scala-hamsters/hamsters

Hamsters is a Scala 3 library providing core functional programming utilities, including typeclasses like Functor and Monad, along with tools for validation, retry logic, and monad transformers. It supports cross-compilation for JVM and Scala.js, offering features such as Cartesian operations, memoization, and error accumulation. The system includes a REPL script for experimentation and comprehensive test coverage to ensure the correctness of its algebraic structures and asynchronous helpers.

A new shell script (scripts/try-hamsters.sh) has been added to provide an interactive Read-Eval-Print Loop (REPL) environment for the Hamsters library. The script automatically installs the Coursier launcher if missing and launches Ammonite with the Hamsters library (version 3.0.0) and its key modules (EmptyOptionValues, FutureOps, Validation, Retry) pre-imported, allowing users to quickly experiment with the library's features.

A new \Retry\ utility has been added to the JVM module, providing a \withWait\ method that allows users to retry asynchronous operations with a specified number of maximum tries and a fixed delay between attempts. This feature enables robust error handling for transient failures by automatically re-executing a function upon failure, with a configurable callback for error reporting.

This update introduces a comprehensive set of functional programming abstractions and utilities to the library. It adds typeclasses including Functor, Monad, Semigroup, and Monoid (with instances for common types like Int, Long, String, List, and Option), along with a Show typeclass for value formatting. New capabilities include a Validation module for accumulating errors across up to 22 inputs, Cartesian operations with mapN support for tuples up to arity 22, and Monad transformers (OptionT, TryT, EitherT) with specific Future wrappers. Additional features include Lens composition, Memoization (thread-safe and unsafe), NonEmptyList, Enumerables, Retry logic, FutureOps for squashing nested futures, and an EmptyOptionValues extension for handling empty options with Monoids.

The library has removed the \Implicits\ object, which previously provided \map\ and \flatMap\ extensions for \Either\, as well as the \Validation\ class and its companion object that handled lists of \Either\ results. These components are no longer available, meaning users can no longer use the previous implicit syntax for chaining \Either\ operations or the specific \Validation\ utility for aggregating successes and failures from multiple \Either\ values.

src/main · high confidence

Added comprehensive test coverage for core library components; Added tests for JVM retry logic; Removed obsolete test suites for Implicits, MonadTransformers, and Validation.

The project has upgraded its primary language version from Scala 2.11 to Scala 3.3.8 and restructured the build to support cross-compilation for both JVM and Scala.js platforms. This change updates test dependencies to newer versions (ScalaTest 3.2.19, ScalaMock 6.0.0, ScalaCheck 1.18.1) and replaces the manual versioning and publishing setup with sbt-dynver for automatic version derivation from git tags and sbt-ci-release for publishing to the Sonatype Central Portal.
