Splite string to text and integer

I wanna know if there is a quick way to solve the problem in ruby like example below

example "t12" => text="t", value=12

"ad15" => text = "ad", value = 15

"acbds1687" => text = "acbds", value=1687

I think regular expression may can solve this but I am not sure about regular expression.

If you give create a capture group it stays in the split, thus this code is pretty slick:

text, value = string.split(/(\d+)/)

or you can use the slice! method:

text  = 'sagasg125512'
value = text.slice!(/\d+/)
p text  #=> "sagasg"
p value #=> "125512"

To parse the string into a hash like { :text => "t", :value => 12 }:

def parse (string)
  matchdata = string.match(/([a-zA-Z]+)([\d]+)/)
  text = matchdata[1]
  value = matchdata[2].to_i

  return { text: text, value: value }
end

To parse the string into an array like ["t", 12]:

def parse (string)
  matchdata = string.match(/([a-zA-Z]+)([\d]+)/)
  text = matchdata[1]
  value = matchdata[2].to_i

  return [text, value]
end

Like below:

irb(main):001:0> "t12".split(/(?<=[a-zA-Z])(?=\d)/)
=> ["t", "12"]
