Developer Guide#

Setting uo the Development Environment#

Setting up the development environment is a critical step in contributing to TEEHR. This guide will walk you through the steps to set up a development environment for TEEHR.

Install the prerequisites: - Python 3.10 or later - Poetry - Java 11 or later for Spark (we use 17)

1. Clone the TEEHR repository from GitHub: `bash git clone https://github.com/RTIInternational/teehr.git ` 2. Navigate to the TEEHR directory: `bash cd teehr ` 3. Create a new virtual environment using poetry: `bash poetry install ` 4. Activate the virtual environment: `bash poetry shell ` 5. Install the required JAR files for Spark: `bash python download_spark_jars.py `

Contributing Guidelines#

These contributing guidelines will be updated as we progress. They are pretty slim to start.

TEEHR has multiple parts, one is a library of reusable code that can be imported as a dependency to another project, another is examples and dashboards which are more use case specific (e.g., a dashboard to conduct post event analysis). The guidelines for contributing may be a bit different.

Library Code#

  • Use PEP 8

  • Use LFS for large files

  • Write tests - you are going to test your code, why not write an actual test pytest.

  • Use the Numpy doc string format numpydoc

Git LFS#

Use git lfs for large files. Even better keep large files out of the repo.

Notebooks#

  • Do not commit notebook output to the repo. Use can install and use nbstripout to strip output. After cloning, you must run nbstripout –install.

nbstripoutput is configured to strip output from notebooks to keep the size down and make diffing files easier. See kynan/nbstripout. The configuration is stored in the .gitattributes file, but the tool must be installed per repo. You may need to install the Python package first with conda install nbstripout or similar depending on your environment.

Local Development#

The most common way to use TEEHR is by installing it in a Python virtual environment. The document covers using a conda virtual environment, but there is no hard requirement to do so. In this case the packages are not installed, so you need to make sure you add src/ to your Python path. There are two way to do this below, but depending on your development environment, your milage may vary.

Release Process#

This document describes the release process which has some manual steps to complete.

Create branch with the following updated to the new version (find and replace version number):

  • version.txt

  • README.md

  • pyproject.toml

  • src/teehr/__init__.py

  • docs/sphinx/getting_started/index.rst

Update the changelog at docs/sphinx/changelog/index.rst to reflect the changes included in the release.

If also pushing changes to TEEHR-HUB, also update tags in teehr-hub/helm-chart/config.yaml.

Make a PR to main. After PR has been reviewed and merged, checkout main pull changes and tag the commit.

git checkout main
git pull
git tag -a v0.x.x -m "version 0.x.x"
git push origin v0.x.x

Tagging will trigger a docker container build and push to the AWS registry for deployment to TEEHR-HUB. Deployment to TEEHR-HUB is a manual process that requires the correct credentials.

Contributing to the Documentation#

  • description

  • docstring approach (numpy)

  • pre-commit validation

  • building and pushing docs

The documentation files are in the docs/sphinx directory.

To build the documentation html files, navigate to docs/sphinx and run:

make clean html

Check your files locally in a browser such as Firefox:

firefox _build/html/index.html &

Some pre-commit hooks are configured automatically run when you commit some code. These check for things like large files, docstring formatting, added whitespace, etc. To run these manually and print the results to a text file pre-commit-output.txt, run:

pre-commit run --all-files > pre-commit-output.txt
