kwb.raindrop.binaries

Binary release artifacts for the kwb.raindrop R package.

This repository exists solely as a release container — it is not an R package and contains no source code. Each GitHub Release here ships one binary asset, downloaded on demand by the kwb.raindrop package.

Contents

Release tag pattern	Asset(s)	Loaded via
engine-<YYYY-MM-DD>	Regenwasserbewirtschaftung.exe (Windows)	kwb.raindrop::download_engine("<YYYY-MM-DD>")

Why a separate repository?

Hosting the binary releases in a dedicated repository keeps the main kwb.raindrop repository free of unrelated tags (engine-*, data-*) and avoids polluting its release history with binary-only artifacts.

Adding a new engine release

1. Create a new release: https://github.com/KWB-R/kwb.raindrop.binaries/releases/new
2. Tag: engine-<YYYY-MM-DD> (e.g. engine-2026-02-24).
3. Upload the executable as Regenwasserbewirtschaftung.exe — without the date in the filename; the date lives in the tag.
4. Mark as pre-release if desired, then publish.
5. Update the pinned default in R/download_engine.R (default_engine_version()) on the main package and open a PR.
