While working on continuous integration, I needed the name of the most recently created tag in a Subversion repository. So I wrote a little PowerShell script that would find the name for me by looking in the Subversion log.

most-recent-svn-tag.ps1

Param(
  [string]$Url = "svn://my.repo.url",
  [string]$Username = "krouwhorst",
  [string]$Password = "secret"
)

Function Get-SubversionLog {
  ([xml](svn log $Url --xml --verbose --username $Username --password $Password)).log.logentry | ForEach {
    $item = $_
    $_.paths.path | ForEach {
      $path = $_
      $item | Select -Property @(
        @{ Name='Author'; Expression={$_.Author}},
        @{ Name='Revision'; Expression={([int]$_.Revision)}},
        @{ Name='Message'; Expression={$_.msg}},
        @{ Name='Date'; Expression={Get-Date $_.Date}},
        @{ Name='Action'; Expression={$path.action}},
        @{ Name='Kind'; Expression={$path.kind}},
        @{ Name='Path'; Expression={$path.InnerText}})
    }
  }
}

Get-SubversionLog |
Where { $_.Action -eq 'A' -and $_.Kind -eq 'dir' -and $_.Path -like '*/tags/*' } |
Select Author, Revision, Date, Path |
Sort Date -Descending |
Select -First 1
