Code Depth

Code Depth

Code Depth is a VS Code extension that indicates the "logical depth" of your functions directly in the editor. By calculating the maximum execution path of your code, it helps you identify deeply nested logic and potential refactoring targets at a glance.

🚀 Features

• Logic Depth Annotations: Displays the "Depth" of a function as a ghost-text decoration next to the definition.

• Agnostic Analysis: Works with any language supported by a Language Server (LSP) that provides Call Hierarchy (Python, TypeScript, Rust, etc.).

• Smart Abstraction Filtering: Automatically stops analysis on highly reused functions to keep metrics meaningful.

🧠 How Depth is Calculated

The extension uses a recursive algorithm to traverse the Outgoing Call Hierarchy. To prevent performance lag and infinite loops, the search stops at a maximum depth of 5.

The "High Fan-In" Heuristic

To avoid "analysis paralysis" on common utility functions, the extension applies the following rule:

If a function has more than 5 incoming calls, it is treated as a stable abstraction.The drill-down stops there because high-frequency functions are typically well-tested utilities that do not contribute to the unique complexity of the specific feature you are currently analyzing.

🛠 Installation & Usage

• Open VS Code.
• Install the Code Depth extension via the 'extension' tab.
• Open any project and wait for your Language Server (like Pylance or TS Server) to initialize, then press ctrl + shift + p search for 'Toggle Code Depth'

🛡️ Requirements

Language Server: This extension relies on the vscode.prepareCallHierarchy command. Ensure you have a language extension installed (e.g., the Microsoft Python extension).
