Getting Started

Introduction to BanglaCode

BanglaCode is a Bengali-syntax programming language that makes coding accessible to Bengali speakers. Write code using familiar Bengali words in English script (Banglish).

Bengali Syntax

Use Bengali keywords like dhoro, jodi, kaj

Full-Featured

OOP, modules, error handling, HTTP servers

Easy to Learn

Intuitive syntax for Bengali speakers

What is BanglaCode?

BanglaCode is a tree-walking interpreter written in Go that allows you to write programs using Bengali keywords. The language uses Banglish (Bengali words written in English/Latin script) to make it easy to type on any keyboard while remaining familiar to Bengali speakers.

Design Philosophy

Accessibility - Lower the barrier for Bengali speakers to learn programming
Completeness - Full programming language features, not just a toy
Familiarity - Keywords match natural Bengali expressions
Simplicity - Clean, minimal syntax without unnecessary complexity

Quick Example

Here's a simple BanglaCode program that demonstrates the core syntax:

hello.bangbanglacode

1 // Variable declaration
2 dhoro naam = "Ankan";
3 dhoro boyosh = 25;
4 
5 // Print output
6 dekho("Namaskar! Amar naam", naam);
7 
8 // Conditional
9 jodi (boyosh >= 18) {
10     dekho(naam, "is an adult");
11 } nahole {
12     dekho(naam, "is a minor");
13 }
14 
15 // Loop
16 ghuriye (dhoro i = 1; i <= 5; i = i + 1) {
17     dekho("Count:", i);
18 }
19 
20 // Function
21 kaj square(n) {
22     ferao n * n;
23 }
24 
25 dekho("5 squared =", square(5));

Language Features

BanglaCode is a complete programming language with:

Feature	Description
29 Bengali Keywords	All control flow, declarations, and async/await in Bengali
95+ Built-in Functions	String, array, math, file I/O, HTTP, JSON, networking (TCP/UDP/WebSocket), and complete OS-level system access
Object-Oriented	Classes, constructors, methods, instances
Module System	Import/export with namespace support
Error Handling	Try-catch-finally with throw
HTTP Server	Build web applications

Architecture

The interpreter follows a classic pipeline architecture:

Source Code → Lexer → Tokens → Parser → AST → Evaluator → Result

Lexer - Tokenizes source code, recognizes Bengali keywords
Parser - Builds Abstract Syntax Tree using Pratt parsing
Evaluator - Tree-walking interpreter executes the AST

File Extension

BanglaCode source files use the .bang extension. For example:hello.bang, calculator.bang, server.bang.

Installation

Build and install the BanglaCode interpreter

Quick Start

Write your first BanglaCode program

1	// Variable declaration
2	dhoro naam = "Ankan";
3	dhoro boyosh = 25;
4
5	// Print output
6	dekho("Namaskar! Amar naam", naam);
7
8	// Conditional
9	jodi (boyosh >= 18) {
10	dekho(naam, "is an adult");
11	} nahole {
12	dekho(naam, "is a minor");
13	}
14
15	// Loop
16	ghuriye (dhoro i = 1; i <= 5; i = i + 1) {
17	dekho("Count:", i);
18	}
19
20	// Function
21	kaj square(n) {
22	ferao n * n;
23	}
24
25	dekho("5 squared =", square(5));
