Re: [Aspell-user] Can I get "edit distance" for the suggestions?

[Ethan Bradford]

Here's a proposal for the API: 
  We add the type AspellIntEnumeration (or maybe a better name --
lower-case L next to cap I is ugly, but it would be nice if it was like
AspellStringEnumeration).
  We add a call to extract that from an AspellWordList: 
     AspellIntEnumeration * scores = aspell_word_list_scores(suggestions);

Behind the scenes,  we add to AspellWordList a list of
scores.  The list of scores is set in Working::transfer when the
list of words is created.

The "edit-distance" is not stored in AspellStringEnumeration.  It is only
stored internally inside data structures in suggest.cpp.  Also its not a
simple edit-distance function that is used to rank the suggestions, but a
combination of several factors, most of them being closely related to an
edit-distance.  In the future other factors, such as frequency, may be
used to rank the suggestions.  The more correct term to use is "score".

As far as making the score available outside of suggest.cpp, I am not
against it.  I just haven't gotten around to it.  I will gladly accept a
patch to this effect, however I will be fairly picky about how it is done.
For example I won't accept something that hacks AspellStringEnumeration to
include the score.  A separate data structure should be used.  Also,
backwards compatibility will need to be maintained.
