如何更改的文件出口2个SVN版本

Question

我怎样才能导出SVN改变文件有两个版本有所改变之间。我需要通过命令行或使用任何脚本（具有适当的文件夹结构）的解决方案。另外，我需要基于Windows的解决方案。

例如某事像：

export {svn diff --summarize -r 50:HEAD} 

我想用文件的副本的目录树凡在任何版本上

据我所知，SVN没有提供这样的功能。但是你可以使用SharpSVN来编写一个简单的c＃程序来完成它。以下是您可以使用的示例。在此示例中，我得到了整个从版本100更改文件200

using SharpSvn; 
using System.IO; 
using System.Collections.ObjectModel; 
using Microsoft.VisualBasic; 

namespace SvnDiffExporter 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      SvnClient client = new SvnClient(); 
      SvnRevisionRange range = new SvnRevisionRange(100, 200); 
      MemoryStream result = new MemoryStream(); 

      Collection<SvnLogEventArgs> items; 
      SvnLogArgs logargs = new SvnLogArgs(range); 
      client.GetLog(@"e:\Artifacts", logargs, out items); 

      int i = 0; 
      string [] path = new string[255]; 
      foreach (SvnLogEventArgs ar in items) 
      { 
       foreach (SvnChangeItem changeitem in ar.ChangedPaths) 
       { 
        if (changeitem.Action != SvnChangeAction.Delete) 
        { 
         path[i] = changeitem.Path; 
         i++; 
        } 
       } 
      } 

      string localpath = @"c:\data"; 
      foreach (string str in path) 
       client.Export(str, localpath); 
     } 
    } 
}

如果我正确的，你明白你的问题对修订版之间的全球补丁不感兴趣。在这种情况下，您需要将每个修订版导出到单独的目录中，然后使用Beyond Compare之类的工具（或与WinMerge等效的任何东西）来识别修改后的文件。

但是，如果你的build目录是版本控制之下，那么你会过得更好创建一个补丁，并将其应用就可以了。

我创建一个批处理文件，将工作导出版本之间更改的文件。

@echo off 

FOR /F "tokens=1,2" %%I IN ('svn diff --summarize -r %1') DO (
    IF NOT %%I == D (
     IF NOT EXIST %2\%%J\.. mkdir %2\%%J\.. 

     svn export --depth empty -q --force %%J %2\%%J 
     echo %2\%%J 
    ) 
) 

要使用它，你只需在命令行上修改或修订范围和导出文件的目标。

C:\YourRepository>svnexport.bat 1:10 C:\Export
