CProtoGen is a versatile Python library and command-line tool designed for developers who need to streamline the process of generating C function prototypes from source files. With CProtoGen, you can effortlessly create and update header files based on your existing C code, making it an invaluable asset for any C development workflow.

Key Features

• Generate C Function Prototypes: Automatically derive function prototypes from C source files, ensuring your header files are always up-to-date.
• Flexible Integration: Use CProtoGen as a Python library or directly from the command line, adapting to your preferred development style.

Usage Examples

Library Integration

Easily generate prototypes using the CProtoGen API:

from cprotogen.generator import generate_prototypes

source_files = ["file1.c", "file2.c", "file3.c"]
for source in source_files:
    header = source.replace(".c", ".h")
    generate_prototypes(source, header, overwrite=True)
    print(f"Updated {header} with prototypes from {source}")

Command-Line Tool

Leverage the command-line interface for quick access:

# Generate prototypes and create/update a header file
cprotogen path/to/source.c --header path/to/header.h

# Generate prototypes and overwrite existing header file
cprotogen path/to/source.c --header path/to/existing_header.h --overwrite

# Display help information
cprotogen -h

Generating Prototypes with Example Code

Here’s how you can generate prototypes based on your C files:

1. For a Simple Function:

generate_prototypes("hello.c", "hello.h")

This will produce the header file hello.h containing the necessary prototypes.

2. Updating an Existing Header:

# Update your header as your source code evolves
generate_prototypes("hello.c", "hello.h", overwrite=True)

This ensures that your prototypes are in sync with the latest function definitions.

3. Generate Prototypes Without Header File:

prototypes = generate_prototypes("hello.c")
print(prototypes)  # Outputs the function prototypes directly.

CProtoGen is designed to enhance your workflow by reducing manual errors, saving time, and automating repetitive tasks in C programming. Simplify your development process with CProtoGen today!
