Set CoC nodejs path dynamically

Question

Currently for CoC I am setting the nodejs path like this:

let g:coc_node_path = '/usr/local/.nvm/versions/node/v12.4.0/bin/node'

But I want this variable to be set to the output of which node. How can I do this? The CoC config guide does not mention this, and it's my understanding that this is a vim script specific feature.

Answer 1

Perhaps I should have searched the internet more before I asked this question. I was able to accomplish what I needed using the system function.

So here I needed to do:

let g:coc_node_path = substitute(system('which node'), '\n', '', '')

The substitute is necessary because we need to get rid of the new line at the end of the output, otherwise the path is invalid.
