Ruby/Development/chomp

Материал из Wiki.crossplatform.ru

Ruby method chomp removes that newline character from the end of the text in the $_ variable.

print "Please enter the temperature: "
gets
chomp
puts "The temperature is #{$_}."

you don"t need to use $_ with gets - you can assign the text it reads to any variable: temperature = gets

print "Please enter the temperature: "
temperature = gets
$_ = temperature
chomp
temperature = $_
puts "The temperature is #{temperature}."
