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-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-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-datastore - conversion between Scala types and Google Cloud Datastore Entity
• magnolify-guava - type class derivation for Guava
  • Funnel[T]
• magnolify-neo4j - conversion between Scala types and Value
• magnolify-parquet - support for Parquet columnar storage format.
• magnolify-protobuf - conversion between Scala types and Google Protocol Buffer Message
• magnolify-refined - support for simple refinement types from Refined.
• magnolify-scalacheck - type class derivation for ScalaCheck
  • Arbitrary[T]
  • Cogen[T]
• 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.

How to Release

Magnolify automates releases using sbt-ci-release with Github Actions. Simply push a new tag:

git tag -a v0.1.0 -m "v0.1.0"
git push origin v0.1.0

Note that the tag version MUST start with v to be picked up as the release version.
