Libft

My personnal lib. At first, this used to contain every mendatory functions for the libft 42 project.
Then, i started to extend it more and more, adding functions when i needed it or simply by curiosity or for personnal learning purpose.

This lib is divided into several "submodules" to simplify it developpment. The makefiles allow a great and easy expansion trough quick new submodule addition.

Modules :

• ftio

  This module contains all the I/O functions like ft_printf or ft_readline.

• ftlib

  Contains the string processing and memory managment functions.

• ftmath

  Multiple math functions, already in the standard libmath, but have the advantage to be instructive and allowed by 42, whatever the project.

• ftregex

  (WIP) Trying to implement my own regular expression engine.

• ftcipher

  Cryptographic module. (Only contains a single ciphering/deciphering homemade function for now)

Compilation :

The only Makefile you'll have to run is the default one Makefile at repository root.
Without any argument, it should compile a statical version libft.a of the library. A shared version libft.so can be compiled trough the make libft.so or make so command

Dependancies :

To compile the lib, the makefile need those commands to be available.
rm cp ln ar gcc bc tr sed awk cut sort echo mkdir which printf ranlib et sh.

if one of the rm cp ln ar mkdir or gcc commands is unavailable, the makefile won't be able to compile at all and throw an error.

However, you can change their default values trough the variables.mk file at the repository root, or by defining the associated variables (RM CP LN CC AR and MKDIR) trough the command line :
make CC=clang AR='libtool -static -o'

The default values for those variables are:
  RM    = rm -rf
  CP    = cp -rf
  LN    = ln -s
  AR    = ar -rc
  CC    = gcc
  MKDIR = mkdir -p

All the other commands aren't used to compile the library, but are mendatory to enable the makefile's fancy mode, which is the custom output for compilation process (showed in the upper gif). So if one of those commands is missing, the fancy mode is automatically disabeled.

Note that you can force disable the fancy mode by passing FANCY_MODE=FALSE to the command line:
make FANCY_MODE=FALSE

I'm trying my best not to rely on other libs, but for now, the libft still depends on any other C standard library like the glibc.
However, i try as much as i can to stick to C89 (ansi) and not to use any extension (pedantic).
Actually, the only exceptions to this are the ft_printf function and it's variants (mostly because of the long long) and a tiny part of ftmath....

Norm :

Of course, the whole library sources are 42 norm valid (version 2.0.2)
