I guess this script should do it.

from Npp import notepad, editor, editor1, editor2, SCINTILLANOTIFICATION, NOTIFICATION

class VIEW_MONITOR:

    def __init__(self):
        self.monitor = {0: None, 1: None}
        self.enabled = False
        notepad.callback(self.on_bufferactivated, [NOTIFICATION.BUFFERACTIVATED])
        editor.callbackSync(self.on_updateui, [SCINTILLANOTIFICATION.UPDATEUI])


    def on_bufferactivated(self, args):
        self.monitor[notepad.getCurrentView()] = args['bufferID']
        self.enabled = self.monitor[0] == self.monitor[1]


    def on_updateui(self, args):
        if self.enabled and args['updated'] == 0x8:
            e1_current_line = editor1.lineFromPosition(editor1.getCurrentPos())
            e2_current_line = editor2.lineFromPosition(editor2.getCurrentPos())
            if e1_current_line != e2_current_line:
                if notepad.getCurrentView():
                    editor1.gotoLine(e2_current_line)
                else:
                    editor2.gotoLine(e1_current_line)

mon = VIEW_MONITOR()

Assuming that your forked version allows installing pythonscript
plugin, create a new script via pythonscript plugin menu, name it
startup.py and paste the content of the script into it. Save it, close it.
Via pythonscript menu Configuration… set Initialisation from
LAZY to ATSTARTUP. Done. Restart npp.

@Ekopalypse Good call on the forked version–it does not support python scripts, I switched to the official download. I also removed “and args[‘updated’] == 0x8” from the “on_updatedui()” function. It seems like an arg value of 0x8 means horizontal scrolling has changed.

Thank you for your hard work! This will make readability so much easier. If I can repay the favor somehow just let me know.

No problem and good to see you already improved it for yourself.

If I can repay the favor somehow just let me know.

No joke, if you would like to share your favorite recipe with me,
I would appreciate.
Cooking/grilling/baking is another hobby I like to do. :-)

You didn’t elaborate on the magic number of “8”…would have been appreciated.

Alan Kilborn

@Ekopalypse

or maybe the OP already explained the 8.

I found that with the script as written, the sync-up won’t happen until one of the cloned-doc views is adjusted horizontally, e.g. the horizontal scroll bar is moved. This is OK to me. I will keep this script close at hand for future need.

Ekopalypse

@Alan-Kilborn, sorry @jcg3675 is right, it is the value for horizontal scroll changes.

Hello @jcg3675, @ekopalypse, @alan-kilborn and All,

I found out a weird but minor bug related to the Smart Highlighting when a file is cloned in the secondary view. Of course, @ekopalypse, this post does not refer to your python script at all, ( script that I have not tested it yet, BTW ! )

To begin with, some hypotheses :

N++ version : v7.8.3
No extra plugin installed, just the 3 default ones
Options ticked in Preferences... > Highlighting > Smart Highlighting : Enable, Match whole word only and Highlight another view. All the other options un-ticked
Disable the multi-line tabs feature by un-ticking the option Preferences... > General > Tab Bar > Multi-line => 1 row of tabs, only !
The Horizontal splitter between primary and secondary is selected. If not, simply right-click on the splitter and choose the Rotate to left option
Default zoom is used, both, in primary and secondary view ( Ctrl + Numpad / )
No horizontal nor vertical synchronization of the two views. So, un-tick the options View > Synchronize Vertical Scrolling and View > Synchronize Horizontal Scrolling
For readability, enable the line numbers column, in Preferences... > Editing > Display line number

Now :

Open a new tab
Hit the Enter key to create 20 empty lines
Then , append 10 lines containing the string ABCDE ( so, from lines 21 to 30 )
End with 2 empty lines ( lines 31 and 32 )
Save it as Test.txt
Select the option View > Move/Clone Current Document > Clone to Other View => The cloned document Test.txt is located at bottom of screen
Move line 16 as the first line in the secondary view
Now, select the original Test.txt tab, on top of screen
In the same way, move line 16 as the first line of the primary view
Double-click on line 23 of the primary view => The ten lines ABCDE, in each view, are highlighted, as expected
Then, while keeping the mouse pointer over the primary view, scroll down , with the mouse wheel ( or with the vertical bar ) , until no text is present => Only the visible line(s) of the primary view is/are highlighted in the secondary view !
Now, scroll up, with the mouse wheel, until no text is present => In the same way, only the visible line(s) of the primary view is/are highlighted in the secondary view !

Remarks :

If, without changing the active top tab ( primary view ), we place the mouse pointer over the secondary view and scroll up/down, with the mouse wheel, nothing is changed in the primary view and the ten lines are always highlighted
If we stop and re-start Notepad++ with the Test.txt displayed in each view, this minor bug still occurs
I also noticed this behaviour, with the old N++ 7.2 version, which was the first release which included the Highlight another view option, regarding the Smart Highlighting feature !
Although not tested, I suppose that the recent v7.8.4 version does produce the same bug

Important :

Instead of cloning the file Test.txt, in the secondary view, let’s create a copy of the file Test.txt, named Copy.txt
Open this new file, in the secondary view, with the option View > Move/Clone Current Document > Move to Other View
This time, if we repeat the above steps, whatever the visible lines ABCDE, in the primary view, obtained by scrolling text up or down, the ten lines ABCDE of the identical file Copy.txt are always highlighted, in the secondary view, as expected !

Best Regards,

@guy038 said in Select the same line in both views of cloned document.:

this minor bug

Should you also do THIS with it?

Ekopalypse

I discovered something similar when using the new method multipleSelectAddNext.

If I use your test and having in the top view only two occurrences of the word ABCDE visible, placing the caret within the first visible word ABCDE and I run editor.multipleSelectAddNext(), it only selects the two visible lines.

The documentation states, that it does that for the current target. Now it might be, that either scintilla or npp set the visible lines as the current target automatically, or that this is a bug. Needs to be checked.

Hello, @jcg3675, @ekopalypse, @alan-kilborn and All,

So, with some delay, I created an issue on GitHub :

issue#7910

Cheers,

@Ekopalypse Well I am more of a microwave dinner and Ramen noodle kind of guy at the moment, being a college student and all :)

But I do have a suggestion–my family makes Lithuanian cracker stuffing a couple of times a year for the big holidays. My dad’s side has made it every year since they came to America in the 1910s.

The recipe that I linked is pretty accurate, but there are a few modifications:
Replace chopped giblets with diced turkey bacon bits
Replace saltine crackers with milk crackers

And that should do it. Let me know how it goes!

@jcg3675
Thank you very much and yes, there is time when a microwave becomes the best invention since sliced bread :-)

Let me know how it goes!

I sure will do.
