This module centralizes the notions of hooks. Hooks are pointers that are to be set at runtime exactly once.

Sourcetype 'a t

The type of hooks containing 'a. Hooks can only be set.

Sourcetype 'a value

The content part of a hook.

Sourceval make : unit -> 'a value * 'a t

Create a new hook together with a way to retrieve its runtime value.

Sourceval get : 'a value -> 'a

Access the content of a hook. If it was not set yet, try to recover the default value if there is one.

Sourceval set : 'a t -> 'a -> unit

Register a hook. Assertion failure if already registered.
