ReactivePlatform/Pragmatic-Scala

This repository serves as a companion codebase for the 'Pragmatic Scala' book, providing runnable examples and test cases for various Scala language concepts. It covers topics such as functional programming, pattern matching, actors, recursion, and type safety, alongside corresponding Java examples for comparison. The project is structured by chapter to demonstrate specific features, errors, and best practices, supported by a Scala build environment with Akka and testing frameworks.

This update introduces several new Scala source files that provide runnable examples for the book's chapters. Chapter 1 adds \FastTopStock.scala\ (using parallel collections) and \TopStock.scala\ (sequential) to demonstrate fetching and comparing year-end stock prices. Chapter 9 introduces \ThingsAcceptor.scala\ for basic type matching and \TradeStock.scala\ for advanced pattern matching on trade transactions. Chapter 13 adds \HollywoodActor4.scala\ and \UseActor.scala\ to demonstrate Akka actor message passing and counting. Chapter 15 includes \StockPriceFinder.scala\ for fetching latest stock prices and parsing XML configurations.

This update adds a comprehensive set of runnable code samples and their corresponding expected outputs for chapters 1, 10, 11, and 12 of the Pragmatic Scala book. Chapter 1 includes examples demonstrating imperative versus functional approaches to finding maximum values and doubling lists, along with a stock data resource file. Chapter 10 introduces exception handling patterns, including catch-all blocks, exception ordering, and thread sleeping. Chapter 11 covers recursion, tail-call optimization (TCO) for factorials, trampolining for deep recursion, and bytecode inspection of recursive methods. Chapter 12 explores lazy evaluation, including lazy vals, lazy collections, streams for prime generation, and parallel processing for weather data retrieval. Each code sample is accompanied by its expected output, ensuring that readers can verify the behavior of the examples.

This change introduces the foundational configuration files for a Scala project, including \.scalafmt.conf\ (version 3.5.8) and \.scalafix.conf\ to define code formatting and static analysis rules, a \.travis.yml\ file to set up continuous integration with Scala 2.12.8 and OpenJDK 8, and an updated \.gitignore\ to exclude build artifacts and IDE-specific files. It also adds a \README.md\ documenting the project structure and usage, and a \stocks2.xml\ data file.

Added Chapter 3 Scala code examples; Added Java test examples for chapters 5, 10, and 14; Added test cases for Scala type mismatch errors in Chapter 4; Added test cases for Scala type system errors in Chapter 5; Added test files for chapters 1, 7, and 14; Added test for ThingsAcceptor2 type mismatch; Added test for chapter 6 dependency injection example; Added test for non-tail-recursive factorial implementation.

The build configuration establishes the project using Scala 2.13.16 and targets JVM 1.8. It integrates Akka 2.6.20 for actor-based concurrency, ScalaTest 3.0.8 and JUnit 4.12 for testing, and Mockito 4.5.0 for mocking. Additional dependencies include Scala XML 2.3.0 and Scala Parallel Collections 1.2.0. The build also enables documentation generation via Paradox with a Material theme and configures Git publishing via GhpagesPlugin.

ReactivePlatform/Pragmatic-Scala was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point a surveyor at a repository you know and see whether you agree with it.
