I have string
a = "ala $(ela) ola $(tola) lola $(p_ola) ".
And I need some magic function that works this way:
puts a.params
[“ela”, “tola”, “p_ola”]
How to do this?

just escape the ( and the $.
irb(main):001:0> a = "ala $(ela) ola $(tola) lola $(p_ola) "
=> "ala $(ela) ola $(tola) lola $(p_ola) "
irb(main):002:0> a.scan /$((\w+))/
=> [[“ela”], [“tola”], [“p_ola”]]
irb(main):003:0>

irb(main):002:0> a.scan /\$\((\w+)\)/
=> [["ela"], ["tola"], ["p_ola"]]

btw if you just want a one-depth array:
irb(main):004:0> a.scan(/\$\((\w+)\)/).flatten
=> ["ela", "tola", "p_ola"]

Also:
irb(main):010:0> a.scan(/$(([^)]*))/).map{|m| m[0]}
=> [“ela”, “tola”, “p_ola”]
