NAME

Catmandu::Fix::Bind::each - a binder that executes fixes for every (key, value) pair in a hash

SYNOPSIS

    # Create a hash:
    # demo:
    #   nl: 'Tuin der lusten'
    #   en: 'The Garden of Earthly Delights'

    # Create a list of all the titles, without the language tags.
    do each(path: demo, var: t)
        copy_field(t.value, titles.$append)
    end

    # This will result in:
    # demo:
    #   nl: 'Tuin der lusten'
    #   en: 'The Garden of Earthly Delights'
    # titles:
    #   - 'Tuin der lusten'
    #   - 'The Garden of Earthly Delights'

    # Upcase every key in the root hash
    # foo: bar
    # test: 1234
    do each(path:., var: t)
       upcase(t.key)
    end

    # This will result in
    # FOO: bar
    # TEST: 1234

DESCRIPTION

The each binder will iterate over a hash and return a (key, value) pair (see the Perl each function for the inspiration for this bind) and execute all fixes for each pair.

The bind always returns a var.key and var.value pair which can be used in the fixes.

CONFIGURATION

path

The path to a hash in the data.

var

The temporary field that will be created in the root of the record containing a key and value field containing the key and value of the iterated data.
