A toy OCaml builder

Introduction

denu is a toy OCaml builder that I build to learn how to build OCaml project manually.

As you can guess, denu is an anagram of dune (the de-facto OCaml builder).

Features

No configurations

denu takes no configurations. To compile a project, you would run

denu entry_file.ml

This would create an executable called entry_file.exe in the same folder. This is your compiled program.

No cache

Unlike dune, denu doesn't cache compilation result. Compilation starts from scratch on each invocation.

External libraries

Add a file called denu with packages name on each line and denu would link those packages for you.

See src/denu for example.

denu could compile itself

A builder should be able to compile itself.

Less than 200 lines of code

(excluding tests)
