circe/circe-yaml

This system is a Scala library that provides YAML serialization and deserialization capabilities for Circe JSON objects. It supports multiple YAML standards and backends, including YAML 1.1 via SnakeYAML, YAML 1.2 via snakeyaml-engine, and a Scala.js/Scala Native compatible backend using scala-yaml. The library offers configurable parsing and printing options, such as handling empty keys, controlling indentation, and managing character escaping, while enforcing code quality through standardized linting and formatting tools.

Users can now use scala-yaml as an alternative backend for parsing and printing YAML in the circe-yaml library. This change introduces new implementation files (Parser.scala, Printer.scala, and associated package objects) in the shared module that bridge circe's Json type with scala-yaml's Node structures, enabling YAML operations to run on Scala.js and Scala Native platforms. The implementation handles parsing scalars, sequences, and mappings, as well as pretty-printing JSON back to YAML, with corresponding test coverage for parsing edge cases and printing formatting.

A new \circe-yaml-v12\ module is added, providing YAML 1.2 parsing and printing capabilities backed by the \snakeyaml-engine\ library. This module introduces a new \PrinterBuilder\ that allows users to configure output formatting, including the ability to drop empty objects and arrays, control indentation with indicators, and handle non-printable characters. The module also provides a new \Parser\ implementation with configurable settings for duplicate keys, recursive keys, and comment parsing, exposing these via a dedicated \Config\ case class.

The library now supports multiple YAML backends: the original \circe-yaml\ for YAML 1.1 (using SnakeYAML), a new \circe-yaml-v12\ module for YAML 1.2 (using snakeyaml-engine), and a \circe-yaml-scalayaml\ module for Scala.js/Scala Native compatibility (using scala-yaml). The README has been completely rewritten to reflect these changes, including updated usage instructions, API examples, and build badges. Additionally, the project now includes configuration files for Scalafmt (v3.11.5), Scalafix, and Scalastyle to enforce code style and linting rules.

The circe-yaml module introduces a new PrinterBuilder that allows users to configure the YAML printer to drop empty objects and arrays via the new \dropEmptyKeys\ option. This is implemented in the new PrinterImpl class, which checks for empty collections when converting JSON objects to YAML nodes. The existing Printer class remains unchanged and does not support this feature, while the PrinterBuilder provides a fluent API to configure various printing options including the new empty-key dropping behavior.

The custom YAML parser and printer implementations that relied on the SnakeYAML library have been removed from the codebase. This eliminates the ability to parse YAML strings into Circe JSON objects and serialize JSON back to YAML using the previous SnakeYAML-backed components, effectively stripping out this specific serialization/deserialization capability from the main source directory.

The circe-yaml-common/shared module now provides the foundational Parser and Printer traits that define the core YAML serialization interface. The Parser trait exposes methods for parsing YAML streams and decoding JSON objects, including safety limits for alias cycles and code points to prevent resource exhaustion. The Printer trait defines the contract for converting JSON to YAML strings, with configuration options for flow/block styles, line breaks, and string escaping. These abstractions serve as the backend-agnostic layer for YAML processing.

Added test coverage for YAML parsing, printing, and escaping; Added test coverage for circe-yaml v12 module; Removal of ParserTests.scala.

The library has been upgraded to use circe 0.14.14, replacing the older circe-parser with circe-jawn for parsing, and updated to SnakeYAML 2.2 for YAML 1.1 support. The build now supports Scala 2.13.16 and Scala 3.3.7, and introduces new modules for YAML 1.2 support via snakeyaml-engine and for scala-yaml integration. Test dependencies have also been updated to ScalaTest 3.2.20, ScalaCheck 1.20.0, and discipline-core 1.7.0.
