Towards a safe, sane I O library in Scala
summary
A new Scala library called better-files wraps Java NIO with no external dependencies and implements safe defaults, automatic resource management (self-closing iterators and autoclose implicits), and a single File class with rich ops for copy/move/zip/permissions and pattern-matched file types. Benchmarks show the scanner is 8x faster than java.util.Scanner. It adds both a thread-backed file watcher and an Akka-based reactive watcher, ships with tests and CI, sits at about 3,000 lines of code, and is used in production.
