Contributing

Bug reports, feature suggestions, and other contributions are greatly appreciated! pyValEIA is a community-driven project and welcomes both feedback and contributions.

Short version

Submit bug reports, feature requests, and questions at GitHub
Make pull requests to the develop branch

Issues

Bug reports, questions, and feature requests should all be made as GitHub Issues. Templates are provided for each type of issue, to help you include all the necessary information.

Questions ^^^^^^^^^

Not sure how something works? Ask away! The more information you provide, the easier the question will be to answer. You can also search the closed issues for potential answers to your questions.

Bug reports ^^^^^^^^^^^

When reporting a bug please include:

Your operating system name and version
Any details about your local setup that might be helpful in troubleshooting
Detailed steps to reproduce the bug

Feature requests and feedback ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The best way to send feedback is to file an issue.

If you are proposing a new feature or a change in something that already exists:

Explain in detail how it would work.
Keep the scope as narrow as possible, to make it easier to implement.
Remember that this is a volunteer-driven project, and that code contributions are welcome :)

Development

To set up pyValEIA for local development:

Fork pyValEIA on GitHub.
Clone your fork locally:

  git clone git@github.com:your_name_here/pyValEIA.git

Create a branch for local development:

git checkout -b name-of-your-bugfix-or-feature

Now you can make your changes locally.

Tests for custom functions should be added to the appropriately named file in pyValEIA/tests. For example, custom functions for the grid utilities are tested in pyValEIA/tests/test_utils_coords.py. If no test file exists, then you should create one. This testing uses unittest, which will run tests on any Python file in the test directory that starts with test. Classes must begin with Test, and methods must begin with test as well.

When you’re done making changes, run all the checks to ensure that nothing is broken on your local system, as well as check for flake8 compliance:
```
 python -m unittest discover
```
You should also check for flake8 style compliance:
```
flake8 . --count --select=D,E,F,H,W --show-source --statistics
```
Note that pyValEIA tests for uniformity in docstring formatting.
Update/add documentation (in docs). Even if you don’t think it’s relevant, check to see if any existing examples have changed.
Add your name, affiliation, and ORCiD to the CITATION.cff file as an author
Commit your changes:
```
git add .
git commit -m "AAA: Brief description of your changes"
```
Where AAA is a standard shorthand for the type of change (e.g., BUG or DOC). pyValEIA follows the numpy development workflow, see the discussion there for a full list of this shorthand notation.
Once you are happy with the local changes, push to GitHub:
```
git push origin name-of-your-bugfix-or-feature
```
Note that each push will trigger the Continuous Integration workflow.
Submit a pull request through the GitHub website. Pull requests should be made to the develop branch. Note that automated tests will be run on GitHub Actions, but these must be initialized by a member of the pyIntensityFeatures team for first time contributors.

Pull Request Guidelines

If you need some code review or feedback while you’re developing the code, just make a pull request. Pull requests should be made to the develop branch.

For merging, you should:

Include an example for use
Add a note to CHANGELOG.md about the changes
Update the author list in CITATION.cff, if applicable
Ensure that all checks passed (e.g., GitHub Actions, Coveralls, and ReadTheDocs)

If you don’t have all the necessary Python versions available locally or have trouble building all the testing environments, you can rely on GitHub Actions to run the tests for each change you add in the pull request. Because testing here will delay tests by other developers, please ensure that the code passes all tests on your local system first.

Project Style Guidelines

In general, pyValEIA follows PEP8 and numpydoc guidelines. unittest runs the unit and integration tests, flake8 checks for style, and sphinx-build performs documentation tests. However, there are certain additional style elements that have been adopted to ensure the project maintains a consistent coding style. These include:

Line breaks should occur before a binary operator (ignoring flake8 W503)
Combine long strings using join
Preferably break long lines on open parentheses rather than using \
Use no more than 80 characters per line
The pyVAlEIA logger is imported into each sub-module and provides status updates at the info and warning levels (as appropriate)
Several dependent packages have common nicknames, including:
- import datetime as dt
- import numpy as np
- import pandas as pd
When incrementing a timestamp, use dt.timedelta instead of pds.DateOffset when possible to reduce program runtime
All classes should have __repr__ and __str__ functions
Avoid creating a try/except statement where except passes
Provide testing class methods with informative failure statements and descriptive, one-line docstrings
Block and inline comments should use proper English grammar and punctuation with the exception of single sentences in a block, which may then omit the final period. Both British and American spelling is permitted.
