CopyMate Pro

Stop manually copying files into ChatGPT. Browse your workspace, filter with .copyignore, and send structured code context to any LLM — right from VS Code.

What It Does

CopyMate Pro adds a dedicated sidebar panel to VS Code where you can:

• Browse your entire workspace file tree with checkbox selection
• Filter files and folders using a .copyignore file (same glob syntax as .gitignore)
• Copy selected file contents to clipboard in a structured, LLM-friendly format
• Copy your folder tree as a clean ASCII diagram

No more switching between your editor and browser to manually paste code. Select, copy, paste into Claude, ChatGPT, or GitHub Copilot — done.

Installation

From the VS Code Marketplace

Search for CopyMate Pro in the Extensions panel (Ctrl+Shift+X) and click Install.

From a .vsix File

code --install-extension copymate-pro-0.1.0.vsix

Or via the Extensions panel: ··· menu → Install from VSIX…

Getting Started

1. Open a workspace folder in VS Code
2. Click the CopyMate Pro icon in the Activity Bar (left sidebar)
3. Use checkboxes to select files
4. Click Copy Selected (📋) to copy file contents to clipboard
5. Paste directly into your LLM chat

Features

📁 File Tree with Checkboxes

A dedicated sidebar panel shows your full workspace tree. Click any checkbox to select individual files or entire folders. Selecting a folder automatically selects all files inside it.

🚫 .copyignore Support

Create a .copyignore file at your workspace root to exclude files and folders from the tree. Uses the same glob syntax as .gitignore.

# Example .copyignore
node_modules/
dist/
out/
*.env
.env.local
package-lock.json
*.vsix

The tree auto-refreshes whenever you save .copyignore.

📋 Copy Selected File Contents

Copies all checked files to clipboard in a structured format that LLMs parse well:

// ── src/extension.ts ──
import * as vscode from 'vscode';
// ... file content ...

// ── src/types.ts ──
export interface FileNode {
// ... file content ...

🌲 Copy Folder Tree

Copies your workspace structure as a tree diagram — useful for giving an LLM context about your project layout:

my-project/
├── src/
│   ├── commands/
│   │   └── index.ts
│   ├── core/
│   │   ├── ClipboardWriter.ts
│   │   └── IgnoreFilter.ts
│   └── extension.ts
├── package.json
└── README.md

⚡ Toolbar Actions

🖱️ Right-Click Context Menu

Right-click any file or folder in the CopyMate panel to quickly add it to .copyignore without opening the file manually.

Using .copyignore

Create a .copyignore file in the root of your workspace (same directory as package.json):

# Dependencies and build output
node_modules/
dist/
out/
.next/
build/

# Environment and secrets
*.env
.env.local
.env.production

# Lock files (usually too noisy for LLM context)
package-lock.json
yarn.lock
pnpm-lock.yaml

# Binary and generated files
*.vsix
*.png
*.jpg
*.svg

# IDE files
.vscode/
.idea/

Glob syntax supported:

• node_modules/ — ignore a folder by name anywhere in the tree
• *.env — ignore files matching a pattern
• src/generated/ — ignore a specific path

Requirements

• VS Code ^1.120.0
• A workspace folder must be open

Known Issues

• Binary files (images, fonts, compiled outputs) produce unreadable content when copied. Add them to .copyignore to exclude them from the tree.
• The extension requires at least one workspace folder to be open. It does not work with single-file windows.
