AugustNagro/magnum

Magnum is a Scala 3 ORM that provides a repository-based pattern for type-safe database access across multiple dialects including PostgreSQL, MySQL, and ClickHouse. It features built-in codecs for complex PostgreSQL types such as JSON, XML, arrays, and geometric data, alongside support for Scala enums. The system also offers a ZIO integration layer for managing database connections and transactions within ZIO effects.

New \JsonBDbCodec\, \JsonDbCodec\, and \XmlDbCodec\ traits have been introduced to enable seamless mapping of PostgreSQL \jsonb\, \json\, and \xml\ columns to Scala types. These codecs handle the encoding and decoding of data using \PGobject\, allowing users to store and retrieve structured JSON and XML content directly through the database codec interface.

This change introduces the Magnum library, a Scala 3 ORM that provides a repository pattern for database access. It includes core abstractions such as \DbCodec\ for type-safe JDBC mapping, \Frag\ for SQL interpolation, and \Repo\/\ImmutableRepo\ for data access. The library supports multiple database dialects via specific \DbType\ implementations (Clickhouse, H2, MySQL, Oracle, Postgres) and features streaming query support via \Query.iterator\, configurable logging via \SqlLogger\, and transaction management through \DbTx\. It also adds support for composite IDs, optional UUIDs, and various date/time types.

Added TransactorZIO, a new integration layer that enables database transactions and connections within ZIO effects. This component provides ZIO-compatible methods for connecting to the database and executing transactions, including proper resource management for connection acquisition and release, SQL logging support, and customizable connection configuration via ZIO layers.

The PostgreSQL module now includes built-in codecs for handling PostgreSQL-specific data types. Users can now map arrays of common types (including UUIDs) to Scala collections like Seq, List, Vector, and Buffer, as well as map PostgreSQL geometric types such as points, lines, boxes, circles, and polygons directly to their corresponding Java objects.

Added new codec implementations in the \magnum-pg/enums\ package to enable automatic mapping between Scala Enums and database values. \PgEnumDbCodec\ allows single-value mapping for PostgreSQL-specific enum types, while \PgEnumToScalaEnumSqlArrayCodec\ and \PgStringToScalaEnumSqlArrayCodec\ provide support for multi-dimensional arrays of PostgreSQL enums and standard SQL strings (VARCHAR/text) respectively. These changes allow users to seamlessly persist and retrieve Scala Enum cases using both native Postgres enum types and standard string columns.

The \ImmutableRepo\ and \RowConverter\ traits have been removed from the core library. This eliminates the previous mechanism for converting database \ResultSet\ rows into domain objects, meaning users can no longer rely on these specific interfaces for row mapping and must adopt the current data-access patterns provided by the library.

The project documentation has been significantly expanded and restructured in the README, introducing new sections for ZIO integration, type-safe transaction management, and batch updates, while updating the installation instructions to require Scala 3.3.0 and version 1.3.0 of the library. Additionally, the .scalafmt configuration has been updated to version 3.8.4-RC3 with new formatting rules, and the .gitignore file has been extended to exclude database files and IDE-specific metadata.

Added ZIO integration tests for PostgreSQL; Added comprehensive integration tests for PostgreSQL-specific data types and codecs; Added comprehensive test suite for ClickHouse and expanded cross-database coverage.

The project has upgraded its base Scala version from 3.2.2 to 3.3.7 and updated the major version to 2.0.0-SNAPSHOT. This change includes updates to key testing and database driver dependencies, specifically upgrading MUnit to 1.1.0, the PostgreSQL driver to 42.7.4, and adding support for MySQL 9.0.0, H2 2.3.232, Oracle ojdbc11 21.9.0.0, ClickHouse 0.6.0, and SQLite 3.46.1.3 via Testcontainers. The build structure has also been refactored to explicitly define \magnum\, \magnumPg\, and \magnumZio\ subprojects with updated dependency scopes.
