Continued Strings

[James Edward Gray II]

Here's an interesting code fragment from a Ruby Quiz solution this week:

puts "\nShortest path from #{m.pos2coord(p1).inspect} to " \
"#{m.pos2coord(p2).inspect}:", m.to_s(path)

Does Ruby concatenate those two String fragments because of the \
line continuation? I didn't know that.

puts "Yes..." " " "it does"

Nope, try it in irb. No backslash necessary:

"foo" "bar" # => "foobar"

(I didn't know that worked either, or i had forgotten. Cute.)

This is (last I heard) going away with rite. You may want
to avoid this feature.
