vitorsvieira/dilate

This system is a Scala library that provides compile-time macros, specifically @newtype and @valueclass, to generate boilerplate code for type-safe wrappers and optimized value classes. It enables developers to create unboxed tagged types and value classes with zero runtime allocation by automatically expanding annotations into traits, types, and implicit conversions. The project includes comprehensive test coverage and build configurations for multiple Scala versions.

Added an examples file that showcases the newtype macro implementation, providing type-safe wrappers with zero runtime allocation for case classes. The file includes comparisons between standard case classes and those using the @valueclass and @newtype annotations, demonstrating how the macro generates newtypes for fields and handles default argument values.

The library now provides two new compile-time macros, @newtype and @valueclass, which automatically generate boilerplate code for unboxed tagged types and value classes. The @newtype macro expands to generate traits, types, and implicit classes in the companion object, while @valueclass generates value classes and implicit definitions. These macros simplify the creation of type-safe wrappers and optimized value classes by handling the code generation at compile time.

The project's build configuration was updated to set the version to 0.1.3-SNAPSHOT. The README was expanded to include a detailed overview, motivation, and usage examples for the \@valueclass\ and \@newtype\ macros. The Travis CI configuration was added to support Scala 2.11.11 and 2.12.3 on Oracle JDK 8. The LICENSE file was updated to reflect the correct copyright holder, and the .gitignore was updated to include .iml files.

(repo-wide) · medium confidence

Added two new test suites, NewTypeMacroSpec and ValueClassMacroSpec, which verify the compilation constraints and runtime behavior of the @newtype and @valueclass annotations. These tests confirm that the macros correctly restrict usage to classes, generate implicit conversions for the underlying types, and preserve access to class and companion object members after macro expansion.

src/test · high confidence

The build configuration has been updated to support Scala 2.12.3 (previously 2.12.1) and includes a new dependency on scalameta 1.8.0. Additionally, the project now integrates the SbtScalariform plugin for code formatting and enables various Scala compiler options such as -Xlint and -Ywarn-unused. The build also adds publishing and release configuration for Sonatype.
