hs.preferences - Property List Editor with NSKeyedArchiver support

[latenitefilms]

Thank you so much @cmsj for giving us hs.plist - HUGELY appreciated!

Apologies for the delay in testing it - I've only just had a chance to have a proper play.

hs.plist.read and hs.plist.write are awesome - and seem to work as advertised.

However, I'd love something like hs.plist.edit(filepath, key, value), so that we can easily edit existing plist files (similar to how the defaults command line tool works). I'd imagine most Hammerspoon users that make use of hs.plist will be using it to modify macOS Preferences - so I feel like an edit feature would be really handy. As you say yourself in the documentation, it's a little bit risky reading, modifying then re-writing a plist via Lua.

Also, as discussed here, given that a lot of macOS Preferences files now use NSKeyedArchiver, having support to be able to unarchiver then re-archive preferences would also be amazing. I have no idea how complicated this is to do however.

Thoughts?

Thanks again for all your amazing work!!

FYI - It looks like @asmagill has already played around with NSKeyedArchiver in readArchiverDataForUTI?

@asmagill - I'm considering having a play with your hs._asm.preferences extension, and see if I can work out how to add NSKeyedArchiver support myself. I know you're very busy, but any tips or hints before I begin?

I wonder if this (i.e. NSKeyedArchiver support) is something you'd be interested in tackling @waynezhang ?
