      One of the features I’ve been anxiously awaiting in the next Scintilla update was being able to ‘find’ something, and then finding again so I could get several occurrences in a multi-select status. I downloaded the minimalist version of 7.7 but there’s nothing in the edit or find menu that exposes that capability and I don’t see anything in the shortcut mapper list either. Am I not seeing something? Is this possible with a python script now? I think the Scintilla command I’m looking for is IDM_SELECTIONADDNEXT or 2688. Cntrl-Shift-D is the default key combo in SciTe that I’m trying to get in NPP. I’ve used @Claudia-Frank 's script from here but I was hoping to easily go one ‘find’ at a time w/o the dialog.

        See one of the sub-points of this thread…meaning that you can currently do it with LuaScript.

        Pythonscript will need to be updated to include the functionality, and it just hasn’t been done yet.

        Of course, Notepad++ itself could be updated as well to do it…

          Thanks Alan, I need to get over to plug-in development more often. Hopefully the Python maintainers are able to get something out soon. Or maybe @dail converted me to Lua!

            @dail , @cipher-1024 , @Alan-Kilborn and all

            I’ve tried to get the benefit of SCI_MULTIPLESELECTADDNEXT and SCI_MULTIPLESELECTADDEACH following the advice of @dail in this already mentioned thread, but I wasn’t successful.

            I’ve set up the little script of @dail as a LUA Script plugin startup script and restarted Notepad++. I can confirm that after that there was a new entry in the submenu of the LUA Script plugin showing the expected text and keyboard shortcut. I selected a word by double-clicking on it or pressing CTRL+Right.The word became the main selection and all other instances of it in the whole text became marked. Then I pressed the keyboard shortcut assigned to the new Scintilla features, but I got no multiple cursors, nothing happened.

            Of course I’ve used Notepad++ v7.7 and the latest version of the LUA Script plugin, i.e. v0.9 from the provided download link.

            I’ve tried something similar using the NppExec plugin with the bare numeric message codes for SCI_MULTIPLESELECTADDNEXT (2688) and SCI_MULTIPLESELECTADDEACH (2689) but it didn’t work either.

            Has anybody some advice whether there are some Notepad++ settings that might interfere with SCI_MULTIPLESELECTADDNEXT and SCI_MULTIPLESELECTADDEACH to prevent them from working properly?

              you need to set target start and end before calling one of the new functions.

                Thank you, that helped! I’ve used the NppExecplugin and the sequence:

                1. Select a word.
                2. Send SCI_TARGETWHOLEDOCUMENT (message code 2690) to set Scintilla’s target.
                3. Send SCI_MULTIPLESELECTADDEACH (message code 2689) to multi-edit all instances of the word.

                  if different findoption should be used you can add a step 2a. SCI_SETSEARCHFLAGS

                    Thanks for that additional hint, much appreciated!

                    Here is my complete NppExec script:

                    sci_sendmsg SCI_GETSELECTIONEMPTY
                    
                    if $(MSG_RESULT) == 1 then
                      sci_sendmsg SCI_WORDRIGHTEXTEND
                    endif
                    
                    sci_sendmsg SCI_SETSEARCHFLAGS SCFIND_WHOLEWORD 
                    
                    sci_sendmsg 2690
                    sci_sendmsg 2689
                    

                    It automatically selects the word right from the cursor but only if there is no active selection.

                      @dinkumoil - nice one, thanks for sharing.
                      One question, as I don’t have NppExec currently installed,
                      is it really needed to do SCI_WORDRIGHTEXTEND?

                      From the docs it states If the current selection is empty then select word around caret

                        According to my tests - yes.

                        If the SCI_WORDRIGHTEXTEND part is removed from the script, executing it (without an active selection) selects the word right from the cursor and marks all other instances of the word in the whole text but there are no multiple cursors.

                            It automatically selects the word right from the cursor but only if there is no active selection.

                            I tried the NppExec script and I found that if I run it without a selection but with the caret inside or at the start of a word, it will select from the caret to the right to just before the start of the next word, and then fail to give multiple carets; example with caret sitting on second s of highlighted sci_sendmsg:

                            Imgur

                            Starting with an entire word preselected (here the 2nd sci_sendmsg in the file) however works just fine:

                            Imgur

                            Perhaps I miss something about the case where there is no selected text first…

                              Improved version of my NppExec script:

                              sci_sendmsg SCI_GETSELECTIONEMPTY
                              
                              if $(MSG_RESULT) == 1 then
                                sci_sendmsg SCI_GETCURRENTPOS
                                set local $(CurPos) ~ $(MSG_RESULT)
                              
                                sci_sendmsg SCI_WORDSTARTPOSITION $(CurPos) 1
                              
                                if $(MSG_RESULT) != $(CurPos) then
                                  sci_sendmsg SCI_WORDLEFT
                                endif
                              
                                sci_sendmsg SCI_WORDRIGHTEXTEND
                              endif
                              
                              sci_sendmsg SCI_SETSEARCHFLAGS SCFIND_WHOLEWORD 
                              
                              sci_sendmsg 2690
                              sci_sendmsg 2689
                              

                              If the cursor is placed in the middle of a word without an active selection when executing the script, it is moved to the next word boundary to its left before selecting the word to the right of its new position, i.e. the word in whose mid it was placed before.

                                  It works at my site. Did you restart Notepad++ after updating the script?

                                    No, but I didn’t “save” it, I was just running it as a NppExec temporary script…

                                      Totally just for fun, I managed to replicate the functionality with Pythonscript in its current (1.4) form:

                                      import ctypes
                                      from ctypes.wintypes import HWND
                                      from ctypes import byref, wintypes, Structure, sizeof

                                        Hmm, I found a strange pitfall with my code.

                                        I use for testing the same snippet of source code @dail used in his posting in the other thread:

                                        static std::string getWordAt(GUI::ScintillaWindow *window, int pos) {
                                          int word_start = window->Call(SCI_WORDSTARTPOSITION, pos, true);
                                          int word_end = window->Call(SCI_WORDENDPOSITION, pos, true);
                                          return getRange(window, word_start, word_end);
                                        }
                                        

                                        If I place the cursor before the word pos near the end of line 1 and press my keyboard shortcut everything works fine. If I do the same with placeing it before the word int near the end of line 1, the script selects the word int and the following space character and nothing more happens. It looks like the sci_sendmsg SCI_WORDRIGHTEXTEND gives a wrong result.

                                        I will try to figure out what’s going on…

                                        EDIT: It’s because int is followed by a space character and pos by opening parenthesis. This would make this feature nearly useless. Gonna do further investigations…

                                          Yea, if you’ll take note, I had an intentional big amount of spaces to the right of the word I had my caret in for my testing. :)

                                            Does your Python script work as intended or is it a problem with the algorithm used?
