[ipxe-devel] Patch: Add ${mac/hexnone} settings type

[Levente LEVAI]

Hi

Just a thought: I think it is more useful to add some text manipulation to
the setting expansion code. I have implemented the following syntax:
${*<setting name>} expands to url_encode(<setting name>)
${-<list of chars to delete><last char repeated><setting name>} remove
   any character in <list of chars to delete> from setting when expanded

E.g. ${-::net0/mac} returns the thing you need.

My code is probably a bit longer than yours but not that much (I download
my ipxe through tftp so size is not a concern for me).
If interested I can submit a patch.

I also have thought about some bash-like syntax, but the above minimalistic
approach have served my purpose.

Best regards,
Levente Levai
