Revised Libft

RevisedLibft is an enhanced version of my own implementation of libft project of @Hive Helsinki, providing additional utilities for string manipulation, memory management, linked lists, and more. This project reorganizes and expands the original libft, making it modular, easier to maintain and add complicated ft_printf and get_next_line implementations.

Features

• Character Functions: ft_isalpha, ft_isdigit, ft_tolower, etc.
• String Manipulation: ft_strlen, ft_strjoin, ft_strtrim, etc.
• Memory Functions: ft_memcpy, ft_memset, ft_calloc, etc.
• Linked List Functions: Bonus implementation for handling linked lists.
• Printf and Output: Custom implementation of ft_printf and various output functions.
• Modular Design: Functions are split into different categories like ctype, memory, string, and more for clarity.

Installation

To integrate RevisedLibft into your project, follow these steps:

1. Clone the repository:

   git clone https://github.com/NikolasGoulios/RevisedLibft.git

2. Navigate to the project directory:

   cd RevisedLibft

3. Compile the library:

   make

4. You can also clean up the object files and recompile using:

   make clean
   make re

Usage

Once compiled, the library file libft.a can be included in your own C projects by linking it during compilation:

gcc -L. -lft your_file.c -o your_program
