          Custom filetypes.
          Your new file format will be merged in with those that already exist.
          If you pass in one that already exists, your configuration will override the built-in
          configuration.

          Example:
          ```nix
            filetypes = {
              python = {
                left = "print(f'";

                midVar = "{";
                rightVar = "}')";

            };
          ```

      ignoreTreesitter = helpers.defaultNullOpts.mkBool false ''
        Never use treesitter to find a variable under the cursor, always prompt for it - overrides
        the same setting on `debugprint()` if set to true.
      '';
