Array String.match(Regexp)

Hi

I’d like to know, what is the easiest way of doing the perlish

($i,$j,$k) = $_ =~ /delim(\S+):(\S+):(\S+)/

=~ operator in ruby returns nil/number
I have found just one solution, which uses global $variables.

$.sub( /regexp(with)_multiple(.*)/ , “” ) ;
i = $1 ;
j = $2 ;
k = $3 ;

But I don’t like global variables. Ruby functions can return
everything…
a = $stdin.readlines()
So isn’t there somewhere
String.match( Regexp ) that returns Array of matches ?

Hi Suk

foo = "junkdelimabc:def:ghi"
    m = /delim(\S+):(\S+):(\S+)/.match(foo) # m is a MatchData object
    p m.to_a # >> ["delimabc:def:ghi", "abc", "def", "ghi"]

i.e. m[1] is like $1, m[2] is like $2 etc.

Regards,

Brian.

You can do:

all, i, j, k = */delim(\S+):(\S+):(\S+)/.match($_).to_a
