Hi,
Below are two tests of using MatchData. The first is essentially Hal
Futon''s taken from The Ruby Way, 2nd. ed. [Thanks, Hal]. In
particular, m[0] returns the string being searched.
The 2nd is my humble use. For mine, m[0] returns the search pattern,
it seems,
I can''t anything in the code to account for this difference.
I''m
expecting the first kind of response in a Rails app I''m working on,
but I''m getting the second kind of response.
Any ideas?
Thanks in Advance,
Richard
BTW, I running Ruby 1.8.6 over WindowsXP-Pro.SP3
========= Test ========puts "\n1."
pat = /(.+[aiu])(.+[aiu])(.+[aiu])(.+[aiu])/i
str = "Fujiyama"
m = pat.match(str)
(0..5).to_a.each { |i| puts "m[%d]: %s" % [i, m[i].to_s] }
puts "\n2."
pat = /noun/i
str = "The ''noun'' word is here"
m = pat.match(str)
(0..5).to_a.each { |i| puts "m[%d] %s" % [i, m[i].to_s] }

In the first case /(.+[aiu])(.+[aiu])(.+[aiu])(.+[aiu])/i entirely matches "Fujiyama" in the second case /noun/i only matches a portion of the string, so that''s what is the value of m[0] -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Twitter: http://twitter.com/RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi Rick,> m[0] doesn''t return the string being searched, it returns everything > which the entire pattern matched.I got it! In Hal''s example, the matched string just happened to be the entire string. I didn''t realize that distinction, but I''m on board now. Thanks again for upteenth time for pulling my fat out of the fire.
