🚀 Quick Start

Method 1: Hover Links (Recommended)

1. Hover your mouse over any symbol (variable, function, class, etc.)
2. Click the "Find All References" link in the hover tooltip
3. View all references in the References panel (uses references-view.findReferences)

Method 2: File CodeLens

1. Open any supported file (TypeScript, JavaScript, Vue, etc.)
2. Look for the "🔍 Find File References" link at the top of the file (line 1)
3. Click it to view all file references using TypeScript's file reference finder

Method 3: Toolbar Button (New!)

• The references button now appears immediately when you open a file from the sidebar
• No need to click into the editor to focus it first
• Click the button in the editor toolbar for instant file references

Method 4: Keyboard Shortcuts

• Symbol References: Ctrl+Alt+F12 (Mac: Cmd+Alt+F12)
• File References: Ctrl+Shift+F12 (Mac: Cmd+Shift+F12)

🔧 Configuration

Configure the extension behavior in your VSCode settings:

{
  "findAllReferences.supportedLanguages": [
    "typescript",
    "javascript",
    "typescriptreact",
    "javascriptreact",
    "vue"
  ],
  "findAllReferences.enableCodeLens": true,
  "findAllReferences.enableHover": true
}

Configuration Options

VSCode CodeLens Settings

Make sure CodeLens is enabled in your VSCode settings:

{
  "editor.codeLens": true,
  "typescript.referencesCodeLens.enabled": true,
  "javascript.referencesCodeLens.enabled": true
}

🛠️ Technical Implementation

Symbol Reference Finding

• Hover Provider: Detects symbols at hover position and shows clickable link
• Command: findAllReferences.findReferences
• Implementation: Calls VSCode's built-in references-view.findReferences command
• Parameters: Passes document URI and position from hover or cursor location

File Reference Finding

• CodeLens Provider: Shows "🔍 Find File References" link at the beginning of each file
• Toolbar Button: Always visible when files are open (no focus required)
• Command: findAllReferences.findFileReferences
• Implementation: Calls TypeScript extension's typescript.findAllFileReferences command
• Scope: Finds all import/require statements referencing the current file

Key Features

• Smart Parameter Passing: Hover links pass exact position to reference finder
• Language Filtering: Only activates for configured language types
• Configurable Components: Enable/disable CodeLens and Hover independently
• Immediate Toolbar Access: Button shows instantly when opening files
• Fallback Handling: Graceful error handling when commands are unavailable
• Enhanced Debug Logging: Comprehensive output channel logging for troubleshooting

🎯 Use Cases

TypeScript/JavaScript Development

// Hover over 'myFunction' to see reference link
function myFunction() {
  return 'Hello World';
}

// Click "🔍 Find File References" CodeLens at top of file to see all imports

Vue Component Development

<!-- TestComponent.vue -->
<template>
  <div>My Component</div>
</template>

<!-- Click "🔍 Find File References" to see where this component is imported -->

React Development

// Hover over component names, props, or functions
const MyComponent = () => {
  return <div>Hello</div>;
};

📋 Requirements

• VSCode: 1.74.0 or higher
• TypeScript Extension: For file reference finding (usually pre-installed)
• References View: For symbol reference display (built into VSCode)

🐛 Debugging & Troubleshooting

The extension provides detailed logging in the "Find All References" output channel:

1. Open Command Palette (Ctrl+Shift+P)
2. Run "View: Toggle Output"
3. Select "Find All References" from the dropdown
4. View detailed logs of hover events, command executions, and errors
