xyncro/chiron

Chiron is a .NET library for JSON serialization and parsing, designed with a focus on robust error reporting and functional programming patterns. It provides comprehensive tools for encoding and decoding JSON data, including support for complex types, schema definitions, and variable-length strings. The system emphasizes reliability through property-based testing and a design that aggregates multiple parsing errors rather than failing on the first issue.

Added a new benchmarking project (Chiron.Benchmarks) to measure the performance of JSON serialization and parsing. The suite includes benchmarks for encoding and decoding complex and simple types using both explicit and inferred APIs, as well as parsing and formatting operations. It also compares Chiron's string escaping and parsing against Newtonsoft.Json and includes tests for variable-length strings and JSON Schema definitions.

The repository has been restructured to support .NET Core and modern build tooling. A new solution file (Chiron.sln) organizes the project into src, tests, and benchmarks, while the build process is now driven by a PowerShell script (build.ps1) and CI configurations for Travis and Appveyor. Additionally, standard repository configuration files have been added: .editorconfig for consistent code formatting, .gitattributes for line-ending normalization, and a comprehensive .gitignore. The project also includes a LICENSE.md and updated README.md with installation instructions.

(repo-wide) · high confidence

The Chiron library has been refactored to use a new internal representation for JSON data and errors. Parsing and serialization now return a \JsonResult\<'a\>\ that aggregates multiple failures rather than stopping at the first error, providing more comprehensive error messages for missing or mismatched JSON members. The \Json\ type now explicitly distinguishes between Object, Array, String, Number, Bool, and Null, and the \JsonObject\ type has been updated to support both write and read operations with custom equality. Additionally, the library introduces a \ChironErrorPolicy\ to control whether deserialization stops on the first error or continues to collect all errors, and provides better formatting options for JSON output.

src/Chiron · high confidence

Added comprehensive property-based tests for round-tripping various JSON types including strings, GUIDs, integers, floats, decimals, booleans, byte arrays, DateTimes, and custom records/unions. Also added functional tests for JSON parsing, formatting, and lens-based access, ensuring serialization and deserialization work correctly across different cultures.

tests · high confidence

The project has been updated to target .NET Standard 2.0 (alongside .NET Framework 4.5.2), enabling broader compatibility. Dependencies have been updated, including FParsec to 1.0.3 and Aether to 8.2.0. The test suite has been converted to use XUnit and FsCheck, replacing the previous testing framework.
