get cookies name pattern look for a cookie named name and parse it using pattern.

set cookies name expr set cookie name to expr.

val add_handler : ( t -> Base.Unit.t ) -> Base.Unit.t

Register a callback that is called before a rewriting. The handler is expected to lookup some cookies and set some global variables.

This API is a temporary hack to allow to migrate from add_arg to the use of cookie, until ppxlib has been upgraded to pass cookies through.

Shorthand for: add_handler (fun t -> f (get t name pattern))

val add_post_handler : ( t -> Base.Unit.t ) -> Base.Unit.t

Register a callback that is called after a rewriting. The handler is expected to set some cookies from some global variables.
