Module `Ppxlib__Driver.Cookies`

type t

val get : t -> Ppxlib__.Import.string -> (Ppxlib__.Import.expression, 'a -> 'a, 'b) Ppxlib.Ast_pattern.t -> 'b Ppxlib__.Import.option: get cookies name pattern look for a cookie named name and parse it using pattern.

val set : t -> Ppxlib__.Import.string -> Ppxlib__.Import.expression -> Ppxlib__.Import.unit: set cookies name expr set cookie name to expr.

val add_handler : (t -> Ppxlib__.Import.unit) -> Ppxlib__.Import.unit

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.

val add_simple_handler : Ppxlib__.Import.string -> (Ppxlib__.Import.expression, 'a -> 'a, 'b) Ppxlib.Ast_pattern.t -> f:('b Ppxlib__.Import.option -> Ppxlib__.Import.unit) -> Ppxlib__.Import.unit: Shorthand for: add_handler (fun t -> f (get t name pattern))

val add_post_handler : (t -> Ppxlib__.Import.unit) -> Ppxlib__.Import.unit: Register a callback that is called after a rewriting. The handler is expected to set some cookies from some global variables.
