ryan-tools

ryan-tools is a collection of Python utilities for TUFLOW, RORB, 12D, GDAL, QGIS and general data-processing workflows. Reusable code lives in ryan_library; files under ryan-scripts are human-facing wrappers and standalone utilities.

The distribution is named ryan_functions, while maintained imports normally use ryan_library.

Project status

The repository targets Python 3.14. Maintained library code, orchestrators and unversioned wrappers follow the current repository standards; older standalone, versioned and compatibility files remain where they still support migration or narrow workflows.

Start with:

• Development guide for architecture, code categories, lifecycle terms and validation.
• Environment guide for Python, VS Code, installed-wheel and QGIS/OSGeo4W setup.
• Ryan Scripts guide for choosing and safely running scripts.
• Maintained wrapper standard when changing a library-backed wrapper.
• Project documentation index for setup guides, roadmaps and dated audits.
• Examples for direct library use when an existing wrapper is not the right fit.

Set up the repository

This repository uses Git submodules and Git LFS for workbook resources. Install Git LFS, then clone recursively:

git lfs install
git clone --recurse-submodules https://github.com/Chain-Frost/ryan-tools.git
cd ryan-tools
git lfs pull
git -C qgis-resources lfs pull
git -C excel-resources lfs pull

For an existing clone:

git submodule update --init --recursive
git lfs pull
git -C qgis-resources lfs pull
git -C excel-resources lfs pull

The test suite requires tests/test_data; it does not download or substitute those fixtures automatically.

Install the repository requirements into the user's normal Python 3.14 installation. ryan-tools does not require or assume that users know how to create or activate a virtual environment:

py -3.14 -m pip install --upgrade pip
py -3.14 repo-scripts\install_latest_wheel.py --dependencies-only
py -3.14 -m pip install -r requirements.txt

requirements.txt installs the checkout and development tools into that Python installation. Installing the project is important when running wrappers copied outside the repository because they import the shared implementation from the installed ryan_functions distribution. The dependency bootstrap installs binary Fiona, Rasterio and GDAL packages from the configured geospatial wheel index, avoiding a local source build on Windows.

Build and install

After changing ryan_library or package metadata, rebuild from the repository root:

python repo-scripts/build_library.py

The build script updates the version in pyproject.toml and creates the wheel under dist/. Use --skip-pip when the build dependency is already installed, or --skip-artifacts in an environment that cannot create or retain wheel artifacts. Wheel builds require the QGIS resource submodule because setup.py stages the pinned TUFLOW QML styles into the package.

Windows convenience entry points are:

.\package_and_install.bat
.\install-latest-wheel.bat

The first builds and installs the package; the second installs the newest existing wheel.

Test changes

Use focused pytest commands for a bounded change. Keep temporary files under the repository on this Windows checkout:

python -m pytest tests\path\to\test_file.py --basetemp=.pytest_cache\basetemp

Run the complete suite through the repository runner:

cmd.exe /C repo-scripts\run_tests.bat

The runner configures the source and bundled HY-8 import paths, uses a repository-local base temporary directory and generates terminal, HTML and XML coverage reports. See the development guide for proportional validation expectations.

Parse a TUFLOW result filename

TuflowStringParser extracts the configured data type and run metadata from a result path:

from pathlib import Path

from ryan_library.classes.tuflow_string_classes import TuflowStringParser

parser = TuflowStringParser(Path("M11_01p_00120m_TP01_1d_Q.csv"))

print(parser.data_type)
print(parser.raw_run_code)
print(parser.clean_run_code)
print(parser.aep)
print(parser.duration)
print(parser.tp)

The authoritative suffix registry is ryan_library/classes/tuflow_results_validation_and_datatypes.json. It contains both processor-backed tabular types and raster classifications used for discovery.

Load TUFLOW data for exploration

load_tuflow_data() handles discovery, logging, serial or parallel processing and optional location filtering:

from ryan_library.functions.tuflow.notebook_helpers import load_tuflow_data

collection = load_tuflow_data(
    paths=["results"],
    data_types=["Q", "V", "H", "Nmx", "Cmx", "Chan", "EOF"],
    parallel=True,
    locations=["Culvert_01"],
)

timeseries = collection.combine_1d_timeseries()
maximums = collection.combine_1d_maximums()

Processor-backed types currently include POMM, PO, Cmx, Nmx, Chan, ccA, RLL_Qmx, Q, H, CF, V, EOF and TLF. Use the processor development notes for combination behavior, caching and extension guidance.

Run a ready-made TUFLOW workflow

Orchestrators are callable workflow controllers; wrappers add editable defaults, CLI handling, banners, exit codes and optional pauses:

from pathlib import Path

from ryan_library.orchestrators.tuflow.tuflow_culverts_merge import main_processing

main_processing(
    paths_to_process=[Path("results")],
    include_data_types=["Nmx", "Cmx", "Chan", "ccA", "RLL_Qmx", "EOF"],
    locations_to_include=["Culvert_01"],
    output_dir=Path("outputs"),
    export_mode="both",
)

Representative orchestrators cover culvert maximums and time series, PO/POMM combination, closure durations, peak and stability checks, TUFLOW log summaries and result styling. The corresponding maintained wrappers are under ryan-scripts/TUFLOW-python; use that folder's README and each wrapper's --help output as the current interface.

Use other library helpers

RORB hydrograph discovery and parsing:

from pathlib import Path

from ryan_library.functions.RORB.read_rorb_files import find_batch_files, parse_batch_output

batch_files = find_batch_files([Path("rorb_outputs")])
runs = [parse_batch_output(path) for path in batch_files]

12D culvert export processing:

from pathlib import Path

from ryan_library.functions.process_12D_culverts import get_combined_df_from_files

culverts = get_combined_df_from_files(Path("12d_exports"))

For GDAL raster conversion, mosaics, flood extents, footprints, metadata and point-cloud conversion, use the maintained GDAL Python wrappers. The BAT files that remain under ryan-scripts/gdal-bat are legacy migration references and should not be selected for new work.

Excel and QGIS resources

The resource submodules contain project templates and application assets:

• excel-resources/workbooks/: Excel templates for hydrology, frequency and culvert workflows.
• qgis-resources/processing-models/tuflow/: QGIS models for common TUFLOW input layers.
• qgis-resources/processing-models/tuflow/supporting-workbooks/: formula-driven supporting workbooks used by relevant models.
• qgis-resources/styles/: QML styles, QPT layouts and supporting spatial assets.
• qgis-resources/scripts/: QGIS Python console and PyQGIS utilities.

Except for the TUFLOW QML files staged into wheel builds, treat these resources as project templates rather than files installed with the Python package. The parent repository pins each submodule to a reviewed commit.

Repository automation

• Pull request template records summaries, validation and review checklists.
• Code-review instructions describe repository-specific review expectations.
• Development guide is the canonical architecture and validation reference.
• MCP setup documents the repository's read-only discovery and inspection tools for AI clients.
