Perhaps you mean :single-line-mode ?
The Perl terminology can be confusing (I always have to look it up!) cl-ppcre says:
The symbols :CASE-INSENSITIVE-P, :CASE-SENSITIVE-P, :MULTI-LINE-MODE-P, :NOT-MULTI-LINE-MODE-P, :SINGLE-LINE-MODE-P, and :NOT-SINGLE-LINE-MODE-P are equivalent to Perl's embedded modifiers "(?i)", "(?-i)", "(?m)", "(?-m)", "(?s)", and "(?-s)".
perlre says:
m Treat string as multiple lines. That is, change "^" and"$" from matching the start or end of the string to matching the start or end of any line anywhere within the string.
s Treat string as single line. That is, change "." tomatch any character whatsoever, even a newline, which normally it would not match.

If I can pull people attention away from the International Lisp conference (!)...
Perhaps I'm missing something but both
(cl-ppcre:scan (cl-ppcre:create-scanner "(.*?)c.*?") "a b c d e")
and
(cl-ppcre:scan (cl-ppcre:create-scanner "(.*?)c.*?" :multi-line-mode t) "a b c d e")
return the same values: 4 5 #(4) #(4).
I expected the second form to return 0 4 #(0) #(4). Where have I gone wrong...
thanks.
