parsed() :: {state(), count(), bell(), IO.ANSI.Table.Style.t()} | :help
Link to this section Functions
Parses argv
(command line arguments).
argv
can be [“-h”] or [“—help”], which returns :help. Otherwise
it contains a US state/territory code (case-insensitive) and optionally
the number of observations to format (the first n ones). To format the
last n observations, specify switch --last
which will return a
negative count. To ring the bell, specify switch --bell
.
To apply a specific table style, use switch --table-style
.
Returns either a tuple of {state, count, bell, table_style}
or :help if --help
was specified.
