An extension for visualizing execution flows in multithreaded C++ programs. Automatically analyzes your code and generates an interactive graph showing how threads, mutexes, and other synchronization objects interact.
Installation
Launch VS Code Quick Open (Ctrl+P), paste the following command, and press enter.
Multithread Inspector is an extension for static analysis and visualization of thread usage and synchronization in C++ code. It helps you understand, debug, and document multithreaded logic by providing interactive thread flow graphs and detailed reports.
Features
Thread Flow Graph Visualization:
Generates an interactive graph showing thread creation, synchronization primitives, and their relationships in your C++ code.
Context Analysis:
Highlights threads created inside loops and conditionals for easier detection of potential concurrency issues.
Synchronization Mapping:
Visualizes usage of mutexes, atomics, condition variables, and other synchronization primitives.
Clickable Navigation:
Click on graph nodes to jump directly to relevant lines in your source code.
Textual Reports:
Provides a summary and detailed report of thread and synchronization usage.
Getting Started
Install the extension from the VSCode Marketplace.
Open a C++ file with threading code.
Run the analysis:
Press Ctrl+Shift+T (Windows/Linux) or Cmd+Shift+T (macOS).
Or right-click in the editor and select Analyze Thread Flow.
View the results in the "C++ Thread Flow Graph" panel.
Supported Threading Constructs
std::thread
std::async
pthread_create
std::mutex, std::lock_guard, std::unique_lock
std::condition_variable
std::atomic
std::shared_ptr (for shared data)
Basic detection of thread creation in loops and conditionals
Requirements

Extension Settings
No custom settings yet. All features work out-of-the-box.
Known Issues
Analysis is static and may not detect all dynamic/threading patterns.
Complex macro-generated or template-based threading code may not be fully supported.
Only basic context analysis for loops and conditionals.
