Parallel Stacks is a Visual Studio Code extension that visualizes call stacks from multiple threads in a single, merged graph view. It is inspired by the "Parallel Stacks" window in Visual Studio, serving as a powerful tool for debugging multi-threaded C/C++ applications.
🛠 Usage
Start Debugging: Launch your debug session (works best with C++/Native debuggers).
Break Execution: Hit a breakpoint or pause execution manually.
Open View: Launch the command "Show Parallel Stacks" from the Command Palette (Ctrl/Cmd + Shift + P).
Interact:
Scroll/Pinch to zoom.
Click-and-drag to pan.
Click on frames to open the file.
Hover to highlight branches.
🚀 Features
🔍 Unified Graph Visualization
Multi-thread Aggregation: Groups threads with identical call stacks into a single branch to reduce complexity.
Top-Down & Bottom-Up: View the execution flow as a tree, making it easy to identify common ancestors and execution paths.
Dynamic Zoom & Pan: Fluidly explore complex multi-threaded environments with full zoom and pan support.
⚡ Interactive Debugging
Active Frame Highlight: Instantly see which stack frame is currently active in both the graph and the editor (highlighted with a green gutter arrow).
Source Code Navigation: Click on any node (stack frame) to navigate directly to the corresponding line in your source code.
Branch Tracing: Hover over any node to highlight the entire path down to the root, making stack tracing effortless.
Thread Management: Split out specific threads into their own branches or merge them back for custom visualization.
🎨 Modern UI/UX
VS Code Theme Integration: Automatically uses your active editor colors for a seamless experience.
