lemonScript

Introduction

One morning, a young Khalid awoke and decided to finish his A.I assignment. “Gosh, I just hate python more than life itself” he muttered as he typed with a sour face. At that moment, he looked at the lemon pulp he has been collecting for the past 5 years due to his midnight lemon snack addiction. At that moment, he decided to call his much smarter and superior friend David to write him a language that everyone could enjoy. So, David formed a team with Brent, Julian, Justin, Raul, and Khalid with the intent to create a language for all lemon enthusiasts. The stage has been set. lemonScript was to be a self-explanatory, statically-typed, esoteric language with the sole purpose of saving people who had a sour taste in their mouth from using popular languages.

Features

• Statically typed language
• Static scoping!
• Switch statements using keywords pick()
• Easily defined blocks of code seperated by the words BEGIN JUICING and END JUICING
• Declare functions with "When life gives you lemons try (return type) name()"
• Single line comments with ( *)
• Multiple line comments with ( *) (* )
• AND SO MUCH MORE TASTY FEATURES ITS A BITTER PILL TO SWALLOW TO LET GO OF THE FAMOUS PYTHON, BUT GIVE LEMONSCRIPT A TRY! ITS REFRESHING!

Types

JavaScript	lemonScript
String	pulp
Number	slice (for integers) or dontUseMeForEyeDrops (for floats)
Boolean	taste
const	lemonStain

Types of Static Semantic Errors

• Type mismatch
• Assignment to constant variable
• Continue/Break can only be used in a loop
• Number of arguments when calling a function
• Arguments passed into a function has the correct types
• Is callable
• Returns something
• Returns nothing
• The return type is correct
• Not inside a function
• Is a number
• Is an integer
• Is a boolean
• Is an array
• Is a dictionary
• All elements in an array has the same type
• All keys are unique
• Keys and Values have the correct type

Variable Declaration and Assignment

JavaScript	lemonScript
let x = 10;	slice x = 10
let y = "Lemons are great";	pulp y = "Lemons are great"
let z = 4.20;	dontUseMeForEyeDrops z = 4.20
let a = true;	taste a = sweet
const c = "blue";	lemonStain pulp c = "blue"

Built In Functions

lemonScript	JavaScript
pour(“Hello World”)	console.log("Hello, World!");

Function Declarations

lemonScript	JavaScript
When life gives you lemons try (return type) *name*() BEGIN JUICING statements END JUICING	function name([param[, param,[..., param]]]) { [statements] }

Comments

JavaScript	lemonScript
//this is a single line comment	( *)this is a comment
/*this is a multi-line comment	( *)this is a multi-comment(* )

Arithmetic

• sum = 2 + 4
• difference = 2 - 4
• multiplication = 2 * 4
• division = 4 / 2
• exponents = 4 ^ 2 *note we can change this to ** or something else
• modulus = 4 % 2

If/Else	Squeeze the lemon if(x == 10) BEGIN JUICING pour(“Number is 10”) END JUICING Keep juicing if(x == 20) BEGIN JUICING pour(“Number is 10”) END JUICING Toss the lemon and do BEGIN JUICING pour(“Number is not 10 or 20”) END JUICING	if (x == 10) { console.log(“Number is 10”) } else if (x == 20) { console.log(“Number is 20”) } else { console.log(“Number is not 10 or 20”) }
For Loops	forEachLemon (slice i = 0; i < 5; i++) BEGIN JUICING pour(“Number: ” + i) END JUICING	for (i = 0; i < 5; i++) { console.log(“Number: ” + i) }
While Loops	Drink the lemonade while (x > 0) BEGIN JUICING pour(x) x-- END JUICING	while (x > 0) { console.log(x) x-- }

Example Programs

lemonScript	JavaScript
When life gives you lemons try noLemon helloWorld() BEGIN JUICING pour(“Hello World”) END JUICING	function helloWorld() { console.log(“Hello World”) }

Adding Two Numbers

lemonScript	JavaScript
When life gives you lemons try slice add(slice a, slice b) BEGIN JUICING you get lemonade and a + b END JUICING	function add(a, b) { return a + b }

Switch Statements

lemonScript	JavaScript
slice even = 4 pulp twofoursixeight Pick (even) BEGIN JUICING lemonCase 2 twofoursix = "two" chop lemonCase 4 twofoursix = "four" chop lemonCase 6 twofoursix = "six" chop citrusLimon twofoursix = "eight" END JUICING pour(“Our result is ” + twofoursix)	let even = 4; let twofoursixeight; switch (even) { case 2: twofoursix = "two"; break; case 4: twofoursix = "four"; break; case 6: twofoursix = "six"; break; default: twofoursix = "Eight"; } console.log(“Our result is ” + twofoursix);

lemonScript	JavaScript
When life gives you lemons try slice fibonacci(slice num) BEGIN JUICING Squeeze the lemon if(num == 0) BEGIN JUICING you get lemonade and 0 END JUICING Squeeze the lemon if(num == 1 || num == 2) BEGIN JUICING you get lemonade and 1 END JUICING you get lemonade and fibonacci(num - 2) + fibonacci(num - 1) END JUICING	function fibonacci(num){ if(num == 0){ return 0; } if(num == 1 || num == 2){ return 1 } return fibonacci(num - 2) + fibonacci(num - 1) }

Class Example

lemonScript

JavaScript

Limon Car BEGIN JUICING plant(pulp name ,slice year) BEGIN JUICING thisLemon.name = name thisLemon.year = year END JUICING When life gives you lemons try slice getYear() BEGIN JUICING you get lemonade and thisLemon.year END JUICING END JUICING Car myCar = seed Car("Ford",2014) Limon Ferrari branches Car BEGIN JUICING plant(slice year) BEGIN JUICING thisLemon.name = "F8 Spider" thisLemon.year = year END JUICING END JUICING

class Car { constructor(name, year) { this.name = name; this.year = year; } getYear(){ return this.year } } myCar = new Car("Ford", 2014); class Ferrari extends Car { constructor(year) { this.name = "F8 Spider"; this.year = year; } }
