gaze: nodejs 下监控文件改变( gaze: another file watcher in nodejs)

refer to:  https://github.com/shama/gaze

tishadow 使用了gaze 来监控文件的改动.

翻看了下文档, gaze 的使用很简单 直观:

var gaze = require('gaze');

// Watch all .js files/dirs in process.cwd()
gaze('**/*.js', function(err, watcher) {
  // Files have all started watching
  // watcher === this

  // Get all watched files
  this.watched(function(err, watched) {
    console.log(watched);
  });

  // On file changed
  this.on('changed', function(filepath) {
    console.log(filepath + ' was changed');
  });

  // On file added
  this.on('added', function(filepath) {
    console.log(filepath + ' was added');
  });

  // On file deleted
  this.on('deleted', function(filepath) {
    console.log(filepath + ' was deleted');
  });

  // On changed/added/deleted
  this.on('all', function(event, filepath) {
    console.log(filepath + ' was ' + event);
  });

  // Get watched files with relative paths
  this.relative(function(err, files) {
    console.log(files);
  });
});

// Also accepts an array of patterns
gaze(['stylesheets/*.css', 'images/**/*.png'], function() {
  // Add more patterns later to be watched
  this.add(['js/*.js']);
});
