NrrwRgn agnostic to changes by vim-over

[Konfekt]

After a change in the scratch buffer by :%s using https://github.com/osyo-manga/vim-over , the changes are not reflected upon writing the scratch buffer by :write!.

I do not understand. What is vim-over doing? And where are you doing
this?

Best,

https://github.com/osyo-manga/vim-over is a tool that shows the strings as they will appear after :substitute next to them while typing the regular expressions.

To reproduce, after installing https://github.com/osyo-manga/vim-over map S to

nnoremap <silent> S ms:OverCommandLine<CR>:%substitute:\v::cgI<Left><Left><Left><Left><Left>

and narrow a region, say the buffer containing

hello

by NrrwRgn. In the scratchbuffer, hit S and replace hello by bye. Then the changes of the scratchbuffer are not reflected in the original buffer, even on :write! in the scratchbuffer.

Granted that this could be an issue of https://github.com/osyo-manga/vim-over but perhaps you have a good idea why so at least?!

Thanks I'll check it out. Can you post the output of
:au BufWriteCmd

That should contain something like this:
...
NrrwRgn1 BufWriteCmd
<buffer=5>
:call s:WriteNrrwRgn(1)

And afterwards please also show the output of
:au NrrwRgn1

Ok, in a nrrwrgn buffer au BufWriteCmd gives

and au NrrwRgn1 gives

NrrwRgn1  CursorMoved
    <buffer=3>
              :call s:UpdateOrigWin()

Besides, a problem sometimes occuring with vim-over without being able to make it reproducable, is that the changes are not recognized by Vim, so that :update does not save them, only :write.

Okay, I see the problem. The scratch window is not marked modified and therefore the content is not written back. That might be considered a bug in the vim-over plugin.
I have removed that check now, since it seems to be useless.

[Konfekt]

Thanks! Can you explain How to Mark the Window modified to remove the apparent bug in vim-over

In the scratch window, issue :set modified

But this shouldn't be necessary anymore. I removed that check.

Best,

Christian
