type 'a t

type of flags to a command with accumulator type 'a

val name : 'a t -> string

type ('a, 'b) create = string ->
       ?aliases:string list ->
       ?full_flag_required:bool -> 'b -> doc:string -> 'a t

Template for flag-creation functions

val of_arg : Core.Std.Arg.t -> unit t

Flag handling without an accumulator

rest f: a flag that signals the end of flag processing. all remaining arguments are passed to the f

Deprecated This is the old deprecated interface to Flag

val create : ?aliases:string list ->
       ?full_flag_required:bool ->
       name:string ->
       doc:string ->
       'a Action.t -> 'a t

val lift : 'a t ->
       project:('b -> 'a * ('a -> 'b)) -> 'b t

lift t ~project transforms a flag with accumulator type 'a into a flag with a more informative accumulator type 'b provided that project x returns a pair consisting of 1. a 'a-value extracted from the 'b-value x, and 2. a function for rebuilding a modified 'b-value from the modified 'a-value resulting from processing the flag.

The intended use pattern for lift is when 'b is a record type with a field foo of type 'a and project is fun r -> (r.foo, (fun foo' -> { r with foo = foo' }))

val lift_unit : unit t -> 'any t

val to_spec : ('accum -> 'accum) Pervasives.ref ->
       'accum t -> ('c, 'c) Core.Std.Command.Spec.t

val to_spec_unit : unit t -> ('c, 'c) Core.Std.Command.Spec.t
