This project is about recreating the C library function printf. The function printf sends formatted output to stdout (standard output stream) by formatting the argument(s) passed in and converting the arguments(s) into a character string. This version will be used as _printf.

Our printf has been tested on Ubuntu 14.05.5 LTS

Tests done in VirtualBox on Ubuntu via Vagrant(1.9.1)

Once cloned over, the repository will contain the following files:

Format tags implemented in _printf

There are two ways to use the _printf function in your code. First step is to clone the repository into your directory

$ git clone https://github.com/kjowong/printf.git

Once that is done, you can create a static library or use the -I in gcc

Change your directory into the _printf directory in order to create your static library

$ cd printf

Compile all the .c files in _printf

gcc -Wall -Werror -Wextra -pedantic -c *.c

All your .c files should also have a corresponding .o file. Run the following to create your static library:

ar -rc lib<LIBRARY-NAME>.a *.o

To run your static library with your own YOUR-FILE.c file, use the following command:

gcc <YOUR-FILE>.c -L. -lib<LIBRARY-NAME> -o <OUT-NAME>

Make sure the _printf directory is in the same directory as your YOUR-FILE.c file and then run the following command:

gcc -Wall -Werror -Wextra -pedantic -I $PWD/printf prinft/*.c <YOUR-FILE>.c

The -I flag allows you to include the directory of the header file holberton.h. $PWD/printf takes the absolute path of the _print directory while printf/*.c compiles all your .c files in _printf

Please see the following example when _printf is implemented in your code:

#include <holberton.h>

int main(void)
{
  _printf("Let's try to print a %s sentence.\n", "simple");
  return (0):
 }

This is an an example output:

$ Let's try to print a simple sentence.

This _printf function currently does not support special flags [+ , - , `, \0 , #], field, width or precision.

There are no known bugs at the time.
