[sword-devel] Dictionary ordering

[Ben Morgan]

Strong's numbers are padded by 0, which is why they currently sort properly.

Such a sort order sounds a good idea (though perhaps not for the developers
;).
Modules produced in such a way wouldn't be compatible with Sword <= 1.5.11,
though.

I still suspect that sorting isn't quite as easy as specifying a simple sort
order such as you suggested.
Once diacritics enter into it (especially non-composed diacritics), things
could get a little more difficult.
Perhaps allowing the delimiter separated variables to be longer than 1
character long might help.

This still won't catch everything, but it would be a good thing to have - I
think I've seen english dictionaries which put "St. Something" entries at
the start of S...

As for the example 'tis, you can't catch everything. This is when you want
to do a search on the keys of the dictionary.

God Bless,
Ben
