Notepad++ Advanced search and replace. Null, Enter char, Tab, Regular Expressions, Etc.
Open the find/replace dialog.
At the bottom will be some Search mode options. Select "Extended (\n \r \t \0 \x...)"
In either the Find what or the Replace with field entries, you can use the following escapes:
\n new line (LF)
\r carriage return (CR)
\t tab character
\0 null character
\xddd special character with code ddd
- [!] finds the exclamation character.
- .* selects the rest of the line.
- (\+.*)(Item) \+ finds the + character. | .* selects the text after the + up until the word "Item" | Item finds the string "Item" | () allow us to access whatever is inside the parentheses. The first set of parentheses may be accessed with \1 and the second set with \2.
- \1\r\n\2 will take + and whatever text comes after it, will then add a new line, and place the string "Item" on the new line.
- A-Z finds all letters of the alphabet in upper case.
- a-z finds all lower case letters.
- A-Za-z will find all alphabetic characters.
- [^...] is the inverse. So, if we put these three together: [^A-Za-z] finds any character except an alphabetic character.
- Notice that only one of the [^A-Za-z] is in parentheses (). This is recalled by \1 in the Replace with field. The characters outside of the parentheses are discarded.

Any way of preserving case during a find/replace?

e.g.

userlogin => consumerlogin,
USERLOGIN => CONSUMERLOGIN,
UserLogin => ConsumerLogin,

This works but obviously the strings are static which is not ideal for quick usage. It also only covers lowercase, UPPERCASE and Sentence case rather than respecting case as a whole.

  • Find: (?:(U|(u))((?:(SER|(ser)))))
    • (Match case must be ticked)
  • Replace: (?2:\u)(?5:\U)consumer

Please assist, I am trying to find a specific ASCII symbol and I need to replace is with another. How do I do that. I used the find function in Search > Find Character in Range however it does not allow to me to search for a specific ascii number (148) and I need to replace that with an another symbol.

Actually \n\r doesn't work (v7.3.2). Use \r\n instead. Works like a charm.

Thanks for this, got it bookmarked in np++ for quick reminders now.

If anyone is interested I'd recommend regex101.com to work on more involved patterns before moving them into np++—its a nice sandbox w/ test text and substitution, as well as a big (but less np++ specific and not entirely beginner friendly) reference library. It also lets you save your patterns if you log in w/ your github(/google/twitter) account or even view other's publicly posted regex examples. The last part I mentioned is great if you're asking how to do basic stuff in comment threads with no answers tbh

Although np++ uses PCRE which is the default flavor on the site I have had a few little issues transferring between them, keeping a list like this in np++ for fixing little differences is advised lol

Hi, I'm trying to run a regex with the global flag, so it would only bring back unique/distinct (last) match of every match. I got some guidance here:
https://stackoverflow.com/questions/46545647/regex-to-find-unique-occurences-of-a-match#46545647
with an example here: https://regex101.com/r/ozFNPV/1

But how do I turn on the g (for global) flag in the Notepad++ search in files Regular Expression search?

dear devs & fans,

I'd like to know if it's possible following:

  1. having a folder, where are multiple files no matter the extension is ...
  2. multi find & replace like:
    if find NAME 1, replace it with NICK1
    if find NAME 2, replace it with NICK2
    ..... up to 400-500 records
  3. so find and replace all matching records with their pairs (pseudonyms) in multiple files at once (including subfolders if possible) ...
    is it possible within notepad++ ? any special plugin or so ?

Many thanks in advance !

Hi.

I want to modify a .sql to change table/column names preffix/suffix. The generated sql uses id as PK suffix. I want to use cod, as a preffix.
So replacing id for cod isn't enough. How would I go about doing that with regex?

I know this is quite old, but for people with a similar problem, maybe something like this:
([0-9])[^:]
([0-9]) is the group for all numbers, and [^:] breaks that group if there's a colon (poorly explained due to the lack of my english knowledge)

When I press the Enter key while editing an indented line, the cursor begins the next line aligned with the indentation of the previous line. When I use '\n' or '\r' in a search/replace operation, it does not align to the indentation of the previous line. Am I doing something wrong? It seems to me that '\r' should act just like the Enter key, no?

I realize this is old, but for anyone's future reference, the issue is that while Notepad++ automatically inserts previous indentation when inputting new lines, the search/replace function isn't aware of this. You need to include the necessary indentation in your search/replace.

The easiest way is merely drag-selecting the beginning part of that line (the empty indentation spacing) and then press CTRL-H to open "Replace" dialog. It will be pre-filled with the necessary search to locate that pattern of indentation. And then you can prepend a "\n" to the start of it to only search for new lines that start with that level of indentation.

Depending how your NP++ is set up to manage indentation - i.e. a tab vs. spaces - you may be able to utilize extended-search's "\t", which indicates a "tab".

For reference, an "Enter" for a newline (as it seems you're asking) equates to "\r\n", which is a carriage return + line-feed/newline operation, which is what the "CR LF" symbols are referencing at the end of each line, if you were to enable "Show symbols". This is a throwback reference to the days of the typewriter, where the "Enter" button equivalent merely dropped the cursor down one line, but wouldn't automatically bring it to the leftmost start of the line by default.

Enable the "Extended" search selector, and then in the "Find" box, add an "\r\n" to the right of your semicolon, e.g. ";\r\n". That will find only semicolons that are at the end of lines.

Note that if you are doing a "Replace" operation, you'll also need to add the "\r\n" to the end of the replace-text, otherwise the newline's will be removed, making it one long continuous line.
