问题
i see that all I can set to is %repos% and %txn%
how can I use those to get to the commit message (in my case, so i can parse out the ticket number so i can see if it exists in the bug database before committing to it)
回答1:
Using a recent SharpSvn release you can use
SvnHookArguments ha;
if (!SvnHookArguments.ParseHookArguments(args, SvnHookType.PreCommit, false, out ha))
{
Console.Error.WriteLine("Invalid arguments");
Environment.Exit(1);
}
to parse the arguments of a pre-commit hook and then use
using (SvnLookClient cl = new SvnLookClient())
{
SvnChangeInfoEventArgs ci;
cl.GetChangeInfo(ha.LookOrigin, out ci);
// ci contains information on the commit e.g.
Console.WriteLine(ci.LogMessage); // Has log message
foreach (SvnChangeItem i in ci.ChangedPaths)
{
}
}
to get to the log message, changed files, etc.

I do not know SharpSVN, however if you create a hook script as you describe, you get as arguments %repos% and %txn%
With these data you can look into the transaction (%txn%) of the given repository. Usually you do this by using
svnlook -t %txn% %repo%
Then you will get the log-message.
So you should look for an equivalent to svnlook in sharpSVN interface.

Some time ago I've written a C# wrapper for the svnlook.exe. I used this one to send commit messages to a bug tracker (if a ticket id was provided). Find it below, maybe it is useful for you.

I've just gone through the process of building a hooks app myself and SharpSVN isn't required for looking at commit messages. Assuming you've built yourself a console app already, try this code which calls svnlook.exe directly:
string repos = args[0];
string txn = args[1];
var processStartInfo = new ProcessStartInfo
{
FileName = "svnlook.exe",
UseShellExecute = false,
CreateNoWindow = true,
RedirectStandardOutput = true,
RedirectStandardError = true,
Arguments = String.Format("log -t \"{0}\" \"{1}\"", txn, repos)
};
Process process = Process.Start(processStartInfo);
string message = process.StandardOutput.ReadToEnd();
process.WaitForExit();
return message;
Make sure the location of svnlook.exe is added to the path environment variable of your machine so the above can be executed from any location.
