Agda.Syntax.Abstract
Contents
Description
The abstract syntax. This is what you get after desugaring and scope analysis of the concrete syntax. The type checker works on abstract syntax, producing internal syntax (Agda.Syntax.Internal).

Types are just expressions. Use this type synonym for hinting that an expression should be a type.

Instances
data TypedBinding Source #
A typed binding. Appears in dependent function spaces, typed lambdas, and
telescopes. It might be tempting to simplify this to only bind a single
name at a time, and translate, say, (x y : A) to (x : A)(y : A)
before type-checking. However, this would be slightly problematic:
- We would have to typecheck the type
Aseveral times. - If
Acontains a meta variable or hole, it would be duplicated by such a translation.
While 1. is only slightly inefficient, 2. would be an outright bug.
Duplicating A could not be done naively, we would have to make sure
that the metas of the copy are aliases of the metas of the original.

A user pattern together with an internal term that it should be equal to after splitting is complete. Special cases: * User pattern is a variable but internal term isn't: this will be turned into an as pattern. * User pattern is a dot pattern: this pattern won't trigger any splitting but will be checked for equality after all splitting is complete and as patterns have been bound. * User pattern is an absurd pattern: emptiness of the type will be checked after splitting is complete. * User pattern is an annotated wildcard: type annotation will be checked after splitting is complete.

A name in a binding position: we also compare the nameConcrete when comparing the binders for equality.
With --caching on we compare abstract syntax to determine if we can
reuse previous typechecking results: during that comparison two
names can have the same nameId but be semantically different,
e.g. in {_ : A} -> .. vs. {r : A} -> ...
