Bhailang – A Toy Programming Language

Last Updated : 12 Apr, 2025

Coding involves a wide array of programming languages. A beginner might find the syntax intimidating. What about if there was a Hindi linguistic version of coding? After all these programming languages such as C, C++, and Python, here we have Bhailang, created by our own Indian engineers spawned out of inside jokes. Bhailang is a toy language written in Typescript. The term ‘toy language’ refers to any computer programming language that does not meet the standards for general purpose applications.

Key Terminologies

Entry & Exit point: A program must begin with a hi bhai and end with a bye bhai.
Variables: Variables are declared with bhai ye hai.
Datatype: Numbers and strings are just like any other language. Null values are indicated with nalla. Sahi and Galat represent boolean values.
Output: Any console output can be printed with bol Bhai.
Conditionals: If the condition is Sahi (True), then the agar bhai (if) block will be executed, and if the condition is galat (false), then the warna bhai (else) block will be executed.
Loops: Jab tak bhai blocks execute statements as long as a specified condition evaluates to sahi (true). Upon reaching galat, the statement within the loop stops executing, and control passes to the statement following the loop.
Control Statements: Break the loop with bas kar bhai (break) and continue within it with agla dekh (continue) bhai.
Errors: It throws a syntax error with Kya kar rha hai tu statement.

Steps to try Bhailang:

Step 1: Environment Setup

Install Visual Studio code on your local machine.

Make sure you have Node.js installed. Download it using the link below if you haven’t already.

Download Link: https://nodejs.org/en/

Install Bhailang globally by using the following command

npm i -g bhailang

Installing bhailang

In Visual Studio code go to Extensions or press Ctrl + shift + x to open extensions. Search Bhailang – syntax highlight, autocomplete extension and install it.

Installing Bhailang extension in Vs code

Step 2: Create a file named gfg.bhai in a new project directory.

Bhailang files have the extension .bhai

We will start our program with hi bhai and end it with bye bhai. In this example, we will declare a few variables and explore the use of conditions and loops in Bhailang.

Add the following code in gfg.bhai file.

// Entry point

hi bhai

// bol bhai- prints the statements in console

bol bhai “Welcome to GeeksforGeeks!”;

bol bhai “Let’s code in our Hindi Lingo using Bhailang”;

// Declaring the Variables

bhai ye hai a = 5;

bhai ye hai b = 3;

// Sahi represents a boolean value True

bhai ye hai c = sahi;

bhai ye hai d = galat;

// loop

jab tak bhai (b < 8) {

bol bhai b;

// if else construct

agar bhai (b == a){

bol bhai “b is equal to a”;

bol bhai c;

}

warna bhai

bol bhai d ;

b += 1;

}

// exit point

bye bhai
