42 Silicon Valley recreation of printf.
These functions are now submodules of my 42 library, so I would suggest grabbing that if you want to use them.
The floats are bad approximations that will only work for a small range of numbers; see the note in pf_floats.c on why, and for resources.
Has typedefs for printf, sprintf, snprintf, asprintf, dprintf, vprintf, vsprintf, vsnprintf, vasprintf, and vdprintf, with prefix ft_ (i.e. ft_printf(const char *format, ...)).
Covers dDioOuUxXfFcCsSp% conversions, with hh h l ll j z length modifiers and #0 -+. flags. See the printf man page for more details on what each of those do.
Contains additional modifier %b or %B for binary, flag %_<base>d for bases [2, 16] (%_^<base>d for uppercase, works with any of dDioOuUxX) (ex ft_printf("%_^12o", 11) returns B), and colour printing.
Colour printing is set via %{<colour name>} to change the text to one of the eight standard ANSI colours (red, green, blue, yellow, magenta, cyan, black, and white) and %[<colour name>] for background colour; %#{<cn>} or %#[<cn>] for bold; and %{} or %[] for end of colour.
Similarly, wide characters or strings can be printed with UTF-8 encoding for things like emojis in the terminal, with %#lc or %#C for wide chars and %#ls or %#S for strings.
