PowerShell, Subversion One Liner

August 26, 2007

([xml](svn info C:\Code --xml)).info.entry.revision

Returns the revision number of a subversion working copy.

Wrap it in a function

function Get-SvnRevision($dir)
{
([xml](svn info $dir --xml)).info.entry.revision
}

This comes in handy when building scripts to interact with Subversion.

Automating an svn update, compiling the code and producing executables with the svn revision number burned in for QA and Customer tracking.

$log = [xml] (svn log http://svn.smartorg.com/svn/dev/SpikeTests –xml); $log.log.logentry | ft author, msg -auto | more
Richard Howells 07.21.12 at 6:46 am: Hi Doug,

The function version has only one ‘-’ before the xml.

I could not get the PowerShell function version to work until I modified -xml to –xml. I’m a PowerShell noob. Did I miss somthing?

Thanks.
Doug Finke 07.22.12 at 8:33 am: Thanks for the comment Richard. You are correct.
The HTML had the –xml. I wrapped it in a pre tag and now it shows up in the post.

Thanks for catching that.

Doug
