Sample project in OCaml using Dune

Building

To build the project using Dune you can run

dune build

This will build the project, the compiled files are located in the /_build/default/ directory.

During development, you can use dune watch mode

dune build --watch

This will rebuild the project every time you modify and save a project file.

We can run the executable from the project using

dune exec ex_main

Running tests can be done with the command

dune test

Project structure

The project includes three subparts

• lib a folder defining a library
• bin a folder containing an executable that uses the library defined in lib
• test a folder containing tests of the library defined in lib

Each folder contains a dune file, describing how the project should be built. The dune-project is the main dune file. It specifies metadata about the project.
