统计svn上两个版本或一段时间内的代码修改行数


http://blog.csdn.net/skygpan/article/details/47749891

有的时候，我们想要统计svn上两个版本或一段时间内的代码修改行数。我们可以通过svn提供的svn diff命令帮助我们解决这个问题。

svn环境

首先，你必须要有一个svn的环境。如果你安装的是TortoiseSVN客户端，那么一定要安装command line client tools。这个就是svn最基本的命令行工具。

比较文件

通过如下命令比较文件差异并输出到文件

svn diff -r 13605:13762 https://192.168.1.1/xxx --username xxx --password xxx > c:/temp_svn_file

分析文件

打开文件，可以看到如下几种类型：

1. 含有1个+或-开头的行

2. 含有3个+或-开头的行

3. 不含有+和-开头的行
其中：1个+和-说明对文件的增加，修改和删除操作。我们只要知道这个，就可以统计修改的代码行数了。
其他符号说明
我们只要统计以+开头的行，就可以知道修改代码的总行数了，为了统计有效修改行数，我们还要剔除掉以+开头并且后面没有内容的空行。

实现

java实现

<code class="language-java hljs  has-numbering"><span style="font-size:14px;">BufferedReader r = <span class="hljs-keyword">new</span> BufferedReader(<span class="hljs-keyword">new</span> FileReader(<span class="hljs-keyword">new</span> File(<span class="hljs-keyword">this</span>.tempFile)));
<span class="hljs-keyword">while</span> ((line = r.readLine()) != <span class="hljs-keyword">null</span>) {
<span class="hljs-keyword">if</span> (line.startsWith(<span class="hljs-string">"+"</span>) && !line.startsWith(<span class="hljs-string">"+++"</span>) && !isBlank(line.substring(<span class="hljs-number">1</span>))) {
count++;
}
}
r.close();</span></code>

顺便说下，statsvn中内置了该功能
