Hi I’m trying to run this code:
while (line = gets)
puts “The given line is #{line}”
if line =~ /^eval:(.*)$/
puts “#$1 # => #{eval $1}”
end
end
That I found on a tutorial website. Ruby gives me this error when I try to run it:
ruby guessnumber.rb
higuessnumber.rb:4:in `gets’: Bad file descriptor (Errno::EBADF)
from guessnumber.rb:4
Exit code: 1
Why is this happening?
This codes run mighty fine on my win2k, 1.8.1 build. Does the error occur
when you run the script period or when you type something in after the
script is run? Also, what build and on what system are you running this on?

Are you running this through an Editor (may be SciTE or TextPad?)
IF that is the case then try it from the command prompt.

Yes I am (SciTE). I’ll try it out without when I get back to my
computer on Sunday. Is there any way to get it to work with SciTE
though? It’s so convenient to just hit f5 and you can see the
program’s output.

This problem was fixed in later versions of SciTE.
There’s a good one-click installer (v 1.57 unless you want
Lua scripting support) here:
Make sure you won’t overwrite your customised properties files.
You may need to refer to the way things were, later.

Indeed it is.
Which is one reason I use RDE:

(not as straightforward to install, but it does a whole fat lot more)

Yes, there is :
Works for me on Windows XP (Home Edition).
