Getting Started with OCaml Jupyter

Welcome to the exciting world of OCaml Jupyter, where you can combine the functional programming power of OCaml with the interactive capabilities of Jupyter notebooks! This guide will walk you through the installation process, usage examples, and some troubleshooting tips to get you up and running smoothly.

What is OCaml Jupyter?

OCaml Jupyter is an OCaml kernel designed for Jupyter notebooks. It provides a Read-Eval-Print Loop (REPL) environment that supports Markdown, HTML documentation, LaTeX formulas via MathJax, and image embedding, making it a powerful tool for both learning and development.

Getting Started

Before using OCaml Jupyter, you need the required libraries installed. Depending on your operating system, follow the instructions below:

• For Debian or Ubuntu:

  sudo apt-get install -y zlib1g-dev libffi-dev libgmp-dev libzmq5-dev

• For RHEL or CentOS:

  sudo yum install -y epel-release
  sudo yum install -y zlib-devel libffi-dev gmp-devel zeromq-devel

• For Mac OS X:

  brew install zlib libffi gmp zeromq

Installing OCaml Jupyter

Once you have the libraries installed, you can install OCaml Jupyter using OPAM:

pip install jupyter
opam install jupyter
grep topfind ~/.ocamlinit
echo #use topfind;; >> ~/.ocamlinit
grep Topfind.log ~/.ocamlinit
echo Topfind.log:=ignore;; >> ~/.ocamlinit
ocaml-jupyter-opam-genspec
jupyter kernelspec install [ --user ] --name ocaml-jupyter-$(opam var switch) $(opam var share)/jupyter

If you encounter permission errors during installation, add the `–user` option or run the command with `sudo`.

Running Jupyter Notebook

Now you can start the Jupyter notebook server by running:

jupyter notebook

Usage Examples

OCaml Jupyter supports various functionalities such as code completion and inspection through the merlin library. Here are some useful links to example notebooks:

• Introduction to OCaml Jupyter
• DuckDuckGo Word Description
• Find more examples at docker-ocaml-jupyter-datascience.

Code Completion and Inspection

The interactive notebook also provides code completion and inspection powered by merlin, making it easier to write and debug your OCaml code.

Exporting Notebooks

You can convert your OCaml notebooks to various formats such as HTML or Markdown using the following command:

jupyter nbconvert --to html notebooks/introduction.ipynb

Troubleshooting

• Ensure that all dependencies are installed properly. Refer back to the installation instructions above.
• If the Jupyter notebook does not launch, check your terminal for error messages and ensure you are in the correct directory.
• For code completion issues, make sure a `.merlin` file is available in your notebook directory for proper functionality.
• If you encounter permission issues, consider using the `–user` option during installation or running commands with `sudo`.
