      Hello, @zweafw, @mark-olson and All,

      I think that a native N++ solution is possible !

      Let’s start with this INPUT text, below :

      This is a| 43 points
      random | 82 points
      Text to | 82 points
      See how it works | 153 points
      

      With the following regex S/R :

      search (?x-s) ^ .+ \| \x20 ( .+ )

      Replace \1\t$0

      We get the temporary text :

      43 points	This is a| 43 points
      82 points	random | 82 points
      82 points	Text to | 82 points
      153 points	See how it works | 153 points
      

      Now, run the Edit > Line Operations > Sort Lines As Integers Descending option

      We obtain this sorted file :

      153 points	See how it works | 153 points
      82 points	random | 82 points
      82 points	Text to | 82 points
      43 points	This is a| 43 points
      

      Finally, with this last regex S/R :

      SEARCH ^.+\t

      REPLACE Leave EMPTY

      Here is your expected OUTPUT text :

      See how it works | 153 points
      random | 82 points
      Text to | 82 points
      This is a| 43 points
      

      Best Regards,

        I should know better than to ever count out our resident regex wizard…

          @Mark-Olson,
          I was thinking of taking a crack at it late this morning myself, but realized quickly…I’m not up to that kind of manipulation yet. :)

            I’m new on Notepad++ and I want to know how can sort number from largest to smallest.

            click on edit --> line operation–> sort lines as Integer descending

              Yes, that would work in the specific case where the line starts with integers.
              But if the line doesn’t start with integers, as in the user’s example data, it will not work. That’s why we went to all this trouble to pre-process the text.

                I’m contemplating turning this script into a general-purpose thing to sort lines by the numeric or text value of any regex search result in that line.

                Apologies to Mark for a possible upstaging, but I took this idea and ran with it, producing the following script called SortLinesWithRegexGroup1AsSortKey.py:

                Let’s walk thru using it on @guy038’s data:

                This is a| 43 points
                random | 82 points
                Text to | 82 points
                See how it works | 153 points
                

                Put those lines in a tab and select them and run the script.

                You get prompted:

                8707f9ef-328c-4b5c-a99c-5cf11caf8911-image.png

                Enter \| (\d+) points as this regex matches the desired sort key and places it in capture group 1:

                1aa0e2ee-32ec-4ae8-8b3a-90a4092aca6c-image.png

                and press OK/Enter.

                The next prompt is:

                f73dc53c-a24c-4dfd-b078-25969d1af90f-image.png

                (Yep, my ever-so-cheesy-UI)

                Since we desire a high-to-low sort, “tick” the box for a Descending sort:

                c668f57c-5979-456b-808b-d27898c61d2f-image.png

                and press OK/Enter (accepting all the other “defaults” without needing to “tick” their boxes).

                Then the originally selected lines change to this data, the result of the specified sort:

                See how it works | 153 points
                random | 82 points
                Text to | 82 points
                This is a| 43 points

                Moderator EDIT (2024-Jan-14): The author of the script has found a fairly serious bug with the code published here for those that use Mac-style or Linux-style line-endings in their files. The logic for Mac and Linux was reversed, and thus if the script was used on one type of file, the line-endings for the opposite type of file could end up in the file after the script is run. This is insidious, because unless one works with visible line-endings turned on, this is likely not noticed. Some detail on the problem is HERE. The script above has been corrected per that instruction.

                  Awesome! I don’t mind being upstaged at all, and it has all the features I would have wanted. I’ll play around with this and see if I can come up with improvements.

                      OK, I’ve added two new options: lowercase culture-insensitive (Python can do that, it’s just rather obscure) and sorting unmatched lines to bottom.

                      The text:

                      foo: tone bar: 27.1
                      foo: bLue bar: 241.3
                      foo: taco bar: 66.5
                      foo: basst bar: 281.7
                      foo: öyster bar: 144.0
                      foo: oyster bar: 164.1
                      foo: Spb bar: 102.1
                      foo: blüe bar: 203.2
                      foo: spä bar: 121.2
                      foo: spb bar: 84.2
                      foo: blve bar: 183.2
                      foo: blue bar: 222.2
                      foo: baßk bar: 261.3
                      foo: täco bar: 47.3
                      

                      Sorting unmatched lines to bottom (regex bar: (\d\d)\D, all other options default). Note that the lines with a 3-digit number all stay in the same order.

                      foo: tone bar: 27.1
                      foo: täco bar: 47.3
                      foo: taco bar: 66.5
                      foo: spb bar: 84.2
                      foo: bLue bar: 241.3
                      foo: basst bar: 281.7
                      foo: öyster bar: 144.0
                      foo: oyster bar: 164.1
                      foo: Spb bar: 102.1
                      foo: blüe bar: 203.2
                      foo: spä bar: 121.2
                      foo: blve bar: 183.2
                      foo: blue bar: 222.2
                      foo: baßk bar: 261.3
                      

                      Ignorecase culture-sensitive (regex foo: (\w+), all other options default)

                      foo: basst bar: 281.7
                      foo: baßk bar: 261.3
                      foo: bLue bar: 241.3
                      foo: blue bar: 222.2
                      foo: blüe bar: 203.2
                      foo: blve bar: 183.2
                      foo: oyster bar: 164.1
                      foo: öyster bar: 144.0
                      foo: spä bar: 121.2
                      foo: Spb bar: 102.1
                      foo: spb bar: 84.2
                      foo: taco bar: 66.5
                      foo: täco bar: 47.3
                      foo: tone bar: 27.1

                      Maybe some day I’ll come up with a way to sort by arbitrary rearrangements of multiple groups like \2\L\1\E, but this is fine for now.

                      EDIT: I suppose that sorting by \2\L\1\E could be accomplished by doing the find/replace with \2\L\1\E🤷🤷$0 as replacement, then sort however you want, then find/replace ^.*🤷🤷 with nothing.

                      Moderator EDIT (2024-Jan-14): The author of the script has found a fairly serious bug with the code published here for those that use Mac-style or Linux-style line-endings in their files. The logic for Mac and Linux was reversed, and thus if the script was used on one type of file, the line-endings for the opposite type of file could end up in the file after the script is run. This is insidious, because unless one works with visible line-endings turned on, this is likely not noticed. Some detail on the problem is HERE. The script above has been corrected per that instruction.

                        One thing I didn’t get around to doing in the script was making it easier on a user to specify a “decimal” key.

                        It probably would have been simpler for the user to specify a regex such as key(DECIMAL) rather than, e.g., key([-+]?[0-9]*\.?[0-9]+).

                        The script code could scan the user supplied regex for “DECIMAL” and replace with the somewhat hard-to-remember regex.

                        See HERE for the origins of that decimal-number regex.

                          Yep, good idea. I just added

                          NUMBER_RE = r'([-+]?[0-9]*\.?[0-9]+(?:[eE][-+]?\d+)?)'
                          INT_RE = r'([+-]?[0-9]+)'
                          

                          and user_regex_with_group_1.replace('(INT)', INT_RE).replace('(DECIMAL)', NUMBER_RE) after the regex is assigned but before it’s used.

                          It’s easy to get the basic structure of integer and decimal regexes, but there are way too many edge cases that are too easily forgotten.

                            Moderator EDIT (2024-Jan-14): The author of the script has found a fairly serious bug with the code published here for those that use Mac-style or Linux-style line-endings in their files. The logic for Mac and Linux was reversed, and thus if the script was used on one type of file, the line-endings for the opposite type of file could end up in the file after the script is run. This is insidious, because unless one works with visible line-endings turned on, this is likely not noticed. Some detail on the problem is HERE. The script above has been corrected per that instruction.

                              I discovered that my previous implementation of normalized case-insensitive text wasn’t quite right.

                              I can’t edit my last post, but the function ignorecase_culture_invariant should be replaced with this:

                              def ignorecase_culture_invariant(x):
                                  return unicodedata.normalize('NFD', x.upper())
                              

                              The previous implementation (using x.lower()) doesn’t work for German ß, and there are probably some other places where it fails.

                                Well, I said I would wait to post again until I had a significant improvement, and I believe I do.

                                I have now updated the script so it can sort multi-line blocks, for example, sorting a bunch of multi-line XML elements by some attribute.

                                Normally the only way to sort multi-line blocks is to do the following:

                                1. use a regex that replaces all the newlines in each block with some delimiter that is not present in the file while preserving newlines outside the block.
                                2. Sort the lines of the document using the above script or one of the built-in sorts
                                3. replace the delimiter with newlines.

                                This process is annoying, so I decided to automate it.

                                Behold!

                                  @Mark-Olson said in How i can sort number from largest to smallest on notepad++:

                                  (?-si)^def\h+(\w+)\s*([\w:\s,]+?)\s*(?:->[^:]+)?:(?:.+$|\h*\R(?:\x20+.*\R?)+)

                                  I see that you use \h, \s and \x20 for a space in one and the same regex. Is there a deeper reason for that? Or is it didactic in that you want to point out that there are more possibilities for a space?

                                    Yes, there are reasons for all of those decisions:

                                    1. \h between def and the name of the function because they must be on the same line but (I believe) there can be arbitrary spacing between them
                                    2. \s in the region containing the arguments because the arguments can be separated by arbitrary whitespace
                                    3. \x20 because I’m assuming that the function is indented by spaces.

                                        If you’ve used a script in this thread, you might want to double check your copy of it for a bug I’ve discovered.
                                        Look to previous postings in this topic thread where the script has been changed – find the text moderator edit (2024-Jan-14).
                                        There’s a link there that describes the bug in more detail, and shows what needs to be changed in an old copy (or you can simply grab a copy of the current version).
