I often forget the comma between embedded table entries in lua code.

t = {
    a = { "str" },
    b = {
      {
        "str3",
        v = 1, 
      }  <<-- missing comma
      {
        ime_state,
        color = {fg = 'black', bg = '#f46868'}
      },
      ...
    },
    c = { "str1", "str2" },
},

Is there a way in vim / neovim to highlight such errors?

    There is, but it's complicated and error-prone. I suggest you use an LSP server for Lua. It'll tell you all the errors in the file, not just missing comma. Check this repository: nvim-lspconfig.

  • After installing the language server: scoop install lua-language-server and followed the instructions in help: server_configurations under sumneko_lua it works well.

I found the solution in help: lspconfig-server-configurations under sumneko_lua

Now I see every syntax error, while I type:
