🚀 This project consists of coding basic C functions (see below), which are then compiled
into a library for use in other projects of the cursus.

Functions from <ctype.h> library

• ft_isalnum - alphanumeric character test.
• ft_isascii - test for ASCII character.
• ft_isalpha - alphabetic character test.
• ft_islower - lower-case character test.
• ft_isupper - upper-case character test.
• ft_isdigit - decimal-digit character test.
• ft_isprint - printing character test.
• ft_tolower - upper case to lower case letter conversion.
• ft_toupper - lower case to upper case letter conversion.

Functions from <stdlib.h> library

• ft_atoi - convert ASCII string to integer.
• ft_calloc - memory allocation.

Functions from <strings.h> library

• ft_bzero - write zeroes to a byte string.
• ft_memccpy - copy string until character found.
• ft_memchr - locate byte in byte string.
• ft_memcmp - compare byte string.
• ft_memcpy - copy memory area.
• ft_memmove - copy byte string.
• ft_memset - write a byte to a byte string.

Functions from <string.h> library

• ft_strlen - find length of string.
• ft_strchr - locate character in string (first occurrence).
• ft_strrchr - locate character in string (last occurence).
• ft_strstr - locate a substring in a string.
• ft_strnstr - locate a substring in a string (size-bounded).
• ft_strcmp - compare strings.
• ft_strncmp - compare strings (size-bounded).
• ft_strlcpy - size-bounded string copying.
• ft_strlcat - size-bounded string concatenation.

Non-standard functions

• ft_putchar_fd - output a character to given file.
• ft_putstr_fd - output string to given file.
• ft_putendl_fd - output string to given file with newline.
• ft_putnbr_fd - output integer to given file.
• ft_itoa - convert integer to ASCII string.
• ft_substr - extract substring from string.
• ft_strtrim - trim beginning and end of string with the specified characters.
• ft_strjoin - concatenate two strings into a new string (with malloc).
• ft_split - split string, with specified character as delimiter, into an array of strings.
• ft_strmapi - create new string from modifying string with specified function.

Linked list functions

• ft_lstnew - create new list.
• ft_lstsize - count elements of a list.
• ft_lstlast - find last element of list.
• ft_lstadd_back - add new element at end of list.
• ft_lstadd_front - add new element at beginning of list.
• ft_lstdelone - delete element from list.
• ft_lstclear - delete sequence of elements of list from a starting point.
• ft_lstiter - apply function to content of all list's elements.
• ft_lstmap - apply function to content of all list's elements into new list.

Note: functions marked with * are bonus functions (not mandatory by the project's subject).

🛠️ Usage

Requirements

The library is written in C language and thus needs the gcc compiler and some standard C libraries to run.

Instructions

1. Compiling the library

To compile the library, run:

$ cd path/to/libft && make

2. Using it in your code

To use the library functions in your code, simply include its header:

#include "libft.h"

and, when compiling your code, add the required flags:

-lft -L path/to/libft.a -I path/to/libft.h

📋 Testing

1. I haven`t coded a tester yet, but you can make your own test for each function. Here some third party testers that you can use.

Third-party testers

• xicodomingues/francinette
• jtoty/Libftest
• alelievr/libft-unit-test
• Night-squad/libft-war-machine-v2019
• t0mm4rx/libftdestructor
