MC: A C Pre-Preprocessors for Header Files Generation
A developer introduces MC, a C pre-preprocessor that generates .h header files from .c source files using custom comment macros, inspired by Pascal.

- MC stands for meta-c, acting as a pre-preprocessor for the C programming language.
- It solves the tedious task of switching between .c and .h files for declarations.
- Utilizes custom comment macros so code editors do not require extra language extensions.
- Inspired by Pascal, which allows implementation and interface in a single file.
A software developer has introduced a new tool named mc, which stands for meta-c, functioning as a pre-preprocessor for C. It generates .h header files for .c files by utilizing a custom macro syntax embedded within comments.
The creator shares with mixed feelings of guilt and pride that the application was purely "vibe-coded," yet it functions precisely the way they intended it to.
For beginners in C programming, constantly switching back and forth between a .c file and its corresponding .h file simply to update declarations can be frustrating. The mc tool was built specifically to tackle this exact pain point.
Developing custom workflow utilities like this highlights how programmers adapt traditional languages to suit modern coding habits. C's strict separation of header and implementation files is historically rooted in fast compilation times, but it can introduce friction for rapid prototyping. Leveraging comments as a carrier for macro instructions is a clever workaround because standard compilers simply ignore comments, ensuring full backwards compatibility.

The core idea behind this project was actually drawn from Pascal, a language where developers can write both the implementation and the interface within the very same file.
One of the major advantages of using comments as macros is that code editors do not need any new language extensions to recognize plain, regular C code. It truly offers the best of both worlds.
The workflow involves writing all the .h header content inside a single .c file using a custom comment macro syntax, feeding the file into mc, and letting the program automatically generate the required header file.
