Ast_pattern.t ->
'b Base.Option.tget cookies name pattern look for a cookie named name and parse it using pattern.
val set :
t ->
Base.String.t ->
Migrate_parsetree.Ast_405.Parsetree.expression ->
Base.Unit.tset cookies name expr set cookie name to expr.
val add_handler : ( t -> Base.Unit.t ) -> Base.Unit.tRegister 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 :
Base.String.t ->
( Migrate_parsetree.Ast_405.Parsetree.expression, 'a -> 'a, 'b )
Ast_pattern.t ->
f:( 'b Base.Option.t -> Base.Unit.t ) ->
Base.Unit.tShorthand for: add_handler (fun t -> f (get t name pattern))
val add_post_handler : ( t -> Base.Unit.t ) -> Base.Unit.tRegister a callback that is called after a rewriting. The handler is expected to set some cookies from some global variables.
