printf_vector

like libc printf, but can use vector input.

modify from eyalroz/printf to support vector

• for cpp
• header only
• use std::snprintf
• add namespace
• add vector support

Usage

the example code is in main.cpp

printf_vector::vector_input input;
input.add(1);
input.add(2.2f);
input.add("333");
input.add((void *) 0x4);
input.add(2);
input.add("55555");
input.add(5);
input.add(6);
input.add(1.12345);

const char *fmt = "Hello, World! int=%d float=%f string=%s pointer=%p short-string=%.*s width-int=%*d short-float=%.2f\n";
printf_vector::printfv(fmt, &input);

and the output is

Hello, World! int=1 float=2.200000 string=333 pointer=0000000000000004 short-string=55 width-int=    6 short-float=1.12
