NAME

       Catmandu::Fix::Bind::list - a binder that computes Fix-es for every element in a list

SYNOPSIS

            # Create an array:
            #  demo:
            #    - test: 1
            #    - test: 2
            add_field(demo.$append.test,1)
            add_field(demo.$append.test,2)

            # Add a foo field to every item in the demo list, by default all
            # fixes will be in context of the iterated path
            do list(path:demo)
               add_field(foo,bar)
            end

            # Loop over the list but store the values in a temporary 'loop' variable
            # Use this loop variable to copy the list to the root 'xyz' path
            do list(path:demo,var:loop)
               copy_field(loop.test,xyz.$append)
            end

            # This will result:
            #  demo:
            #    - test: 1
            #    - test: 2
            #  xyz:
            #    - 1
            #    - 2

DESCRIPTION

       The list binder will iterate over all the elements in a list and fixes the values in
       context of that list.

CONFIGURATION

   path
       The path to a list in the data.

   var
       The loop variable to be iterated over. When used, a magic field will be available in the
       root of the record containing iterated data.
