1loc is a JavaScript utility library and multifaceted toolkit providing a collection of single-line functions for common mathematical, string, date, and geometric operations. It functions as a set of functional programming helpers and data validation predicates designed to perform atomic transformations and validations. The project includes a geometry math library for calculating distances, angles, and spatial overlaps between points and rectangles, alongside a text manipulation library for casting, capitalizing, and analyzing string content. The toolkit covers broader capability areas inclu

Inputmask is a JavaScript library that serves as a client-side input formatter and form input validator. It constrains text input fields to specific formats, such as phone numbers and dates, to ensure data consistency. The project provides guided text entry and user input validation to prevent formatting errors. It standardizes how structured information is entered in web browsers to support more reliable server-side processing. The library manages data validation and formatting by enforcing predefined patterns on user entry. It handles real-time input interception, cursor-position tracking,

This is a regular expression library designed for the validation and identification of mobile phone numbers from mainland China. It provides the structural rules and digit constraints necessary to verify that phone numbers follow the correct regional format. The library includes specific patterns to determine the telecommunications provider based on regional prefixes. It also features filters to distinguish between standard voice numbers and IoT or data-only plans. The project covers broad data validation capabilities, including input format verification and carrier identification.

CLI11 is a header-only C++ library for parsing command line arguments and managing configuration files. It maps shell input to typed variables and supports the creation of complex command hierarchies. The library is distinguished by its support for nested subcommands with infinite depth and prefix matching. It integrates configuration management by allowing application settings to be loaded from TOML or INI files, with the ability to fall back to environment variables. The project provides a comprehensive set of tools for argument parsing, including flags and positional arguments, alongside
