Module With_text

A With_text.t is a value paired with the full textual representation of its sexp. This is useful for dealing with the case where you want to keep track of a value along with the format of the s-expression it was generated from, which allows you to maintain formatting details, comments, etc.

The s-expression representation of a With_text.t is the raw text, stored as an atom. The bin_io representation contains both the bin_io of the underlying value and the bin_io'd version of the raw text.

This is similar to but simpler than the With_layout module included above (via Sexp_intf.S), which gives you access to a fully parsed version of the s-expression, with attached comments and layout information, to allow you to build layout-preserving s-expression transformations.

The invariants of a x With_text.t are broken if the x value is mutated.

val sexp_of_t : ('a -> Sexplib.Sexp.t) -> 'a t -> Sexplib.Sexp.t
val of_value : ('a -> Sexplib.Sexp.t) -> 'a -> 'a t

Generates a t from the value by creating the text automatically using the provided s-expression converter.

val of_text : (Sexplib.Sexp.t -> 'a) -> ?filename:string -> string -> 'a t Or_error.t

Creates a t from the text, by first converting the text to an s-expression, and then parsing the s-expression with the provided converter.
