# [QUIZ] NDiff (#46)

Uhm, where are the solutions?

I usually see solutions posted on Sunday.
Here it is Mon afternoon, and I have not seen
any quiz traffic. Is my email playing tricks on me?

Only if my email is broken too. Haven't had time to fiddle with it myself yet, but it looks like I better find some...

Sigh, maybe it's just my lame quiz writing skills...

I really want to do this quiz as it looks quite interesting, but I'm
totally swamped with work. I won't have time to do it until next
weekend. But at least some thoughts here:

I would like to write a fdiff i.e. fuzzy-diff. That would behave as follows:

1. Specify fuzzycompare fields with regular expressions.
2. When comparing a row first extract the fuzzyfields from the row,
compare both rows and call a user-specified compare function on the
fuzzyfields.

That would allow for a more general compare approach. I.e.

number-diff:

fuzzyfields = /number-regexp/
compare = proc do | n1, n2| (n1.to_f - n2.to_f).abs < EPSILON end

space-diff:

fuzzyfields = /\s+/
compare = proc do true end

dist-diff

fuzzyfields = /\A.*\Z/
compare = proc do | s1, s2 | edit_distance(s1, s2) < 2 end

etc...

regards,

Brian
