asynclog

A small, fast, colorful, asynchronous, type-safe C++ logging library. Uses libuv.

Example output:

Go ahead and copy files from this repo. Then include log.h somewhere in your project, for example:

#include "al/log.h"

Initialize. The logger will be automatically uninitialized at the end of the scope, when raii is destructed.

al::Scoped_Log_Init raii;

Unconditional logging:

Each message includes time and severity, with an added color. Check log.cpp to change the escape codes used for each severity.

Prints "Hello, World" as an error

al::log_e("Hello, World!");

Prints the warning Player at (5.0, 12.0, 1.0)

glm::vec3 pos(5.0f, 12.0f, 1.0f);
al::log_w("Player at (%, %, %)", pos.x, pos.y, pos.z);

Prints "Hello, World" as debug information

al::log_d("%, %", "Hello", "World");

Anything that supports to_string works in the % replacement!

Conditional logging:

These messages can be turned off by defining AL_DISABLE_LOGGING before including log.h.

Logs "Hello, Luke" as "information".

// Log a conditional information message the same way, C strings work too!
const char *const player_name = "Luke";
AL_LOG_I("Hello, %", player_name);

Translation:

Load in a mapping from semantic strings to strings in a language

#include "al/translate.h"

al::Lang lang;
lang.dict.push_back({"greeting", "Nice to meet you, %!"});

al::set_lang(lang);

Build the actual message using replacement featured earlier:

std::string message = al::t("greeting", "Luke");

Or if you want to be more explicit:

std::string message = al::translate("greeting", "Luke");

No matter which you chose, message now equals "Nice to meet you, Luke".
