      @Ekopalypse Thanks, the “background mode” does the job (for now).

      @Alan-Kilborn I’ve submitted a bug report here.

        Hello, @matthew-au, @michael-Vincent, @ekopalypse and All,

        I fully understand the problem ! In order to get the Split Lines feature to work, here is my work-around :

        • Open the Settings > Preferences... > Editing > Vertical Edge Settings option

        • If the window contains several column numbers, delete all these numbers

        • Now, type in an unique column number where you want the lines to be splitted

        • Tick the Background mode option ( IMPORTANT )

        • If preferred, you can untick this option, immediately !

        • Now the Ctrl + I feature should be fucntional, as soon as a selection have been made, whatever the Background or Line mode is chosen ;-))

        • If you want, you may rewrite all your previous column numbers

        • But, beware that any subsequent Ctrl + I operation will refer to the unique number noticed while ticking the Background mode option !!

        Here is my debug info :

        Notepad++ v7.8.6   (32-bit)
        Build time : Apr 18 2020 - 22:32:17
        Path : D:\@@\786\notepad++.exe
        Admin mode : OFF
        Local Conf mode : ON
        OS Name : Microsoft Windows XP (32-bit) 
        OS Build : 2600.0
        Plugins : Explorer.dll mimeTools.dll NppConverter.dll NppExport.dll 
        

        Best Regards

            @guy038 but works only as long as you don’t restart npp, correct?

              Hi, @matthew-au, @michael-Vincent, @ekopalypse, @alan-kilborn and All,

              @ekopalypse, Ah yes ! As soon as I restarted Notepad++, it simply showed the two edge lines that I had previously set ( 30 and 60 )

              However, remember that, by default, if no vertical setting or several vertical settings are set, then the CTRL + I feature splits lines, roughly, to the windows text width !

              Cheers,

                Hello, @matthew-au, @michael-Vincent, @ekopalypse, @alan-kilborn and All,

                The last N++ v7.8.6 version now supports the new Vertical Multi-Edge lines feature. Unfortunately, as a consequence, this definitively breaks the native Split Lines feature ( Ctrl + I )

                A work-around has been found but needs to choose one column number only and tick once on the Background mode option ! But this prevent you from easily using multiple vertical lines, which is a pity :-(

                So, I imagined a regex S/R, that exactly simulates the N++ Split Lines feature ;-))

                Just one constraint : If your text contains some tabulation chars, you must run, first, the Edit > BLank Operations > TAB to Space option, in order to change any tab character with the appropriate number of space chars. Indeed, the regex S/R assumes that each character displayed takes the place of exactly one character. !

                The generic regex S/R, for any splitting column C is :

                SEARCH (?-s)^(?=.{C})(.{1,C-3}\x20|.{C-1})\K

                REPLACE \r\n    ( or \n if Unix files )

                So, let’s suppose that you want to split text, at column C = 80. In that case, the regex S/R must be changed as below :

                • SEARCH (?-s)^(?=.{80})(.{1,77}\x20|.{79})\K

                • REPLACE \r\n    ( or \n if Unix files )

                • Tick the Wrap around option

                • Select the Regular expression search mode

                • CLick on Replace All button, exclusively ( Do not use the Replace button ! )


                After numerous tests, I verified that the split texts are strictly identical :

                • Whatever the Split Lines option ( Ctrl + I ) or the Regex S/R is used

                • Whatever the In selection option is set or not, in the Replace dialog

                • Whatever the Line or Background mode is used, in Settings > Preferences... > Editing > Vertical Edge Settings

                • Whatever the View > Word wrap option is set or not

                • Whatever the View > Show Symbol > Show All Characters option is set or not

                • Whatever the current font used is a MonoSpace or a Proportional font, in the Style Configurator...

                In case of a proportional font, do not trust the visual vertical edge line, but rely on the real column, indicated in Settings > Preferences... > Editing > Vertical Edge Settings ! BTW, the Line mode is generally recommended for monospace fonts and the Background mode should be preferred for proportional fonts !


                As a test, we’ll simply use the License.txt file and split its contents at column 80 :

                • First of all, make sure that the single number 80 is shown in Settings > Preferences... > Editing > Vertical Edge Settings

                • Copy the License.txt file in two new tabs ( new 1 and new 2 )

                • In the new 1 file :

                  • Ctrl + A

                  • Ctrl + I ( Split Lines option )

                • In the new 2 file :

                  • Open the Replace dialog ( Ctrl + H )

                    • SEARCH (?-s)^(?=.{80})(.{1,77}\x20|.{79})\K

                    • REPLACE \r\n    ( or \n if Unix files )

                    • Tick the Wrap around option

                    • Select the Regular expression search mode

                    • Click on Replace All button, exclusively ( Do not use the Replace button ! )

                • Now, compare the two tabs with, for instance, the Compare plugin or with an external compare tool => The two tabs should be strictly identical ;-))

                Remark : Of course, this regex S/R supposed that the splitting vertical line was at position 80. So, adapt the generic regex, above, according to the real column needed !

                Best Regards,

                    Any reason for the capturing group usage?:

                      Hi, @alan-kilborn and All,

                      You’re perfectly right about it : No need of a capturing group for that purpose ! So, the generic search regex can be changed as below :

                      SEARCH (?-s)^(?=.{C})(?:.{1,C-3}\x20|.{C-1})\K

                      And the corresponding search regex for C = 80 is :

                      SEARCH (?-s)^(?=.{80})(?:.{1,77}\x20|.{79})\K

                      Indeed, although the maximum of characters, caught in group 1, not exceeds, either, C-2 or C-1 chars, the fact of using a non-capturing group should speed up the replacement process, in case of huge files !

                      Cheers,

                      guy038

                        Not sure this is worth a new thread … I used the following NppExec / Scintilla script to set the vertical edge column to the current column (super useful in my usage). It is now broken. Any recommendations for how to fix is appreciated. I did try what I thought was the obvious update and it didn’t work…

                        ::NPXEdgeColumSetToCurrent
                        NPP_CONSOLE ?
                        SCI_SENDMSG SCI_SETEDGECOLUMN $(CURRENT_COLUMN)

                          What version of Notepad++ - please post your debug info (menu ? => Debug Info…). I’ll assume you’re using the new 7.8.6 version as that is an easy fix. As of N++ 7.8.6, the vertical edge mode changed to multiedge by default so you can add multiple edges. You can try:

                          SCI_SENDMSG SCI_GETEDGEMODE
                          ================ READY ================
                          ECHO $(MSG_RESULT)
                          1
                          

                          to verify. I’m assuming you’ll get back “3” as in EDGE_MULTILINE. You can modify your script to be:

                          ::NPXEdgeColumSetToCurrent
                          NPP_CONSOLE ?
                          SCI_SENDMSG SCI_SETEDGEMODE EDGE_LINE
                          SCI_SENDMSG SCI_SETEDGECOLUMN $(CURRENT_COLUMN)
                          

                          Cheers.

                            Thanks, Michael.

                            I had downgraded to 7.8.5 because of this issue and was reluctant to jump back up, but I just did and your modification works a charm.

                            Appreciated.

                              Hello, @matthew-au, @i-neuw, @michael-Vincent, @ekopalypse, @alan-kilborn, @peterjones, @terry-r and All,

                              I revisited my previous posts of that discussion about the new Vertical Multi-Edge lines feature !

                              First, when I said :

                              A work-around has been found but needs to choose one column number only and tick once on the Background mode option !

                              I want to insist that the fact of ticking on the Background mode option, then unticking it, is needed to update the sole edge boundary value, displayed ! Even with the last 7.9.0 N++ version, this step is necessary !


                              Now, I did some additional tests, on, both, the final version of my regex and the native Split Lines N++ feature ( Ctrl + I ), using the license.txt file !

                              • Using my regex S/R method, to split the lines, we get the same result :

                                • Whatever the Line or Background mode is used, in Settings > Preferences... > Editing > Vertical Edge Settings

                                • Whatever the View > Word wrap option is set or not

                                • Whatever the View > Show Symbol > Show All Characters option is set or not

                                • Whatever the current font used is a MonoSpaced or a Proportional font, in the Style Configurator...

                              provided that you previously ran the Edit > BLank Operations > TAB to Space option if your file contains some TAB characters !


                              • Using the native Edit > Line Operations > Split Lines feature, we get the same result

                                • Whatever the Line or Background mode is used, in Settings > Preferences... > Editing > Vertical Edge Settings

                                • Whatever the View > Word wrap option is set or not


                              But, unlike what I said in my first post, the results of the Ctrl + I feature are totally different depending on whether :

                              • The View > Show Symbol > Show All Characters option is set or not

                              • The current font used is a Monospaced or a Proportional font, in the Style Configurator...


                              So, regarding my previous argumentation, my regex method and the native Split Lines N++ feature give the same results ONLY IF :

                              • A monospaced font is currently used

                              • The EOL symbol ( CRLF ) is not displayed

                              • The column number is superior to a minimum of about 15 for normal text. When I say “normal”, I refer, for instance, to the license.txt text, from line 28 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 till the end of file !

                              Note also that, with these hypotheses, the splitting operation of a selection of lines with, both, the regex S/R and the native Split Lines feature gives the same text contents !


                              IMPORTANT : My regex S/R is built in order to exactly replace the native Split Lines N++ feature, with the hypotheses above. But, of course, you may decide to not follow this rule and use, instead, a more simple search regex as, for instance :

                              SEARCH (?-s)^.{75,}?\K\x20+

                              REPLACE \r\n

                              which would split lines, roughly, after 80 characters

                              Best Regards,

                                Posting this in case it’s useful to anyone else. I worked around this issue using this plugin: dail8859/LuaScript: Notepad++ plugin for Lua scripting capabilities. Specifically, I added this code to my Lua startup script.

                                -- Lua function for Scintilla colors
                                local function RGB(red, green, blue)
                                    return red | green << 8 | blue << 16
                                end
                                
                                -- Teal color value same as default used in Notepad++
                                local COLOR_TEAL = RGB(128, 255, 255)
                                
                                -- Set line mode to EDGE_Line at 80 characters with teal color
                                npp.SendEditor(SCI_SETEDGEMODE, EDGE_LINE)
                                npp.SendEditor(SCI_SETEDGECOLUMN, 80)
                                npp.SendEditor(SCI_SETEDGECOLOUR, COLOR_TEAL)
                                

                                So, every time Notepad++ starts it resets the column marker. This has the same affect as if one were to toggle the “Background mode” setting.

                                  Thanks for your contribution.
                                  It is a Lua variation on @Michael-Vincent 's original NppExec solution.
                                  There hasn’t been a Pythonscript implementation, so I’ll add that now:

                                  editor.setEdgeMode(1)
                                  editor.setEdgeColumn(80)

                                        Since this is the older thread I will drop my two cents here.

                                        Notepad++ v7.8.6 introduced support for drawing multiple vertical lines (also called “edges”) inside of an editor window. But this new feature is not simply an extension of the old well-known single-edge-line feature, instead it is a completely new edge mode that replaced the old one. Unfortunately this broke the ability to word-wrap a document’s content at such an edge line (using the standard keyboard shortcut Ctrl+I).

                                        In the following I provide some scripts for the NppExec plugin to get back the old single-edge-line feature and being able to control it. Additionally I provide a fixed implementation of the related “word-wrap at single-edge-line” feature. That’s because I became aware that Notepad++'s internal implementation of this feature has two bugs:

                                        1. If the font size of the line numbers margin is set to a different value than the font size for documents, the “word-wrap at single-edge-line” code calculates a wrong wrapping position. This position has to be provided in pixels. To calculate this pixel value, a Scintilla function has to be called that calculates the width in pixels of a provided string from a provided text style. It seems like Notepad++'s internal code erroneously takes the text style of the line numbers margin font when calling this Scintilla function.

                                        2. To generate the template string for the pixel calculation mentioned above, it is necessary to query the set column number of the single-edge-line. Since column numbers in Scintilla are 0-based, the retrieved result has to be incremented by 1 to get the required length of the template string. It seems Notepad++'s internal code doesn’t do that because when word-wrapping a line that has a word boundary exactly at the single-edge-line it wraps this line at the beginning of that word instead at its end.

                                        Here are the scripts. Most of them could be assigned to a keyboard shortcut using Shortcut Mapper.

                                        Initialize Single-Edge-Line Mode

                                        ::SetSingleEdgeLine
                                        npp_console keep
                                        sci_sendmsg SCI_SETEDGECOLUMN 80
                                        sci_sendmsg SCI_SETEDGEMODE EDGE_LINE
                                        

                                        This script is intended to be used as a NppExec startup-script. It sets the single-edge-line column to column 80 and activates single-edge-line mode. It is able to override a multiple-edge-line or background-color-edge mode set in Notepad++ preferences dialog.

                                        Change Single-Edge-Line Column

                                        ::ConfigSingleEdgeLine
                                        npp_console keep
                                        sci_sendmsg SCI_GETEDGECOLUMN
                                        inputbox "Input edge column" : "Edge column" : $(MSG_RESULT)
                                        sci_sendmsg SCI_SETEDGECOLUMN $(INPUT)
                                        sci_sendmsg SCI_SETEDGEMODE EDGE_LINE
                                        

                                        This script opens an input box where users can change the single-edge-line column. The current column is shown as default value. When the user closes the box, the provided value is set as the new column and single-edge-line mode is activated.

                                        Turn on Single-Edge-Line Mode

                                        ::SingleEdgeLineOn
                                        npp_console keep
                                        sci_sendmsg SCI_SETEDGEMODE EDGE_LINE
                                        

                                        This script activates single-edge-line mode with its current settings.

                                        Turn on Multiple-Edge-Line Mode

                                        ::MultipleEdgeLinesOn
                                        npp_console keep
                                        sci_sendmsg SCI_SETEDGEMODE EDGE_MULTILINE
                                        

                                        This script activates multiple-edge-line mode with its current settings.

                                        Turn on Backgound-Color-Edge Mode

                                        ::BackgroundEdgeOn
                                        npp_console keep
                                        sci_sendmsg SCI_SETEDGEMODE EDGE_BACKGROUND
                                        

                                        This script activates background-color-edge mode with its current settings.

                                        Turn all Edges off

                                        ::EdgesOff
                                        npp_console keep
                                        sci_sendmsg SCI_SETEDGEMODE EDGE_NONE
                                        

                                        This script deactivates all edges.

                                        Word-Wrap Selected Text at Single-Edge-Line

                                        ::WrapSelectedLinesAtEdge
                                        npp_console keep
                                        
                                        set local $(EdgeModeSingleLine) ~ EDGE_LINE
                                        sci_sendmsg SCI_GETEDGEMODE
                                        
                                        if $(MSG_RESULT) != $(EdgeModeSingleLine) then
                                          set local $(LinePixelWidth) = 0
                                          goto :DoWrap
                                        endif
                                          
                                        sci_sendmsg SCI_GETEDGECOLUMN
                                        set local $(LineCharWidth) ~ $(MSG_RESULT) + 1
                                        
                                        set local $(TemplateStr) = W
                                        set local $(Cnt) = 2
                                        
                                        :ForLoopStart
                                          if $(Cnt) > $(LineCharWidth) goto :ForLoopEnd
                                          set local $(TemplateStr) = $(TemplateStr)W
                                          set local $(Cnt) ~ $(Cnt) + 1
                                        goto :ForLoopStart
                                        
                                        :ForLoopEnd
                                        sci_sendmsg SCI_TEXTWIDTH STYLE_DEFAULT "$(TemplateStr)"
                                        set local $(LinePixelWidth) = $(MSG_RESULT)
                                        
                                        :DoWrap
                                        sci_sendmsg SCI_TARGETFROMSELECTION
                                        sci_sendmsg SCI_LINESSPLIT $(LinePixelWidth)
                                        

                                        This script provides a fixed version of the “word-wrap at single-edge-line” feature. As the original one, it word-wraps at the right edit window border if edge mode is not set to single line. This script could be assigned to the Ctrl+I keyboard shortcut in order to replace the buggy built-in version of Notepad++.

                                          Hello, @dinkumoil and All,

                                          Very interesting insight and solutions about the new multiple vertical edges and word-wrapping at a specific position …and, incidentally, some good and short examples of the NppExec scripting language ;-))

                                          One question :

                                          When trying to find out a regex emulation of the Ctrl + I feature, some months ago, I realized that some mandatory conditions were needed to get the expected behaviour. Refer to the middle part of this post

                                          • So, did you verify the behaviour of your last ::WrapSelectedLinesAtEdge script in these three cases :

                                          • A proportional font is used instead of the monospaced one ?

                                          • The EOL symbol is displayed, with the View > Show Symbol > Show End of Line or View > Show Symbol > Show All Characters options

                                          • The current file contains some tabulation characters, as the number of pixels used by a TAB char is generally different from the space character !

                                          Indeed, the Ctrl + I behaviour, with a single edge, seemed broken when one of these cases occur !

                                          Best Regards,

                                          guy038

                                            Of course, I had not tested the behaviour of my WrapSelectedLinesAtEdge script in conjunction with a proportional font before you asked me because it makes no sense. ;-) Besides that, I’m sure it will not work .

                                            After testing I can say: I got the expected results.

                                            When using a proportional font, the edge line is still drawn as a straight vertical line and when moving the cursor up and down along this line, the Col : field of the status bar shows different values in every single line, depending on the crrent line’s content - obiously because the font is proportional and the characters have different widths. And when running my script, Scintilla does the word-wrap at totally wrong positions.

                                            An edge line simply makes no sense when using proportional fonts, thus my script makes no sense as well in this case. That’s the reason why I have not tested it and why I don’t care that it doesn’t work. :-)

                                            BTW: When I activated the proportional font in style configurator, Notepad++ immediately turned off the single-edge-line.
