type t

val count : t -> int

Number of variables in the context.

val push_local : string -> Term.typ -> t -> t

push_local name typ gamma

Add the local variable with name and typ to the context.

Precondition

name <> ""

val type_of_literal : Term.Value.t -> t -> Term.typ

val type_of_variable : int -> t -> Term.typ

type_of_variable idx gamma

Return the type of the variable idx. idx is the De Bruijn index i.e. and index of 0 points to the last variable and an index of count gamma - 1 points to the first variable.

val definition_term : int -> t -> Term.t option

definition_term idx gamma

If the variable idx has a definition, then return it. Otherwise return None.

val context : t -> Gamma.t

val expand : Term.t -> t -> Term.t

val is_hole : int -> t -> bool

val value : int -> t -> Term.t option

val fill_hole0 : int -> Term.t -> bool -> t -> t
