package override

override 0.3.0, 2020-05-18

• support for OCaml 4.11.0

• relies on metapp and metaquot. ppxlib and ppx_deriving are not dependencies anymore.

override 0.2.2, 2019-09-27

• support for OCaml 4.09.0

• compatible with the latest versions of ppxlib and ppx_deriving

override 0.2.1, 2019-07-04

• attributes applied on [%%types] are applied once by declaration group. (Previously, attributes were applied to each types in a group, leading ppxlib's deriving to make n * n expansions for a group of n types -- one for each type/attribute pair).

override 0.2.0, 2019-07-01

• compatibility with OCaml 4.08.0

• remove dependency to ppx_tools

• add examples/typedtree_collect_texp_apply

• bootstrapped equivalence checking for Parsetree.core_type: matching between types for applying rewriting rules is now complete, and is implemented by overriding Parsetree and deriving eq. The former incomplete equivalence checking is used to bootstrap.

• support aliases even if the target module is defined in the same module (we do not take declaration order into account yet, so there can be wrong shadowings, and even loops, even if we suppress the trivial ones).

• renamed types are substituded globally in mutually recursive type definitions.

override 0.1.0, 2019-05-09

• generalizes ppx_import by allowing a whole module to be imported with all its types, possibly with annotations.

• module overriding: mechanization of Gabriel Scherer's post on Gagallium blog http://gallium.inria.fr/blog/overriding-submodules/

• type rewriting: types can be systematically annotated, substituted, renamed, or removed. Transformations such as those that are described in the comments of ast/ast.ml in ppxlib sources can be mechanized.
