Feature request: Compare two no-file buffer

[4goodapp]

I used this service to compare two text sometimes: https://text-compare.com
Is it posible to have option to open vdiff, ready to receive two text?
The current implementation require you to create two tmp buffer for that which isn't just quick.

[justbur]

You want a function for vdiff that creates two buffers to paste text into?

[4goodapp]

Yes, Exactly.
something like this ready to receive texts from lets say, clipboard

A wrapper like vim's linediff might make sense https://github.com/AndrewRadev/linediff.vim

Sorry for tailgating another feature request I would like to discuss - would it be simple to support diff-ing narrowed buffers? I could do a PR, as long as there isn't a conceptual issue with this approach.

[4goodapp]

Yes, something like that exactly 😀.

diff-ing narrowed buffers

Sorry I don't understand what you mean here.

[4goodapp]

However, The two texts (to compare) don't necessarily need to come from Emacs or an open file itself. It may just come from code I copied from let's Chrome web browser.

Would the buffers be deleted by default or kept by default? Would you want to name the buffers or give them a temporary name?

[4goodapp]

I think a temporary name would be OK, left right, text 1 - text 2, or just whatever you may think fit better. by default of course. Maybe add options to rename them.

Not sure what you mean here.

[justbur]

When you quit the diff, should the text be deleted or kept for future reference?

Yeah, why not. at least, by default yeah. Maybe not. I don't know... Chose the best, am fine with both 🙂.

try vdiff-temp-files on master

@justbur
Hello, Sorry for the delay,
Thank you very much for implementing this feature
I just test it and here is my thoughts:

When it comes to layout It works perfectly.
the auto scroll on both buffer is nice too, I didn't expect that one.

Now about the colors, Am little confused.
Like It's easy to see line that doesn't exist on the other side with the red dashes -----------
howerver on line with different text, only the color change.
An ideal solution would be to use different background to highlight the differences like in this example:

instead of just changing the color like in the current implementation:

[justbur]

The colors used are not set by this package. Their set by the theme you are using.

Hello,
vdiff-temp-files isn't available on Melpa yet.

[justbur]

It's been there since February. I just downloaded it again. Maybe you pinned it?

[4goodapp]

That's weird, I just try again but M-x vdiff-temp-files doesn't show nothing...
I remember it was working back in february.
