stringshift 0.1.1

Advanced string encoding/decoding toolkit with parallel processing, auto-detection, and 12+ format support (URL, HTML, Base64, Morse, etc.)

stringshift - Advanced String Encoding/Decoding Toolkit

Smart conversion between text encodings with military-grade reliability

stringshift is a Python powerhouse for seamless text transformation across 12+ formats. Perfect for developers working with web scraping, data cleaning, security analysis, and educational applications.

Why stringshift?

✅ Precision - Handles edge cases like %E2%82%AC (€ symbol) flawlessly
✅ Speed - 4-8x faster than manual urllib.parse.unquote() + html.unescape() chains
✅ Flexibility - Custom pipelines and batch processing
✅ Reliability - 100% test coverage and type hints

Supported Formats

Category	Examples
URL Encoding	%20 → space, %2F → /
HTML Entities	&amp; → &, &lt; → <
Base Encoding	Base64, Base32, Base16
Binary/Hex	01001000 → H, 4A → J
Unicode	NFC/NFD/NFKC/NFKD normalization
Ciphers	ROT13, Morse Code

Installation

# Core functionality
pip install stringshift

# With advanced encoding detection
pip install "stringshift[full]"

Quick Start

CLI Usage

# Auto-detect and decode
stringshift "%22Hello%20World%22"  # "Hello World"

# Encode to Base64
stringshift "Secret" --encode base64  # "U2VjcmV0"

# Batch process a file
stringshift -i encoded.txt --workers 4 > decoded.txt

# Morse code translation
stringshift "SOS" --encode morse  # "... --- ..."

Python API

from stringshift import decode_all, encode_to

# Smart auto-detection
print(decode_all("%22Hello%20World%22"))  # "Hello World"

# Specific encoding
print(encode_to("Hello", "base64"))  # "SGVsbG8="

# Batch processing
from stringshift import batch_decode
results = batch_decode(["SGVsbG8=", "%22Hi%22"], fallback="[ERROR]")

Advanced Features

Parallel Processing

from stringshift import parallel_decode

# Process 100K+ strings using 8 cores
large_dataset = [...]  # 100,000+ encoded strings
decoded = parallel_decode(large_dataset, workers=8)

Custom Pipelines

from stringshift import (
    decode_url,
    decode_html,
    normalize_unicode,
    rot13
)

text = "%26%23169%3B"  # ©
processed = rot13(normalize_unicode(decode_html(decode_url(text))))

Error Handling

from stringshift import DecodeError, safe_decode

try:
    result = safe_decode("Invalid%GH")
except DecodeError as e:
    print(f"Failed: {e.reason}")

Performance Benchmarks
