EDAM file: toplevel list of string

[qarlosalberto]

I see in the EDAM documentation:

Is it possible to use it in all the tools? For example for GHDL? I'm having errors with this EDAM file:

{
  "files": [
    {
      "name": "/home/carlos/repo/colibri2/tests/project_manager/tools/edalize/helpers/ghdl/half_adder_tb.vhd",

      "is_include_file": false,
      "include_path": "",
      "logical_name": ""
    },
    {
      "name": "/home/carlos/repo/colibri2/tests/project_manager/tools/edalize/helpers/ghdl/half_adder.vhd",
      "file_type": "vhdlSource-2008",
      "is_include_file": false,
      "include_path": "",
      "logical_name": ""
    }
  ],

      "analyze_options": [],
      "run_options": []
    }
  },
  "toplevel": ["half_adder_process_tb", "other_tb"]
}

Error: 'list' object has no attribute 'split'
