v0.4.0

BREAKING CHANGE: attributes to include are now under the :include option.

This means your decorators will need to change from @decorate trace("worker.do_work", [:arg1, :arg2]) to @decorate trace("worker.do_work", include: [:arg1, :arg2])

A new decorator, simple_trace has been added!

This will automatically add the input parameters, and result to the span attributes, and (optionally) generate a span name for you. Use it like this @decorate simple_trace() or like this @decorate simple_trace("worker.do_work"). The 0 arity version is great for normal module functions, while the 1 arity version allows you to specify a name for functions that would otherwise be ambiguous (handle_info, handle_event, etc.)
