OCaml Workshop

The OCaml Users and Developers Workshop brings together the OCaml community, including users of OCaml in industry, academia, hobbyists, and the free software community.

The meeting is an informal community gathering of users of the language, library authors, and developers, using and extending OCaml in new ways. The meeting will be held online this year.

This workshop was originally planned to take place in Jersey City, New Jersey, USA and was later changed to be held virtually.

Some Videos

A Declarative Syntax Definition for OCaml
In this talk, we present our work on a syntax definition for the OCaml language in the syntax definition formalism SDF3. SDF3 supports the high-level definition of concrete and abstract syntax through declarative disambiguation and definition of c...
A Simple State-Machine Framework for Property-Based Testing in OCaml
Since their inception, state-machine frameworks have proven their worth by finding defects in everything from the underlying AUTOSAR components of Volvo cars to digital invoicing systems. These case studies were carried out with Erlang’s commercia...
AD-OCaml: Algorithmic Differentiation for OCaml
AD-OCaml is a library framework for calculating mathematically exact derivatives and deep power series approximations of almost arbitrary OCaml programs via algorithmic differentiation. Unlike similar frameworks, this includes programs with side e...
API migration: compare transformed
In this talk we describe our experience in using an automatic API-migration strategy dedicated at changing the signatures of OCaml functions, using the Rotor refactoring tool for OCaml. We perform a case study on open source Jane Street libraries ...
Irmin v2
Irmin is an OCaml library for building distributed databases with the same design principles as Git. Existing Git users will find many familiar features: branching/merging, immutable causal history for all changes, and the ability to restore to an...
LexiFi Runtime Types
OCaml programmers make deliberate use of abstract data types for composing safe and reliable software systems. The OCaml compiler relies on the invariants imposed by the type system to produce efficient and compact runtime data representations. Be...
