How to require commit messages in VisualSVN server?

Question

We\'ve got VisualSVN Server set up as our Subversion server on Windows, and we use Ankhsvn + TortoiseSVN as clients on our workstations.

How can you configure the se

Here's a Windows Shell JScript that you can use by specifying the hook as:

%SystemRoot%\System32\CScript.exe //nologo <..path..to..script> %1 %2

It's pretty easy-to-read, so go ahead an experiment.

BTW, the reason to do this in JScript is that it does not rely on any other tools (Perl, CygWin, etc.) to be installed.

if (WScript.Arguments.Length < 2)
{
    WScript.StdErr.WriteLine("Repository Hook Error: Missing parameters. Should be REPOS_PATH then TXN_NAME, e.g. %1 %2 in pre-commit hook");
    WScript.Quit(-1);
}

var oShell = new ActiveXObject("WScript.Shell");
var oFSO = new ActiveXObject("Scripting.FileSystemObject");

var preCommitStdOut = oShell.ExpandEnvironmentStrings("%TEMP%\\PRE-COMMIT." + WScript.Arguments(1) + ".stdout");
var preCommitStdErr = oShell.ExpandEnvironmentStrings("%TEMP%\\PRE-COMMIT." + WScript.Arguments(1) + ".stderr");

var commandLine = "%COMSPEC% /C \"C:\\Program Files\\VisualSVN Server\\bin\\SVNLook.exe\" log -t ";

commandLine += WScript.Arguments(1);
commandLine += " ";
commandLine += WScript.Arguments(0);
commandLine += "> " + preCommitStdOut + " 2> " + preCommitStdErr;


// Run Synchronously, don't show a window
// WScript.Echo("About to run: " + commandLine);
var exitCode = oShell.Run(commandLine, 0, true);

var fsOUT = oFSO.GetFile(preCommitStdOut).OpenAsTextStream(1);
var fsERR = oFSO.GetFile(preCommitStdErr).OpenAsTextStream(1);

var stdout = fsOUT && !fsOUT.AtEndOfStream ? fsOUT.ReadAll() : "";
var stderr = fsERR && !fsERR.AtEndOfStream ? fsERR.ReadAll() : "";

if (stderr.length > 0)
{
    WScript.StdErr.WriteLine("Error with SVNLook: " + stderr);
    WScript.Quit(-2);
}

// To catch naught commiters who write 'blah' as their commit message

if (stdout.length < 5)
{
    WScript.StdErr.WriteLine("Please provide a commit message that describes why you've made these changes.");
    WScript.Quit(-3);
}

WScript.Quit(0);
