IO.expect: where can I find documentation?

ruby-talk
1

Hey all --

Can anyone point me to the documentation (or the source!) that defines
the IO.expect method (parameters, return values, etc.)?
I can't seem to find it anywhere.

Also, I'm interested in extending this routine to use Floats (not just
Fixnums) as timeout values (for a granularity of, say, 50
milliseconds).

Thanks,
-- Dan C.

I do not know about that. Could you mean REXML.expected? That is the
closest thing I can think. RDoc Documentation should have most
all the documentation there is.

Dan,
Where are you finding IO.expect ??
My Ruby (1.8) doesn't seem to have it. ri tells me nothing.
Creating an IO object:
i = IO.new 2
( the handle for stderr )
Then doing:
i.methods.sort
Returns no method expect. Are you using some library that extends the IO class?

It's expect.rb from the standard library pty extension. The docs are
in the source:

http://svn.ruby-lang.org/repos/ruby/trunk/ext/pty/README
http://svn.ruby-lang.org/repos/ruby/trunk/ext/pty/README.expect

Thanks, Jordan!

So it looks like the timeout value is really only passed to
IO#select. Would this imply then that Floats as well as Fixnums could
be used?

I personally don't see why not, but the docs clearly say only a Fixnum
can be used as a timeout value. [ shrug ]

What do y'all think?

Have a floatnum regex for 'pattern' /\d+.\d+/ ?

You can pass a Float to #select.
