- README for expect
- by A. Ito, 28 October, 1998
- Expect library adds IO class a method called expect(), which
-does similar act to tcl's expect extension.
-The usage of the method is:
- IO#expect(pattern,timeout=9999999)
-where `pattern' is an instance of String or Regexp and `timeout'
-is Fixnum, which can be omitted.
- When the method is called without block, it waits until the
-input which matches the pattern is obtained from the IO or the time
-specified as the timeout passes. When the pattern is obtained from the
-IO, the method returns an array. The first element of the array is the
-entire string obtained from the IO until the pattern matches. The
-following elements indicates the specific pattern which matched to the
-anchor in the regular expression. If the method ends because of
-timeout, it returns nil.
- When the method is called with block, the array is passed as
-the block parameter.
