युक्ति (Yukti) Programming Language

Version: 1.0
Status: Specification Phase
License: Proprietary - All Rights Reserved

Overview

Yukti (युक्ति) is a modern, statically-typed, compiled programming language that draws inspiration from Indian philosophical traditions while incorporating contemporary programming paradigms. The name 'Yukti' means "strategy," "method," or "logical reasoning" in Sanskrit.

Philosophy

Yukti's design is rooted in Indian philosophical concepts:

• Dharma (धर्म) - Responsibility through ownership and RAII
• Karma (कर्म) - Actions and consequences in concurrency
• Satya (सत्य) - Truth through strong typing and correctness
• Samyama (संयम) - Discipline through immutability by default

Key Features

✨ Static Type System with type inference
🔒 Memory Safety through ownership and borrowing
⚡ Zero-Cost Abstractions for performance
🎭 Pattern Matching and algebraic data types
🔄 Karma-based Concurrency (actor model)
🛠️ Compile-time Metaprogramming (Mantra system)
🔗 C/C++ Interoperability through FFI

Quick Start

Hello World

prakriya main() -> Shunya {
    likho("Namaste, Vishwa!");
}

Variables

// Immutable by default
sthir x: Ank32 = 42;

// Mutable when needed
parivartan count: Ank32 = 0;
count = count + 1;

Functions

prakriya jod(a: Ank32, b: Ank32) -> Ank32 {
    vapasi a + b;
}

// Pure functions
pavitra prakriya square(n: Ank32) -> Ank32 {
    vapasi n * n;
}

Data Structures

sangrah Vyakti {
    naam: Shabd,
    aayu: Ank32,
}

prakar Parinam<T, E> {
    Safal(T),
    Asafal(E),
}

Pattern Matching

milaan number {
    0 => "shunya",
    1 => "ek",
    2..=10 => "kuch",
    _ => "bahut"
}

Concurrency (Karma)

karma prakriya fetch_data() -> Shabd {
    // Async operation
    vapasi "Data fetched";
}

prakriya main() -> Shunya {
    sthir result = pratiksha fetch_data();
    likho(result);
}

Type System

Primitive Types

• Shunya - Unit/void type
• Satya - Boolean (satya/asatya)
• Ank8, Ank16, Ank32, Ank64 - Signed integers
• Uank8, Uank16, Uank32, Uank64 - Unsigned integers
• Dashamlav32, Dashamlav64 - Floating point
• Akshar - Unicode character
• Shabd - UTF-8 string

Advanced Types

• Sambhavya - Optional (Some/Kuch or None/Nahin)
• Parinam<T, E> - Result (Success/Safal or Failure/Asafal)
• Suchi - Dynamic array
• Muth<K, V> - Hash map

Memory Management

Ownership (Swamitva)

sthir s1 = "hello".roop();
sthir s2 = s1;  // s1 is moved to s2
// s1 is no longer valid

Borrowing (Udhar)

// Immutable borrow
prakriya lambai(s: &Shabd) -> Ank32 {
    vapasi s.lambai();
}

// Mutable borrow
prakriya jodo(s: &parivartan Shabd, text: Shabd) {
    s.jodo(text);
}

Standard Library (Shastra)

• shastra::io - Input/output operations
• shastra::sangrah - Collections (Suchi, Muth, Samuchay)
• shastra::sankhya - Mathematical operations
• shastra::samay - Time and duration
• shastra::file - File system operations
• shastra::jaal - Networking
• shastra::karma - Concurrency primitives

Example Programs

See the examples/ directory for complete examples:

• hello.yukti - Hello World
• structures.yukti - Data structures and methods
• concurrency.yukti - Async/await and message passing
• error_handling.yukti - Result types and error propagation

Build System (Nirman)

Projects use the Nirman (निर्माण) build system:

# Nirman.toml
[package]
naam = "my-project"
version = "0.1.0"
authors = ["Your Name"]

[dependencies]
shastra = "1.0"

Build commands:

nirman build      # Compile project
nirman run        # Compile and run
nirman test       # Run tests
nirman clean      # Clean build artifacts

Compiler (yuktic)

Compilation pipeline:

1. Lexical Analysis
2. Parsing (AST generation)
3. Semantic Analysis (type & borrow checking)
4. MIR Generation
5. Optimization
6. LLVM IR Generation
7. Linking

Philosophy Quotes

"युक्तियुक्तं वचो ग्राह्यं बालादपि शुकादपि"
"Accept the logical, even from a child or a parrot"
— Sanskrit Subhashita

This principle guides Yukti's design: embrace good ideas regardless of their source, and let logic and reason prevail.
