Sending post commit emails from Subversion running on windows

Creating a hook in Subversion running on a Linux server it seems to be straight forward. When creating a hook on a Windows server the process is fairly straight foward as well but there are a couple of gotchas.

1. Make sure to set the environmental variables that you need or provide the full path for everything that you need because Subversion does not provide environmental variables.
2. Since the post-commit.cmd or post-commit.bat script is executed as a batch file in windows it is a lot more limited that a perl script in Linux. It is best to hand off the real work to powershell right away.

Create a file in the hooks folder of your repository and name it post-commit.cmd or post-commit.bat.

POST-COMMIT.cmd

SET REPOS=%1 SET REV=%2
SET SITENAME=name of you repository
SET SMTP_SERVER=server address
SET EMAIL_TO=email@domain.com,email@domain.com,email@domain.com
SET EMAIL_FROM=email@domain.com

%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe PATHTOFILE\emailer.ps1 '%SMTP_SERVER%' '%EMAIL_TO%' '%EMAIL_FROM%' '%SITENAME%' '%REPOS%' '%REV%'

emailer.ps1
