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 "." to  

match any character whatsoever, even a newline, which normally it would not match.

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.
