NTemacs: in NEGATED char-class, how to show newline? [^n]+ goes one too far.

NTemacs: in NEGATED char-class, how to show newline? [^n]+ goes one too far.

subj: NTemacs: in NEGATED char-class, how to show newline?  [^\n]+ goes one too far.

Remember that this is "ntemacs" (google it, you'll see), running under
WINDOWS xp, where line-ends are the old DEC crlf.



--- NEITHER OF THESE TWO STOP AT EOL -- KEEP GOING UNTIL EOF!

(query-replace-regexp "[^\\n]+"     "BEGIN--\\&--END"      nil (if (and transient-mark-mode mark-active) (region-beginning)) (if (and transient-mark-mode mark-active) (region-end)))

Here I added a line-feed, since windows uses crlf(?) as newline:

(query-replace-regexp "[^\\n\\j]+"     "BEGIN--\\&--END"      nil (if (and transient-mark-mode mark-active) (region-beginning)) (if (and transient-mark-mode mark-active) (region-end)))



MATCHES ONE TOO FAR: (query-replace-regexp "http://[^ \\t\\n]+"     "<LI><a href=\"\\&\"\\&<--LINK</a>"      nil (if (and transient-mark-mode mark-active) (region-beginning)) (if (and transient-mark-mode mark-active) (region-end)))


http://www.google.com/  <--- matches all of this,

http://www.google.com/  <---- PLUS the first char ("h") of this one.

Thanks!

Give a man a fish, and you've fed him for a day. Teach him to fish,  
and you've depleted the lake.

Emacs uses LF line ends internally, converting on read and write
(unless you explicitly use binary or *-unix as your coding system).

Does the following work any better?

(query-replace-regexp ".+$" "BEGIN--\\&--END" ...)

Also, try M-x regexp-builder to see in real-time what your regexp will
select.

My guess is that there are no n or \ characters in your buffer, and
you've escaped the backslash in a context where it doesn't need
escaping.
