Feature requests and feedback

Do you like intake-stac? Share some love on Twitter or in your blog posts!

We’d also like to hear about your propositions and suggestions. Feel free to submit them as issues and:

  • Explain in detail how they should work.
  • Keep the scope as narrow as possible. This will make it easier to implement.

Report bugs

Report bugs for intake-stac in the issue tracker.

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, specifically the Python interpreter version, installed libraries, and intake-stac version.
  • Detailed steps to reproduce the bug.

If you can write a demonstration test that currently fails but should pass (xfail), that is a very useful commit to make as well, even if you cannot fix the bug itself.

Fix bugs

Look through the GitHub issues for bugs.

Talk to developers to find out how you can fix specific bugs.

Write documentation

intake-stac could always use more documentation. What exactly is needed?

  • More complementary documentation. Have you perhaps found something unclear?
  • Docstrings. There can never be too many of them.
  • Blog posts, articles and such – they’re all very appreciated.

You can also edit documentation files directly in the GitHub web interface, without using a local copy. This can be convenient for small fixes.

Note

Build the documentation locally with the following command:

$ conda env update -f ci/environment-dev-3.7.yml
$ cd docs
$ make html

The built documentation should be available in the docs/_build/.

Preparing Pull Requests

  1. Fork the intake-stac GitHub repository. It’s fine to use intake-stac as your fork repository name because it will live under your user.

  2. Clone your fork locally using git and create a branch:

    $ git clone git@github.com:YOUR_GITHUB_USERNAME/intake-stac.git
    $ cd intake-stac
    
    # now, to fix a bug or add feature create your own branch off "master":
    
    $ git checkout -b your-bugfix-feature-branch-name master
    
  3. Install pre-commit and its hook on the intake-stac repo:

    $ pip install --user pre-commit
    $ pre-commit install
    

    Afterwards pre-commit will run whenever you commit.

    https://pre-commit.com/ is a framework for managing and maintaining multi-language pre-commit hooks to ensure code-style and code formatting is consistent.

  4. Install dependencies into a new conda environment:

    $ conda env update -f ci/environment-dev-3.7.yml
    
  5. Run all the tests

    Now running tests is as simple as issuing this command:

    $ conda activate intake-stac-dev
    $ pytest --junitxml=test-reports/junit.xml --cov=./ --verbose
    

    This command will run tests via the “pytest” tool against Python 3.7.

  6. You can now edit your local working copy and run the tests again as necessary. Please follow PEP-8 for naming.

    When committing, pre-commit will re-format the files if necessary.

  7. Commit and push once your tests pass and you are happy with your change(s):

    $ git commit -a -m "<commit message>"
    $ git push -u
    
  8. Finally, submit a pull request through the GitHub website using this data:

    head-fork: YOUR_GITHUB_USERNAME/intake-stac
    compare: your-branch-name
    
    base-fork: pangeo-data/intake-stac
    base: master
