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
