# Chatterbox

Generates text based on a context-free grammar.

For example, given this grammar:

```text

start -> "The" _  _ "is" _  "." | "A" _  _  "." ;

noun -> "house" | "cat" ;

adj -> "green" | "big" ;

```

will generate one of the following:

```text

The house is green.

The house is big.

The cat is green.

The cat is big.

A big house.

A big cat.

A green house.

A green cat.

```

The full example listing:

```javascript

const { parse, validate, generate } = require("@aradzie/chatterbox");

const grammar = parse(`

start ->

    "The "  " is "  "."

  | "A "  " "  "."

  ;

noun ->

    "house"

  | "cat"

  ;

adj ->

    "green"

  | "big"

  ;

`);

validate(grammar);

console.log(generate(grammar));

```

This project is based on book `Dive Into Python` which included an example of how to generate

mock philosophy based on a context-free grammar. I had a good laugh reading mock Kant passages:

> The noumena are the clue to the discovery of, therefore,our judgements.

> I assert, certainly, that the architectonic of human reason is just as necessary as, therefore,

> our concepts; still, the things in themselves are the clue to the discovery of, in the case of

> necessity, the never-ending regress in the series of empirical conditions.

> It must not be supposed that the paralogisms, irrespective of all empirical conditions,

> can be treated like the thing in itself, as is shown in the writings of Galileo.

> In the case of the transcendental aesthetic, the Categories are just as necessary as,

> in other words, our faculties, by virtue of pure reason.

> (The phenomena can not take account of the Ideal of practical reason, and the Ideal of practical

> reason is a representation of time.)

> Necessity would thereby be made to contradict, in the case of the thing in itself,

> the thing in itself, yet the transcendental unity of apperception constitutes the whole content

> for philosophy.

I ported the original grammar XML files to a new syntax which is more readable.

The files are available in the [grammar](./grammar) directory.
