Creating a design rule only for inner/outer layers is not possible

[chfriedrich]

When I create a custom Rule in KiCad, I can use the syntax

(rule "HV to HV (IL)"
	(layer inner)
	(constraint clearance (min 2.4mm))
	(condition "..."))

to limit its scope to all inner layers.

This is not possible with kiutils, because the layers member is a string, which gets parsed to

(rule "HV to HV (IL)"
	(layer "inner")
	(constraint clearance (min 2.4mm))
	(condition "..."))

with the word inner in appostrophs, which is not understood by kicad.

I fixed this temporarily now by changing the if condition in line 187 of dru.py to

        if self.layer is not None:
            if self.layer == 'inner' or self.layer == 'outer':
                expression += f'{indents}  (layer {dequote(self.layer)})\n'
            else:
                expression += f'{indents}  (layer "{dequote(self.layer)}")\n'
