Merging two anonymous structs

ruby-talk
1

Hello, I wonder if it's possible to merge two #struct objects ?

For example merging this one

#<struct #<Class:0xb7986c00> ident="237006/19748895", details="Some text here">

With this one

#<struct #<Class:0xb79893b0> libelle="Nice object", superficie=0, localisation="This town", prix="1000">

How can I do ??

Thanks

It's possible, but it's probably better to use Hashes instead. You can
always convert a Hash to a Struct [1] after you're done fiddling with
it. But if you really want to merge two structs, you could do something
like this:

def struct_join(main, other)
  mems = main.members + other.members
  vals = main.values + other.values
  Struct.new(nil, *mems).new(*vals)
end

I like your variable naming style here. I'd normally write 'members'
& 'values', but yours are concise & unambiguous. :slight_smile:
