Suppose my cli has two subcommands, sub1 and sub2. sub1 has an option -o that requires a value. This option has an autocomplete function assigned to it.

When I enter

$ cli sub1 -o <tab><tab>

autocomplete not only suggests my allowed values for -o, but also sub2. However, since an option value is required after -o, sub2 is an invalid suggestion at this point.

The same happens with required arguments.

Is there a possibility to suppress autocompletion of subcommands while still in the context of required arguments or options?
