LineClip

Quickly copy file path, line number, and line content to clipboard with a single click.

LineClip is a VS Code extension that helps you quickly copy code references for sharing, documentation, or issue reporting. It's a port of the LineClip JetBrains plugin with full feature parity.

Features

• 🎯 Right-click convenience: Access from the editor context menu
• 📋 Smart formatting: Copies in format: relative/path/to/file.ext:42 line_content (or absolute path via alternate command)
• ✨ Clean output: Automatically trims leading and trailing whitespace
• 💬 Visual feedback: Status bar message shows preview of copied content
• ⌨️ Keyboard shortcut support: Configure your own shortcut (no default binding)
• 🗂️ Multi-root aware: Relative paths are resolved against the workspace folder that owns the file
