check_select

NOTE: this is not an object method and is exported by default!

Direct calling should be for internal use only, but you may have been sent to this documentation by one of the modules which uses this function to process %option arguments.

%opts hash may contain (alias)

  Inclusive lists:
  "select layers"      (sl)
  "select colors"      (sc)
  "select types"       (st)
  "select linetypes"   (slt)

  Exclusive lists:
  "not layers"         (nl)
  "not colors"         (nc)
  "not types"          (nt)
  "not linetypes"      (nlt)

The values must be list references.

The space-separated terms in the keys above may now be underscore ("_") separated as well (this saves having to double-quote the item when using it as a hash key in the %options argument.)

If an option is omitted, all of that category are selected.

  ($s, $n) = check_select(\%selection_options);

$s will be a hash reference to inclusive items $n will be a hash reference to excluded items

Keys in the returned hash references are according to the above-listed alias conventions ($s->{l} contains a set of true values for selected layers (where the layer name is a string acting as the hash key.))

Note that the \%selection_options hash reference is a required argument (at this level.) Any functions which make it optional must declare a hash before passing to this.
