rmunn/Ficus

Ficus is a .NET library providing fast, immutable data structures, specifically featuring a Relaxed Radix Balanced (RRB) Vector with both persistent and transient APIs. It supports multiple .NET versions and includes comprehensive property-based testing to ensure correctness. The project also maintains a documentation site with modern styling and dark mode support.

Ficus introduces a new Relaxed Radix Balanced (RRB) Vector implementation, providing a persistent, immutable data structure with O(1) push/pop and effectively O(1) concatenation and splitting. The library exposes a public API for creating, modifying, and querying vectors, along with a transient mode that allows efficient bulk updates before materializing a new persistent instance. The implementation includes internal node types (full, relaxed, leaf) and array extension utilities to support these operations.

The build infrastructure has been updated to target .NET 8, replacing the previous .NET 6 target. This change includes new build scripts (Changelog.fs, FsDocs.fs, build.fs) and a corresponding packages.lock.json that resolves dependencies for the net8.0 framework, ensuring the build tooling runs on the newer runtime.

The documentation site has been updated to use a new HTML template based on Bootstrap 5, replacing the previous styling. This change introduces a user-facing dark mode toggle in the navigation bar, allowing readers to switch between light, dark, and auto themes. The visual presentation of the documentation is also refreshed with new CSS files defining specific color palettes for code highlighting, typography, and layout adjustments.

The legacy Paket MSBuild integration files (.paket/Paket.Restore.targets, .paket/paket.exe.config, and .paket/paket.targets) have been removed from the project. This change eliminates the custom MSBuild targets that previously handled package restoration and NuSpec fixing via the Paket tool, indicating a migration away from this specific Paket-based build integration approach.

This change introduces several foundational updates to the project's repository structure and build process. It adds configuration files for Git (\.fantomasignore\, \.git-blame-ignore-revs\, \.gitattributes\) to standardize line endings, manage formatting commits, and handle binary assets via Git LFS. The build system is updated with new MSBuild targets (\Directory.Build.props\ and \Directory.Build.targets\) that enforce Fantomas code formatting and manage dotnet local tools. Additionally, the solution structure is defined in \Ficus.slnx\, and the project targets the .NET SDK version 10.0.100 as specified in \global.json\. The changelog is also initialized to document future releases.

Comprehensive FsCheck property and stateful command tests for RRBVector; Initial comprehensive test suite for RRBVector implementation.

The project has upgraded its build and runtime targets to .NET 10, with the main library now supporting netstandard2.0, net8.0, net9.0, and net10.0, while the test suite targets net10.0 exclusively. This change replaces the legacy Paket dependency manager with MSBuild Central Package Management (via Directory.Packages.props), updating core dependencies such as FSharp.Core to 10.0.102, Expecto to 10.2.2, and FAKE to 6.1.4. Additionally, the build infrastructure was updated to target net8.0, and the library's description was refined to 'Fast, immutable collections based on tree structures'.
