bracket

Bracketing made easy. Open a bracket and take a snapshot, you may want to close it (and evaluate differences) o tap it (ongoing evaluate it) whilst it is still opened [Image needed].

You may need a handler to do your evaluations. Bracket (version 0.0.1) is provided with just a handler --but an illustrative one! The ProfilingHandler (see example below) gives you information about subs' elapsed time (both closing a bracket and tapping it).

Changelog

0.0.5

• Added setLogger to Bracket.ProfilingHandler
• Minor bugfixes

0.0.2

• Bracket.ProfilingHandler now admits an options argument making it easy to change the default configuration for brackets created using that particular handler.

Example

At this very premature stage of bracket:

var Bracket = require('./bracket');
var _console = {
  warn:  function() { console.warn.call(console,  'WARN '.concat([].slice.call(arguments))) },
  info:  function() { console.info.call(console,  'INFO '.concat([].slice.call(arguments))) },
  debug: function() { console.info.call(console, 'DEBUG '.concat([].slice.call(arguments))) }
}
var handler = new Bracket.ProfilingHandler({
  logger: _console,
  threshold: {
    warn: 50,
    info: 10
  }
});
 
var bracket = new Bracket(handler);
 
var total = 10;
var i = total;
var testName = 'Iteration test';
function test() {
  var rand = Math.round(Math.random() * 10);
  var id = 'Iterations left: ' + i;
  bracket.open(id);
  setTimeout(function() {
    bracket.tap(testName);
    bracket.close();
    if (--i) test();
    else {
      bracket.close(testName);
    }
  }, rand);
}
 
bracket.open(testName, { threshold: { warn: 200, info: 75 } });
test();

Would output something like:

DEBUG Iteration test
DEBUG Iterations left: 10
INFO (13ms) Iterations left: 10
DEBUG Iterations left: 9
DEBUG Iterations left: 8
DEBUG Iterations left: 7
DEBUG Iterations left: 6
DEBUG Iterations left: 5
DEBUG Iterations left: 4
DEBUG Iterations left: 3
INFO (10ms) Iterations left: 3
DEBUG Iterations left: 2
INFO (11ms) Iterations left: 2
DEBUG Iterations left: 1
INFO (77ms, 7.7ms/i) Iteration test

To-do

• Better documentation and examples
• Create new handlers
