There was a problem hiding this comment.
The trick here is that due to the type constraint these values will never reach -1, even if called with --password=-1 as it's turned into "-1". We can't use nil because it just says the default is not defined (or really it's empty, since it cannot check for "not defined"), so this looked like a nice alternative. We could also take the golang approach and pass a {}, but since it's a full hash in ruby unlike Golang's empty interface I just picked the next best thing...
Due to limitations in Thor it is not possible to set an argument to be both optional and its value to be mandatory. E.g. the user supplying the --password argument is optional and not always required, but whenever it is used, it requires a value. Handle options that were defined with mandatory values in a way that fails with an `ArgumentError` if the value is missing, i.e.: ``` > inspec exec examples/profile --password ArgumentError: Please provide a value for --password. For example: --password=hello. ``` It works without `--password` or with `--password=arg`. Also handled for `--sudo-password`. Fixes: #1901 As suggested: #1904 Signed-off-by: Dominik Richter <[email protected]>
