Idea: This plugin should cache the last copilot buffer change for single-repeat.

[LiamKearn]

It would be cool if I could accept a copilot suggestion (word or line) and that suggestion would be "redoable" via the . key.

I'm not of a nvim lua api user but at a quick look:

vim.fn.setreg('.', 'etc')

doesn't seem to work. However:

print(vim.fn.inspect(vim.fn.getreg('.')))

does, maybe it's possible via some other API?

Not sure what you mean by "redoable". You want to insert the same text again? What's the use-case?

[LiamKearn]

Maybe I should have said "repeat" instead of redo | ..

I (like others) most usually use copilot for completion and I'd like to be able to repeat a buffer change it made elsewhere, usually I use it to complete signatures based on types and those changes can often be repeated.

Here is a quick screencast demoing what I mean: https://www.youtube.com/watch?v=t1fN4XNwIGk

You can write wrapper function for this.

local function accept_line()
  local start_cursor = vim.api.nvim_win_get_cursor(0)
  require("copilot.suggestion").accept_line()
  local end_cursor = vim.api.nvim_win_get_cursor(0)

  local text = table.concat(
    vim.api.nvim_buf_get_text(0, start_cursor[1] - 1, start_cursor[2], end_cursor[1] - 1, end_cursor[2], {}),
    "\n"
  )

  vim.fn.setreg("*", text)
end

vim.keymap.set("i", "<M-Down>", accept_line, {})

This will copy the inserted text into clipboard. Then you can paste it wherever you want.

But this is outside the scope of this plugin.

Firstly, thank you for effort of piecing together a quick code example :)

I wouldn't say I disagree but every other way (that I can recall) of interacting with my buffers respects the redo register. To me integrating with an established core feature is the sort of thing I'd call polish on a plugin (as opposed to bloat).

By any chance do you use the copilot-cmp integration for this plugin? Could you advise me if that works with the redo register via nvim-cmp?

Copilot acts as a language server that gives text suggestion. I don't think any of the language server clients support dot repeat for inserted text.

Sorry, nope.

Could you advise me if that works with the redo register via nvim-cmp?

If nvim-cmp supports it, sure. copilot-cmp integration just gets the suggestion from copilot, then feeds it to cmp for handling it.
