If you are new to the OCaml programming language and the community at large, Welcome! and take a seat as I take you on a little tour of the OCaml community.

About OCaml

OCaml is a general-purpose, high-level, multi-paradigm programming language that extends the Caml dialect of ML with object-oriented features. And somebody says "English, please....". Relax, I'll break it down so you can understand it better:

General purpose means OCaml can be used to write all sorts of programs, not just a specific type like web applications or data analysis.

High-level, mean it’s designed to be easy for humans to read and write. It abstracts away many details of the computer’s operation, like memory management.

Multi-paradigm feature means it supports different styles of programming (called “paradigms”). So, you can write code in the way that’s most suitable for your problem.

Extend the Caml dialect of ML means that OCaml is based on an older language called Caml, which is a variant of another language called ML (Meta Language). It has all the features of Caml, but also adds new ones.

Object-oriented features mean that one of the paradigms it supports is object-oriented programming, a style where you define “objects” that have properties and behaviors and create programs by making these objects interact.

So, in simpler terms, OCaml is like a multi-tool. It’s easy to use, can be used in many ways, and has a lot of features that make it powerful for writing software. It’s based on older languages but adds the ability to program using “objects”, a common style in many modern languages.

The OCaml Community

The OCaml Community is diverse and worldwide. One of the main benefits of our community is the ability to easily reach each other. Mailing lists and web forums are the most common ways people interact, although you will always find users on IRC, and around the web.

Interacting with the OCaml Community

There are several ways you can engage with the OCaml community. Most of them are listed below:

  • GitHub: Here you can open bug reports and feature requests on the OCaml compiler.
  • Discuss Forums: Ask and answer questions, share and discuss OCaml-related articles and posts, let people know about your projects, and find collaborators.
  • Discord: Chat with other members of the community.
  • Twitter: Catch up with some of the latest announcements and events from the community.
  • Mastodon: The or Mastodon homeservers are both popular choices among the OCaml community.
  • IRC Chat: Chat with other members of the community at #ocaml on the Libera Chat IRC network.
  • Stack Overflow: Ask and help answer OCaml questions.
  • Matrix Chat: Chat with the OCaml community in the #ocaml-lang Matrix chat room, or join the #ocaml-space Matrix space.
  • Reddit: Join the OCaml subreddit to post discussions and memes, talk about your projects, and share interesting articles and news from the web.
  • Mailing List: Share experience, exchange ideas and code, and discuss applications of the OCaml language.

OCaml Workshops and Meetups

The OCaml community organizes workshops and meetups around the world. These events provide opportunities for OCaml enthusiasts to learn, share, and collaborate. Some of the past workshops were held in Seattle, Ljubljana, Berlin, St. Louis, Oxford, Nara, Vancouver, Gothenburg, Boston, Copenhagen, Paris, and Grenoble.

OCaml Jobs and Internships

The OCaml community also provides a space where groups, companies, and organizations can advertise their projects directly to the OCaml community. There are also OCaml Community Outreachy Internship Projects.

My Role as an Intern

Interning with OCaml has been very exciting and challenging. I've learned a lot so far and I'm still learning, thanks to my mentors and the resources provided by the community and the internet.

I was selected for the internship to work on the project "Improving the GUI experience for OCaml users". GUI means Graphical User Interface. A Graphical User Interface (GUI) is a digital platform that allows users to interact with visual elements like icons, buttons, and menus. The visuals in a GUI provide pertinent information to the user and indicate possible actions they can perform.

Precisely, I've been working on improving the GUIs in the Bogue library. I've worked on a bogue counter, which just increments and decrements count. I'm also working on a bogue countdown timer, which counts down a set time value when the start button is pressed, pauses it when the pause button is pressed, and resets the countdown when the reset button is pressed.

If you wish to learn more about this interesting language, OCaml, you can simply dive into the learning section of the website here. You'll get to learn the basic syntax, expressions, and even how to get started.


The OCaml community is a vibrant and diverse group of developers, libraries, tools, and frameworks built around the OCaml programming language. Whether you’re a seasoned developer or a beginner, the OCaml community is a great place to learn, share, and collaborate. So why wait? Dive in and become a part of this amazing community!
