Cleaning Up

Hi, I did some cleaning today: - I've updated the documentation on http://kilana.unibe.ch:9090/SmallWiki and added a few tests. - I removed the restriction to evaluate a call-back only once, because this caused some confusion in certain cases. I observed several people editing and viewing pages using the save-button and the back-button of the browser: the problem there is that the save-callback is considered to be evaluated several times, so this should work in a more convenient way now. - Structure>>references will return a set with all structures in the wiki pointing to the receiver. Structure>>referencesStartingAt: will do the same but the search will start at the given parameter. Try out this feature by adding the component References to your wiki. - When renaming a wiki-pages all references pointing to that page are now correctly updated. However there is still a problem when a the renamed structure appears in the middle of a path (only possible for folders), in that case nothing is done automatically yet. - I've introduced VisitorPluggable as a subclass of Visitor to make the use of visitors more easily. This allowed to get rid of a few other visitors. VisitorPluggable has the constructor #block:start: to get everything started. There are currently two subclasses called VisitorLinkInternal and VisitorStructure that both just evaluate the block for the appropriate wiki-items. The re-factored hierarchy looks now like seen on: http://kilana.unibe.ch:9090/SmallWiki/SmallWikiVisitors. As an example the two changes mentioned above are now implemented using this kind of visitor: Structure>>referencesStartingAt: aStructure | collection | collection := Set new. VisitorLinkInternal block: [ :link :structure | self == link target ifTrue: [ collection add: structure ] ] start: aStructure. ^collection Structure>>renameTo: aString ... VisitorLinkInternal block: [ :link | self == link target ifTrue: [ "fix link ..." ] start: self root. ... - The alt-attribute is now rendered correctly for images.
