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'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 (cfr. each).
