NAME

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

SYNOPSIS

            # Create an array:
            #  demo:
            #    - red
            #    - green
            #    - yellow

            # Add a foo field to every item in the demo list, by default all
            # fixes will be in context of the iterated path. If the context
            # is a list, then '.' will be the path of the temporary context
            # variable
            do list(path:demo)
               if all_equal(.,green)
                   upcase(.)
               end
            end

            # This will result:
            #  demo:
            #    - red
            #    - GREEN
            #    - yellow

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

            # This will result:
            #  demo:
            #    - red
            #    - GREEN
            #    - yellow
            #  xyz:
            #    - red
            #    - GREEN
            #    - yellow

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 temporary field will be
       available in the root of the record containing the iterated data.
