How to write parentheses in replacement, using the "Regular expression" mode ?

[guy038]

Hi, @vuvanvui-vui, and All,

@vuvanvui-vui send me an e-mail, today, saying :

hello Guy, how are you today,
hmm i have a question on notepad ++

in Regular express mode i can’t replace something = “(”, “)”

exam: i want to replace: Guy = (Guy)
the () is lost in result
thanks and sorry for my bad english :D

As I think that the solution may be useful for others, I prefer to reply on our site !

Quite easy ! In the Replacement zone, you must simply escape the parentheses with the usual \ symbol ;-)). So :

SEARCH Guy

REPLACE \(Guy\) ( or even \x28Guy\x29 )

Notes :

• The six characters, which have to be escaped, with the backslash \ symbol, are :

  • The backslash symbol \
  • The left parenthesis (
  • The right parenthesis )
  • The dollar sign $
  • The question mark punctuation sign ?
  • The colon punctuation sign :

• The above signs have a specific meaning, in the Boost Format String library ! Just refer to :

http://www.boost.org/doc/libs/1_55_0/libs/regex/doc/html/boost_regex/format/boost_format_syntax.html

• Most of the time, in replacement, the $, ? and : symbols do not need to be escaped !

Cheers,

Haha. This is a question I asked more than a year ago, to which guy038 also gave valuable reply.
Seriously, is there a way to edit NPP wiki? I can’t find how to register. And the Regular Expression Page is incomplete and still has some obvious errors.

Funny enough: another same question.
