module Build: sig
.. end
type
t
val empty : t
Empty builder (position=Stop
)
val to_pos : t -> Position.position
Extract current position
val of_pos : Position.position -> t
Start from a given position
val prefix : Position.position -> t -> t
Prefix the builder with the given position
val suffix : t -> Position.position -> t
Append position at the end
All the following builders add elements to the end
of the builder. This is useful when a term is traversed and
positions of subterms are needed, since positions are
easier to build in the wrong order (leaf-to-root).
val type_ : t -> t
val left : t -> t
Add left
at the end
val right : t -> t
Add left
at the end
val body : t -> t
val head : t -> t
val arg : int -> t -> t
Arg position at the end
