fsprojects/Chessie

Chessie is a functional programming library for F\# that provides a Result type and computation expressions for robust error handling and validation. It supports chaining operations and accumulating failure messages, enabling developers to manage side effects and errors in a pure functional style. The library is designed for cross-language interoperability, offering comprehensive test coverage for C\# and Visual Basic consumers.

The build system now supports .NET Core by adding a new C\# test project (Chessie.CSharp.Test) to the solution, configuring NuGet package sources for ASP.NET Core and NuGet, and updating the FAKE build script to build and test .NET Core projects using the dotnet CLI. Additionally, the solution file is updated to include the new C\# test project and its build configurations.

(repo-wide) · high confidence

The library now provides a new error-handling module (ErrorHandling.fs) that introduces a Result type representing either a success or a failure with accumulated messages. This includes a Trial computation expression builder for chaining operations, combinators like bind, apply, and collect, and helper functions for mapping, flattening, and pattern matching on results. The change also updates the package metadata and version to 0.6.0, and adds a dependency on FSharp.Core.

src/Chessie · high confidence

Added C\# test suite for Chessie error handling; Added Visual Basic test suite for Chessie error handling; Added comprehensive test suite for the 'trial' computation expression and validation helpers.

The build infrastructure was updated, including bumping the C\# compiler warning level to 5 and adding a dependency on the FSharp.Core NuGet package. Additionally, new test projects were added for C\# (Chessie.CSharp.Test) and VB.NET (Chessie.VisualBasic.Tests), which include tests for validation and extension methods.
