A light-weight logging library for C++, Java, and C# supporting custom log formats, colored output, and column padding for alignment.

This is a library I've been working on with versions for C++, java & C# where you make custom formats and Log based on them, for example you could make an ERROR Like this: [ERROR] [date, time-stamp, time-zone] (file:thread-ID:line)

but you would write it like this: // define the master format

master_style = "%C[%N]%c%S%G[%D %T %Z]%c %M %G(%F:%t:%L)";

// tell the logger what colour to use for a given name

logger.add_format("ERROR", master_style, Colour::RED);

so now the [ERROR] part will be red,
the time area will be grey,
and the location grey,
but you could really make any style you wanted.
And once you have a master format you could also add different types of logs: logger.add_format("SUCCESS", style_minimal, Colour::GREEN);
logger.add_format("INFO", master_style, Colour::CYAN);
logger.add_format("WARN", master_style, Colour::YELLOW);

also the %S we put in there is actualy a colum padder so you logs will be inline: [INFO] [16/06/2026 10:58:00 AUS Eastern Standard Time] Initializing core subsystem components. (src/main.cpp:1:39)
