Singleton for simple logging

Basic Usage

import singlog;

void main(string[] argv) {
    log.output(log.SYSLOG | log.STDOUT | log.FILE)  // write to syslog, standard output stream and file
        .program(argv[0])                           // program name as an identifier (for Windows OS)
        .level(log.DEBUGGING)                       // logging level
        .color(true)                                // color text output
        .file("./test.log");                        // the path to the log file

    log.i("This is an information message");
    log.n("This is a notice message");
    log.w("This is a warning message");
    log.e("This is an error message");
    log.c("This is a critical message");
    log.a("This is an alert message");
    log.d("This is a debug message");
}

Examples

Setting the name of the logged program (it matters for Windows OS):

log.program("My program");

Color output setting (false by default):

log.color(true);

Setting the error output level:

log.level(log.DEBUGGING);
log.level(log.ALERT);
log.level(log.CRITICAL);
log.level(log.ERROR);
log.level(log.WARNING);
log.level(log.NOTICE);
log.level(log.INFORMATION);

Assigning a target output:

log.output(log.SYSLOG);
log.output(log.STDOUT);

Setup and allowing writing to a file:

log.output(log.FILE);
log.file("./file.log");

Output of messages to the log:

log.a("Alert message")          =>    log.alert("Alert message");
log.c("Critical message")       =>    log.critical("Critical message");
log.e("Error message")          =>    log.error("Error message");
log.w("Warning message")        =>    log.warning("Warning message");
log.n("Notice message")         =>    log.notice("Notice message");
log.i("Information message")    =>    log.information("Information message");
log.d("Debugging message")      =>    log.debugging("Debugging message");
