C/C++ Typedef Hover

A Visual Studio Code extension that provides enhanced hover information for typedef definitions in C and C++ files. When hovering over a type identifier, this extension shows the complete type definition with source location links.

Features

This extension adds enhanced hover functionality for C and C++ files:

• Shows complete typedef definitions when hovering over custom types
• Displays the full type definition including nested structures
• Provides direct links to type definitions in source code
• Supports multi-line typedef declarations
• Handles complex type definitions with nested braces

For example, when you hover over a custom type:

typedef struct {
    int x;
    int y;
} Point;

Point p; // Hover over "Point" to see the complete definition

The hover tooltip will show:

• A link to the type definition location
• The complete type definition in a formatted code block

Usage

The extension automatically activates for C and C++ files. Simply hover over any symbol to view its type definition:

1. Open a C or C++ file
2. Hover over any custom type or variable
3. The hover tooltip will display the complete type definition if available

Requirements

This extension requires:

• Visual Studio Code version 1.x.x or higher
• C/C++ files in your workspace

Extension Settings

This extension does not contribute any additional settings.

Known Issues

The definition body is located with line-based heuristics, not a real C parser, so the following limits apply:

• The upward search for the start of a definition stops after 50 lines; the forward search for the closing brace stops after 200 lines. Definitions longer than that are truncated without warning.
• Definitions where the type name and the body are separated by preprocessor conditionals (#if / #else) may resolve to the wrong branch.
• Variable declarations are recognized only in the shape <keyword> <type> <name>;; forms such as static const int x; are not matched.

If you encounter any other problems, please report them on the GitHub repository.
