Github恶搞之自定义你的contribution图表
在正式写程序之前让我先来看看效果：
对了，这个程序的效果就是生成一个具有你想要的“contributions in the last year”图表的html页面。
当然，html文件，而不是你在Github上面个人主页中的实际的页面。
当然，你可以通过个人努力达到效果（我之前就见过一个I 心 U，但是暂时没有找到出处），不过那需要非常努力和耐性，并且那么做的话收获更多（如果不是仅仅为了那么做而commit+push的话），所以这里介绍一个程序来实现这种方法。
接下来我将用Java来编写程序，主要分为两个步骤：
- 下载网页源代码
- 根据自己设计的字体替换网页中对应的内容
其中第二步有很多现有的工具，比如Jsoup，但是可以用正则表达式直接解决，后来我发现一个写起来比较方便的方法，因为我发现每一种颜色对应一个fill元素，所以可以直接从fill元素下手。
我把设计的字体保存在了文件picture-fonts.txt（是一个只有字符"0"和"1"的字符文件）中，并把每个字符在picture-fonts.txt中的位置保存在了position.txt中。
他们的预期效果如下：
这意味着在这里你暂时只能达到“ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789”的效果。
“contributions in the last year”列表里面一共有7行53列，为了保（tou）险（lan）这里就先不去动最后一列了。所以我们有7行52列可以用，所以这个程序将会输出最多的我们想要的结果。
程序的代码就一个，内容如下：

另外还有2个资源文件，Github项目位置：https://github.com/moonlightpoet/FunGithub 有兴趣可以玩一下。
另外github pages上面放了两个可以看看在线效果（一个I Love you的和一个Fxxk you的）：
注：今天找到了知乎上问题的出处了
