About slog

slog is a simple logger. It is mainly created for simplicity of use. slog doesn't use any platform dependent code. It only uses the C standard library (libc).

Build instructions

To include and build it in your cmake project, then simply add this repo and then from your project's main CMakeLists.txt file, simply add this repo as a subdirectory using add_subdirectory function in cmake. If you are not using cmake, then simply add the slog/slog.h && slog/slog.c file in your project and you are done!

Features of slog

The features are :-

• Can print coloured text
• Has various severities
• Each severity has a color associated with it by default
• If needed a custom color, change the logger's color manually, then while logging, use the severity SLOG_SEVERITY_CUSTOM.

Usage samples

Creating and deleting the logger :-

#include <slog/slog.h>

int main() {
    SLogger logger = {0};
    slogLoggerReset(&logger);
    slogLoggerSetName(&logger, "logger"); // Setting the name of the logger. It is mandatory to set a name before
                                          // Using the logger.
    
    ... // Using the logger to log stuff

    slogLoggerReset(&logger);
    return 0;
}

Using the default severities :-

slogLogConsole(&logger, SLOG_SEVERITY_INFO, "Hello!! My age :- %d, my name :- %s", 34, "CloudCodingSpace");
slogLogConsole(&logger, SLOG_SEVERITY_WARN, "Hello!! My age :- %d, my name :- %s", 34, "CloudCodingSpace");
slogLogConsole(&logger, SLOG_SEVERITY_DEBUG, "Hello!! My age :- %d, my name :- %s", 34, "CloudCodingSpace");
slogLogConsole(&logger, SLOG_SEVERITY_FATAL, "Hello!! My age :- %d, my name :- %s", 34, "CloudCodingSpace");
slogLogConsole(&logger, SLOG_SEVERITY_ERROR, "Hello!! My age :- %d, my name :- %s", 34, "CloudCodingSpace");

Using custom severity :-

slogLoggerSetColor(&logger, SLCOLOR_RED); // Can change color
slogLogConsole(&logger, SLOG_SEVERITY_CUSTOM, "Hello!!");
slogLoggerSetColor(&logger, SLCOLOR_DEFAULT); // Make sure to change the color back to default!

TODO

• Allow custom patterns for the log
• Log time along with the message
• Allow output of log patterns to a custom char* through a custom user callback.
