oneshot channel error

[emmanueltouzery]

This plugin was working fine for me, but recently I started getting this error:

Error executing callback:
.../packer/start/plenary.nvim/lua/plenary/async/control.lua:122: Oneshot channel can only send once
stack traceback:
[C]: in function 'assert'
.../packer/start/plenary.nvim/lua/plenary/async/control.lua:122: in function 'eof_tx'
...ite/pack/packer/start/telescope.nvim/lua/telescope/.lua:143: in function <...ite/pack/packer/start/telescope.nvim/lua/telescope/.lua:137>

I'm not sure what's the reason. Maybe it's even the repo or queries that i'm making that are slightly slower.

I may have tracked this to a telescope issue, I wrote some extra details there:
nvim-telescope/telescope.nvim#2517

There is some workaround, but I think it's not working 100% correctly due to shell quoting and escaping issues.

So the issue is that ast-grep recently changed to not output a trailing newline in json stream mode, which telescope does not handle well.

ast-grep now added the newline back, so their next release (after 0.37.0) should fix the issue.

I also opened a telescope PR to fix the issue on the telescope side, but they've not been responsive recently so I'm not really expecting it to be merged in a reasonable time.

So the next ast-grep release should fix the issue, I'll close this issue when that release is done. You can also close it earlier if you prefer.

try this. nvim-telescope/telescope.nvim#2846

[emmanueltouzery]

Before you wrote about your PR, I created mine as well:
nvim-telescope/telescope.nvim#3465

I checked your PR now, #2846. I think my alternative, #3465 is better, because as far as I can tell, your PR drops the last non-CR-terminated line from the input. Meaning in the case of ast-grep, with your PR, the last match is lost, i believe. With my PR it is not.

Note that I didn't look at the code at all, I just tested the PR.

However from the point-of-view of telescope-sg, I think it's all moot, because ast-grep 0.38.0 was now released which adds back the trailing newline and things work again out of the box.
