This page describes a modification to Wiki to add a Cancel button to the web editing page.

The patch is against Wikit version: 2003/08/20 19:06:22 68261-69214.

A wikit.kit containing this and other patches is available for download, please see [AKG Wikit] and [AKG].

Note that this patch doesn't handle the "Page Saved" message very well (it says saved when editing is cancelled).  This is fixed in [AKG Wikit].

Extend the patch to allow the page to be renamed.  As with the Tk interface, all references are automatically renamed.  This patch superseeds the one above.

'''Warning:'''  The patch as presented below is simplistic.  If you rename a page to an existing page name, the more recently created page will become inaccessible.  I've improved the behaviour, by not saving the change in page name if there is a conflict, in the wikit.kit that is available for download from [AKG].  Even better behaviour would be to warn the user that there is a name conflict (but that is a much larger job :-)).
