Installation

# Using pip
pip install pysha-sdk

# Using uv (recommended)
uv pip install pysha-sdk

# With optional dependencies
pip install pysha-sdk[inflect,phonenumbers,email,bson]

Quick Start

String Utilities

from pysha_sdk import (
    to_camel_case,
    to_snake_case,
    extract_digits,
    is_valid_email,
    normalize,
    slugify,
)

# Case conversion
to_camel_case("hello_world")  # "helloWorld"
to_snake_case("HelloWorld")   # "hello_world"

# String manipulation
extract_digits("abc123def")   # "123"
is_valid_email("[e-mail]")  # (True, None)

# Text normalization
normalize("<p>Hello **world**!</p>")  # "Hello world!"

# URL-friendly slugs
slugify("Hello World!")  # "hello-world"

Crypto Utilities

from pysha_sdk import (
    hash_password,
    match_password,
    uuidv7,
    calculate_md5_hash,
    generate_random_token,
)

# Password hashing
hashed = hash_password("my_password")
match_password("my_password", hashed)  # True

# UUID generation
uuid = uuidv7()  # UUIDv7 with timestamp

# Hashing
md5_hash = calculate_md5_hash("content")  # "5d41402abc4b2a76b9719d911017c592"

# Random tokens
token = generate_random_token(32, "hex")  # 32-character hex token

Object Utilities

from pysha_sdk import (
    recursive_sort_keys,
    ChangeKeysCase,
    model_dump,
)
from pydantic import BaseModel

# Recursive key sorting
data = {"z": 1, "a": {"c": 2, "b": 1}}
sorted_data = recursive_sort_keys(data)
# {"a": {"b": 1, "c": 2}, "z": 1}

# Case conversion for dictionaries
ChangeKeysCase.to_camel_case({"first_name": "John"})
# {"firstName": "John"}

# Pydantic model dumping
class User(BaseModel):
    name: str
    age: int

user = User(name="John", age=30)
model_dump(user)  # {"name": "John", "age": 30}

DictMixin

from pysha_sdk.utils.mixins.dict_mixin import DictMixin

class MyModel(DictMixin):
    def __init__(self, **kwargs):
        for key, value in kwargs.items():
            setattr(self, key, value)

obj = MyModel(name="John", age=30)

# Dict-like access
obj["name"]  # "John"
obj["nested.deep.value"]  # Path-based access with glom

# Dict methods
list(obj.keys())  # ["name", "age"]
obj.get("missing", "default")  # "default"

Modules

String Utilities (pysha_sdk.utils.strings)

Comprehensive string manipulation functions:

• Case Conversion: to_camel_case, to_snake_case, to_kebab_case, to_pascale_case, to_constant_case, to_title_case
• Encoding/Decoding: to_hex, from_hex, to_base64, from_base64, to_ascii
• Validation: is_valid_email, is_valid_phone_number, is_valid_israeli_id, is_cron_expression, is_hex, is_ascii, is_hebrew
• Text Processing: normalize, slugify, deburr, words, compounder, extract_digits
• URL Utilities: to_url, flatten_url_params, delimited_path_join
• Pluralization: to_plural, to_singular (requires inflect)

Crypto Utilities (pysha_sdk.utils.crypto)

Cryptographic and security functions:

• Password Management: hash_password, encrypt_password, match_password
• Hashing: calculate_md5_hash
• UUID Generation: uuidv7, to_stable_uuid, uuidv7_to_datetime
• Random Generation: generate_random_id, generate_random_token, generate_unique_secure_token

Object Utilities (pysha_sdk.utils.objects)

Object and data structure manipulation:

• Pydantic Integration: model_dump, dict_or_pydantic_model_to_dict
• Key Operations: recursive_sort_keys, ChangeKeysCase (camel, snake, kebab, Pascal, constant, dot case)
• Type Utilities: is_iterable_except_str_like, find_subclasses

DictMixin (pysha_sdk.utils.mixins.dict_mixin)

A mixin class that provides dict-like interface to objects:

• Dict-like access with obj[key]
• Path-based access with glom: obj["nested.deep.value"]
• All standard dict methods: keys(), values(), items(), get(), etc.
• Works seamlessly with Pydantic models

Performance

This package uses Cython to optimize performance-critical operations. When Cython extensions are available, functions automatically use optimized implementations. If Cython isn't available, the package falls back to pure Python implementations.

Optimized Functions:

• String operations: extract_digits, is_ascii, is_hex, is_hebrew, to_hex, from_hex, to_base64, from_base64, to_ascii
• Crypto operations: calculate_md5_hash, encrypt_password, match_password, to_stable_uuid, uuidv7, uuidv7_to_datetime
• Object operations: recursive_sort_keys, change_keys_case, is_iterable_except_str_like
• DictMixin operations: All dict-like operations

Requirements

• Python 3.13+
• Optional dependencies:
  • inflect - For pluralization features
  • phonenumbers - For phone number validation/formatting
  • email-validator - For email validation
  • pymongo - For ObjectId conversion (bson)
