ft_printf — Patch Notes (v2.0)
## ✨ New Features - **Custom `ft_printf`**: Complete implementation with variadic handling and standard format specifiers. - **Output Modules**: - `print_char.c` — single char writes - `print_number.c` — signed/unsigned, hex, pointer handling - `utils.c` — `itoa_base`, `ft_strlen`, and helpers - **Public Header**: `includes/ft_printf.h` exposes prototypes and shared types. --- ## ⚙️ Build & Tooling Upgrades - **Modernized `Makefile`** - Clean variable management, per-dir object builds, colored logs - Handy targets for dev/clean/rebuild and `.clangd` support - **Reproducible Dev Env**: `flake.nix` adds Nix flake support (clang, norminette, formatter, etc.) for one-command onboarding. 🧊 --- ## 🤖 Continuous Integration - **GitHub Actions**: - `c-cpp.yml` — builds on push/PR - `norminette.yml` — style checks to keep 42-compliant - Automatic gates so broken builds and non-conforming code don’t land. 🧪 --- ## 🧹 Cleanup & Refactors - **Redundant libft bits removed** (now provided internally by `ft_printf` utils): - `ft_strdup.c`, `ft_strlcpy.c`, `ft_strlen.c` - **README refresh**: trimmed outdated content; clearer scope and usage. --- ## 🧨 Breaking Changes - Projects previously including `libft`’s removed functions must now rely on the local utils bundled with `ft_printf` (or provide their own). - Include path is now **`includes/`**; verify your compiler flags (`-Iincludes`). --- ## 🧰 Usage Quickstart ```c #include "ft_printf.h" int main(void) { int n = ft_printf("Hello %s, number: %d, hex: 0x%x, ptr: %p\n", "world", 42, 42, (void*)&n); ft_printf("Printed %d bytes above.\n", n); return 0; }

This project is pretty straightforward, you have to recode printf. You will learn what is and how to implement variadic functions. Once you validate it, you will reuse this function in your future projects.
