Signature help triggers after pressing , inside an object

[joshuali925]

To reproduce use the following init.lua

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
    vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", "--branch=stable", lazypath })
end
vim.opt.rtp:prepend(lazypath)

require("lazy").setup({
    {
        "williamboman/mason.nvim",
        build = ":MasonUpdate",
        dependencies = { "williamboman/mason-lspconfig.nvim", "neovim/nvim-lspconfig" },
        config = function()
            require("mason").setup()
            require("mason-lspconfig").setup({ ensure_installed = { "tsserver" } })
            require("lspconfig").tsserver.setup({})
        end,
    },
    {
        "hrsh7th/nvim-cmp",
        dependencies = { "hrsh7th/cmp-nvim-lsp", "hrsh7th/cmp-nvim-lsp-signature-help" },
        opts = { sources = { { name = "nvim_lsp" }, { name = "nvim_lsp_signature_help" } } },
    },
})

vim.cmd.colorscheme("habamax")

then create a js file vim repro.js, wait for tsserver, then type:

Object.freeze({
        foo: 'bar',

see completion menu opens, suggesting o: T.

The problem is that

1. I've configured the enter key to trigger completion, but in this case i want a new line. since the item is preselected, pressing enter will complete the item
2. the suggestion is based on parameter of Object.freeze(o), it's no longer valid when cursor is inside the curly brackets

If it's not easy to fix, is there a way to configure entry_filter to not display suggestion in this case? maybe like this

                        entry_filter = function()
                            local col = vim.api.nvim_win_get_cursor(0)[2]
                            return vim.api.nvim_get_current_line():sub(col, col) ~= ","
                        end,

But wanted to see if there's a better way. Thanks

@joshuali925 regarding the "enter selects the arg name instead of adding a new line" problem, I had the same issue.

Here is how I fixed it: antoinemadec/dotfiles@6b4b700
