Description

Annotating an algebraic data type definition with [@@deriving visitors { ... }] causes visitor classes to be automatically generated. A visitor is an object that knows how to traverse and transform a data structure.

Published: 16 Nov 2025

README

An OCaml syntax extension (technically, a ppx_deriving plugin) which generates object-oriented visitors for traversing and transforming data structures.

Here is the documentation of the latest released version.

The easiest way of installing the latest released version of this package is via opam, the OCaml package manager.

opam update
opam install visitors

To install the latest development version, also via opam, please proceed as follows:

  git clone https://gitlab.inria.fr/fpottier/visitors.git
  cd visitors
  make pin

To install the latest development version, outside of opam, please proceed as follows:

  git clone https://gitlab.inria.fr/fpottier/visitors.git
  cd visitors
  opam install . --deps-only
  make install
