Installing extensions from a script

[elentok]

Hi,

I'm using a script in my dotfiles to install neovim and all of the plugins I need.

How can I install a Coc extension in a script?

I tried several options:

nvim "+CocInstall $extensions"
nvim --headless "+CocInstall $extensions"
nvim --headless "+CocInstall $extensions" +qall

The first one works but doesn't close nvim afterwards (so the install script can't run unattended),
the second one remains blank and the third exits immediately.

For reference to install vim-plug plugins I run:

nvim --headless +PlugInstall +UpdateRemotePlugins +qall

If I just go to ~/.config/coc/extensions and run yarn add $extensions will that be enough? or does coc register the extensions somewhere else?

Thanks for all the great work you're doing, I love this plugin! 👍

Yes, that's all you need to do, except that the location is different on windows.

does coc register the extensions somewhere else.

Is's possible for a vim plugin to regist custom extension root, then you need to use a plugin manager to install that plugin, but none of current extensions is vim plugin right now.

Cool, thanks!

I wanted to run this in a docker build file, and I found a hack that worked: RUN timeout 1m nvim --headless +CocInstall; exit 0

I found a good solution: nvim --headless +"CocInstall -sync $extensions|qa"

None of the solutions above works in my case. I've defined coc_global_extensions and inside vim :CocInstall works just fine. The problem is that I'm trying to run an unattended script where yarn is not available (but npm is)

Is there anything I'm missing to try?

I wish I could do

nvim --headless +CocInstall +qall

But exits right away

In the meantime this is doing the job for me:

mkdir -p ~/.config/coc/extensions && cd ~/.config/coc/extensions
if [ ! -f package.json ]; then
  echo '{"dependencies":{}}' >package.json
fi
COC_EXTENSIONS=$(nvim --headless -c 'echo coc_global_extensions' +qa 2>&1 | awk -v RS="'" '!(NR%2)')
npm install $(echo $COC_EXTENSIONS) --global-style --ignore-scripts --no-bin-links --no-package-lock --only=prod

if len(g:coc_global_extensions) > 18, it will

❯ vi --headless -c "call coc#util#install_extension(['-sync'] + g:coc_global_extensions) |qa"
Error on request (installExtensions): Vim(return):E699: Too many arguments%

❯ vi --headless -c'echo g:coc_global_extensions | quit'

So tail -n1 is needed.

And I prefer sed than awk:

git clone --depth=1 https://github.com/Shougo/dein.vim \
	~/.local/share/nvim/repos/github.com/Shougo/dein.vim &&
	vi -c'call dein#update() | quit' &&
	mkdir -p ~/.config/coc/extensions &&
	echo '{"dependencies": {}}' >~/.config/coc/extensions/package.json &&
	npm install -C ~/.config/coc/extensions \
		$(vi --headless -c'echo g:coc_global_extensions | quit' 2>&1 | tail -n1 |
			sed "s=\(', '\|\['\|']\)=\n=g") &&
	mkdir -p ~/.config/coc/extensions/coc-gist-data &&
	echo '{"token": "gho_"}' >~/.config/coc/extensions/coc-gist-data/secret.json  # disable prompt

works for me.
