C Ifndef Headers

This project is a Python script that checks and updates C/C++ header files with proper #ifndef guards.

Features

• Recursively searches for .h, .cpp, .c, .hpp files in a specified directory (default is the current directory).
• Checks if each file contains the #ifndef, #define, and #endif preprocessor guards.
• If missing, automatically adds the necessary guards to the file.
• Supports dry-run mode where files are only checked, not modified.
• Custom guard name format based on the relative path of the file, ensuring uniqueness.

Installation

1. Clone the repository:

   git clone https://github.com/BaseMax/c-ifndef-headers.git
   cd c-ifndef-headers

2. Install dependencies (if any):

   pip install -r requirements.txt

Usage

Run the script to check and update header files:

python check_and_update.py /path/to/directory

To run in dry-run mode (only check files without modifying them):

python check_and_update.py /path/to/directory --dry-run

By default, the script will scan the current directory.
