Implicit Arguments

Here we store the implicit arguments. Notice that we are outside the kernel, which knows nothing about implicit arguments.

An implicits_list is a list of positions telling which arguments of a reference can be automatically inferred

type argument_position =
  1. | Conclusion
  2. | Hyp of int
type implicit_explanation =
  1. | DepRigid of argument_position
    (*

    means that the implicit argument can be found by unification along a rigid path (we do not print the arguments of this kind if there is enough arguments to infer them)

    *)
  2. | DepFlex of argument_position
    (*

    means that the implicit argument can be found by unification along a collapsible path only (e.g. as x in (P x) where P is another argument) (we do (defensively) print the arguments of this kind)

    *)
  3. | DepFlexAndRigid of argument_position * argument_position
    (*

    means that the least argument from which the implicit argument can be inferred is following a collapsible path but there is a greater argument from where the implicit argument is inferable following a rigid path (useful to know how to print a partial application)

    *)
  4. | Manual
    (*

    means the argument has been explicitly set as implicit.

    *)

We remember various information about why an argument is inferable as implicit

We also consider arguments inferable from the conclusion but it is operational only if conclusion_matters is true.

declare_manual_implicits local ref enriching l Manual declaration of which arguments are expected implicit. If not set, we decide if it should enrich by automatically inferd implicits depending on the current state. Unsets implicits if l is empty.

val declare_manual_implicits : bool -> Names.GlobRef.t -> ?enriching:bool -> manual_implicits -> unit

If the list is empty, do nothing, otherwise declare the implicits.
