Buildozer new command: copy rule

[srawlins]

I'd like a buildozer command that copies a rule. Right now buildozer has copy <attr> <from_rule> to copy attribute values, and new <rule_kind> <rule_name> to make a new rule, but I would like:

• a new command copy_rule <from_rule> <rule_name>
• or perhaps a new arg on new: new <rule_kind> <rule_name> [based_on <from_rule>]

This can only be achieved today using scary usage of things like print rule or print startline and print endline combined with sed or something... :fearful: some other tricky scripting.

buildozer 'copy_rule //a:b' //b:c //d:e ...

SGTM -- are you able to send a PR?

@pmbethe09 I came across this issue a few days back and ended up using print rule for my use case. I think copy_rule would be useful, and I can put up a PR for buildozer 'copy_rule //a:b' //b:c //d:e ...; however, I wanted to check in first that this is still desirable since it's been a few years.

Is this something that might see the light of day? Or is it too stale to be resurrected?
