Module SectionSource

Kernel implementation of sections.

Sourcetype 'a t

Type of sections with additional data 'a

Sourceval depth : 'a t -> int

Number of nested sections.

Sourceval map_custom : ('a -> 'a) -> 'a t -> 'a t

Modify the custom data

Manipulating sections
Sourcetype section_entry =
  1. | SecDefinition of Names.Constant.t
  2. | SecInductive of Names.MutInd.t
Sourceval open_section : custom:'a -> 'a t option -> 'a t

Open a new section with the provided universe polymorphic status. Sections can be nested, with the proviso that polymorphic sections cannot appear inside a monomorphic one. A custom data can be attached to this section, that will be returned by close_section.

Sourceval close_section : 'a t -> 'a t option * section_entry list * Univ.ContextSet.t * 'a

Close the current section and returns the entries defined inside, the set of global monomorphic constraints added in this section, and the custom data provided at the opening of the section.

Extending sections
Sourceval push_local : 'a t -> 'a t

Extend the current section with a local definition (cf. push_named).

Sourceval push_context : (Names.Name.t array * Univ.UContext.t) -> 'a t -> 'a t

Extend the current section with a local universe context. Assumes that the last opened section is polymorphic.

Sourceval push_constraints : Univ.ContextSet.t -> 'a t -> 'a t

Extend the current section with a global universe context. Assumes that the last opened section is monomorphic.

Sourceval push_constant : poly:bool -> Names.Constant.t -> 'a t -> 'a t

Make the constant as having been defined in this section.

Sourceval push_inductive : poly:bool -> Names.MutInd.t -> 'a t -> 'a t

Make the inductive block as having been defined in this section.

Retrieving section data
Sourceval all_poly_univs : 'a t -> Univ.Level.t array

Returns all polymorphic universes, including those from previous sections. Earlier sections are earlier in the array.

NB: even if the array is empty there may be polymorphic constraints about monomorphic universes, which prevent declaring monomorphic globals.

Sourcetype abstr_info = private {
  1. abstr_ctx : Constr.named_context;
    (*

    Section variables of this prefix

    *)
  2. abstr_subst : Univ.Instance.t;
    (*

    Actual names of the abstracted variables

    *)
  3. abstr_uctx : Univ.AUContext.t;
    (*

    Universe quantification, same length as the substitution

    *)
}

Data needed to abstract over the section variable and universe hypotheses

Sourceval empty_segment : abstr_info

Nothing to abstract

Sourceval segment_of_constant : Environ.env -> Names.Constant.t -> 'a t -> abstr_info

Section segment at the time of the constant declaration

Sourceval segment_of_inductive : Environ.env -> Names.MutInd.t -> 'a t -> abstr_info

Section segment at the time of the inductive declaration

Sourceval replacement_context : Environ.env -> 'a t -> Opaqueproof.work_list

Section segments of all declarations from this section.

Sourceval is_in_section : Environ.env -> Names.GlobRef.t -> 'a t -> bool
