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.

Added to opam-repository:

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

Build status

Results of building visitors with each compiler on check.ci.ocaml.org, run of against opam-repository 7cdc698. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
