To match newlines, you need a \n
in some places, and \r
in others. I'm not sure about which to use when either, but if the one doesn't work, try the other. In your case, use this:
\\(\n\\blabla
Question
I have several .txt files I must modify:
every
\(
\blabla
must become
\begin{equation*}
\blabla
notepad++ does find \\(
when I use \\(\r
. But when I input \\(\r\blabla
it does not find anything. I am a noob at regexp.

You can also use "Extended Search" option in "Search Mode" section. This will detect \r correctly. Enter search string as \(\r
.
Strictly speaking, you should use something like (?:\r\n|[\r\n])
to match any of the three most common line endings, \n
(Unix), \r\n
(DOS/Windows) or \r
alone (pre-OSX Mac). In this case I think it's safe to assume the line endings are all \r\n
or all \n
, which you can match with \r?\n
.
But you have a better option: \v
, the vertical whitespace shorthand. It will match a carriage return or linefeed, but not spaces or tabs. This works for me in NPP v6.5.5:
\\(\v+\\blabla
I'm assuming you want \\b
to match a backslash followed by b
, not a word boundary.
If you want to match any line break, use \R
. And, as Alan Moore said, to match a backslash \
followed by a b
, use \\b
:
\\(\R\\blabla
\R
matches \r
or \n
or \r\n
