Idea

The Name-Agda type represents quoted names, i.e. they are an abstract syntactic representation of terms. Agda provides primitive functions to manipulate them, giving them an equality and ordering. A closed term can be converted to a quoted name by means of the quote keyword, e.g. quote bool.

Definition

postulate
  Name-Agda : UU lzero

{-# BUILTIN QNAME Name-Agda #-}

primitive
  primQNameEquality : Name-Agda → Name-Agda → bool
  primQNameLess : Name-Agda → Name-Agda → bool
  primShowQName : Name-Agda → String
  primQNameToWord64s : Name-Agda → Word64 × Word64
  primQNameToWord64sInjective :
    (a b : Name-Agda) → primQNameToWord64s a ＝ primQNameToWord64s b → a ＝ b

Examples

_ : primQNameLess (quote bool) (quote unit) ＝ true
_ = refl

_ : primShowQName (quote bool) ＝ "foundation-core.booleans.bool"
_ = refl
