simple.config('myLogArgColor', 'underline');
// set context and print log
simple.name('myLog').log('my custom log');

var simple = require('node-simple-log');

simple.log('Some', 'log');

function Foo() {
    simple.log('Some', 'log', 'in', 'constructor');
}
Foo.prototype.bar = function() {
    simple.log('Some', 'log', 'in', 'Foo.bar()');
}

function Bar() {
    simple.log('Some', 'log', 'in', 'Bar()');
}

var obj = new Foo();
obj.bar();

Bar();

Result:

[2012-09-30 15:53:44] [-] Some log
[2012-09-30 15:53:44] [new Foo] Some log in constructor
[2012-09-30 15:53:44] [Foo] Some log in Foo.bar()
[2012-09-30 15:53:44] [Bar] Some log in Bar()
