Minimalistic C inspired language

General structure

The program is a list of process calls and type definitions.

The language is line based, so every line is one of these.

A process call looks like this:

porky11

fn factorial (arg)
    loop (x = arg)
        if (x == 1)
            break 1
        else
            x * (repeat (x - 1))

print (factorial 5)

Basically, what I want to do is following. First I have a state. The state can generate a list of available events. This could look like this:

struct State;

impl State {
  fn get_events(&mut self) -> impl Iterator<Item = Event> {...}
}

Introduction

It's interesting to think about making programming lanugages more like natural languages. The problems with most existing approaches is, the langauge designers try to stick to grammatical structures of natural languages, but don't implement these structures into code directly. Instead they just implement a pretty simple program, which is basically just a traditional programming language, but with a mostly more verbose syntax of the natural language.

A more reasonable approach would be to define a programming language and only add benefits from natural language. The concepts from the natural langauges should be mapped to the programming language in a simple way. The english language will be used as reference, when needed.

So let's just start with the language design.

Motivation

• description of a fantasy world
• replayable adventure experience with many possibilities
• rather normal people living in a fantasy world
• realistic reactions in weird situations
• description of futuristic societies
• boys in the age, where they get interests in relationships, while still being more interested in action
• communicating some values, but with options not to accept them

Story

Introduction

You are a boy/girl living in the city. Now you are old enough to travel alone. Since you are a cyborg, you are interested in some island, which was famous for different kinds of technology, even cyborg extensions. Nowadays there's nothing going on anymore. It's just a small island, where some nature people live. Because of their era of prosperity, there also still live many different kinds of people of different races.

You assume it's going to be a relaxing vacation, where you explore the landscape and talk to native people there.
