Talks
Dune Package Management
Speaker: Ali Caglayan
Abstract: Dune package management is a project with the goal of teaching dune how to build and use opam packages. It has been in active development since 2023, and has started to take shape into something more polished and useful. Although it is still considered it experimental at this stage, I will discuss what is possible with it today (relocatable compiler, lockless building, OxCaml support), discuss some of the features we are currently working on (in-and-out, dev-tools), and finally give a glimpse of the road to stability.
Opam’s Nix system dependency mechanism
Speaker: Ryan Gibb
Abstract: The OCaml language package manager, Opam, has support for interfacing with system package mangers to provide dependencies external to the language. Supporting Nix required re-thinking the abstractions used to interface with traditional package managers, but enables using Opam for development easily whilst benefitting from Nix’s reproducible system dependencies. This provides one example of how Nix interfaces with other software development and deployment technologies.
