Ft_printf - recreating printf functionality ⚙️

Because I'm bored of ft_putstr 😎 Actually, no. I was just not allowed to use printf in my school projects, so I recoded my own. This project covers implementation of a C laguage feature – variadic functions. It also includes practice detailed management of the printing options via dispatch tables (which I unfortunately did not implement in this project when I was a beginner - I know, shame on me 😳).

Ft_printf argument prototype & features I handle:

Argument prototype: %[flags][width/margin][.precision][hh|h|l|ll|j|z]type, where:

• flags: + || - || || # || 0;
• width/margin:
  • min amount of displayed digits, does not cut digits if less, fill with spaces on the left side;
  • if * added it's necessary to pass one more parameter with a number of spaces before the actual parameter;
• .precision:
  • for diouxX min amount of digits, fill with 0 is necessary;
  • for eEf amount of digits after dot;
  • for gG amount of all digits, if bigger displays number;
  • for sS max amount of characters;
  • if * added is necessary to pass one more parameter with a number of spaces before the actual parameter;
• [hh|h|l|ll|j|z|q]: default values' modification:
  • hh: for idouxX - char;
  • h: for idouxX - short int;
  • l: for idouxX - long int, for feE - double;
  • ll: for idouxX - long long int;
  • j: for idouxX - intmax_t;
  • z: for idouxX - size_t;
  • q: for CS - prints Unicode
    
    

How to run ft_printf?

Copy and paste to your terminal following text:

git clone https://github.com/psprawka/Ft_printf.git 42SV_ft_printf
cd 42SV_ft_printf
make

This will create a static library - libftprintf.a - which you just need to include to the project that you need ft_printf in. 🔧
