Ocaml_typing.Printtyp
SourcePrint a type path taking account of -short-paths
. Calls should be within wrap_printing_env
.
type namespace := Shape.Sig_component_kind.t option
Print a list of paths, using the same naming context to avoid name collisions
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
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
.
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
.
add_type_to_preparation ty
extend a previous type expression preparation to the type expression ty
The function prepared_type_expr
is a less-safe but more-flexible version of type_expr
that should only be called on type_expr
s 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.
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.

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)
