usage of Regexp::EXTENDED

[Simon Strandgaard]

How does it work ?


I tried
assert_match(/bc/x, "ab cd")
But it fails...


ProgrammingRuby says:
EXTENDED Ignore spaces and newlines in regexp.

Hi,

At Wed, 8 Oct 2003 20:48:17 +0900,

I tried
assert_match(/bc/x, "ab cd")
But it fails...

/bc/x has no spaces.

ProgrammingRuby says:
EXTENDED Ignore spaces and newlines in regexp.

But not ignore spaces and newlines in the target string.

Try: assert_match(/b c/x, "abcd")

Try: assert_match(/b c/x, "abcd")

that works.. but

assert_match(/b \nc/x, "abcd")

fails ?

programming-ruby says that newlines will be ignored?
