Code Fold Manager

Code Fold Manager is a VS Code extension that adds a native editor title action for folding top-level functions in the active file.

Features

• Adds a Code Fold Manager: Toggle Top-Level Functions action to the editor title bar.
• First click folds top-level functions in the active editor.
• Second click unfolds all folded regions in the file.
• Supports common brace-based languages and Python top-level def blocks.
• Uses lightweight parsing so it works without language-specific dependencies.

How It Works

The extension scans the active document for top-level function ranges:

• Brace-based languages use pattern matching plus brace-depth checks.
• Python files use indentation to detect top-level function bodies.

Nested functions are ignored. The command only targets top-level functions.

Install Locally

1. Open this folder in VS Code.
2. Press F5 to launch an Extension Development Host.
3. Open a code file.
4. Click the fold icon in the editor title bar.

You can also install the packaged VSIX:

1. Run npx @vscode/vsce package.
2. Install the generated .vsix with code --install-extension code-fold-manager-0.0.1.vsix.

Command

• Code Fold Manager: Toggle Top-Level Functions

Limitations

• The detector uses lightweight pattern matching, so uncommon syntax styles may not be matched perfectly.
• The toggle state resets when the document changes.
• Unfold uses VS Code's Unfold All, so it expands all folded regions, not just those created by the extension.
