Headless install

[kradalby]

Hi

Great project, I have a couple of scenarios were using this package in a headless fashion would be neat, but the confirm (Yes/Cancel) seem to break that, any tips on how I can get that working?

Example command:

nvim --headless +"LspInstall go" +qa

Also, any plans on allowing multiple servers in one go? (LspInstall go elm css)

It's currently not possible to skip the confirm dialog but it sure would be nice. Now that I think about it, should we even have a confirm dialog at all? I can't remember right now why I decided to do this.

To install multiple servers at once, you can write a small lua function (see https://github.com/kabouzeid/nvim-lspinstall/issues/26#issuecomment-813345606). eg something like this:

--- install multiple language servers at once
function install_servers(servers)
  for _, server in pairs(servers) do
    require'lspinstall'.install_server(server)
  end
end

-- call it like this
install_servers({ "go", "elm", "css" })

Out of curiosity, what is your usecase for this? Sounds interesting.

Would also love to see this but it would probably need have an autocmd for when the server install is complete in a similar way to how Packer does it (PackerComplete https://github.com/wbthomason/packer.nvim#user-autocommands)

That way you write a update script (https://github.com/petertriho/dotfiles/blob/main/scripts/.local/bin/update) like this:

nvim +"autocmd User PackerComplete sleep 100m | qall" +PackerSync

@kabouzeid I have a similar usecase to @petertriho.

I have a CI/CD job that "builds" or packs my plugins and dotfiles so I can bring in everything to my company in one package.

Will have a look at the install script, but that also would be more useful without the confirmation :)

[kabouzeid]

I'll think about what the best way to approach this would be. I don't want to overcomplicate things. Ideas are welcome

@kabouzeid How about something like #84 ?

I am interested in being able to do this as well. My goal is to have a docker or podman container with my IDE that I can just pull to w/e machine I'm on (and for that matter, share with others). The manual steps and not being able to do LspInstall in headless is a hurdle for this.

So I'm interested in the progress for this. I can see that https://github.com/kabouzeid/nvim-lspinstall/pull/84 was closed due to a commit in main already fixing the confirmation dialog. But how is work going with the headless bit?
So far all I get is

% nvim --headless +"LspInstall go" +qa
Error detected while processing command line:
E492: Not an editor command: LspInstall g

% nvim --headless +"LspInstall go" +qa
Error detected while processing command line:
E492: Not an editor command: LspInstall g

@qwelyt I have the same goal as you and ran into the same issue. I figured out that I could add a sleep before and after the lsp install command:

nvim --headless +"sleep 5" +"LspInstall go" +"sleep 5" +qa

This is what I have in my Dockerfile:

RUN nvim --headless -c 'autocmd User PackerComplete quitall' -c 'silent PackerSync'
RUN nvim --headless +"sleep 5" +"silent TSInstall python bash" +"silent LspInstall python" +"silent LspInstall bash" +"sleep 60" +qa

and the output:

Step 5/8 : RUN nvim --headless -c 'autocmd User PackerComplete quitall' -c 'silent PackerSync'

You might need to bump the sleep duration, particularly the one after the LspInstall.

Far from ideal, but it works.
