Can I run :LspInstallServer with no interaction?

[Itto1992]

Thank you for creating this nice repo!
I use this repo every my vim-environment.

I am creating a docker environment for neovim.
And I want to install some servers in the Dockerfile like below.

RUN nvim tmp.py -c 'LspInstallServer' -c 'qa!'

However, :LspInstallServer requires a confirmation before installation, which blocks the installation.
This phenomenon cannot be solved by declaring ENV DEBIAN_FRONTEND noninteractive.

If there is any solution to run installation command without interaction, could you tell me how to do it?
Thank you in advance.

not perfect, but here's what I ended up with for typescript @Itto1992 :

vim -c ':LspUninstallServer typescript-language-server' -c ':qa'
vim /tmp/file.ts -S <(echo -e "LspInstallServer! \n while index(lsp_settings#installed_servers(), {'version': '', 'name': 'typescript-language-server'}) == -1 \n sleep 1 \n endwhile \n :qa")

I wanted to do the same kind of scripted install. Still no simple recommended solution?

In my case I'm trying to install 3 (bash, markdown, yaml), and the interactive prompting isn't so bad but trying to get it to block until ALL the installs are finished seems like it's going to be a pain. @rmartine-ias it looks like that waiting for completion is the part your workaround is for?

@dbarnett yep, it wakes up every second to check if it's done.
This would do it for you probably (works on my machine):

#!/usr/bin/env bash

vim -c ':LspUninstallServer bash-language-server' -c ':qa'
vim /tmp/file.sh -S <(echo -e "LspInstallServer! \n while index(lsp_settings#installed_servers(), {'version': '', 'name': 'bash-language-server'}) == -1 \n sleep 1 \n endwhile \n :qa")

vim -c ':LspUninstallServer marksman' -c ':qa'
vim /tmp/file.md -S <(echo -e "LspInstallServer! \n while index(lsp_settings#installed_servers(), {'version': '', 'name': 'marksman'}) == -1 \n sleep 1 \n endwhile \n :qa")

vim -c ':LspUninstallServer yaml-language-server' -c ':qa'
vim /tmp/file.yaml -S <(echo -e "LspInstallServer! \n while index(lsp_settings#installed_servers(), {'version': '', 'name': 'yaml-language-server'}) == -1 \n sleep 1 \n endwhile \n :qa")

FYI I used a variation on this using timer_start() instead of :sleep, because it was bugging me having the UI frozen during the install.

I defined a function in my vimrc:

" Helper for installing servers programmatically
func LspInstallServerThenQuit(name) abort
  let s:lsp_server_installing = a:name
  execute 'LspInstallServer!' a:name
  call timer_start(500, funcref('s:QuitIfLspServerInstalled'), { 'repeat': 100 })
endfunc

func s:QuitIfLspServerInstalled(...) abort
  for l:s in lsp_settings#installed_servers()
    if l:s.name ==# s:lsp_server_installing | qa | endif
  endfor
endfunc

then called it from cli:

$ vim +'set ft=sh' +'augroup lsp_auto_enable | autocmd!' +'call LspInstallServerThenQuit("bash-language-server")'

Without the lsp_auto_enable thing I kept getting some weird error like

Error detected while processing VimEnter Autocommands for "*"..function lsp#enable[22]..<SNR>167_register_events[20]..<SNR>167_on_text_document_did_open[12]..<SNR>167_ensure_flush[1]..lsp#utils#step#start[1]..<SNR>197_next[9]..<lambda>29[1]..<SNR>167_ensure_start[54]..lsp#client#start[28]..<SNR>198_lsp_start[12]..lsp#utils#job#start[1]..<SNR>199_job_start:

that kept blocking the commands from finishing.
