Multi selection and multi edit

Claudia Frank

Well I can understand as it is a critical component which can break npp I guess.
But if there is something I can do, like comparing source code to see which functions
have been modified etc., I would do it.

Cheers

Thanks for the script @Claudia-Frank! It works well.

It sounds like an updated Scintilla is what we need. Is there any timeline on how often the dev updates the Scintilla version used?

dail

The new version of Scintilla doesn’t really introduce anything that can’t be done currently with a plugin, it just makes it more convenient. Updates vary between a few months to a few years

I understand the caution updating Scintilla but it still seems like there are many advantages that could be taken with updating it more regularly. Don always takes care of updating it himself.

Hello Chandler Newby and All,

Presently, with current versions of N++, to get the SAME result, you need to perform the five steps below :

Place the cursor, JUST BEFORE the text to search for :
Perform the menu option Edit - Begin/End Select
Select your text ( either a character, a word or a several words string )
Perform the menu option Search - Select and Find Next or use the CTRL + F3 shortcut

IMPORTANT : you may run this command several times to get the Nth occurrence of your selected text

Perform, again, the menu option Edit - Begin/End Select

=> All the area, between the FIRST occurrence of the selected text, included, till the LAST occurrence found, included, is, then, selected

Et voilà !

Best Regards,

guy038

@Claudia-Frank : Thanks for your script. How need to change if i want to set the range of find and modfication : from line 10 to line 100, it would be best if we can select instead of line number input

Scott Sumner

@ng-khanh

The biggest issue with your desired change is how to specify the range of lines you want to limit it to functioning over. As you said, entering actual line numbers is not ideal (although that would work, and could easily be set in the “prompt” box along with the 0, 1, 2 choice).

How about the placement of two bookmarks, one on the first line and one on the last line? This presumes that you currently aren’t using bookmarks for something else when you want to invoke this functionality.

Claudia Frank

Bookmarks is nice because than it can be used with F2 to jump to.
Another, possible way, could be that only the visible area gets changed or
if you select the first and the last (by holding ctrl) and everything in between,
together with the selected once, get replaced.
Or we try to extend it so it does all of this.
So with a prompt like

0 = replace,  1 = before, 2 = afterwards
a = all, b = bookmarks, s = selected, v = visible,

So 0a would mean replace all occurrences and 1b would
be insert before selected word within bookmared lines etc…

Cheers

Claudia Frank

Below the modified script.
Some words to explain its functionality.
If you run the script you will be asked for some options,
namely the area which should be used and the mode what to do.

Mode is either

0=replace
1=insert before
2=insert after

Area is either

a=all lines
b=position enclosed by two bookmarks
s=position enclosed by two selected words
v=lines in the view which are currently visible

So if one defines 0a it means every occurrence of the selected word gets overwritten with the current word
If one chooses 1b then only the selected words within the bookmarks, which are needed to be set first, get modified by
inserting the typed chars before the words.
2v would mean add additional chars to the end of the selected words, but only for those who are currently visible.
Well, this is not exactly true, it means that text gets added to every selected item from first visible line
including the last visible line.
Example:
Line 1-20 is visible
Line 21-30 is hidden
Line 31-40 is visible
Line 41-… exist but is out of view aka non-visible

If one selects area v then the words in the lines 21-30 get considered(modified/replaced) too.

Area s can only be used if settings->preferences->editing->Multi-Editing has been enabled.

Last but not least, there is a variable find_flag which is set to WHOLEWORD per default.
If one once to have no restriction set it to 0 or any other value stated in the comment.

That’s it.

Cheers
Claudia

Hi, Claudia,

Until your recent script, I didn’t interfere, in that discussion, because I thought that a simple S/R, in regex mode, was enough to get the same behaviour. Indeed :

For Replacement : SEARCH = "Searched word" and REPLACEMENT = "Replacement word"
For Insertion before : SEARCH = "Searched word" and REPLACEMENT = "Added word${0}"
For Insertion after : SEARCH = "Searched word" and REPLACEMENT = "${0}Added word"

But, your last script, with the different area options, shows, clearly, the advantages of a script ;-)) Your script should satisfy everyone !

However, I just noticed a minor bug : if you start the script by mistake, and that you want to stop it, the Cancel button does NOT work. So, the only choice is the Yes button !

Cheers,

guy038

BTW, if your file is quite important, it can take some seconds, before all the matches are highlighted !!

Vasile Caraus

@dail

agree

Claudia Frank

@guy038

there is no need for a stop routine as it is a per one time execution script - no callbacks.
You run the script and all it does is to select the different instances of the selected word.
Once everything has been selected it finishes instantly.

You are right, it hasn’t optimized for speed but I think it doesn’t make sense to edit
a huge file and use this little helper to replace all occurrences of a string. Npps
builtin feature is much faster in this way.

Cheers
Claudia

@Claudia-Frank

I think what @guy038 meant was, what if you start the script running, get the prompt dialog box on the screen, and then change your mind and decide you don’t want to do what you started after all.

Claudia Frank

@Scott-Sumner

ahh - ok - yes correct - but just press ok and move cursor.
Nothing changed.

finally I understand - the cancel button !! phew – need a cup of coffee!

kpym

I want to advocate too for CTRL+D sublime-like build-in shortcut.
This is the most useful way to use multi-cursors :

add next identical
skip next identical
select all identicals

Alan Kilborn

@kpym

So maybe on the surface this seems different, but this is really just a Find and Replace operation, for which Notepad++ already has a good solution for. Here’s a comparision:

your ctrl+d <–> N++'s press ctrl+h, fill in replace field
your add/skip next identical <–> N++ either “Find Next” or “Replace”
your select all identicals <–> N++ “Replace All”
your “whatever action you would do on what is multiselected…” <–> N++'s nothing to do, it’s already done!

bitagoras

@Alan Kilborn
What you irgnore in your comment is the fact that Ctrl+D function is mainly used to quickly clone the cursor at positions of identical strings and not neccessarily to replace the selected. Once you have multiple cursors, you can move them and do much more things than just renaming. I uploaded a gif animation that shows what I mean:

https://gifyu.com/image/TaVW

It’s really magic what you can to with it and safes you a lot of time with a minimum of commands to remember. It is very intuitive and in most of the cases faster than search / replace or macro recording. Sometimes I use VS Code in parallel with Notepad++ only because of this function.

What is missing to make full use of this kind of multi editing:

Ctrl+D (or another shortcut) to clone the cursor at similar occurences of the current word or selection.
Multiple cursors should stay persistent until escape is pressed (as in the plugin “better multiselection”).
Ctrl+mouseclick should not only add but also remove one cursor (when Ctrl+D has produced an unwanted cursor).
Every cursor should have an indiviual clipboard.

Scott Sumner

@bitagoras

This kind of functionality really has nothing to do with Notepad++ itself, but rather is Scintilla-related. Scintilla in Notepad++ is known to be very outdated. Would upgrading Scintilla to the latest version provide such functionality? I don’t know, but since remaining current with Scintilla doesn’t seem to be a priority of Notepad++ developers, it probably isn’t worth much discussion here. :-(

bitagoras

I think with a little bit of programming it could be possible with scintilla but it is not a standard feature that can just be activated.

But you say the Notepad++ developers plan to replace Scintilla? Do you know any details? I haven’t seen any discussion here on this. I wonder, if this wouldn’t be just another new editor but not Notepad++ any more.
