ArgParse error “too many arguments”

General Usage

Hi,

I am trying to use ArgParse to read options from command line. It works when I have three options, but when I add another option it throws “too many argument” error. I appreciate your help.

using ArgParse
function parse_commandline()
    s = ArgParseSettings()
    @add_arg_table s begin
        "--opt1"
        "--opt2"
        "--opt3"
        "--opt4"
    end
    return parse_args(s)
end
parsed_args = parse_commandline()

ERROR: LoadError: ArgParseError("too many arguments")

Let’s keep the discussion centralized at ArgParse error "too many arguments". Double-posting can lead to duplication of effort.
