# nonvariadic-printf

An implementation of printf + A pre-preprocessor to pass the code through before compiling.

Please read the blog post at https://blogginginhell.netlify.app/posts/printf-a-speculative-implementation to understand the idea.

## Requirements

- bash

- python3

- GNUMake

## How to use

- Write a program `main.cpp` using `my_printf`, the syntax is just like normal `printf` with some limitations in capabilities.

- Running `make` to run the pre-preprocessor and compile the program.

- `./main` to run the program.

- Additionally, you can inspect the `main.output.cpp` file to inspect the output generated by the pre-preprocessor.

## Limitations

- Only supports `%d`, `%f`, `%s` and `%p` format specifier.

- The `%f` format specifier only works with `double`.
