Question

Is there any single-line string literal syntax in Ruby that allows string interpolation but does not interpret a backslash as an escape character?

I.e.,

Where ruby_var = "foo"

I want to be able to type the equivalent of C:\some\windows\path\#{ruby_var}\path resulting in the string C:\some\windows\path\foo\path without having to escape the backslashes or resort to a multi-line heredoc.

puts "C:\some\windows\path\#{ruby_var}\path"
puts "C:\some\windows\path\path_#{ruby_var}\path"
=> C: omewindowspath#{ruby_var}path
=> C: omewindowspathpath_foopath

puts 'C:\some\windows\path\#{ruby_var}\path'
puts 'C:\some\windows\path\path_#{ruby_var}\path'
=> C:\some\windows\path\#{ruby_var}\path
=> C:\some\windows\path\path_#{ruby_var}\path

puts %{C:\some\windows\path\#{ruby_var}\path}
puts %{C:\some\windows\path\path_#{ruby_var}\path}
=> C: omewindowspath#{ruby_var}path
=> C: omewindowspathpath_foopath

puts %q{C:\some\windows\path\#{ruby_var}\path}
puts %q{C:\some\windows\path\path_#{ruby_var}\path}
=> C:\some\windows\path\#{ruby_var}\path
=> C:\some\windows\path\path_#{ruby_var}\path

Answer 1

ruby_var = "hello"
puts 'C:\some\windows\path\%s\path' % ruby_var
#=>C:\some\windows\path\hello\path
