Recently, on Notepad++, I want to reduce number of spaces at begin of lines.
I searched a Regular Expression, but I don't find any.
On a array(=tab) of Notepad++, I have following lines
<html>
<body>
<p>ligne normale</p>
<p>ligne with 2 spaces </p>
and I want to reduce (= divide by 2 number of spaces) only spaces before '<' character on all lines.
Waiting result is following
<html>
<body>
<p>ligne normale</p>
<p>ligne with 2 spaces </p>
I tried following Regex and string replacement
Search: \s{2}(?<=^\s*)
Replace: (= one space)
but Notepad++ refuses this Regex !
I have then tested the same Regex on a C++ program that is using PCRE version 7.8.
It indicates that look-behind can only contain fix length string !
Is there a Regex that can do the job ?
PS: the following Regex that use a look-ahead to the job ... partially !
\s{2}(?=(\s{2})*<)
The last 2 spaces in last line, just before last
are not in the margine and are removed while they must be kept !I have not tried it on Notepad++, but this only uses very basic regular expression features in order to halve the number of start-of-line spaces:
Find what: ^(\s+)\1
Replace with: $1
