Description

goinglogging is an open source, lightweight, multiplatform, single header C++11 library that logs information to command line or file. This is useful when debugging realtime systems where compiling with debug symbols and/or a low optimization level will slow down the program too much. This library is designed to make it as effortless as possible to output the name and value of a variable.

Note that goinglogging is a logging library for debugging when a debugger is a worse alternative. It is not for heavy logging. Use a proper library for that.

Status

goinglogging is currently in development. It means that the API is subject to change and that bugs galore. Just so you know :)

Usage

#include "goinglogging.h"

A variable

int i = 1;
l(i);

Which outputs:

i = 1

Multiple variables

int i = 1;
const char* s = "s";
l(i, s);

Which outputs:

i = 1, s = "s"

Array

int a[] = {0, 1, 2};
l_arr(a, 3);

Matrix

int m[][] = {{0, 11}, {22, 33}};
l_mat(m, 2, 2);

Custom objects

Can output any object with an overloaded << operator.

Prefixes

Output file, line, and other information by using:

gl::set_prefixes(gl::prefix::FILE | gl::prefix::LINE);
int i = 1;
l(i);

Which outputs:

my_file.cpp:68: i = 1

Disable output

gl::set_output_enabled(false);

Enable colored (red) output

gl::set_color_enabled(true);

External dependencies

goinglogging only depends on the C++ standard library.
