This article is outdated, please check Setting up lsp + gopls + rust_analyzer in neovim since neovim has a built in lsp client now.

I spent more time than I’d like to admit trying to figure out how to convert a json object to a vim dict.

And then I gave up and went with using NeoVim’s built in py3eval to make my life easier.

~/.config/nvim/init.vim

let g:go_auto_type_info = 1
let g:go_auto_sameids = 1
let g:go_updatetime = 500
let g:go_fillstruct_mode = 'gopls'
let g:go_metalinter_command = 'gopls'
let g:go_term_reuse = 1
let g:go_term_enabled = 1
"let g:go_debug = ["lsp"]

python3 << EOF
