magnolify

A collection of Magnolia add-ons for common type class derivation, data type conversion, etc.; a simpler and faster successor to shapeless-datatype.

Modules

This library includes the following modules.

• magnolify-cats - type class derivation for Cats, specifically

  • Eq[T]
  • Hash[T]
  • Semigroup[T], CommutativeSemigroup[T], Band[T]
  • Monoid[T], CommutativeMonoid[T]
  • Group[T], CommutativeGroup[T]

• magnolify-scalacheck - type class derivation for ScalaCheck

  • Arbitrary[T]
  • Cogen[T]

• magnolify-guava - type class derivation for Guava

  • Funnel[T]

• magnolify-parquet - support for Parquet columnar storage format.

• magnolify-refined - support for simple refinement types from Refined.

• magnolify-avro - conversion between Scala types and Apache Avro GenericRecord

• magnolify-bigquery - conversion between Scala types and Google Cloud BigQuery TableRow

• magnolify-bigtable - conversion between Scala types and Google Cloud Bigtable to Mutation, from Row

• magnolify-datastore - conversion between Scala types and Google Cloud Datastore Entity

• magnolify-protobuf - conversion between Scala types and Google Protocol Buffer Message

• magnolify-tensorflow - conversion between Scala types and TensorFlow Example

Usage

See derivation.md for type class derivation for Cats, Scalacheck, and Guava.

See avro.md bigquery.md bigtable.md datastore.md protobuf.md tensorflow.md for data type conversions for these libraries. See parquet.md for Parquet IO support. Also see enums.md for enum types and refined.md for refinement types support. Finally see mapping.md for a mapping table of Scala types supported by conversion and IO modules.
