Question

I have a string variable in Ruby as follows:

puts $varString.class
puts "##########"
puts $varString

the output of the code above is:

String 
##########
my::FIrst::Line
 this id second line 
 sjdf kjsdfh jsdf 
 djsf sdk fxdj

I need to get only the first line from the string variable (e.g. my::FIrst::Line).
How can I get it?

Answer 1

# Ruby >= 1.8.7
$varString.lines.first
# => "my::FIrst::Line"

# Ruby < 1.8.7
$varString.split("\n").first
# => "my::FIrst::Line"

As a side note, avoid to use global (the $ sign) variables.
