Groovy Common Extensions is a library that enhances the Groovy programming language with a set of practical utility methods via Groovy's extension system. It provides developers with convenient, idiomatic additions to standard classes, streamlining everyday coding tasks and reducing boilerplate. ## Key Features - **Implicit Conversions** — Overload `asType` to define custom type conversions between classes. - **Clamp Values** — Restrict `Comparable` values (numbers, strings, ranges) within specified bounds. - **Multi-criteria Sorting** — Sort collections using multiple closure criteria in a single call. - **Safe List Operations** — Use `take` with negative indices to safely retrieve elements from the end of a list. - **Resource Management** — Automatically close resources with `withClosable` after closure execution. - **Method Chain Debugging** — Insert `tap` into chains to inspect intermediate values without breaking the flow. - **File Compression** — Zip and unzip files or directories directly from `File` objects. - **XML/JSON/Config Parsing** — Convert strings to XML, JSON, or ConfigObject structures with `toXml`, `toJson`, and `toConfig`. - **Random Selection** — Pick random elements from lists or iterators with configurable duplication and randomness. - **Statistical Averages** — Compute mean, median, variance, and standard deviation for collections of numbers. ## Philosophy The project follows a pragmatic, utility-first approach, extending Groovy's expressive syntax with methods that feel native to the language, promoting cleaner and more concise code.
