Body

The following error occurs when opening Neovim.

VimEnter Autocommands for "*"..function <SNR>91_MapTab の処理中にエラーが検出されました:
行   15:
E488: Trailing characters: SNR>133_IsAnEmptyQuote() ? '<C-O>:call <SNR>133_Indent(1)<CR>' : '<Tab>' }):  <SNR>133_IsAnEmptyQuote() ? '<C-O>:call <SNR>133_Indent(1)<CR>' : '<Tab>' })

copilot.vim: v1.31.0

Neovim version:

NVIM v0.9.5
Build type: Release
LuaJIT 2.1.1713773202

Edit: I upgraded Neovim to v0.10.0, but the problem still exists.

Edit: Sorry, this seems to be a bug of gabrielelana/vim-markdown.

Edit: Enabling vim-markdown and copilot.vim and opening a markdown file caused the problem. <Tab> mapping fallback functionary of MapTab() seems to make wrong expression. Sharing the same mapping between distinct plugins is too difficult...

Edit: The results of :autocmd are followed.

Are you still having this issue?

[yuntan]

Yes, I'm having the issue on copilot.vim v1.34.0.

Strangely, I'm using preservim/vim-markdown, and it seems to work fine. I'll try to help out though, could I get the results of :autocmd if possible?

[yuntan]

I've uploaded the results of :autocmd (too long...).
