I just found what looks like a bug in Ruby. Here's a simple script that
will expose this bug:
----
irb(main):001:0> x = 1
=> 1
irb(main):002:0> puts 'foo' + x.to_s +'bar'
SyntaxError: compile error
(irb):2: syntax error
puts 'foo' + x.to_s +'bar'
^
from (irb):2
----
I finally figured out that it was the Plus sign *right next* to the "bar",
*after* the "to_s" method that Ruby dislikes. If I insert a space, I get
the correct output. If I take out both spaces, I get the correct output.
It's only if there's a space after the "to_s" and none between the Plus sign
and string-in-quotes that it blows up.
That is:
puts 'foo' + x.to_s + 'bar' # this works
puts 'foo' + x.to_s +'bar' # doesn't work
puts 'foo' + x.to_s+ 'bar' # this works
puts 'foo' + x.to_s+'bar' # this works
Anyone know why this might be? Is there a proper place where I might pass
this information on? (I'm not on any other Ruby groups right now.)
I haven't played with it anymore, so I wonder if this bug exists with other
methods.
I'll try to remember to be consistent with my spaces moving forward.
Thought some of you might be interested.
Cheers. Paul C.
