Adding "resources" section

[mauroexe]

Hey Alixander!

I've been doing lots and lots of diagrams and I struggled with something...

When you define your objects, there's no way to keep them invisible and use them later... I came across an idea of creating a section of resources; just like D2 classes but those "resources" could be based on classes too.

To help you understand the idea better, I share you a link to a diagraming tool that a friend of mine found. This tool has a resources section (coincidently LOL).

If you can implement that "resources" behavior, D2 will be strong enough to have no competitors, I have all the faith in your efforts; I wish I had the time to spare helping you coding it.

Imagine if the next scenario could be possible:

FILE: styles.d2

classes: {
  dog: {
    shape: circle
  }
  male: {
    style.fill: brown
    style.fill: brown
    style.font-color:white
  }
  female: {
    style.fill: orange
  }
}

FILE: dogs.d2

resources: {
  dog1: Frido {
    class: [dog; male]
  }
  dog2: Snoopy {
    class: [dog; male]
  }
  dog3: Paulette {
    class: [dog; female]
  }
}

FILE: houses.d2

resources: {
  my-house: {
    label: "Home"
  }
  friends-house: {
    label: "Friend's House"
  }
}

FILE: diagram.d2

...@styles
...@dogs
...@houses

relations: {
  my-house: {
    dog1 -- dog3: "Couple"
  }
  friends-house: {
    dog2
  }
}

The previous example should compile into something like this:

It really improves the readability of what really matters: the relations, ¿Don't you think?

¿What do you say, can you implement it sometime in the future?

vars should actually be flexible enough to do this. but needs some compiler work to make it work. good suggestion, thank you
