Introduction

At 42_Network schools - Including 1337-, students are not allowed to use library functions. so we re-write our own functions, and printf is one of must have functions, so we write our own.

Subject

How To Use

  1. clone this repo.
  2. run the make command.
  3. include the header files.
  4. call by ft_printf, and use just as you gonna use the normal printf. ps : this project is only tested in MAC os, I don't know it's behavios in other os.

What ft_printf supports:

  • the conversions : c, s, p, d, i, o, u, x, X, f, e.
  • the size modifiares : l, ll, L, h, hh.
  • Manages : %% (with the width and all the other flags.)
  • the flags : #, 0, -, +, space, *, $ and '.
  • the minimum field-width
  • the precision.
  • the color and bold colors, even if this isn't suppoted by origin printf.

Available Colores

red, yellow, green, blue, cyan, magenta,

bold red, bold yellow, bold green. bold blue, bold cyan, bold magenta,

Notes

  • the float is implemented using the Dragon4 algorithm, we have some prety fast results.
    • printing LDBL_MAX in 0.04s
    • printing LDBL_MIN in 0.08s

for resource of how doing it your self or how it works: check ryanjuckett website (http://www.ryanjuckett.com/), and the docs folder i've attached.

  • the $ flag is not done yet, still segfaults sometimes.

  • you can use the colores this way :

    ft_printf("happy {cyan}%s{eoc} year {red}%d{eoc}", "new", 2020);
