hooks

Hooks are pieces of code that are run before or after the flor executor consumes a message.

Hooks are external to flor definitions or executions, they are triggered for any matching message, whatever the execution. Traps are set by executions and generally terminate when their execution terminates.

setting a hook programmatically

flor = Flor::Unit.new('envs/test/etc/conf.json')
# ...
flor.hooker.add('journal', Flor::Journal)

The journal is a minimal example of hook. It's used in spec to track messages emitted by test executions.
