• torhu (5/19) Mar 11 2007 It's standard in regex syntax that the dot doesn't match a newline.
• 0ffh (4/13) Mar 11 2007 Well, that would appear to be the reason, then.

Hi,

just as a short note, is seems as if either

  a. the regex parser does not work as documented, or
  b. I have somehow messed up.

To be precise, http://www.digitalmars.com/ctg/regular.html says
that "." matches any character. I seem to have found at least
one exception, the newline character "\n".
Example the string "abc\ndef" is not matched by "^\".*\"$",
but is by "^\"(.|\n)*\"$".

Can anyone confirm?

Happy hacking,

It's standard in regex syntax that the dot doesn't match a newline. 
Should probably have been mentioned in the docs, though.

Usually there's modifier than makes the dot match newlines too, but I 
can't see one on that page.

As I have found a trivial workaround, it's just as well.... :)

Thanks, 0ffh
