Call Hierarchy Plus (CHP)

Call Hierarchy Plus is an enhanced Call Hierarchy extension for VS Code, specifically designed for C/C++ developers working on complex firmware (such as SoC development). It bridges the gap between direct function calls and indirect pointer assignments/callbacks.

📌 Features

The native VS Code Call Hierarchy often breaks when it encounters function pointers. CHP solves this by establishing a complete logic chain: Function Definition ➔ Pointer Assignment ➔ Pointer Invocation.

• Function Pointer Tracking: Seamlessly tracks through global variables, struct initializations, and local variables.
• Complex Declarations: Supports cross-line complex declarations (e.g., void (*fp)(int) = target).
• Struct Member Invocations: Precisely parses and tracks struct member calls like ops.on_rx(data).
• Deep Context Parsing: Uses a multiline context window to accurately identify assignments even when arguments span multiple lines.

🚀 Usage

1. Place your cursor on a function or function pointer in a C/C++ file.
2. Press Ctrl+Shift+C (or Cmd+Shift+C on macOS) to run Call Hierarchy Plus.
3. The Call Hierarchy Plus view will open in the sidebar, displaying the complete call chain.
4. Click on any node to navigate directly to the exact line of the function call or assignment.

🛠️ Requirements

• This extension is designed to work with C and C++ projects.
• It relies on the built-in C/C++ language features of VS Code (ensure you have the official Microsoft C/C++ extension installed and configured).
