StructVisualizer

Parse and visualize C/C++ struct memory layout with alignment, padding, pointers, and packing control.

Features

• Right-click any struct in a C/C++ file → “Visualize Struct”
• Memory layout visualization:
  • 8-byte rows (configurable via packing)
  • Color-coded fields:
    • 🟢 Light green: normal data
    • 🔵 Light blue: pointers
    • 🟣 Plum: function pointers
    • 🔴 Red ("PAD"): padding bytes
• Bit-field support with vertical label stacking
• Byte-width slider for zoom control
• Automatic type resolution using VS Code’s C/C++ extension (cpptools)
• User-configurable exclusion paths to avoid build/backup files
• Manual type definition fallback for unresolved types
• “Add Struct to JSON” to save computed size/alignment

Requirements

• VS Code
• C/C++ extension (for type resolution)

Usage

1. Open a .c or .h file
2. Place cursor inside a struct or typedef struct
3. Right-click → “Visualize Struct”
4. Adjust packing or zoom as needed

Settings

• struct-visualizer.typeResolver.excludePaths:
  Array of globs to exclude when resolving types (e.g., ["**/build/**", "**/*.bak"])

Built for embedded and systems developers who need to verify struct memory layout.
