We, Jane Street ppx developers, are glad to announce the public availability of the [ppxlib project](https://github.com/ocaml-ppx/ppxlib). This project is the merge of several ppx-related repositories, including [ppx\_core](https://github.com/janestreet/ppx_core), [ppx\_driver](https://github.com/janestreet/ppx_driver), [ppx\_metaquot](https://github.com/janestreet/ppx_metaquot), and [ppx\_type\_conv](https://github.com/janestreet/ppx_type_conv). As such, ppxlib contains all the core elements one needs to develop ppx rewriters. While this is not the first project released as open source by Jane Street, this one is slightly different as the whole development now happens on github. In particular, we are using a PR-based workflow and will gladly add external contributors to the project (see [details](https://github.com/ocaml-ppx/ppxlib/blob/master/CONTRIBUTING.md)). We are moving to this workflow with the hope that it will make the collaboration with other open source projects easier. The project is currently released as 0.2.0 in opam. We are planning to make some changes before the 1.0 release, most notably adding support for [view patterns](https://github.com/ocaml-ppx/ppx_view) and improving the documentation. Contributions are warmly welcome! --- _[View the full topic](https://discuss.ocaml.org/t/ann-ppxlib-jane-street-ppx-infrastructure-now-on-github/1876)._
