codemirror/lang-javascript package supports both JavaScript and TypeScript when configured correctly.

The error indicates that Vite is unable to resolve the codemirror/lib/codemirror.css import. The codemirror package might have updated its structure, and the CSS file might be located elsewhere or named differently.

To resolve this, you can try the following:

  1. Check the codemirror Package Structure: Look into the node_modules/codemirror directory to find the correct path for the CSS file. It might be under a different directory or with a different name.

  2. Update the Import Path: Once you find the correct path, update the import statement in your CodeMirrorEditor.tsx file.

If the CSS file is not found, you might need to use a different package for the CSS or manually add the required styles.

Step-by-Step Solution:

  1. Check for the Correct Path: Open node_modules/codemirror/ and locate the CSS file.

  2. Update the Import Path: If the CSS file is found under a different path, update your import statement in CodeMirrorEditor.tsx.

For example, if the CSS file is under node_modules/codemirror/theme/, you should update the import to:

import 'codemirror/theme/theme.css';

If you cannot find the CSS file, you can manually add the required styles to your project.

Alternative: Use a CSS File from Another Source

If the codemirror package no longer provides a CSS file, you can include the required styles from an online source or a different package.

Here's an example of how to include the CSS from a CDN:

  1. Add the CSS Link in index.html:

    <!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>HandTerm</title>
  <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.65.5/codemirror.min.css">
</head>
<body>
  <div id="root"></div>
  <script type="module" src="/src/main.tsx"></script>
</body>
</html>

  2. Remove the CSS Import from CodeMirrorEditor.tsx:

    // src/components/CodeMirrorEditor.tsx
import React, { useEffect, useRef } from 'react';
import { EditorView, basicSetup } from 'codemirror';
import { vim } from '@replit/codemirror-vim';
import { javascript } from '@codemirror/lang-javascript';
import { markdown } from '@codemirror/lang-markdown';

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

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

  useEffect(() => {
    if (editorRef.current) {
      const extensions = [
        vim(),
        basicSetup,
        EditorView.updateListener.of((update) => {
          if (update.docChanged && onChange) {
            onChange(view.state.doc.toString());
          }
        }),
      ];

      switch (language) {
        case 'typescript':
          extensions.push(javascript({ typescript: true }));
          break;
        case 'markdown':
          extensions.push(markdown());
          break;
        case 'javascript':
        default:
          extensions.push(javascript());
          break;
      }

      const view = new EditorView({
        doc: initialValue,
        extensions,
        parent: editorRef.current,
      });

      return () => view.destroy();
    }
  }, [initialValue, language, onChange]);

  return <div ref={editorRef} />;
};

export default CodeMirrorEditor;

By including the CSS from a CDN, you can avoid issues related to missing or mislocated CSS files in the codemirror package. This should resolve the error and allow you to continue developing your application.

To find the location of the *.css file from the command line, you can use the find command on Unix-like systems (such as Linux and macOS) or the dir command on Windows. Here are the steps for both systems:

On Unix-like Systems (Linux or macOS)

  1. Navigate to the node_modules/codemirror directory:

    cd node_modules/codemirror

  2. Use the find command to locate CSS files:

    find . -name "*.css"

This will list all .css files within the codemirror directory and its subdirectories.

On Windows

  1. Navigate to the node_modules/codemirror directory:

    cd node_modules\codemirror

  2. Use the dir command to locate CSS files:

    dir /s /b *.css

This will list all .css files within the codemirror directory and its subdirectories.

Example Output

For Unix-like systems:

./lib/codemirror.css
./theme/abcdef.css
./theme/ambiance.css
...

For Windows:

C:\path\to\project\node_modules\codemirror\lib\codemirror.css
C:\path\to\project\node_modules\codemirror\theme\abcdef.css
C:\path\to\project\node_modules\codemirror\theme\ambiance.css
...

Update Your Import Path

Once you have identified the correct path, update your import statement in CodeMirrorEditor.tsx:

import 'codemirror/lib/codemirror.css'; // Update this path if necessary

For example, if the file is located in the lib directory, keep it as is:

import 'codemirror/lib/codemirror.css';

If the file is located in a different directory, update the path accordingly:

import 'codemirror/theme/abcdef.css'; // Example if located in the theme directory

By using these commands, you can efficiently locate the CSS files within the codemirror package and update your import paths accordingly.

If the Get-ChildItem command returns no results, it indicates that there might not be any .css files within the codemirror package. This could be due to changes in the package structure.

Let's explore alternative ways to ensure you have the necessary CSS for CodeMirror:

  1. Check the Documentation: Refer to the official documentation or repository of codemirror to see if there are any updates on how to include the CSS.

  2. Use a CDN for the CSS: If the package no longer includes the CSS, you can use a CDN to include the styles in your index.html.

Using a CDN for CodeMirror CSS

Here’s how you can include the CodeMirror CSS from a CDN:

  1. Add the CSS Link in index.html:

    <!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>HandTerm</title>
  <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.65.5/codemirror.min.css">
</head>
<body>
  <div id="root"></div>
  <script type="module" src="/src/main.tsx"></script>
</body>
</html>

  2. Remove the CSS Import from CodeMirrorEditor.tsx:

    // src/components/CodeMirrorEditor.tsx
import React, { useEffect, useRef } from 'react';
import { EditorView, basicSetup } from 'codemirror';
import { vim } from '@replit/codemirror-vim';
import { javascript } from '@codemirror/lang-javascript';
import { markdown } from '@codemirror/lang-markdown';

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

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

  useEffect(() => {
    if (editorRef.current) {
      const extensions = [
        vim(),
        basicSetup,
        EditorView.updateListener.of((update) => {
          if (update.docChanged && onChange) {
            onChange(view.state.doc.toString());
          }
        }),
      ];

      switch (language) {
        case 'typescript':
          extensions.push(javascript({ typescript: true }));
          break;
        case 'markdown':
          extensions.push(markdown());
          break;
        case 'javascript':
        default:
          extensions.push(javascript());
          break;
      }

      const view = new EditorView({
        doc: initialValue,
        extensions,
        parent: editorRef.current,
      });

      return () => view.destroy();
    }
  }, [initialValue, language, onChange]);

  return <div ref={editorRef} />;
};

export default CodeMirrorEditor;

Alternative: Manually Add the Required Styles

If using a CDN is not an option, you can manually download the required CSS file and include it in your project:

  1. Download the CSS File: Download the CSS file from CodeMirror GitHub Releases or from a CDN like cdnjs.

  2. Include the CSS File in Your Project: Place the downloaded CSS file in a directory within your project, for example, public/css.

  3. Update the Import Path in CodeMirrorEditor.tsx:

    import 'path_to_your_css/codemirror.css'; // Update this path to where you placed the CSS file

By following these steps, you can ensure that your project has the necessary CodeMirror CSS, either by using a CDN or by manually including the styles.

The Not an editor command ":q" message indicates that the Vim emulation within CodeMirror does not recognize the :q command, which is typically used to quit the Vim editor. This behavior is expected because CodeMirror's Vim mode does not support all the commands available in the full Vim editor.

However, you can customize the behavior of the CodeMirror Vim mode to handle the :q command or similar commands. You can achieve this by extending the Vim commands within your CodeMirrorEditor component.

Here’s how you can add custom Vim commands to your CodeMirrorEditor component to support :q:

Step-by-Step Solution

  1. Extend the Vim Commands: Add custom commands to handle :q within the CodeMirrorEditor component.

  2. Update the CodeMirrorEditor Component: Modify your CodeMirrorEditor component to include the custom Vim command.

Example Code

// src/components/CodeMirrorEditor.tsx
import React, { useEffect, useRef } from 'react';
import { EditorView, basicSetup } from 'codemirror';
import { vim } from '@replit/codemirror-vim';
import { javascript } from '@codemirror/lang-javascript';
import { markdown } from '@codemirror/lang-markdown';
import 'codemirror/lib/codemirror.css';

// Extend Vim commands to add custom command handling
vim().constructor.defineEx('q', '', (cm: any) => {
  alert('Quit command invoked');
  // You can add your custom logic here, for example:
  // cm.getWrapperElement().style.display = 'none';
});

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

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

  useEffect(() => {
    if (editorRef.current) {
      const extensions = [
        vim(),
        basicSetup,
        EditorView.updateListener.of((update) => {
          if (update.docChanged && onChange) {
            onChange(view.state.doc.toString());
          }
        }),
      ];

      switch (language) {
        case 'typescript':
          extensions.push(javascript({ typescript: true }));
          break;
        case 'markdown':
          extensions.push(markdown());
          break;
        case 'javascript':
        default:
          extensions.push(javascript());
          break;
      }

      const view = new EditorView({
        doc: initialValue,
        extensions,
        parent: editorRef.current,
      });

      return () => view.destroy();
    }
  }, [initialValue, language, onChange]);

  return <div ref={editorRef} />;
};

export default CodeMirrorEditor;

Explanation

  • Custom Vim Command: The vim().constructor.defineEx method is used to define an extended Vim command. In this case, the :q command is added, and a simple alert is shown when the command is invoked. You can replace the alert with any custom logic you need, such as closing the editor or hiding the container.
  • Editor Setup: The rest of the CodeMirrorEditor component remains the same, setting up the editor with the necessary extensions and language modes.

Custom Logic Example

If you want to add custom logic to hide the editor or perform other actions, you can modify the command handler:

vim().constructor.defineEx('q', '', (cm: any) => {
  const editorElement = cm.getWrapperElement();
  if (editorElement) {
    editorElement.style.display = 'none'; // Hide the editor
  }
});

By extending the Vim commands and adding custom logic, you can handle commands like :q within the CodeMirror Vim mode, enhancing the functionality and user experience of your web-based TUI.

The error you're encountering indicates that TypeScript is not recognizing the defineEx method on the vim object. This could be due to a mismatch in the type definitions provided by @replit/codemirror-vim.

To properly extend Vim commands in CodeMirror and avoid TypeScript errors, you can directly interact with the underlying Vim API provided by @replit/codemirror-vim.

Step-by-Step Solution

  1. Import the Necessary Modules: Ensure you import the necessary modules and types from @replit/codemirror-vim.

  2. Extend Vim Commands: Use the correct method to extend Vim commands within your CodeMirrorEditor component.

Example Code

Here’s the updated code to include custom Vim commands without TypeScript errors:

// src/components/CodeMirrorEditor.tsx
import React, { useEffect, useRef } from 'react';
import { EditorView, basicSetup } from 'codemirror';
import { vim, Vim } from '@replit/codemirror-vim';
import { javascript } from '@codemirror/lang-javascript';

Explanation

  • Importing Vim: The Vim object from @replit/codemirror-vim is imported to define custom commands. The vim function is used to enable Vim mode.
  • Defining Custom Commands: The Vim.defineEx method is used to define the :q command. You can add any custom logic within this method.

Exiting Vim Mode without :q

If you want to provide a way to exit Vim mode or hide the editor without using :q, you can add a button or another UI element that triggers the desired behavior.

Here’s an example of adding a button to hide the editor:

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

  useEffect(() => {
    if (editorRef.current) {
      const extensions = [
        vim(),
        basicSetup,
        EditorView.updateListener.of((update) => {
          if (update.docChanged && onChange) {
            onChange(view.state.doc.toString());
          }
        }),
      ];

      switch (language) {
        case 'typescript':
          extensions.push(javascript({ typescript: true }));
          break;
        case 'markdown':
          extensions.push(markdown());
          break;
        case 'javascript':
        default:
          extensions.push(javascript());
          break;
      }

      const view = new EditorView({
        doc: initialValue,
        extensions,
        parent: editorRef.current,
      });

      return () => view.destroy();
    }
  }, [initialValue, language, onChange]);

  const handleHideEditor = () => {
    if (editorRef.current) {
      editorRef.current.style.display = 'none';
    }
  };

  return (
    <div>
      <div ref={editorRef} />
      <button onClick={handleHideEditor}>Hide Editor</button>
    </div>
  );
};

export default CodeMirrorEditor;

This example includes a button that, when clicked, hides the editor by setting its display

You're right; a TUI (Text-based User Interface) typically does not include buttons and relies on keyboard commands. To address the requirement of exiting Vim mode in a CodeMirror instance configured for Vim without using :q, you can define a custom command that can be invoked using a keyboard shortcut.

Let's create a custom Vim command that can be triggered by a key sequence, such as :wq or similar, to simulate exiting the editor. Here’s how you can do it:

Step-by-Step Solution

  1. Extend Vim Commands: Define a custom Vim command to handle the exit functionality.

  2. Update the CodeMirrorEditor Component: Update the component to include the custom Vim command.

Example Code

// src/components/CodeMirrorEditor.tsx
import React, { useEffect, useRef } from 'react';
import { EditorView, basicSetup } from 'codemirror';
import { vim, Vim } from '@replit/codemirror-vim';
import { javascript } from '@codemirror/lang-javascript';
import { markdown } from '@codemirror/lang-markdown';
import 'codemirror/lib/codemirror.css';

// Extend Vim commands to add custom command handling
Vim.defineEx('wq', '', (cm: any) => {
  cm.save(); // Save the document (if applicable)
  alert('Save and Quit command invoked');
  // You can add your custom logic here, for example:
  const editorElement = cm.getWrapperElement();
  if (editorElement) {
    editorElement.style.display = 'none'; // Hide the editor
  }
});

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

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

  useEffect(() => {
    if (editorRef.current) {
      const extensions = [
        vim(),
        basicSetup,
        EditorView.updateListener.of((update) => {
          if (update.docChanged && onChange) {
            onChange(view.state.doc.toString());
          }
        }),
      ];

      switch (language) {
        case 'typescript':
          extensions.push(javascript({ typescript: true }));
          break;
        case 'markdown':
          extensions.push(markdown());
          break;
        case 'javascript':
        default:
          extensions.push(javascript());
          break;
      }

      const view = new EditorView({
        doc: initialValue,
        extensions,
        parent: editorRef.current,
      });

      return () => view.destroy();
    }
  }, [initialValue, language, onChange]);

  return <div ref={editorRef} />;
};

export default CodeMirrorEditor;

Explanation

  • Custom Vim Command: The Vim.defineEx method is used to define a custom command :wq. This command can be used to save the document (if applicable) and then hide the editor. You can replace the alert with any custom logic you need.
  • Editor Setup: The rest of the CodeMirrorEditor component remains the same, setting up the editor with the necessary extensions and language modes.

Using the Custom Command

  • Entering Command Mode: Press Esc to enter Command mode in Vim.
  • Using the Custom Command: Type :wq and press Enter to invoke the custom command, which will save and quit the editor.

By defining a custom Vim command and using keyboard shortcuts, you can simulate the behavior of exiting Vim mode in a CodeMirror instance without relying on buttons or mouse interactions, maintaining the TUI experience.

You are correct that :wq and :q are core commands in Vim, and it would be cumbersome to redefine each core command manually. Fortunately, @replit/codemirror-vim should support these core commands out of the box.

If you are encountering issues with these commands, it might be due to how @replit/codemirror-vim is integrated or configured. Let’s ensure that the Vim mode is correctly set up in your CodeMirrorEditor.

Here’s a revised approach:

Step-by-Step Solution

  1. Ensure Proper Installation: Make sure that all necessary packages are correctly installed.

  2. Check for Correct Integration: Ensure that @replit/codemirror-vim is correctly integrated and configured in your CodeMirror setup.

Example Code

Let’s start by checking the integration and ensuring the setup is correct:

// src/components/CodeMirrorEditor.tsx
import React, { useEffect, useRef } from 'react';
import { EditorView, basicSetup } from 'codemirror';
import { vim } from '@replit/codemirror-vim';
import { javascript } from '@codemirror/lang-javascript';
import { markdown } from '@codemirror/lang-markdown';
import 'codemirror/lib/codemirror.css';

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

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

  useEffect(() => {
    if (editorRef.current) {
      const extensions = [
        vim(),
        basicSetup,
        EditorView.updateListener.of((update) => {
          if (update.docChanged && onChange) {
            onChange(view.state.doc.toString());
          }
        }),
      ];

      switch (language) {
        case 'typescript':
          extensions.push(javascript({ typescript: true }));
          break;
        case 'markdown':
          extensions.push(markdown());
          break;
        case 'javascript':
        default:
          extensions.push(javascript());
          break;
      }

      const view = new EditorView({
        doc: initialValue,
        extensions,
        parent: editorRef.current,
      });

      return () => view.destroy();
    }
  }, [initialValue, language, onChange]);

  return <div ref={editorRef} />;
};

export default CodeMirrorEditor;

Ensure Proper Configuration

  1. Check Version Compatibility: Ensure that you are using compatible versions of codemirror and @replit/codemirror-vim.

  2. Check Dependencies: Ensure all dependencies are correctly installed:

    yarn add codemirror @replit/codemirror-vim @codemirror/lang-javascript @codemirror/lang-markdown

  3. Verify Browser Console: Check the browser console for any errors related to CodeMirror or Vim integration.

Troubleshooting

  • Update Command Handling: If the core commands still do not work, you can try to explicitly add the commands using Vim.defineEx. This should not be necessary, but it can be a temporary workaround.
Vim.defineEx('q', '', (cm: any) => {
  const editorElement = cm.getWrapperElement();
  if (editorElement) {
    editorElement.style.display = 'none'; // Hide the editor
  }
});

Vim.defineEx('wq', '', (cm: any) => {
  cm.save(); // Save the document (if applicable)
  const editorElement = cm.getWrapperElement();
  if (editorElement) {
    editorElement.style.display = 'none'; // Hide the editor
  }
});

Conclusion

The core commands like :q and :wq should be supported by @replit/codemirror-vim without the need for manual definition. If they are not working as expected, it’s likely due to an issue with the setup or integration. Ensure that all dependencies are correctly installed and that there are no errors in the browser console. If issues persist, consider checking the official documentation or GitHub repository for any known issues or updates.
