Find and replace with a newline in Visual Studio Code
(11 answers)
Closed 6 years ago.
I can replace some text with \n if i enable the regex by clicking the regex icon next to the find input box.
But when i try to find a newline, i can't get it to work. I tryed to find \n and [\n]. But none worked. The only solution which worked was [\s] but it's not ideal. But for now it better then nothing i guess.
Is it possible to find a newline in VSCode?
It would depend on the new line settings of your system, but in general on windows a new line is made from two characters, a carriage return \r followed by linefeed \n.
So the regex for a new line is \r\n

Is there a difference between [^\b] and .?
I was modifying some code created by someone else that included this no-word-boundary-character-class ([^\b]). and am not able to find a difference between that and wildcard . (this is in ruby).
My assumption was that [^\b]+ when applied to the string hello world should match hello and stop before the space, (as that is where there is a word boundary.
My observation is that it seems to just match everything. rubular link.
What should be happening here?
[\b] means backspace and [^\b] not a backspace
\b is not a character, it can't be included in a character class.
The negation of a word boundary is \B

All I found again and again was this:

Two questions:
I know that \n is new line, \t is tab, but what is \r and \f?
How do I search for them? What keyword should I use in Google?
carriage return and form feed respectively. As for how to google, "whitespace characters" worked for me

Enter in MessageBox:
My Message:
Warning:
Do you want to continue?
Code:
MessageBox.Show("Warning: {ENTER(?)} Do you want to continue?");
Rather than the {ENTER(?)} to send enter code and message divide to two line.
Please try
MessageBox.Show("Warning:\nDo you want to continue?");
\n stands for NewLine. You can use Environment.NewLine, too. Please check out this Question

I need to do a find and replace, where I need to replace 2 lines at time. Does anyone know how to do this in the VS2008 IDE?
To clarify, i want to replace 2 lines with 1 line.
Many thanks
Thanks to František Žiačik for the answer to this one.
To perform a find/replace, replacing multiple lines, you need to switch on regular expressions and use a line break (\n) between your lines, also using (:b*) at the start of each line to handle any tabs or spaces tabs.
So to find:
line one
line two
you would search for ":bline one\n:bline two" (without the quotes)
Try Multiline Search and Replace macro for Visual Studio.
You can activate the 'Use regular expressions' in the find dialog, and use \n to match a newline.
In your case, type FirstLine\n:Zs*SecondLine.
:Zs* skips leading blanks on line 2.
For example ,\n:Zs*c matches a comma, newline, any number of blanks, a 'c'.
Sometimes i would like to search for text containing a new line character and there are other times i would like to replace text with a new line character.
How can i do this with visual studio 2008?
Use a RegEx search:
In the Find Dialog - Expand "Find Options"
Check the box for Use: Regular Expressions
Next to the search box there is now an arrow that is active, it will show you available RegEx options/values.
The value you want will be \n. So "SearchValue\n" should do it.
Be aware that that its not a standard RegEx that you use, it's VS specific.
Replace can also use the RegEx values.
Adding on to Brian Schmitt's answer...
Regular expression searches using \n work as expected. However you have to be a little careful when using \n in regex replaces with Visual Studio 2008. For example, if you search for \n and replace with \n (yes, the exact same thing) all of the line breaks in your file(s) will be converted to Unix-style newlines (LF). This may be a bug in Visual Studio. I find it hard to believe this is the intended functionality.
To get around this, you can use tagged expressions, using curly braces: e.g. search for SearchValue{\n} and replace with ReplaceValue\1. This ensures that the same line-break character(s) that were found when searching will also be used when replacing.
You can try my Multiline Search and Replace Macro.
