[Dev] more parcel stuff (while i'm thinking about it)

[Geoff Gerrietts]

Last night I more or less got the hyperlinks in the repositoryviewer
integrated into the URL navigation scheme. I have a couple things left
over from that which may or may not bear discussion.

- "URLs" don't really conform to what I think of as the URL standard.
  That doesn't cause any significant functionality issues, yet, but it
  does create a sort of cognitive disconnect for users. It could also
  make integration with "real" URLs "interesting", across some range
  of not very amusing values for "interesting".

- The sidebar currently expects to match the entirety of the URL to
  one of the labels in its list. It does a nice job of handling
  embedded slashes to represent hierarchy. But, it doesn't allow for a
  parcel like RepositoryViewer, where you don't want all possible URL
  values in the sidebar. I would suggest maybe the ChandlerWindow ask
  the individual parcels what pieces of the URL to match against. For
  example, in ChandlerWindow.py, @line 495:
  
            if parcel == None:
                return false
        
        self.isRemote = remoteaddress != None
            
        urlstub = parcel.sidebarLabel(remoteaddress, localurl)
        self.sideBar.model.SelectURL(urlstub)
        if doAddToHistory:
            self.navigationBar.model.AddURLToHistory(url)
        self.navigationBar.model.SynchronizeView()
        return parcel.GoToURL(remoteaddress, localurl)

  This may violate the current model of responsibilities: maybe the
  parcel isn't actually /supposed/ to be in control of its
  representation in the SideBar? But it's a suggestion; right now
  the SideBar doesn't update quite as we might wish.


Changing the first item would be a lot of work, I think, but it's
probably do-able. Changing the second item isn't so much work, but
it's "sweeping" insofar as it gives every Parcel opportunity to
override the URL-matching behavior.

Thanks,
