How to use conditionals with expect.rb?

[Kazushi Sakuraba]

This is a shot in the dark since it appears nobody uses expect.rb.

Does anybody know how to use a conditional with IO.expect("")?

Everytime I enter a string that isn't expected into IO.expect(""), the
script just hangs and I can't do anything with the failure.

Well, at least RExpect has the ability to timeout when an unexpected
string is parsed. The verbose and log file absolutely bite though.

Can you post your script? I believe the point of expect is to just
keep accepting input till it gets the "expected" value - try entering
the right string after you enter the wrong one. Here's a sample
interaction with expect - I'm assuming ruby expect follows the same
behaviour:

martin@dabba ~ $ cat hi.exp
set timeout -1
expect "hello world\n"
send "we get signal!\n"

martin@dabba ~ $ expect hi.exp
how are you gentlemen?
somebody set up us the bomb
move zig!!!!!!
hello world
we get signal!

martin@dabba ~ $

There's no way to enter the correct Expect string since it hangs. Also,
don't even think of using RExpect. "RExpect is better than you'd
expect" my ass.
