In this case Ruby uses the structure case...when 

case objeto
when 1
  puts "Seu número é 1"
when 2..10
  puts "Seu número está entre 2 e 10"
when 11,13,17,19
  puts "é um número primo entre 10 e 20"
when String
  puts "é uma String"
else
  puts "Qualquer outra coisa."
end

You can create this structure without parameter as well 

case
when objeto < 10
  puts "Menor que 10"
when objeto == 10
  puts "Igual a 10"
when (10..20) === b
  puts "Alguma coisa entre 10 e 20"
end

And also Ruby interprets all kinds of statements as case when/ if else anyway ... That is: 

    objeto = 1
    variable_to_return = case objeto
                           when 1
                             10
                           else 
                             'UAHEUHAUEHUAEHUAE sou uma String!'
                         end
   puts variable_to_return  # => 10

Using val () in script causes me to lose line breaks ___ ___ erkimt Exclusion via regex ______ qstntxt ___

I have the following string:

%pre%

It is a format %code% and is wrong because after the time there is %code% . To catch this snippet I used %code% :

%pre%

How can I remove only the ending considering that I have many occurrences?

To capture the microsecond you can use the following regex %code% it says to capture at the end of the string a dot followed by one or more digits followed by a double quotation mark which is a group. In the substitution field, place %code% or %code% is the value of the group catch in the case double quotation.

= > ^ catch in the example:

%pre%

I imagine it is captured to be replaced by something else.
