Contributing

Contributions are welcome, and they are greatly appreciated! Every little bit helps, and credit will always be given.

You can contribute in many ways:

Types of Contributions

Report Bugs

Report bugs at https://github.com/primap-community/climate_categories/issues.

If you are 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.

Fix Bugs

Look through the GitHub issues for bugs. Anything tagged with “bug” and “help wanted” is open to whoever wants to implement it.

New categorizations

Especially welcome are new categorizations, which are not included in climate_categories so far. Pull requests and issue reports at github are very welcome!

The categorizations are read from StrictYaml files located at climate_categories/data/. You can write a yaml definition by hand, but ideally, categorizations are generated from some canonical source automatically, so that the generation is reproducible and transparent. Scripts to generate categorizations are located in the data_generation folder and write their results directly to climate_categories/data/. For each data file, a target should be included in the top-level Makefile. Do not include source pdfs with non-free copyright licenses into the git repository. Instead, download them in the data generation scripts (see data_generation/IPCC2006.py for an example how to do that efficiently with caching).

Because all Categorizations are read in when importing climate_categories and parsing StrictYaml files is not very efficient, the categories should be also stored as cached Python files using the to_python instance method. Run make cache to generate these from the YAML files.

New conversions

Especially welcome as well are new conversions between categorizations, which are not included in climate_categories so far. Pull requests and issue reports at github are very welcome!

The conversions are read from CSV files located at climate_categories/data/. You can write a CSV definition by hand, but ideally, conversions are also generated from some canonical source automatically, so that the generation is reproducible and transparent. As the scripts to generate categorizations, the scripts to generate conversion files are located in the data_generation folder and write their results directly to climate_categories/data/.

Conversion files are read on demand and therefore no pickle files need to be generated.

Write Documentation

Climate categories could always use more documentation, whether as part of the official Climate Categories docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback

The best way to send feedback is to file an issue at https://github.com/primap-community/climate_categories/issues.

If you are proposing a feature:

Explain in detail how it would work.
Keep the scope as narrow as possible, to make it easier to implement.
Remember that contributions are welcome :)

Get Started!

Ready to contribute? Here’s how to set up climate_categories for local development.

Fork the climate_categories repo on GitHub.

Clone your fork locally:

$ git clone git@github.com:your_name_here/climate_categories.git

Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:
```
$ cd climate_categories/
$ make virtual-environment
$ make install-pre-commit
```
Create a branch for local development:
```
$ git checkout -b name-of-your-bugfix-or-feature
```
Now you can make your changes locally.
When you’re done making changes, check that your changes pass our tests and automatically format everything according to our rules:
```
$ make lint
```
Often, the linters can fix errors themselves, so if you get failures, run make lint again to see if any errors need human intervention.

Commit your changes and push your branch to GitHub:

$ git add .
$ git commit -m "Your detailed description of your changes."
$ git push origin name-of-your-bugfix-or-feature

Submit a pull request through the GitHub website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

The pull request should include tests.
If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring and check the generated API documentation.

Deploying

A reminder for the maintainers on how to deploy.

1. Run `tbump`

commit all your changes
make sure gh is installed on your system
Decide what the new version number should be
For version X.Y.Z - increase X for a major release, increase Y when breaking changes are introduced, increase Z for minor changes
Run venv/bin/tbump X.Y.Z

2. Update the README

Run make README.rst to update the citation information in the README from the zenodo API.
Check if the version is actually correct. You can look at the diff for the README and check if the DOI and the date has changed
If it’s not updated, grab a tea and wait a little more for zenodo to mint the new version.
Once it’s there, push new README to github

3. Publish on PyPi

make sure you have a pypi account
make sure you have the rights to publish on pypi, if not ask a project owner to add you
create a file called .pypirc in your home directory, more info on the pypirc file here
Write the following text in the file:

[distutils]
  index-servers =
    climate-categories

[climate-categories]
  repository = https://upload.pypi.org/legacy/
  username = __token__
  password = pypi-PASSWORD

change the password to your personal token. You can generate the token on the settings page of climate_categories on pypi.
run make release
click on the pypi link in the command line and check if everything makes sense
if something went wrong you can revert the release by clicking options -> yank
