Module `Proofview.NonLogical`

The NonLogical module allows the execution of effects (including I/O) in tactics (non-logical side-effects are not discarded at failures).

val read_line : string 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 raise : Exninfo.iexn -> 'a t: Pervasives.raise. Except that exceptions are wrapped with Logic_monad.Exception.

val catch : 'a t -> (Exninfo.iexn -> 'a t) -> 'a t: try ... with ... but restricted to Logic_monad.Exception.

val timeout : float -> 'a t -> 'a option t
val make : (unit -> 'a) -> 'a t: Construct a monadified side-effect. Exceptions raised by the argument are wrapped with Logic_monad.Exception.

val run : 'a t -> 'a: run performs effects.
