Maintenance scripts for the ReactiveUI repository.

Regenerates the PublicAPI baseline files consumed by Microsoft.CodeAnalysis.PublicApiAnalyzers (RS0016, RS0017, RS0037).

Each shipped library tracks its public surface per target framework in:

src/<Project>/PublicAPI/<tfm>/PublicAPI.Shipped.txt
src/<Project>/PublicAPI/<tfm>/PublicAPI.Unshipped.txt

When you add, remove, or change public API, those files must be updated or the build fails with RS0016 (symbol not in baseline) / RS0017 (baseline entry not found) / RS0037 (missing #nullable enable). These scripts do that for you.

Only projects with the MSBuild property TrackPublicApi=true are processed. The tests/ and benchmarks/ trees opt out centrally in src/Directory.Build.props, so they are never touched.

Linux / macOS:

tools/generate-publicapi.sh                 # all tracked libraries, all buildable TFMs
tools/generate-publicapi.sh Async           # only projects whose path contains 'Async'
tools/generate-publicapi.sh ReactiveUI.Wpf

Windows (PowerShell):

./tools/generate-publicapi.ps1                  # all tracked libraries
./tools/generate-publicapi.ps1 -Filter Async    # path filter

The optional argument is a case-sensitive substring matched against each project's path, so you can scope a run to a single library while iterating.

1. Resets both PublicAPI/<tfm>/PublicAPI.Shipped.txt and PublicAPI.Unshipped.txt to just #nullable enable, so the analyzer reports the entire current surface.
2. Runs dotnet format analyzers <proj> -f <tfm> --diagnostics RS0016 RS0017 RS0037 --severity info, which fills PublicAPI.Unshipped.txt with the current public API.
3. Folds that surface into PublicAPI.Shipped.txt (ordinally sorted, deduped) and resets PublicAPI.Unshipped.txt back to the bare header. This repo keeps the full surface in Shipped with Unshipped empty, so a later API change shows up as new Unshipped lines.

• Run the script on the OS that can build the frameworks you need:
  • Windows builds the .NET Framework and Windows-desktop (WPF / WinForms / WinUI) TFMs natively, plus Android and — with the matching workloads — the Apple TFMs. Use generate-publicapi.ps1. This repo's Windows/Apple legs are generated on the dockur Windows guest (~/dockur-windows); the repo is shared in-guest as \\host.lan\Data\rxui\reactiveui.
  • Linux builds net8.0+, Android, and the Windows-desktop TFMs cross-platform (the script sets EnableWindowsTargeting=true). It cannot produce Apple (-ios / -maccatalyst / -tvos / -macos) baselines.
  • macOS additionally builds the Apple TFMs.
• A target framework whose workload or SDK is missing is skipped with a warning (its seed files are left in place); the rest of the run continues. The script's exit code is non-zero if any TFM failed, so CI can detect an incomplete run.
• The scripts set MinVerVersionOverride (default 255.255.255-dev) so versioning does not depend on git history; override it by exporting/setting the variable first.

• After changing any public (or protected on a public type) API.
• After adding a new target framework to a tracked library.
• After bumping an analyzer package that changes how the public surface is rendered.

Review the resulting PublicAPI.Unshipped.txt diff before committing — it is the human-auditable record of your public API change.
