I want to see differences between two files side-by-side (one on a left window, the other on a right window).
The purpose is not simply see the differences side-by-side, but also to make modifications on each window
and be able to show differences again.
Is such a thing possible to do in emacs?
Thank you
Tolu

M-x ediff :)
You can diff two files, a file with a buffer... Side by side, top
to bottom, whatever.
There is documentation for the ediff mode. Try C-h i ediff, perhaps it is
installed on your machine. If not (and if you want to suffer the whims
of your browser ;-) it's on the internets [1] too.

Have done `M-x ediff-files` and `M-x ediff-buffers`, but the two files
are put one on top of each other, rather than side-by-side. What setting
do I need to do to change to side-by-side?

Read the docs [1] ;-)
No, seriously: have you seen this little frame floating around,
showing: "type ? for help"?
If you go there (how ever your window manager/operating system
does that) and type ? you'll get a cheat sheet. Among them, there
is
"| -vert/horiz split"
So try typing "|", (the vertical bar, aka "pipe symbol") to toggle
between vertically and horizontally split display.
Enjoy
[1] I hope you don't take that too seriously. But there are more
things in there that I could tell you, promised!

Customize `ediff-split-window-function'. You can also just toggle with
the key | in any Ediff session.

Got confused on what to do because the window seemed to recognise the mouse
over options, but pressing mouse button did nothing. I repeatedly used
| which toggled between vertical and horizontal placement. Takes some
time to got used to this emacs thing. But I think I can do things that
I cannot do on other editors.

Yes, Emacs user interface is sometimes different :)
> Takes some time to got used to this emacs thing.
That's true, yes. I came from vi(m) and it took me
half a year of whining and swearing (but I knew what
I was going into). For me it was worth every bit of
it and them some.

That's true, too :-)

Note that by default Ediff uses a standalone control frame (which means
"window" in the outside world) and that frame should be selected to
enter the control commands. Dunno if that is related to your
experiences.
Anyway, it's possible to edit the currently Ediffed buffers. You can,
for example, copy regions from one side to the other. The quick help
(key: ?) is your friend. ? typed a second time removes the quick help.
It's also possible to edit the buffers manually while they are Ediffed.
You then hit ! to refresh the diff highlighting. h to toggle the
highlighting if it distracts while editing.
Michael.

That helps a lot Michael. Was initially bothered by the small command frame
that pops up and having to use ?. But using ? again to reduce the frame
is good and I like the highlighting.
I have some code that I need to split up into different files, and can get
to do some emacs practice doing so. I come from vscode and similar internal
environments (one big mess when tools are invented internally).

It would help with changes if I can also show tho parts that are common
between two files rather than the differences. Has anyone needed to do
this?

Note that you can also display the control window in the same frame as the two
buffers you're diffing, by setting `ediff-window-setup-function` to
`ediff-setup-windows-plain`. And you can toggle between the two with `M-x
ediff-toggle-multiframe`.

I am good with the different frames because of the small screen.

ediff and/or ediff-buffers is your friend.
