[Shougo]

Really??

I have fixed the error...

[Shougo]

I have tested it but I don't reproduce it.
Please upload the screenshot by asciinema.

[Shougo]

Please test my minimal vimrc.

set rtp+=~/work/deoplete.nvim/
set rtp+=~/work/nvim-yarp
set rtp+=~/work/vim-hug-neovim-rpc
set rtp+=~/src/deoplete-lsp
set rtp+=~/src/nvim-lspconfig

let g:deoplete#enable_at_startup = 1

lua require'nvim_lsp'.rust_analyzer.setup{}
lua require'nvim_lsp'.cmake.setup{}
lua require'nvim_lsp'.clangd.setup{}

[Shougo]

I will close the issue if other people cannot reproduce the problem.

[ZhongYao Luo]

@Shougo
Sorry, I thought the other options were irrelevant, so I didn't post it. In fact, I tested it. The following configuration will reproduce the problem

set rtp+=~/.config/nvim/plugged/deoplete.nvim/
set rtp+=~/.config/nvim/plugged/deoplete-lsp
set rtp+=~/.config/nvim/plugged/nvim-lspconfig

let g:deoplete#enable_at_startup = 1

lua require'nvim_lsp'.rust_analyzer.setup{}
lua require'nvim_lsp'.cmake.setup{}
lua require'nvim_lsp'.clangd.setup{}
set ignorecase smartcase
set completeopt=longest,menu

set ignorecase smartcase me will appear Message in the matching list,
while the option set completeopt = longest, menu will cause the input me to become Me

[Shougo]

I cannot reproduce it...
Please check your deoplete is really the latest version.

[Shougo]

Sorry, I thought the other options were irrelevant, so I didn't post it. In fact, I tested it. The following configuration will reproduce the problem

Please don't make the lie in the minimal vimrc. It confuses me.

[ZhongYao Luo]

I cannot reproduce it...
Please check your deoplete is really the latest version.

[Shougo]

I cannot reproduce the problem. But I have added the hack feature for it.
Please use the latest of deoplete.

[Shougo]

reproduced... Please upload the screencast in the first.

[Shougo]

I have fixed the problem. Please update deoplete to the latest.

[ZhongYao Luo]

I have fixed the problem. Please update deoplete to the latest.

Fixed. I didn’t provide a screenshot because I couldn’t record it yet, thank you for the asciinema tool recommended

[Shougo]

OK.
