Modularizing your project

A Tonto project consists of all Tonto files opened in your workspace, automatically. Due to that fact, by default every Tonto project is already modularized, the only effort needed is to create different files for each package.

The first step to modularize our University model could be creating a package for our custom datatypes called CoreDatatypes. Create a new file called CoreDatatypes.tonto, and extract the code from the PersonPhases package:

package CoreDatatypes

datatype PhoneNumber {
  countryCode: int [1]
  bodyNumber: int [1]
}

datatype int specializes number

enum EyeColor {
  Blue,
  Green,
  Brown,
  Black
}

In order to make our model work again, we need to go back to the PersonPhases package and add an import for our datatypes:

import CoreDatatypes

package PersonPhases
// Rest of package content...

In addition, we can go back to the University model, and create its own package instead of using the PersonPhases package for its declaration.

In Tonto, we have:

import CoreDatatypes
import PersonPhases
package University

category Organization
kind University specializes Organization {
