Diff tool using Textual?

[paugier]

I encountered a situation in which I needed to do a merge in a server without Window system. I know that vim is good for that but I'm not good enough with this tool so I was missing a good diff tool implemented with Textual.

So this is just a silly idea but Meld is implemented in Python (https://gitlab.gnome.org/GNOME/meld) so I was wondering if it could be possible to create a good diff tool with Textual by reusing parts of Meld.
