Export the changed files from visual svn on current commit visual svn server on windows (powershell script)

问题

Need to export the changed files from visual svn on current commit visual svn server on windows.

I tried using windows power shell script and bat file on post-commit to achieve this.

I'm new to poswershell scripting.

I got the code to export current revision. It is as follows.

# Store hook arguments into variables with mnemonic names
$repos = $args[0]
$rev   = $args[1]

# Build path to svn.exe
$svn = "$env:VISUALSVN_SERVER\bin\svn.exe"

# Build url to repository
$urepos = $repos -replace "\\", "/"
$urepos
$url = "file:///$urepos/"

# Export repository revision $rev to the C:\test folder
&"$svn" export -r $rev --force "$url" F:\test_live

It will export the files on the revison on that commit ($rev) to F:\test_live

But I need to export only changed files. Is their any way to do?

I think we can achieve thsi by using SVN diff, SVN log commands.

The bat file I'm using is

@echo off

set PWSH=%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe
%PWSH% -command $input ^| %1\hooks\post-commit.ps1 %1 %2  
if errorlevel 1 exit %errorlevel%

$repos = "C:\Repositories\siterepo"
$rev = $args[1]
$prev_rev = $rev
$prev_rev -= 1

# Build path to svn.exe
$svn = "$env:VISUALSVN_SERVER\bin\svn.exe"

# Build url to repository
$urepos = $repos -replace "\\", "/"
$urepos
$url = "file:///$urepos/"
$url

$diff_var = &"$svn" diff --summarize -r $rev:$prev_rev $url
$dif_var
$check = "System.String".CompareTo($diff_var.GetType().FullName)
if ($check -eq 0)
{
    #"single file"
    $source_file = $diff_var.Substring(8)
    $source_file
    $destination_file = "C:\mywebroot\"+$diff_var.Remove(0,41)
    $destination_file
    #check directory
    $dir_path = Split-Path $destination_file
    $dir_path
    if ((Test-Path $dir_path) -eq 0)
    {
        #"folder_not exist"
        New-Item -Path $dir_path -Force -ItemType Directory
    }
    else
    {
        #"folder exist"
    }
    &"$svn" export --force $source_file $destination_file
}
else
{
    #"multiple files"
    $num_files = $diff_var.Length
    #"loop"
    for ($i=0; $i -lt $num_files; $i++)
    {

        $source_file = $diff_var[$i].Substring(8)
        $source_file
        $destination_file = "C:\mywebroot\"+$diff_var[$i].Remove(0,41)
        $destination_file
        #check directory
        $dir_path = Split-Path $destination_file
        $dir_path
        if ((Test-Path $dir_path) -eq 0)
        {
            #"folder_not exist"
            New-Item -Path $dir_path -Force -ItemType Directory
        }
        else
        {
            #"folder exist"
        }
        &"$svn" export --force $source_file $destination_file

    }
}

Known BUGS :

folders/file's name with "space" cannot work well
Delete functionality is not included.
