Single header library with simple, thread-safe methods for printing colorized debug info to std::cout.

• prints to std::cout
• thread-safe
• prints the thread's id
• each thread a different colour

Just

#include "mt_color_print.hpp"

and do not forget to link with pthread

C++17

template<typename ... Ts>
void print(Ts && ... args)

Print args to std::cout, without being interrupted by other threads, and preceded by a (perhaps colorized) string representation of the thread's id, between brackets. Print a space between each adjacent arg.

Params:

• ...args arguments, of printable types (i.e. having an extraction to std::ostream operator overload)

#include "mt_color_print.hpp"

int x = -82;
bool b = true;

mt_color_print::print(3.14f,x,b,std::string("hello"),"hello again");

output:

[140485091915520] 3.14 -82 1 hello hello again

template<typename Iter>
void print_range(Iter from, Iter to)

Print items in the iterator range [from,to) to std::cout, without being interrupted by other threads, and preceded by a (perhaps colorized) string representation of the thread's id, between brackets. Each item on its own line.

Params:

• from iterator pointing to the first element, which must be of a printable type (i.e. having an extraction to std::ostream operator overload)
• to iterator pointing to one past the last element, which must be of a printable type (i.e. having an extraction to std::ostream operator overload)

#include "mt_color_print.hpp"

std::vector<int> v{1,2,3,4};

mt_color_print::print_range(v.cbegin(),v.cend());

output:

[140485091915520] 
1
2
3
4

void set_color_enabled(bool enable)

Enable/disable colorized output. Thread-safe, valid for every thread

Params:

• enable boolean value

bool is_color_enabled()

Tell if coloring of output is enabled.
