Suggestions for empty line.

[vishfrnds]

Common use case of copilot is
1 write a comment
2 go to next line
3 accept suggestion

This is not working, even when I force trigger cmp (cmp.mapping.complete()) then also it does not show any completion from copilot, but has other sources like buffer.
If I write a character copilot suggestion works, but not on empty line.

This is part of cmp. I believe cmp has a controllable number of characters required to trigger completion. Setting that to 0 may give you what you want, but there's nothing I can do on my end to force them to appear unless @hrsh7th knows something about this I am unaware of.

This is awesome plugin, but sorry for reopening this issue, as this in the main patern I use copilot as.
setting completion.keyword_length and sources[n].keyword_length as 0 makes other sources start suggesting for empty line, but not copilot.
I have also made copilot as sources[n].group_index=1 and rest as 2, still copilot needs atleast one character to trigger whereas other sources don't.

I did some testing. I set a hotkey to trigger copilot completions and tested it with no content on the line. The completion function triggers, but copilot returns no completions. Are you certain that copilot does this? If i type a comment character copilot completes comments fine. I guess I may be able to spoof a comment char on an empty line, but that seems weird.

[vishfrnds]

Yes, it does. For example: https://youtu.be/FL70Locz6oY?t=299
Basically you type comment of what you want something like "# get current price of stocks" and then go on next line and copilot brings up funtions for it.

I'll look into this. It may take a bit though.

@vishfrnds Quick update on this. The other day I actually managed to get copilot to get a completion on a newline, but cmp refused to show it, stating something along the lines of 'no prior character to complete' even when I try to manually trigger the menu. I think that this functionality is just incompatible with the way cmp is written. Unfortunately this is just an upstream problem I don't really have control over.

I am debating attempting to make a somewhat sizable PR to cmp which would fix this, but due to the scope of what is involved it would likely sit in the development branch for ages if it gets merged at all. I'll try digging into it at some point and see if there isn't an easier way, but I really wouldn't get your hopes up.

I am working on a few mechanical things that would make this type of feature work more smoothly which will be part of a rather sizable update coming soon:tm: but I think that for the time being getting this to integrate with cmp like the other results do is simply unrealistic. I'll continue to leave this open so that I can address it with the solution once said update is out, and I will probably put it in the docs as well.

As for the example implementations, I am happy to take input. Currently I was thinking that I would create a preview window triggerable by some command with selections and code previews.

Edit: Sorry if this notifies someone who saw it on a different thread, I was on mobile and posted this comment to the wrong one a bit ago...

@zbirenbaum
Would be glad to help, but sadly I don't really know lua and don't really know how to program a neovim extension.

I was just wondering: have you figured out what was preventing copilot from creating the suggestions? From my usage I see that the popup with completion appears and then if "refreshes" with copilot completions.

What's preventing this from happening on new line?

I'm a bit confused here. You should definitely not have any problems with completions appearing. If you are, you should check your node version.

For empty lines, that's more of a cmp issue than anything. Cmp requires a prefix to trigger a completion. I got it working at one point, but it was rough because pressing tab which I think most people use to navigate completions could no longer indent.

[jiriks74]

I have no problems with completions appearing, I was just wondering why it cannot be done with an empty line.

This fix will still be appreciated

It's hard for me to understand why the cmp.complete() returns true when it should return valid entries instead from the cmp-copilot/copilot.lua.

Hello, I have had some time to try and tackle this issue. I think something odd may happen when calling

-- line: 66, completion_functions.lua
 callback(format_completions({}, params.context, self.formatters))

Commenting this line gives the following example result (the completion is triggered immediately on the blank line):

@vishfrnds This is the desired functionality right?

@zbirenbaum I understand the point of the callback with the empty collections, but is there a way to go around this?

@zbirenbaum @vishfrnds deleting the line mentioned by @lpoto it worked for me
