Hello!

This is a report for bug with vimwiki using efm.

I am using nvim with efm-langserver with native lsp. I was setting up linting with markdownlint-cli installed using npm with efm but the linter was not working. I checked the output in ~/cache/nvim/lsp.log just to be clear what was going wrong.

.cache/nvim/lsp.log

It seems like it was not picking up my markdown files even though I had mentioned it in the config. It was showing vimwiki in the error of linting not supported instead of markdown which is a plugin. I uninstalled vimwiki and it worked.I checked the logs again and it picked it up properly this time and showed markdown instead of vimwiki.

System Settings:

    Arch linux
    0.5 nightly build
    npm version 7.16.0
    :VimwikiShowVersion
    Stable version: 2.5

Steps to Reproduce Error:

• Install vimwiki paq 'vimwiki/vimwiki' in neovim-nightly.
• Install markdownlint-cli with npm install -g markdownlint-cli.
• Setup efm with lsp and try to format the output with lsp format key binding (I have set it to format on autosave).
• Open a .md file and log the output when you press the format keybinding and you will see the error about vimwiki.
• Uninstall it and it will return back to normal as the second log.

        vim.api.nvim_command [[autocmd BufWritePost <buffer> lua vim.lsp.buf.formatting()]]
        vim.api.nvim_command [[augroup END]]
    end
