Here is my hazel target. I thought of creating it as a task... but have been
too lazy. But, if someone wants to add the hazel task to Nantcontrib I don't
have a problem with that. This clears leaving behind a certain number of files,
but it could easily be changed to use age of file instead.
<target name="hazel">
<property name="hazel.searchPattern" value="*" overwrite="false" />
<script language="C#">
<code><![CDATA[
public static void ScriptMain(Project project)
{
string path = project.Properties["hazel.dirToClean"];
string searchPattern =
project.Properties["hazel.searchPattern"];
string [] folders =
System.IO.Directory.GetDirectories(path,searchPattern,SearchOption.TopDirectoryOnly);
System.Collections.ArrayList dirlist = new
System.Collections.ArrayList();
foreach (string folder in folders)
{
dirlist.Add(new DirectoryInfo(folder));
}
dirlist.Sort(new DirectoryInfoDateComparer());
dirlist.Reverse();
for (int i = 5; i < dirlist.Count; i++)
{
string foldername = ((DirectoryInfo)dirlist[i]).Name;;
try
{
((DirectoryInfo)dirlist[i]).Delete(true);
project.Log(Level.Info, String.Format("Deleted folder {0}",
foldername));
}
catch (Exception e) { project.Log(Level.Warning,
String.Format("Unable to delete folder {0}, {1}", foldername, e.Message)); }
}
}
internal class DirectoryInfoDateComparer : System.Collections.IComparer
{
public int Compare(object x, object y)
{
DirectoryInfo di1 = (DirectoryInfo)x;
DirectoryInfo di2 = (DirectoryInfo)y;
return di1.CreationTime.CompareTo(di2.CreationTime);
}
}
]]></code>
</script>
</target>
Here is an example of how I would call it:
<property name="hazel.dirToClean" value="${InstallDir}" />
<property name="hazel.searchPattern" value="CD
${version.major}_${version.minor}_${version.build}_${version.revision}_*" />
<call target="hazel" />
