Your First Program

To begin writing OsomarScript code, create a new file with a .os extension and start coding. Here's a simple "Hello, World!" program:

// hello.os
ctm("Hello World") jajaja

Language Basics

Syntax

• Comment: //
• Statement End: jajaja
• Code Block Start: "🃏
• Code Block End: 🃏"

Data Types

• number: Numeric data type for integers and floating-point numbers.
• string: Textual data enclosed in double quotes.
• falso: Logical data type representing False
• verdad: Logical data type representing true
• sepa dios: Represents an intentional absence of any value (null).

Variables

Variables are declared using the Ei keyword, and can be initalized when declared.

// Uninitialized variable
Ei x jajaja

// Initialized variable
Ei y es 10 jajaja

Operators

• Arithmetic Operators: +, -, *, /
• Comparison Operators: ==, !=, >, <, >=, <=
• Logical Operators: &&, ||
• Assignment Operator: es

Control Structures

While loop

• Executes a block of code wrapped in "🃏 🃏" as long as the condition inside () evaluates to true.

• Declared using the no digas mamadas mientras keyword.

• Break out of the block of code with the keyword mamo

no digas mamadas mientras (condition) "🃏

  //Code

🃏"


//Infinite loop with break keword
no digas mamadas mientras (verdad) "🃏

  ctm("start") jajaja //will run

  mamo jajaja //break out of loop

  ctm("end") jajaja //won't run

🃏"

If Statement

• The if statement allows you to execute a block of code wrapped in "🃏 🃏" conditionally based on the condition inside ().
• Declared using the hijo mio si keyword.
• Use the de lo contrario keyword to define what to do if the condition is not true.

//Example 3
hijo mio si (condiition) "🃏

  //Code

🃏"


//Example 2
hijo mio si (condiition) "🃏

  //Code if true

🃏" de lo contrario "🃏

  //Code if false

🃏"

You can chain If Statements

//Example 3

hijo mio si (condition_1) "🃏

  //if cond 1

🃏" de lo contrario hijo mio si (condition_2) "🃏

  //if cond 2

🃏" de lo contrario "🃏

  //else

🃏"

Printing

OsomarScript provides a print function to display output to the console, call it with ctm()

ctm("Hello world") jajaja

Functions

Functions allow you to encapsulate reusable pieces of code. They can be declared using the we keyword and can accept parameters and return values with the keyword nmms.

we square(num) "🃏
  nmms num * num jajaja //return num * num
🃏"

ctm(square(5)) jajaja // Output: 25

Example Program

// Variables
Ei miNombre es "Osomar" jajaja
Ei miNumero es 5 jajaja
Ei miVerdadero es verdad jajaja
Ei miFalso es falso jajaja
Ei miNull es sepa dios jajaja


//Printing
ctm(miNombre) jajaja

// Conditional statement
Ei x es 1 jajaja

hijo mio si (x == 1) "🃏

  ctm("Num 1") jajaja

🃏" de lo contrario hijo mio si (x==2) "🃏

  ctm("Num 2") jajaja

🃏" de lo contrario "🃏

  ctm("Num any") jajaja

🃏"


// Function
we square(num) "🃏
  nmms num * num jajaja //return num * num
🃏"

ctm(square(5)) jajaja // Output: 25


// While loop
Ei countdown es 3 jajaja
no digas mamadas mientras (countdown > 0) "🃏

  ctm(countdown)jajaja
  countdown es countdown - 1 jajaja

🃏"


no digas mamadas mientras (verdad) "🃏

  ctm("Solo se corre una vez") jajaja
  mamo jajaja //Break

🃏"
