FortyTwo Library

Empower your 42 school projects with the FortyTwo Library!

Function Categories

The FortyTwo Library provides functions in two main categories:

Essential C Functions: Reimagined and improved versions of standard C library functions, with added error handling and enhanced robustness.
Helper Functions: A collection of utilities designed to simplify common tasks and streamline your development workflow.

Function Table

Character	Integer	Memory	Output	String
`ft_isalnum`	`ft_atoi`	`ft_bzero`	`ft_putchar_fd`	`ft_split`
`ft_isalpha`	`ft_itoa`	`ft_calloc`	`ft_putendl_fd`	`ft_strchr`
`ft_isascii`		`ft_memchr`	`ft_putnbr_fd`	`ft_strdup`
`ft_isdigit`		`ft_memcmp`	`ft_putstr_fd`	`ft_striteri`
`ft_isprint`		`ft_memcpy`		`ft_strjoin`
`ft_tolower`		`ft_memmove`		`ft_strlcat`
`ft_toupper`		`ft_memset`		`ft_strlcpy`
				`ft_strlen`
				`ft_strmapi`
				`ft_strncmp`
				`ft_strnstr`
				`ft_strrchr`
				`ft_strtrim`
				`ft_substr`

For detailed descriptions and usage examples, please refer to the 42 libft subject documentation.

Usage

Prerequisites:

A C compiler (e.g., gcc, clang)
Meson build system

Build Instructions:

Configure Build:
```
meson setup build
```
Compile:
```
meson compile -C build
```

Important Note for 42 Students:

Installing the library is NOT recommended as it may conflict with the requirements of 42 projects, which often need to run without external library dependencies. Instead, you can directly link the library to your projects.

Linking:

To use the FortyTwo Library in your project, add the following flags to your C compiler command:

gcc main.c -Lbuild/ -lft

-Lbuild/: This flag tells the compiler to look for the library in the build directory (adjust the path if necessary).
-lft: This flag specifies the library to link against (in this case, the FortyTwo library, named libft).

Example

Here's a simple example using the ft_strlen function from the FortyTwo Library:

#include "forty_two.h" // Include the library header 
#include <stdio.h>

int main() {
    char *str = "Hello, 42!";
    int length = ft_strlen(str);

    printf("The length of the string is: %d\n", length); 
    return 0;
}

Testing

We utilize the excellent libftTester project developed by Tripouille for rigorous testing of our library. A big thank you to Tripouille for creating this valuable resource for the 42 community!

You can find the libftTester project on GitHub: https://github.com/Tripouille/libftTester

Important Note: The libftTester is a separate project and is not included with this library. You'll need to download and set it up according to its instructions.
