living comfortably without anybody's help.

Grunt is very popular nowadays. Although it is fun to use, its configuration is really annoying. If you haven't used it before and want to be proficient in it all at once, there is a certain learning cost, and you also have to install the big guy node. At the beginning of the project, we chose the lightweight tool compiler.jar for packaging. I have been thinking about how to write a one-click packaging tool. Previously, we manually spliced ​​some js files into a batch file that met the requirements of the compiler.jar packaging file, and then ran this batch to generate the js and css files we needed. As the number of js files increases, manually splicing the addresses of these files becomes very difficult, and it is easy to miss or duplicate certain files, so the writing of the "one-click packaging tool" becomes urgent. .

There are still a lot of bugs to come. A living person cannot be choked to death by urinating. There are always more solutions than problems. I know a little bit of PHP. PHP is very good at processing files. It's time to let it play a role. So I thought of using PHP to automatically extract the js and css in the index, then generate a batch file in the specified format, run the batch silently in the background, and finally return the results to the monitor. This way I can sit back and enjoy the results. Thinking about it makes me a little excited, so I simply wrote an interface.

The next step is to implement the function. Don’t rush to write the code first, analyze the requirements:

1. Traverse the index.html file and extract js files or css files.

2. Filter this file, because some are commented out and some are used for debugging.

3. Generate the corresponding batch file

4. Execute batch file

5. Display processing results

Since there are two situations, I will use a factory mode to adapt it to facilitate the expansion of other types in the future. I need to take a longer-term view. Now that we have the factory, we simply add another interface. It is agreed that the two interfaces of "receiving requests" and "output results" must be implemented. Think about it again, both js and css may have the same functions. Let them inherit a parent class to reuse code, so inheritance is also used first. The current design should meet my requirements, so I started writing php code.

The rough skeleton comes out. The specific coding process is relatively simple. The slightly more difficult method is to perform batch processing.

This is a method provided online, you may need it in the future, so I post it here:

<span>public</span> <span>function</span> runBat(<span>$name</span><span>){
        </span><span>if</span>(!<span>file_exists</span>(<span>$name</span>) || !<span>$this</span>-><span>isAuto){
            </span><span>return</span><span>;
        }
        </span><span>//</span><span>转入后台处理</span>
        @<span>exec</span>(<span>pclose</span>(<span>popen</span>("start /B ". <span>escapeshellcmd</span>(<span>$name</span>), "r"<span>)));
    }</span>

In the previous index.html, there is a name="noBuild" that I added artificially. This is because I want to filter js files with this logo. In this way, if I want to filter other files in the future, I only need to add this logo. That’s it, no need to change the php code. Since it is for internal use, there is no form item to specify the path of the project. By default, the upper-level directory where index.html is located is the project directory. This design simplifies operation and improves efficiency.

Regarding traversing specific files, I recommend the glob function, a very simple solution:

<span>$files</span> = <span>glob</span>(<span>$path</span>.'/*.css',GLOB_NOSORT);

The following is the project directory structure diagram:

Another operation rendering:

The last is the processing result picture:

Finally, I no longer have to write grunt configuration and install node. I no longer have to worry about pulling down a bunch of node stuff from svn when updating. It’s time to say goodbye to them:

It seems I forgot to show the front-end code:

<span>/*</span><span>*
 * 选项卡类
 * @param {string} id 选项卡的ID
 </span><span>*/</span>
<span>function</span><span> Tabs(id){
    </span><span>var</span> node = document.querySelector('#'+<span>id);
    </span><span>var</span> selected = node.querySelector('.selected'<span>);
    </span><span>this</span>.selected =<span> selected;
    </span><span>this</span>.node =<span> node;
    </span><span>this</span><span>.bindEvent();
}

</span><span>/*</span><span>*
 * 切换选项卡
 * @param  {object} event 事件
 * @return {[type]}   [description]
 </span><span>*/</span><span>
Tabs.prototype.change </span>= <span>function</span><span>(event){
    </span><span>var</span> element =<span> event.target;
    </span><span>if</span>(element.tagName.toLowerCase()=='li'<span>){
        </span><span>if</span>(element.className=='selected'<span>){
            </span><span>return</span><span>;
        }
    }</span><span>else</span><span>{
        </span><span>while</span>(element != <span>this</span><span>.node){
            element </span>=<span> element.parentNode;
            </span><span>if</span>(element.tagName.toLowerCase()=='li'<span>){
                </span><span>break</span><span>;
            }
        }
        </span><span>if</span>(element == <span>this</span>.node) <span>return</span><span>;
    }
    </span><span>this</span>.selected.removeAttribute('class'<span>);
    element.className </span>= 'selected'<span>;
    </span><span>this</span>.selected =<span> element;
    </span><span>this</span><span>.content();
}

Tabs.prototype.content </span>= <span>function</span><span>(){
  </span><span>var</span> form =<span> document.form1;

    </span><span>switch</span>(<span>this</span><span>.getTabType()){
      </span><span>case</span> 'js'<span>:
        form.style.display </span>= 'block'<span>;
        form.children[</span>0].innerHTML = '自动压缩JS'<span>;
        </span><span>break</span><span>;
      </span><span>case</span> 'css'<span>:
        form.style.display </span>= 'block'<span>;
        form.children[</span>0].innerHTML = '自动压缩CSS'<span>;
        </span><span>break</span><span>;
      </span><span>default</span><span>:
    }
}</span>

I know both front-end and back-end, so I am so willful. Just one click and say goodbye to worries! Make your own tools and let others do the hard work, so easy!

The above is an introduction to how to do it yourself and have enough food and clothing. It includes all aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
