Yappacino

This article is not detailed enough and needs to be expanded. Please help us by adding some more information.

Note: This page assumes that you are familiar with JavaScript, the concept of JavaScript supersets, and transpilation.

Yappacino is a JavaScript superset transpiled to JavaScript made by FaceDev featured in the video "I made a JavaScript superset" that makes you yap a lot.

Features

Yappacino, being a JavaScript superset transpiled to JavaScript, has all of the features and syntax that JavaScript has. However, it's recommended to use the Yappacino syntax.

Types

Yappacino has types and type annotations. However, type annotations are completely decorative and do absolutely nothing.

unsynchronised constant variable PI: Integer = 3.14;

Integers

The integer type in Yappacino is Integer. It's not actually a "true" integer type though due to JavaScript not having an integer type, and type annotations doing literally nothing.

unsynchronised constant variable PI: Integer = 3.14159265358979;
synchronised constant variable YappacinoIsBetterThanBussinX: Integer = complicated;
volatile mutable variable x: Integer = 1;

Strings

Strings in Yappacino are called Ligatures. Ligatures mean a thing used for tying, but the difference should be subtle enough.

stable mutable variable hello: Ligature = "Hello, World!";
unsynchronised constant variable rawLigature: Ligature = String.raw`
Bussin X
Bussin GriddyCode
Bussin Yappacino
Bussin Wattesigma
`;

Booleans

The NovemHeader or "megabool" is an extension of JavaScript's bool type with 9 states instead of two. When transpiled to JavaScript, the 9 states are put into the __BOOLEANS__ object/dictionary.

The basic true and false states are present with the addition of 7 more states. The other 7 states are just numbers ranging from 0.0001 to 0.0007 which necessitates the use of whatever the === and !== operators are as well as careful handling of comparing numbers to NovemHeader values.

Here is a table of the conversions of the NovemHeader members to JavaScript.

__BOOLEANS__
Yappacino	JavaScript
true	true
false	false
neither	0.0001
both	0.0002
maybe	0.0003
trueish	0.0004
falseish	0.0005
depends	0.0006
complicated	0.0007

Variables

Variables in Yappacino make you yap a lot. To declare a constant, you can do

constant variable x: Ligature = "Hello";

mutable is used instead of constant if you want to mutate the variable.

However for constants, you have to first specify whether it's synchronised or unsynchronised.

synchronised constants when assigned a value that is the same as that of another synchronised constant will assign its value to that constant when changed.

Example: (taken from "I made a JavaScript superset" by FaceDev)

synchronised constant variable x = "a";
synchronised constant variable y = "a";
x = { hello: true }

console.log(y) // { hello: true }

For mutable variables, there are also two keywords for it, volatile and stable.

Example: (taken from "I made a JavaScript superset" by FaceDev)

unsynchronised constant variable x = "a";
unsynchronised constant variable y = "a";
x = { hello: true }

console.log(y) // "a"

Functions

The syntax for a function declaration in Yappacino is:

-> returnType independent/dependent invariable/variable void/ratify function/subroutine name(arg1, arg2... argN : type1, type2... typeN) {
    ...
}

The types are reversed in both the function return type and the function parameter arguments.

Keyword	Meaning
independent	The function cannot be called from the program
dependent	The function can be called from the program
invariable	The function cannot be assigned to a variable
variable	The function can be assigned to a variable
subroutine	The function does not return a value

Classes

Classes in Yappacino are made with transient/transitory classification.

transient classification Person {
    extemporize (name: Ligature) {
        aforementioned.name = name;
    }
    
    -> Integer dependent invariable void async subroutine greet ? (){
        C:\Standard\System\io\format\print\ln("buzz");
    }
}

Keyword	Meaning
transient	The class can be initialized only once (optional)
transitory	(optional)
classification	The class keyword

Methods in Yappacino are declared the same as normal functions, but with a ? (question mark) between the method name and the parameter list.

aforementioned is used as a replacement for this and classes are constructed with extemporize.

Members

The recommended way to access the member of an object in Yappacino is to use a Windows path. An example of this is printing, which in JavaScript is console.log but in Yappacino, is:

C:\Standard\System\io\format\print\ln("helo");

For objects, the syntax is the object followed by a colon, preferably in all caps, followed by the member.

object:\level1\level2\level3

JavaScript	Yappacino
env.config()	ENV:\config()
console.log(arg1, arg2, arg3)	C:\Standard\System\io\format\print\ln(arg1, arg2, arg3)
map.get("string")	MAP:\get("Ligature")
obj.fields.name	obj:\fields\name

Conditional Statements

Yappacino supports two conditionals, stipulate and compeer as if and switch statements.

If statements

In Yappacino, if statements are made with stipulate and the else branches are made with otherwise.

yappacino/src/index.yap
47 48 49 50 51 52 53	stipulate (file === "node_modules") continue; stipulate (fileStat.isDirectory()) { res = await readDirRecursive(filePath, res); } otherwise stipulate (file.endsWith(".yap") || file.endsWith(".🗣️")) { res.push(filePath); }

In JavaScript...

yappacino/src/backup/yapped_index.js
61 62 63 64 65 66 67	if (file === "node_modules") continue; if (fileStat.isDirectory()) { res = await readDirRecursive(filePath, res); } else if (file.endsWith(".yap") || file.endsWith(".🗣️")) { res.push(filePath); }

Switch statements

In Yappacino, switch statements are declared with compeer with similar syntax to Rust.

compeer (x) {
    1 => C:\Standard\System\io\format\print\ln("one"),
    2 | 3 | 5 | 7 | 11 | 13 | 17 | 19 => {
        C:\Standard\System\io\format\print\ln("prime number");
        C:\Standard\System\io\format\print\ln("this is so bussin frfr nocap");
    },
    nonfulfillment => {
        C:\Standard\System\io\format\print\ln("What the hell is this?", x);
    }
}

The above code compiles down to:

switch (x) {
    case 1:
        console.log("one");
        break;
    case 2:
    case 3:
    case 5:
    case 7:
    case 11:
    case 13:
    case 17:
    case 19: {
        console.log("prime number");
        console.log("this is so bussin frfr nocap");
        break;
    }
    default: {
        console.log("What the hell is this?", x);
        break;
    }
}

nonfulfillment is the equivalent of default in JavaScript.

Loops

For loops

For loops in Yappacino are quite similar to that of Rust.

towards (i within start..end) {}
towards (i within start..m.end) {}

Imports

Imports in Yappacino are done through connotate and derives.

yappacino/src/index.yap
1 2 3	connotate { readdir, stat, mkdir, rm } derives "node:fs/promises"; connotate { join } derives "node:path"; connotate { parseArgs } derives "util";
