indic-uid 0.2.0

A simple library for generating short, unique identifiers using characters from various Indian language scripts.

Indic UID

Generate short, unique identifiers using characters from Indian language scripts (Devanagari, Gujarati, Kannada, Tamil, Telugu, Bengali) and English.

Perfect for referral codes, short URLs, or any system requiring unique identifiers with an Indian language touch!

📦 Installation

pip install indic-uid

Note

The package is installed as indic-uid, but imported in Python as indic_uid

🚀 Quick Start

from indic_uid import generate_id

# Generate a random 6-character ID
id = generate_id()
print(id)  # Example: 'कஆಗઘతঅ'

# Generate with specific length
id = generate_id(length=8)
print(id)  # Example: 'अкஆগઘతaక'

# Generate from specific script
id = generate_id(scripts=['devanagari'])
print(id)  # Example: 'घअकआइश'

# Generate pronounceable IDs (alternates vowels and consonants)
id = generate_id(pronounceable=True, scripts=['devanagari'])
print(id)  # Example: 'कअखइगउ'

# Generate a numeric OTP in Devanagari
otp = generate_id(length=6, scripts=['devanagari'], numbers_only=True)
print(otp)  # Example: '३७५२१९'

📖 Usage Examples

Basic ID Generation

from indic_uid import generate_id, generate_batch

# Default: 6 characters, all scripts
id = generate_id()

# Custom length
short_id = generate_id(length=4)
long_id = generate_id(length=10)

# Generate multiple IDs at once
ids = generate_batch(count=10, length=5)
for id in ids:
    print(id)

Script Selection

# Single script
devanagari_id = generate_id(scripts=['devanagari'])
tamil_id = generate_id(scripts=['tamil'])

# Multiple scripts
mixed_id = generate_id(scripts=['devanagari', 'tamil', 'gujarati'])

# Available scripts
from indic_uid import get_available_scripts
print(get_available_scripts())
# Output: ['devanagari', 'gujarati', 'kannada', 'tamil', 'telugu', 'bengali', 'english']

Pronounceable IDs

Generate IDs that alternate between consonants and vowels for easier pronunciation:

# Pronounceable ID (easier to speak)
id = generate_id(pronounceable=True, scripts=['devanagari'])
print(id)  # Example: 'कअखइगउ' (ka-khi-gu)

# Works with any script
id = generate_id(pronounceable=True, scripts=['tamil'])
print(id)  # Example: 'கஅசஇடஉ'

Numeric IDs & OTPs

Generate IDs that include or consist entirely of script-native number characters:

# Include numbers in the character pool
id = generate_id(length=8, scripts=['devanagari'], include_numbers=True)
print(id)  # Example: 'क३ठ७अ२गइ' (mix of letters and digits)

# Generate digits-only OTPs
otp = generate_id(length=6, scripts=['devanagari'], numbers_only=True)
print(otp)  # Example: '३७५२१९'

# Tamil numeric OTP
otp = generate_id(length=4, scripts=['tamil'], numbers_only=True)
print(otp)  # Example: '௩௭௫௨'

# Multi-script numeric OTP
otp = generate_id(length=6, scripts=['devanagari', 'bengali'], numbers_only=True)
print(otp)  # Example: '३৭५২১९'

# Batch generate OTPs
otps = generate_batch(count=10, length=6, scripts=['devanagari'], numbers_only=True)

Validation

from indic_uid import is_valid_id, get_script_of_char

# Validate an ID
id = generate_id()
print(is_valid_id(id))  # True
print(is_valid_id('abc123'))  # False

# Validate with specific script
id = generate_id(scripts=['kannada'])
print(is_valid_id(id, scripts=['kannada']))  # True
print(is_valid_id(id, scripts=['tamil']))    # False

# Validate length
print(is_valid_id(id, length=6))  # True if ID is 6 chars

# Detect script of a character
char = 'क'
print(get_script_of_char(char))  # 'devanagari'

Collision Probability Analysis

from indic_uid import calculate_collision_probability, estimate_safe_id_count

# Calculate collision probability for your use case
prob = calculate_collision_probability(
    num_ids=10000,      # Expected number of IDs
    length=6,           # ID length
    num_scripts=6       # Number of scripts used
)
print(f"Collision probability: {prob:.2e}")
# Output: Collision probability: 5.45e-10 (extremely low!)

# Estimate safe number of IDs
safe_count = estimate_safe_id_count(
    length=6,
    num_scripts=6,
    max_collision_prob=0.000001  # 1 in a million
)
print(f"Safe ID count: {safe_count:,}")
# Output: Safe ID count: 13,856,406

🎯 Use Cases

Referral System

from indic_uid import generate_id

def create_referral_code(user_id):
    """Generate a unique referral code for a user."""
    referral_code = generate_id(length=6, scripts=['devanagari'])
    # Store mapping: referral_code -> user_id in database
    return referral_code

# Usage
code = create_referral_code(user_id=12345)
print(f"Your referral code: {code}")
# Share: https://yourapp.com/ref/{code}

Short URLs

from indic_uid import generate_id

def create_short_url(long_url):
    """Create a short URL identifier."""
    short_id = generate_id(length=5, scripts=['devanagari', 'gujarati'])
    # Store mapping: short_id -> long_url
    return f"https://short.link/{short_id}"

url = create_short_url("https://example.com/very/long/url/path")
print(url)  # https://short.link/कખગઘચ

Coupon Codes

from indic_uid import generate_id

def create_coupon_code(campaign_name):
    """Generate pronounceable coupon codes."""
    code = generate_id(
        length=6,
        pronounceable=True,
        scripts=['devanagari']
    )
    return code.upper()  # Note: Indian scripts don't have uppercase

coupon = create_coupon_code("diwali_sale")
print(f"Coupon: {coupon}")

📊 Collision Probability

With default settings (6 characters, all 7 scripts):

Number of IDs	Collision Probability	Odds
1,000	5.45 × 10⁻¹²	1 in 183 billion
10,000	5.45 × 10⁻¹⁰	1 in 1.8 billion
100,000	5.45 × 10⁻⁸	1 in 18 million
1,000,000	5.45 × 10⁻⁶	1 in 183,000

Conclusion: Extremely safe for most applications. Even with 1 million IDs, collision probability is less than 0.0005%.
