Riak pre-commit hook in Erlang?

Question

How would I write a pre-commit hook to change all of the letters in the value of my key/value pairs to be ALL UPPERCASE in a particular bucket?

Answer 1

Using this example of pre-commit hook: https://github.com/basho/riak_function_contrib/blob/master/hooks/pre-commit/js/validate_json.js, you should be very close to a solution, using the standard value.toUpperCase();.
