Next Edit Suggestions / Smart Tab / Cursor Mode

[zackerydev]

Hey! Love this project and have been using it since it's inception!

I have been digging into the copilot language server implementation and noticed that it seems like they do provide functions for textDocument/handleNextEditRequest - which I think is the source of Copilot's (and Cursor's) Next Edit Suggestion feature.

Before I go digging any further, I wanted to get this discussion going on if this is something that is doable in this plugin. I would really really love to get the "Smart Tab" / Suggest Edit feature working in Neovim.

https://github.com/github/copilot-language-server-release I noticed that this repo doesn't seem to mention it - so maybe we need to wait for that? Anyway just looking for pointers / if anyone has explored this before, I've never written a Lua plugin - but can probably hack my way through it if it's feasible.

That looks awesome!
Since it is not in the official repo doc my guess is that it is not officially available outside of VSCode, so it might be a bit tricky to get working.
But I think it would be worth it if we can.
This is the first plugin I have worked on as well so if you need any pointers on how to set up it is quite fresh in my mind.
I recommend creating a branch and a draft PR if you would like some assistance so that I can chip in whenever, or just help move things along whenever.

If you turn on trace logs you should get a decent idea on the execution flow as it has helped me a lot while picking up how things work in this plugin.
I have also just added tests using mini.test, though I have not yet documented its usage. So if you find yourself wanting to run the tests let me know I will expedite the documentation on that.

Huge!

Thanks - I'm planning on giving it a go this weekend to see how far I can get, trying to use as much source I can find in VSCode and the LSP as prior art. Agreed that even if it's tricky, it will be very worth it. I've opened an issue upstream here to see about getting docs.

I have a feeling tpope will reply on your post on the official repo "NOT SUPPORTED" 😂😂
Though I hope I am wrong.

You made it further than I did then, I gave up trying to get it running through the debugger in VSCode and ended up just code reviewing way too much code.
Thanks for the PR link, I had seen some of that code but this makes it much easier to see the whole feature.
Last thing I stumbled upon is this, and I wondered if the nextEdit was just an extension of the getCompletion:

        fillClientCapabilities(t) {
            let n = (0, Z8.ensure)((0, Z8.ensure)(t, "textDocument"), "inlayHint");
            n.dynamicRegistration = !0, n.resolveSupport = {properties: ["tooltip", "textEdits", "label.tooltip", "label.location", "label.command"]}, (0, Z8.ensure)((0, Z8.ensure)(t, "workspace"), "inlayHint").refreshSupport = !0
        }

I have not dug further in that hole yet 😂

Take a look at this. Looks like some progress with reverse engineering vscode next edit suggestions. I asked for them to publish the GitHub repo so folks can see the code and help iterate. Would help if others show interest there as well!

In doing a review, is it just me or is the only "recent edits" being sent to the nes LLM essentially the changes since the last save? It appears it is just comparing the reading of the file contents to the current buffer content, isn't it? As opposed to showing actual recent history.

Here is what I'm referring to: https://github.com/Xuyuanp/nes.nvim/blob/aa0db74158264c749faefa384b5dafe7683ee9b3/lua/nes/init.lua#L75-L88

[zackerydev]

Yeah - as you mention on this issue I think this is the current place some kind of "edit history" API is being tracked

To anyone who wants to see this feature, please let yourselves heard over on the official LSP thread!

This could have the solution we've been looking for: https://www.reddit.com/r/neovim/s/wecSSoK2tJ

No worries and thanks for all the work you do for the NeoVim community :)

@tris203 i tried out your plugin and it looks like it is heading in a fabulous direction! Nice work!

One problem for me though is that I do not use Blink for completions. Is there any way I can still have regular copilot completions and also NES? It seems copilot.lua stops working once I enable copilot-lsp plugin.

@AntoineGS curious your thoughts on my comments here: copilotlsp-nvim/copilot-lsp#4 (comment)

Please jump in the conversation if you have anything to add or correct my comments on :)

FYI I have started integrating NES based on the work from the above repo :P Expect something over the next week!

Great news! As soon as you need a tester and/or feedback let me know!!
