Grunt之添加文件監視：Grunt-watch (已備份)

今天又完善了一下Grunt的Task，增長了JSHint和Watch功能，再修改了每一個NodeJs代碼以後，會運行JSHint對代碼進行檢查。修改了LESS文件以後，會重現編譯LESS爲CSS代碼：

"use restrict";

var _ = require('underscore')
  , path = require('path')
  , fs = require('fs');


var scriptFiles = _.chain({
    self: ['*.js'],
    test: ['../Test/*.js', '../Test/test/*.js', '../Test/FakedWebService/*.js', '../Test/FakedWebService/*/*.js'],
    webSite: ['../WebSite/*.js', '../WebSite/*/*.js'],
    webService: ['../WebService/*.js', '../WebService/*/*.js']
}).values().flatten().value();

var lessFilePairs = [
    { "../WebSite/public/css/site.css": "../WebSite/public/less/site.less" },
    { "../WebSite/public/css/page_send_report.css": "../WebSite/public/less/page_send_report.less" },
    { "../WebSite/public/css/page_data_mining.css": "../WebSite/public/less/page_data_mining.less" },
    { "../WebSite/public/css/page_bucket_table.css": "../WebSite/public/less/page_bucket_table.less" }
];

在研究JSHint的時候，發現，原來還有個JSLint，JSHint是基於JSLint的並作了改進。

另外，使用Should庫的時候，JSHint會報錯，他認爲should庫使用表達式做爲語句運行時不規範的，例如 something.should.be.ok；我也看到了TJ大神與某我的的辯論，TJ認爲，shouldJs庫是可愛的，並且Unit Test框架應該可愛些，TJ是不會妥協的：https://github.com/visionmedia/should.js/issues/9，解決方法很簡單，修改JSHint的參數就能夠了。沒啥大不了的。
