what about using a hidden scintilla instance?

That also sounds “messy” (or “involved”) but if you have some snippet to show me it is not so bad…?

@Alan-Kilborn

I used it here.

@Alan-Kilborn

just be careful about notepad.destroyScintilla(self.hidden_scintilla)
Currently npp crashes when using this and then request another buffer.
There is already a merged fix but only available on next release.

This is the issue, I assume: https://github.com/notepad-plus-plus/notepad-plus-plus/issues/4487

[Ekopalypse]

@Alan-Kilborn

correct, that is the one.

So, like this: hidden = notepad.createScintilla()

That is actually a nice solution. The hidden instance’s entire text can be set to the matched text from the editor.research(). Then the hidden.rereplace() can be called and the result of the replacement read out into a Python string variable. Thanks, Eko; clearly I would not have thought of this technique without your pointer.

This is not a problem as I will do this near the top of the script, and never do a “destroy”:

try:
    hidden
except NameError:
    hidden = notepad.createScintilla()

and never do a “destroy”

There really is an “echo” in here, or just me repeating myself and not noticing.

:-D never ever - don’t even THINK about it unless your npp version is > 7.7.1 :-D

I guess, hidden.rereplace() is enough if you keep the text from editor and hidden in sync.
The replace function gets a match object which contains the position of the text to be replaced so from the replace function you could start the dialog, or?

@Ekopalypse

No, I’m not trying to “parallel” the text in the real editor and the hidden. If I set as the hidden editor’s entire text the match from the search, doing the replace on that guarantees the replace will succeed and the entire text left in the hidden editor’s buffer will be the replacement preview text. Long to explain but it seems to work.
