Patrick,
Say I have this file:
----8<-cut-here----
one
two
----8<-cut-here----
(Line 2 and 4 are empty, line 3 consists of four spaces.)
And this pattern: ^\s*$
Shouldn’t it match these three ranges?
- zero chars on line 2
- four spaces on line three
- zero chars on line 3
Instead, it seems to match only one range:
- 6 chars: the linefeed at the end of line 2, the four spaces on line
three, and the linefeed at the end of line 3.
I’m still not seeing why ^\s*$ would match chars 5 through 10 (the
first empty line AND the line with 4 spaces) in one fell swoop, but
would not match char 11 (the 2nd empty line).
Shouldn’t it match these three ranges?
- zero chars after char 4
- four chars (“ ”) starting with char 6 and ending with char 9
- zero chars after char 10
Confused!

^\s*$ does not work for me in BBEdit. BBEdit does not find the empty
lines that proceeds the line containing "four" or the line containing
"six" in my test file.
It isn't expected to, since $ explicitly matches the position
_preceding_ the nearest line end:
[Chapter 8: Searching with Grep / page 166]
It is important to note that ^ and $ do not actually match return
characters. They match zero-width positions after and before
returns,
respectively. So, if you are looking for “foo” at the end of a
line,
the pattern "foo$" will match the three characters "f", "o", and
"o".
If you search for "foo\r", you will match the same text, but the
match will contain four characters: "f", "o", "o", and [the
linebreak which follows].

Patrick Woolsey
