Module Logic_monad.NonLogical

The non-logical monad is a simple unit -> 'a (i/o) monad. The operations are simple wrappers around corresponding usual operations and require little documentation.

val return : 'a -> 'a t
val (>>=) : 'a t -> ('a -> 'b t) -> 'b t
val (>>) : unit t -> 'a t -> 'a t

Pervasives.(:=)

val (:=) : 'a ref -> 'a -> unit t

Pervasives.(!)

val (!) : 'a ref -> 'a t
val read_line : string t
val print_char : char -> unit t
val print_debug : Pp.t -> unit t

Loggers. The buffer is also flushed.

val print_warning : Pp.t -> unit t
val print_notice : Pp.t -> unit t
val print_info : Pp.t -> unit t
val raise : Exninfo.iexn -> 'a t

Pervasives.raise. Except that exceptions are wrapped with Exception.

val catch : 'a t -> (Exninfo.iexn -> 'a t) -> 'a t

try ... with ... but restricted to Exception.

val timeout : int -> 'a t -> 'a t
val make : (unit -> 'a) -> 'a t

Construct a monadified side-effect. Exceptions raised by the argument are wrapped with Exception.

val run : 'a t -> 'a

run performs effects.
