type t

val get : 
  t ->
  Base.String.t ->
  (Migrate_parsetree.Ast_404.Parsetree.expression, 'a -> 'a, 'b)
    Ppx_core.Ast_pattern.t ->
  'b Base.Option.t

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

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 environment variables.

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

val add_simple_handler : 
  Base.String.t ->
  (Migrate_parsetree.Ast_404.Parsetree.expression, 'a -> 'a, 'b)
    Ppx_core.Ast_pattern.t ->
  f:('b Base.Option.t -> Base.Unit.t) ->
  Base.Unit.t

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