• SCI_MULTIPLESELECTADDNEXT adds the next occurrence of the main selection within the target to the set of selections as main. If the current selection is empty then select word around caret.

• SCI_MULTIPLESELECTADDEACH is similar to SCI_MULTIPLESELECTADDNEXT but adds multiple occurrences instead of just one.

For me, it was unnecessary to call SCI_TARGETWHOLEDOCUMENT, so, for selecting all instances of the word at once, you could just call SCI_MULTIPLESELECTADDNEXT followed by SCI_MULTIPLESELECTADDEACH:

// selects all instances of the selected word (or the word around the caret)
sci_sendmsg 2688 // SCI_MULTIPLESELECTADDNEXT
sci_sendmsg 2689 // SCI_MULTIPLESELECTADDEACH

…which has the same effect of simply calling SCI_MULTIPLESELECTADDEACH twice:

// selects all instances of the selected word (or the word around the caret)
sci_sendmsg 2689 // SCI_MULTIPLESELECTADDEACH
sci_sendmsg 2689 // SCI_MULTIPLESELECTADDEACH

Or, instead of blindly calling it twice, you could check if something is already selected with SCI_GETSELECTIONEMPTY (as used on other comments) and then call it only once:

// selects all instances of the selected word (or the word around the caret)
sci_sendmsg SCI_GETSELECTIONEMPTY
if $(MSG_RESULT) == 1 then
  sci_sendmsg 2688 // SCI_MULTIPLESELECTADDNEXT
endif

sci_sendmsg 2689 // SCI_MULTIPLESELECTADDEACH

PS: It would be really nice to have both commands (SCI_MULTIPLESELECTADDNEXT and SCI_MULTIPLESELECTADDEACH) available for hotkeys in “Settings” > “Shortcut Mapper” > “Scintilla commands”.

editor.setMultipleSelection(True) # in case not enabled in the Preferences

I tried installing NppExec on the 7.7 minimalist install…and trying out the script…but it would only select the current word and never go into multiedit mode

Multi-editing is disabled in a clean install or a portable install:

Did you go into the preferences and enable it like this?:

Alternatively, this can be added at the top of the NppExec script, to turn multi-selection ability ON:

sci_sendmsg 2563 1

Here’s where the 2563 comes from, in the Scintilla interface file:

# Set whether multiple selections can be made
set void SetMultipleSelection=2563(bool multipleSelection,)

trying out @dinkumoil 's script but it would only select the current word and never go into multiedit mode.

I guess you only tried the first or second version of the script. The final one and the shortened version of @Ekopalypse some postings above should work.

Out of curiosity I tried installing NppExec on the 7.7 minimalist install and trying out @dinkumoil 's script but it would only select the current word and never go into multiedit mode. (7.7 32bit, NppExec 0.6RC3). There are no errors in the console. I don’t know if the minimalist version and my older, installed version are conflicting in some way, but I couldn’t get the script to work.

@Alan-Kilborn , thanks for the python script, unfortunately I’m still on 1.0.8 so I haven’t tried it out yet. But once I’m back to being current, I will.

My job is being inconvenient and making me do stuff, so I need to sit tight on upgrading for a bit until I have time to iron out any old plugin issues that I may run into after the upgrading. Thank you one and all. This is a great community.

I admit that my enthusiasm is a bit excessive ! Just because I’m rather an old guy, which knew MS-DOS 5.0, WinWord 6 and Excel 5 and, even, some older goodies. So, I’m a little overwhelmed to see all these new powerful features ;-))

By the way, I’m no longer surprised to create rectangular selections, over, let say, 50,000 lines , with N++, for years now ! Quite similar, except that all the cursors are aligned ;-))

Cheers,

guy038

aahhhhh - I constantly forget about using it. :-)
Yes, it works without but as the syntax defines it, it should be used, imho.
Who knows what a future update will do.

What do you think?

Except the missing endif ;) - nice catch, it works!

Seems like SCI_MULTIPLESELECTADDEACH needs an active selection and SCI_MULTIPLESELECTADDNEXT doesn’t.

EDIT: Seems like even the endif is not necessary, I apologize. ;)

sci_sendmsg SCI_SETSEARCHFLAGS SCFIND_WHOLEWORD
sci_sendmsg 2690  // SCI_TARGETWHOLEDOCUMENT

sci_sendmsg SCI_GETSELECTIONEMPTY
if $(MSG_RESULT) == 1 then
  sci_sendmsg 2688  // SCI_MULTIPLESELECTADDNEXT
 
sci_sendmsg 2689  // SCI_MULTIPLESELECTADDEACH

What do you think?

This is multi-selection !!!

Yes. But maybe I am not understanding the fascination. As the OP mentioned in the first posting in this thread, there’s been “workaround” ways (see the link in that first posting) to achieve this type of multiselection for a long time…and all of the above in THIS thread is still workaround.

What is really needed to make this complete is a good interface within Notepad++ itself (no scripting plugins). Then, when someone posts to the Community “I can match the text I need by doing a regex-find, but how can I copy that text to a new document?”, we can finally give them a good answer. And by good I mean one that doesn’t start out with “Install a scripting plugin…”. Not that there’s anything wrong with scripting plugins, but it is just too cumbersome for someone that has a single need.

As @dinkumoil and, probably, most of you, I’ve just studied the two new Scintilla commands SCI_MULTIPLESELECTADDNEXT and SCI_MULTIPLESELECTADDEACH ! Really impressive ;-))

• Install, of course, the last v0.9 (32 bits ) version of LuaScript, on the last v7.7 version of N++

• Modify, like me, the startup.lua file, as below :

-- Startup script
-- Changes will take effect once Notepad++ is restarted

npp.AddShortcut("Selection Add Next", "Ctrl+F12", function()
    editor:MultipleSelectAddNext()
end)

npp.AddShortcut("Selection Add Each", "Shift+Ctrl+F12", function()
    editor:MultipleSelectAddEach()
end)

-- And affected the 'ALT + F12' shortcut to the 'Plugins > LuaScript > Execute Current File' option
--                   ---------                   ------------------------------------------

• Affect, as noticed, the Alt + F12 shortcut to the menu command Plugins > LuaScript > Execute Current File

• Then, paste this simple Lua file, below, in a new tab

-- editor:SetTargetRange(69, 140)  -- TARGET, from START of line 9 to END of line 15


-- And... execute the MAGIC command !

editor:MultipleSelectAddEach()

-- LAST TeSt line

• Save it with name Test.lua

As you can see, the only uncommented command is editor:MultipleSelectAddEach()

• Now re-start N++ and re-open this Test.lua, if necessary

• Unset the Word wrap feature ( View > Word wrap )

• Zoom out till the maximum ( Ctrl + Num+ )

• Click on the vertical bar to scroll down, in order that the line 8 is on top of the windows text

=> So, you should see, approximatively, from line 8 to line 21 ( with the default Courier New font )

• Now, do a normal selection of the string t.*t, on line 10

• Finally, run the command Plugins > LuaScript > Execute Current File or hit on Alt + F12 ( my shortcut )

=> You should see that the word test in any case, as well as the forms T.*T and t.*t are selected from line 8 till line 20, only, as well as 13 cursors appear, on the right of each selection !

This means that, by default, if, either, NO flags were previously set and NO target was previously defined, the lua command editor:MultipleSelectAddEach() seems to select all matches of the string t.*t, in regular expression mode, without the Match case and Match whole word only options, in all the visible lines of the current screen !?

Of course, if you uncomment the line editor:TargetWholeDocument() and redo the same actions as above, ending with the Plugins > LuaScript > Execute Current File command, this time, a lot of selections, matching the regex criteria t.*t, have appeared, in the whole document

=> It’s easy to see that the search is performed in a regex way as many lines, outside the test zone, with variable length, have been also selected !

Now :

• Comment, again, the editor:TargetWholeDocument() line

• Uncomment the line editor:SetTargetRange(69, 140) -- TARGET, from START of line 9 to END of line 15

• Zoom out till the maximum ( Ctrl + Num+ )

• Select the string t.*t, in line 10

• Click on the vertical bar to scroll down till the end of the script

• Run the command Plugins > LuaScript > Execute Current File

=> This time, you should see the line 9 on top of the view and, both, the t.*t and test, in any case, selected from line 9 to line 15

Note : for the editor:TargetFromSelection() command, refer to the explanations in comments !

Now :

• Comment the line editor:SetTargetRange(69, 140) -- TARGET, from START of line 9 to END of line 15

• Uncomment the editor:TargetWholeDocument() line

• Uncomment the editor.SearchFlags = 0 line

• Select the string t.*t, in line 10

• Run the command Plugins > LuaScript > Execute Current File

=> This time, the ranges, matching the string t.*t, in any case, are selected, only, ( from lines 5 to 10 ) Logic, as the search is perfomed in a normal insensitive way !

Then :

• Move the cursor at beginning of line 17, without selecting anything

• Run the command Plugins > LuaScript > Execute Current File

=> The word TEST is now selected

• Run, again, the same command Plugins > LuaScript > Execute Current File

=> As expected, this time, all the words TEST, in any case, are selected, included the last line, with word TeSt

Now :

• Comment the editor.SearchFlags = 0 line

• Uncomment the editor.SearchFlags = 4 | 2 ...........

• Double-click on the word test, in line 22

• Run the command Plugins > LuaScript > Execute Current File

=> Only the true words test, in lower-case, are selected ( in lines 4, 14, 18 and 22 )

Finally :

• Comment the editor.SearchFlags = 4 | 2 ...........

• **Uncomment the editor.SearchFlags = SCFIND_REGEXP | SCFIND_MATCHCASE

• Select all line 5 contents ( T.*T )

• Run the command Plugins > LuaScript > Execute Current File

=> As expected, the longest ranges of text of lines, beginning and ending with the upper-case letter T, are selected, even embedded in other ranges of characters !

Best Regards,

guy038

P.S. : A last interesting test :

• First, create this tiny lua script, below, which you’ll name Test_2.lua :

editor.SearchFlags = 0

editor:TargetWholeDocument()

print ("Parameters SET !")

• Then, create a dummy file, containing, 100 times, the sample text, below :

This a test of MULTI-selections
test of MULTI-selections
1234567890This a test of MULTI-selections
t.*t										This a test of MULTI-selections
                                                        This a test of MULTI-selections
This atestof MULTI-selections
This a TeSt of MULTI-selections 1234567890
This a test
This a test of MULTI-selections
test

=> So, you get a 1,000 lines text, each containing the word Test, in various cases

• Save it in your current directory

• Move back to the beginning of this test file ( Ctrl + Home )

• Execute the menu command Plugins > LuaScript > Show console

• In the opened lua console, write the command winfile.dofile("Test_2.lua") and valid with the Enter key

=> The message Parameters SET ! confirms the good execution of the script

• Then double-click on the word test, in line 1 of current file

• Finally, run the menu command Plugins > LuaScript > Selection Add Each

Waaaaouh ! Immediately, 1,000 words Test are selected, at once ! And, after hitting the Right arrow key, 1,000 cursors are visible and available for adding/deleting characters ;-)))

This is multi-selection !!!

npp.AddShortcut("Selection Add Next", "Ctrl+D", function()
    -- From SciTEBase.cxx
    local flags = SCFIND_MATCHCASE -- can use 0
    editor:SetTargetRange(0, editor.TextLength)
    editor.SearchFlags = flags

    -- From Editor.cxx
    if editor.SelectionEmpty or not editor.MultipleSelection then
        local startWord = editor:WordStartPosition(editor.CurrentPos, true)
        local endWord = editor:WordEndPosition(startWord, true)
        editor:SetSelection(startWord, endWord)
    else
        local i = editor.MainSelection
        local s = editor:textrange(editor.SelectionNStart[i], editor.SelectionNEnd[i])
        local searchRanges = {{editor.SelectionNEnd[i], editor.TargetEnd}, {editor.TargetStart, editor.SelectionNStart[i]}}
        for _, range in pairs(searchRanges) do
            editor:SetTargetRange(range[1], range[2])
            if editor:SearchInTarget(s) ~= -1 then
                editor:AddSelection(editor.TargetStart, editor.TargetEnd)
                editor:ScrollRange(editor.TargetStart, editor.TargetEnd)
                break
            end
        end
    end
end)

In theory this should be the exact functionality (well, very close at least) that SCI_MULTIPLESELECTADDNEXT provides. Should be translatable to PythonScript or NppExec as this above code was working with Scintilla v3.5.6

I was hoping to easily go one ‘find’ at a time

I guess we ignored that part of the request. :)

(and working) version of the script:

CONFIRMED! :)

Here is the updated (and working) version of the 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_WORDRIGHTENDEXTEND
endif

sci_sendmsg SCI_SETSEARCHFLAGS SCFIND_WHOLEWORD 

sci_sendmsg 2690
sci_sendmsg 2689

Not sure if I understand the q… The PS doesn’t use the “word-right-extend” stuff, which seems to be where the trouble lies with the NppExec scripts presented to this point…

I didn’t do exhaustive testing on the PS, but yea, seems to work as intended.

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

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. :)

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…

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…

I tried the NppExec script just above and had the same result as the earlier NppExec script when no selection before running…

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

Oh, I’ve posted before I could even see your posting…
