Ruby array to hash

krisjaniszakis

Hi is there a fast way or some ruby libraries how to convert array[] to hash{} ?
Example of array[]:
a=[] a << [test1, test2, test3, test4]

How can I fill in hash{} with entity name and value?

#hash_to_array... including nested hashes

    def h2a(h={})
        a=[]
        a=[*h] if h.is_a?(Hash)
        a.dup.each_with_index{|e, i|
            a[i][1]=h2a(e[1]) if e[1].is_a?(Hash)
        }
        return a
    end

#array_to_hash... including nested arrays

    def a2h(a=[])
        h={}
        a.each{|e| h[e[0]]=e[1] } if a.is_a?(Array)
        h.dup.each_with_index{|e, i|
            h[e[0]]=a2h(e[1]) if e[1].is_a?(Array)
        }
        return h
    end

What do you mean by the name and value of an entity?

Assum,ing every component instance has a unique name assigned...

  model = Sketchup.active_model

  comps = model.entities.grep(Sketchup;;ComponentInstance)
  pairs = comps.map {|i| [i.name,i] }
  hash  = Hash[ *pairs.flatten! ]

Thanks TIG your generous script prints out unique arrays and it is not realy the exact case.

thomthom -> name, value
h{"name" => value, "name" => value,}

Looks like I havn't told all the details.

I have multidimensional array[] in Ruby
I want to send array[] to Webdialog using dialog.execute_script()
I want to send to PHP and arrange and do stuf with array[]

My array[] looks like this array[[value1, value2, value3,...],[value1, value2,...],...]

Im trying to transform array[] to hash{}
hash{0=>[0_0=>value1,0_1=>value2,0_2=>value3,...],1=>[1_0=>value1,1_1=>value2,...],...}

maybe I don't need transform, maybe I can send directly from Ruby to PHP without sending to Webdialog ?

My code makes an array into a hash and all its nested arrays into hashes too.
And vice versa for hashes to arrays.

It's specifically written to de-hash/re-hash hash data for use in attributes - which can contain arrays but not hashes...

In you case you just need to make simpler versions that doesn't iterate through the array's/hash's contents...

Also reading your OP and comments you could easily write all of this info directly into a hash initially and not worry about later manipulations

Thanks TIG it is a good point
