Module `Coded.Create`

Use Create(B) to make an annotation system module for the symbols defined in B and decoded with

f_decode

.

Parameters

module B : Basis

Signature

type iota = private

| Iota of {
1. symbol : B.Symbol.t;
2. position : Cf_decode.position;
}

The type of an input event, comprising a symbol and its position.

type span = private

| Span of {
1. start : Cf_decode.position;
2. limit : Cf_decode.position;
}

Representation of a span of positions, comprising the pair of a) the position of the first symbol in the span, and b) the position of the symbol immediately following the last symbol in the span. Accordingly, if both the start and limit fields have the same serial number, then the span is empty, comprising no symbols.

type +'a form = private

| Form of {
1. value : 'a;
2. span : span option;
}

A value annotated with its span of text in the input stream.

module Scan_basis : 
  Cf_scan.Basis
    with type Symbol.t = B.Symbol.t
     and type iota = iota
     and type position = Cf_decode.position
     and type 'a Form.t = 'a form

A basis module for constructing a

Inclusion of the

f_scan

production form signature.

include Cf_scan.Form with type 'a t := 'a form

val imp : 'a -> 'a form

Scanners use imp value to create a value form with a distinguished implicit position, i.e. not located in the input stream.

val dn : 'a form -> 'a

Scanners use dn form to get the value wrapped in form.

val mv : 'a -> 'b form -> 'a form

Scanners use mv value form to make a form containing value attributed with the same position as form.

val span : 'a form -> 'b form -> 'c -> 'c form

Scanners use span a b value to make a form containing value attributed to the span of positions from a to b.

val map : ('a -> 'b) -> 'a form -> 'b form

Use map f v to apply f to the value enclosed in v to make the result annotated with the same position as v.

val join : ('a -> 'b -> 'c) -> 'a form -> 'b form -> 'c form

Use join f a b to apply f to the values enclosed in a and b to make the result annotated with the span that covers the overlap of the positions of both a and b.

val collect : 'a form list -> 'a list form

Use collect s to collect all the values enclosed in the forms s to a single list annotated with the span that overlaps all the positions in s.

val force : 'a Lazy.t form -> 'a form

Use force z to force the lazy value enclosed in z.

val to_iotas : ?start:Cf_decode.position -> B.Symbol.t Seq.t -> iota Seq.t

Use to_iotas s to lift s into a sequence of iota values. Use ~start to provide an explicit starting position.
