dbug

A drop-in replacement for debug, for slightly more utility.

var dbug = require('dbug')('foo:bar');

dbug('just like debug'); // except goes to stdout, not stderr
dbug(new Error('also like debug'));

// additional methods
dbug.info('info');
dbug.warn('warning');
dbug.error('red alert');

Just like debug, dbug won't do anything unless the DEBUG env variable matches the dbug logger, but with slightly more lenient matching.

DEBUG=*
DEBUG=foo,quux
DEBUG=foo // also acts as foo:*

A user script wanting to dynamically enable or disable can do it a couple ways:

require('dbug').env = 'foo,quux'; // just like ENV var
var foo = require('dbug')('foo');
foo.enabled = true;
