Subject [jira] Commented: (JSPWIKI-526) Allow administrators to select the Comparator used for sorting page lists by name
Date Mon, 27 Apr 2009 11:49:30 GMT


Greg Kable commented on JSPWIKI-526:

Thanks for the tips Janne.

Attached is the patch for the current 2.8 trunk.  I decided to implement on 2.8 first because
I have production wiki running 2.8 and the 2.8 code is more stable.  The patch ended up a
little bigger than I expected because I added in some extra stuff.

The brief summary of the jspwiki-526-PageSorter.patch is:

- Added a new JSPWiki property  called jspwiki.pageNameComparator..class which specifies a
Comparator<String> class to be used as the default sort order for pages sorted by name.
- Added a util class PageSorter which wraps up the pageNameComparator. This class is initialised
by and made available through WikiEngine.  For a future change, I think it would be better
as a User preference rather than a global property.
- Added a couple of Comparators which can be used as the default comparator.  I couldn't find
a "human" comparator so I created one.  If you know of one, we can use it instead.
- Changed all places I could find where pages were presented in alphabetical order to use
- Added a new sortOrder parameter to AbstractReferralPlugin as suggested by Santiago Gala

All tests pass bar one WikIEngine test which seems to be invalid anyway.  I also have the
patch in production on a small but fairly active wiki.

> I personally hate the order of pages returned by the standard sorting routines and would
rather an order that understood numeric ordering.  That is, instead of having the list:
> WikiPage1
> WikiPage10
> WikiPage2
> I'd like to get the list:
> WikiPage1
> WikiPage2
> WikiPage10
> There are also many other case, especially for localisation, where being able to set
the page name order would be useful.
> To achieve this, I propose adding a JSPWiki property which specifies the Comparator to
be used for page names.  Before I do the work and submit a patch, I'd like to know:
> - Would this be a welcome feature?
> - Is jswpwiki.pageNameComparator an appropriate property name?  If not, what do you suggest?
