Autocomplete breaks second order ins-completion #18044
Description
Activity
That pr doesn't make a difference for this as far as I can tell.
As a temporary workaround, creating mappings like this works:
inoremap <C-X><C-R> <Cmd>set noac<CR><C-X><C-R><Cmd>set ac<CR> inoremap <C-X><C-L> <Cmd>set noac<CR><C-X><C-L><Cmd>set ac<CR>Though I don't know if that helps you pinpoint the issue.
I am not sure what the correct behavior ought to be. With
:set acwhen I type^X^Lon an empty line, I see a list of lines. If I type it again, the menu gets dismissed as it should be. Without autocomplete, it opens a newline when the keys are typed again (not correct). What is your use case for^X^L?The second
<C-X><C-L>should insert the next line after the one you just completed, see this part of the docs:CTRL-X CTRL-L After expanding a line you can additionally get the line next to it by typing CTRL-X CTRL-L again, unless a double CTRL-X is used. Only works for loaded buffers.Here's an example:

compl-currentis also affected, and probablycompl-keywordandcompl-define.Follow-up

on Aug 23, 2025 Sorry I'm a bit late, but does patch 9.1.1670 actually fix this for you @girishji?
The example in the asciicast above still doesn't work for me with:
