doCheck

Introduction

doCheck is an open-source type checking module written in Python, released under the Mulan Permissive Software License v2 (MulanPSL-2.0). This module provides a set of reusable Checker classes for validating properties and conditions of different types of values.

Installation

pip install doCheck

Features

• Provides various logical operator overload methods such as intersection, union, complement, negation, etc., for composing complex data validation rules.
• Includes LiteralChecker (also known as EnumChecker) to check if a value is in a predefined list.
• TypeChecker is used to validate if a value belongs to a specific collection of data types.
• RangeChecker supports conditional checks within a numeric range and allows customization of interval closure.
• Additionally, CallableChecker and RegexChecker are provided to check if a value is a callable object and if a string matches a regular expression, respectively.

Usage Example

import doCheck as dc

# Create checker instances
is_integer = dc.TypeChecker(int)
is_even = dc.RangeChecker(0, float('inf'), leftClosed=True, step=2)
is_valid_name = dc.RegexChecker(r'^[A-Za-z]+\s[A-Za-z]+$')

# Apply checkers
print(is_integer.check(42))  # Output: True
print(is_even.check(10))     # Output: True
print(is_valid_name.check("John Doe"))  # Output: True
