Greetings Cameleers,

We’re back with a new installment in our opam deep-dives series!

Opam 103: Bootstrapping a New OCaml Project with opam

This time, we’re taking a step back to focus on a beginner-friendly guide to setting up a toy OCaml project with opam, dune, cmdliner, and alcotest.

This article is aimed at newer members of the ecosystem who may be wondering:

  • How do I structure an OCaml project from scratch?
  • How to best use opam in my dev workflow?
  • How do I write a minimal .opam file?
  • What about a fully fledged one?

We walk through the opam rationale and offer guidance for building your first opam-compliant package — the kind you can confidently pin and use locally before getting to publishing it.

As always, we hope this piece serves as a helpful reference for those onboarding into the opam and the OCaml ecosystem and getting their first taste of the tooling.
