My very own C library.

Libft

My very first library in C, made for 42 School.

This repository contains a collection of functions that replicate some of the standard C library functions as well as introduce additional utility functions. The library is primarily intended for use within the 42 School curriculum.

Introduction

The Libft library provides a range of functions to perform various operations on strings, files, and linked lists. It serves as a foundational toolset for C programming, aiding in tasks such as memory manipulation, string processing, and data structure management. Some functions are optimized for performance, while others provide essential utilities.

Usage

Warning

During the 42 curriculum you are required to develop and use your Libft library.

From Source

Requirements:

• Clang 12
• GNU Make

Steps:

1. Clone this repository to your local machine.
2. Navigate to the repository's root directory.
3. Run make -C ./libft to compile the library.

A compiled library named libft.a will be generated. You can link this library with your C programs to access the provided functions.

Using Nix

This repository contains a Nix Flake that provides a Nix package for Libft:

You can build the library using nix build:

nix build github:vinicius507/libft#libft

Or add it to a nix develop shell:

{
  inputs = {
    nixpkgs.url = "nixpkgs";
    libft = {
      url = "github:vinicius507/libft";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };
  outputs = {
    self,
    nixpkgs,
    libft,
  }: let
    system = "x86_64-linux";
    pkgs = import nixpkgs {
      inherit system;
      overlays = [
        libft.overlays.libft
        libft.overlays.devshell # Overrides the stdenv from mkShell to use clang 12
        self.overlays.ft_malcolm
      ];
    };
  in {
    devShells.${system}.default = pkgs.mkShell {
      # Adds the libft library and header file to the shell LIBRARY_PATH and C_INCLUDE_PATH
      packages = [pkgs.libft];
    };
  };
}
