Module Printtyp

val namespaced_ident : Shape.Sig_component_kind.t -> Ident.t -> string
val tree_of_path : Path.t -> Outcometree.out_ident
val string_of_path : Path.t -> string
val type_path : Path.t Format_doc.printer

Print a type path taking account of -short-paths. Calls should be within wrap_printing_env.

module Out_name : sig ... end
type namespace := Shape.Sig_component_kind.t option
val strings_of_paths : namespace -> Path.t list -> string list

Print a list of paths, using the same naming context to avoid name collisions

val raw_row_desc : Format_doc.formatter -> Types.row_desc -> unit
val raw_type_expr : Format_doc.formatter -> Types.type_expr -> unit
val raw_field : Format_doc.formatter -> Types.row_field -> unit
val string_of_label : Types.arg_label -> string
val wrap_printing_env : error:bool -> Env.t -> (unit -> 'a) -> 'a
module Naming_context : sig ... end
module Conflicts : sig ... end

The Conflicts module keeps track of conflicts arising when attributing names to identifiers and provides functions that can print explanations for these conflict in error messages

val reset : unit -> unit

Print out a type. This will pick names for type variables, and will not reuse names for common type variables shared across multiple type expressions. (It will also reset the printing state, which matters for other type formatters such as prepared_type_expr.) If you want multiple types to use common names for type variables, see prepare_for_printing and prepared_type_expr.

val modality : ?id:(Format_doc.formatter -> unit) -> 'a Mode.Modality.Axis.t -> Format_doc.formatter -> 'a -> unit

Prints a modality. If it is the identity modality, prints id, which defaults to nothing.

val prepare_for_printing : Types.type_expr list -> unit

prepare_for_printing resets the global printing environment, a la reset, and prepares the types for printing by reserving names and marking loops. Any type variables that are shared between multiple types in the input list will be given the same name when printed with prepared_type_expr.

val add_type_to_preparation : Types.type_expr -> unit

add_type_to_preparation ty extend a previous type expression preparation to the type expression ty

val prepared_type_expr : Types.type_expr Format_doc.printer

The function prepared_type_expr is a less-safe but more-flexible version of type_expr that should only be called on type_exprs that have been passed to prepare_for_printing. Unlike type_expr, this function does no extra work before printing a type; in particular, this means that any loops in the type expression may cause a stack overflow (see #8860) since this function does not mark any loops. The benefit of this is that if multiple type expressions are prepared simultaneously and then printed with prepared_type_expr, they will use the same names for the same type variables.

val tree_of_type_scheme : Types.type_expr -> Outcometree.out_type
val prepared_type_scheme : Types.type_expr Format_doc.printer
val shared_type_scheme : Types.type_expr Format_doc.printer

shared_type_scheme is very similar to type_scheme, but does not reset the printing context first. This is intended to be used in cases where the printing should have a particularly wide context, such as documentation generators; most use cases, such as error messages, have narrower contexts for which type_scheme is better suited.

val functor_parameters : sep:unit Format_doc.printer -> ('b -> Format_doc.formatter -> unit) -> (Ident.t option * 'b) list -> Format_doc.formatter -> unit

Print a list of functor parameters while adjusting the printing environment for each functor argument.

Currently, we are disabling disambiguation for functor argument name to avoid the need to track the moving association between identifiers and syntactic names in situation like:

got: (X: sig module type T end) (Y:X.T) (X:sig module type T end) (Z:X.T) expect: (_: sig end) (Y:X.T) (_:sig end) (Z:X.T)
