Installation and environment setup

Choosing an installation method

Use pip when consuming a published release:

python -m venv .venv
source .venv/bin/activate
python -m pip install deltae-resource

Use uv when developing RESource or reproducing an analysis from a repository checkout:

uv sync --locked

The package-index distribution name is deltae-resource; its import package and project name are RESource. Before the first PyPI release, use the locked source-checkout workflow instead.

The project metadata lives in pyproject.toml; exact development versions live in uv.lock. The legacy files under env/ are retained only as references for platforms where native geospatial wheels are unavailable.

Optional features

uv sync --locked --extra notebooks  # JupyterLab and widgets
uv sync --locked --extra viz        # Additional interactive plotting tools
uv sync --locked --extra docs       # Sphinx documentation toolchain

Development tools such as pytest and Ruff are in the dev dependency group and are installed by default during uv sync.

Repository layout

src/RESource/   Installable implementation
src/RES/        Temporary compatibility namespace
tests/          Fast automated tests
config/         Example workflow configuration
notebooks/      Exploratory and case-study notebooks
docs/source/    Sphinx documentation sources
data/           Local/downloaded data, mostly excluded from packages
workflow/       Snakemake workflow assets

Because the package uses a src layout, importing directly from a fresh checkout without installing it is intentionally unsupported. Run commands with uv run or activate .venv first.

Dependency changes

Add runtime dependencies with:

uv add PACKAGE

Add development-only dependencies with:

uv add --group dev PACKAGE

Add an optional feature dependency with:

uv add --optional notebooks PACKAGE

Commit both pyproject.toml and uv.lock after a dependency change.

Validation

uv lock --check
uv run resource --help
uv run pytest
uv run ruff check src tests
uv run ruff format --check src tests
uv build

The build should produce a wheel and source archive in dist/. Test the wheel before publishing to ensure the result does not depend on repository-relative imports.

Native geospatial dependencies

Most supported platforms receive wheels for Rasterio, Fiona, PyProj, Shapely, and GeoPandas. On an HPC or unusual platform without compatible wheels, install the required GDAL/PROJ system libraries first or use a Conda/micromamba base environment, then install RESource into that environment.

Data location

Large assessment data is intentionally outside the wheel. Configuration files normally provide data paths. The EU DEM pipeline additionally recognizes RESOURCE_DATA_DIR:

export RESOURCE_DATA_DIR=/path/to/resource-data
uv run python -m RESource.eu_dem_pipeline --help
