[ruby.parslet] Problem with transformation

[Eric Sagnes]

Hello,

I just started to play with Parslet, and I must say it is very intuitive.
Coding a parser was a breeze, but I am having some trouble with the transform 
part.

I made a simple if else conditional parser, and I can't get the transform to 
work.

Here the input:
'$if(foo)$ foo_block $elsif(bar)$ bar block $else$ baz $endif$'

And the parser result is:
{:text=>
  [{:conditional=>
     {:if_expression=>
       {:condition=>{:attribute=>{:attribute_atom=>"foo"@4}},
        :block=>" foo_block "@9},
      :elsif_expression=>
       [{:condition=>{:attribute=>{:attribute_atom=>"bar"@27}},
         :block=>" bar block "@32}],
      :else_expression=>{:block=>" baz "@49}}}]}

So far, so good.

I made a test rule to transform the :block value into some text
rule(:block => simple(:block) ){ "I am a block" }

And I got the following result
{:text=>
  [{:conditional=>
     {:if_expression=>{:condition=>nil, :block=>" foo_block "@9},
      :elsif_expression=>[{:condition=>nil, :block=>" bar block "@32}],
      :else_expression=>"I am a block"}}]}

Only the else_expression :block get transformed, what am I missing to have the 
:elsif_expression :block and :if_expression :block also transformed?

Thanks in advance,
