The OCaml Planet

We will present a property-based testing framework for OCaml that leverages the power of QuickChick, a popular and mature testing plugin for the Coq proof assistant, by automatically constructing a extraction-based shim between OCaml and Coq. That...

If values of a given type are stored on disk, or are sent between different executables, then changing that type or its serialization can result in versioning issues. Often such issues are resolved by either making the deserializer more permissiv...

OCaml relies on a type-agnostic object representation centred around values which unify odd integers and aligned pointers. The last bit of a value distinguishes the two variants: zero indicates a pointer on the OCaml heap, while one encodes a ta...

We present Love, a smart contract language embedded in the Dune Network blockchain. It benefits from an OCaml-like syntax and a system-F inspired type system. Love has been used for deploying complex services such as games, ERC20s, atomic swaps, e...

In this talk, we will present opam-bin, an Opam plugin that builds Binary Opam packages on the fly, to speed-up reinstallation of pack- ages. opam-bin also creates Opam Repositories for these binary pack- ages, to make them easy to share with othe...

The multicore branch of OCaml adds support for effect handlers. In this talk, we report our experiences with effects, both from converting existing code, and from writing new code. Converting the Angstrom parser from a callback style to effects gr...

Professor Xavier Leroy -- the primary original author and leader of the OCaml project -- reflects on 25 years of the OCaml language at his OCaml Workshop 2021 keynote speech.

In this talk, we will introduce a new tool called digodoc, that builds a graph of an opam switch, associating files, libraries and opam packages into a cyclic graph of inclusions and dependencies. We will then explain how we used that tool to buil...

This talk describes the process of generating documentation for every version of every package that can be built from the opam repository, and how it is presented as a single coherent website that is continuously updated as new packages are releas...

Regular CI systems are optimised for workloads that do not require stable performance over time. This makes them unsuitable for running performance benchmarks. current-bench provides a predictable environment for performance benchmarks and a UI...
