python实现对svn操作及信息获取
目录
一、实现效果
二、完整代码
三、结果展示、代码解析
1、上述代码最终会有两个输出展示
2、代码解析
一、实现效果1、通过python获取路径下所有文件的svn状态
2、通过python对svn进行“提交、删除、锁、解锁、删除等操作”
3、通过svn打开小乌龟界面

三、结果展示、代码解析
1、上述代码最终会有两个输出展示
a、打开小乌龟提交界面
这里对应的其实就是 “TortoiseProc.exe /command:commit /path %s” % pathsStr" 这句命令行的运行
b、展示SVN 文件状态
我们需要查看上述 “svn状态对照表”，可以发现状态码 “2、4、16” 分别对应的就是 “本地锁定、本地有修改、未提交到库”，并且到文件夹中查看可知是一一对应的
2、代码解析首先，我们看 “_doSvnCommandSync” 该函数的实质就是运行命令行
我们将svn的各种命令行传入上述函数 “_doSvnCommandSync”，以此构造了python内的 "提交、删除、锁、解锁 等函数"
比较特殊的是 “_svnStatusXMLSync” 这个获取svn状态的函数，因为我们是将其以xml的格式输出，因此要对其结构进行解析，“svn status " + path + " -u --xml” 这条指令能够获取 path路径下所有文件的svn状态，我们在 “syncGetAllFileStatus” 函数中对其解析便可以得到我们想要的信息，包括 锁的相关信息、提交信息、文件状态等
以上就是python实现对svn操作及信息获取的详细内容，更多关于python操作svn信息获取的资料请关注软件开发网其它相关文章！
