This doesn't matches multiple "m"
a = "Im the prowerful man"
puts a.match(/(m)/im)[1]
Above code matches only first "m"
In perl usually i do
$a =~ m/(m)/sig
How to do similarly in ruby
Use string.scan
instead of string.match
where the match
function would return only the first match.
> a = "Im the prowerful man"
> a.scan(/m/im)
=> ["m", "m"]
> a.scan(/(m)/im)
=> [["m"], ["m"]]
Multidimensional array at the output is because of the capturing group present in your regex.
