core tutorial

This page shows how to call the root package and where to go instead for real work: the root package Luna-Flow/diff_bench contains only the template function hello.

Quick start

Inside the module, import the root package in moon.pkg:

import {
  "Luna-Flow/diff_bench",
}

Then call it:

test "root package" {
  let greeting = @diff_bench.hello()
  inspect(greeting.length(), content="20")
  inspect(greeting, content="hello from Luna-Flow")
}

Everyday tasks

There are none in this package. To compare decimal libraries, start with the dzmingli_vs_floating tutorial or the floating_vs_decmial_x tutorial.

Common pitfalls

• In a blackbox test the function must be qualified: @diff_bench.hello(). MoonBit 0.10 warns about the unqualified form.

Next steps

• core API and core design.
• The manual overview lists every package.
