Question

Hello!
When I use mini.diff and I toggle the overlay, I would like to be able to go into the hunks to be able to copy from them, how can I do this?
I would like to be able to select and copy virtual text, I guess.

I use lazyvim with my config on top.

Thank you!!

Hi!

I am afraid, this is not possible and out of scope for 'mini.diff'. Its overlay text is implemented via virtual text which is not meant for "go inside of it".

I would like to be able to select and copy virtual text, I guess.

That is partially possible via this mapping. "Partially" - because the whole reference text of the hunk will be yanked (copied).

Hello, thank you for your answer!! Added to my config.

Is it possible to me create a temporary buffer with the current content including virtual lines and in that buffer?

You probably could write a function for that, yes. There should be enough information in MiniDiff.get_buf_data() to achieve that: hunks with hunk data and ref_text with reference text. Use vim.api.nvim_buf_get_lines(0, 0, -1, false) to get lines of the current buffer.

A less robust way would be to get information using extmarks from the namespace named MiniDiffOverlay. Use vim.api.nvim_get_namespaces().MiniDiffOverlay to get its id. It is less robust because there will be no guarantee that this won't be refactored in the future to use something else. It probably won't, but still I have to warn here.
