To get autocompletion for the config, it is best to put the config in a json file next to the actual lsp configuration. To do that, just put a grustonnet-ls.lua file in your after/lsp directory with the following content. The config will be loaded from a grustonnet.json file.

local function getJson(filename)
	-- https://neovim.io/doc/user/lua.html#lua-script-location
	local current_file = debug.getinfo(1, "S").source:sub(2)
	local current_dir = vim.fn.fnamemodify(current_file, ":h")

	local file_content = vim.fn.readfile(current_dir .. "/" .. filename)
	return vim.json.decode(table.concat(file_content, "\n"))
end

local grustonnet_settings = getJson("grustonnet.json");
return {
	cmd = { "grustonnet-ls" },
	filetypes = { 'jsonnet', 'libsonnet' },
	root_markers = { 'jsonnetfile.json', '.git' },
	settings = grustonnet_settings,
}

To get a live preview and debugger support you can install my jsonnet-tools plugin

IntelliJ

Just don’t. IntelliJ is probably nice for Java development, but for other languages it just seems rather bad and does not have native support LSP, DAP, or Treesitter.

To get basic support you can use lsp4ij. However, you either need to separately install syntax highlighting or use the slow Treesitter bridge of the language server.
