Seems to require an nvim newer than stable (current is 0.7.2).
Requires unmerged neovim changes.
Try again in a few months. Snippet:
require("lsp-inlayhints").setup() vim.api.nvim_create_autocmd("LspAttach", { callback = function(args) if not (args.data and args.data.client_id) then return end local bufnr = args.buf local client = vim.lsp.get_client_by_id(args.data.client_id) require("lsp-inlayhints").on_attach(client, bufnr) end, desc = "lsp-inlayhints", })
