subjlog1707-pmb

Log messages to memory with a subject.

This module logs to memory.

If you want to log to your default console with a topic, use the similarly-named module with a "c" (for "console") in its name, subjclog2607-pmb.

Usage

from test.usage.js:

var makeLogger = require('subjlog1707-pmb'), someObj = /some regexp/ig,
  myLogger = makeLogger(someObj), cb, ar;

equal(myLogger.subj, someObj);
myLogger('A logger for', 'some object:', String(myLogger));

cb = myLogger.l8r('.l8r(non-array) prepares a callback');
cb('that logs exactly', 'its original arguments', 'and ignores these.');

cb = myLogger.l8r([ '.l8r(array)', 'also logs' ]);
ar = [ 'the', 'callback', 'args' ];
ar.forEach(cb);

console.log = makeLogger('fake console');
myLogger.cfg({ verbose: true });
myLogger('Verbose mode on!');
myLogger.cfg({ verbose: false });
myLogger('… and off again.');

equal.lists(myLogger(), [
  [ 'A logger for', 'some object:', '[logger for /some regexp/gi]' ],
  '.l8r(non-array) prepares a callback',
  [ '.l8r(array)', 'also logs', 'the',      0, ar ],
  [ '.l8r(array)', 'also logs', 'callback', 1, ar ],
  [ '.l8r(array)', 'also logs', 'args',     2, ar ],
  'Verbose mode on!', '… and off again.',
]);

equal.lists(console.log(), [
  [ '/some regexp/gi:', 'Verbose mode on!' ],
]);
