Contributing

Here are the guidelines we'd like you to follow:

Development

Any contributor of this project should follow:

Found an Issue or Bug?

Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.

A minimal reproduce scenario allows us to quickly confirm a bug (or point out config problems) as well as confirm that we are fixing the right problem.

We will be insisting on a minimal reproduce scenario in order to save maintainers time and ultimately be able to fix more bugs. We understand that sometimes it might be hard to extract essentials bits of code from a larger code-base but we really need to isolate the problem before we can fix it.

Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you we are going to close an issue that doesn't have enough info to be reproduced.

Feature Requests?

You can request a new feature by creating an issue on GitHub.

If you would like to implement a new feature, please submit an issue with a proposal for your work first, to be sure that particular feature makes sense for the project.

Once the issue submitted, always start your feature from creating a new branch from develop and not master as we may have some features still not ready to be merged to master yet.

Pull Request Submission Guidelines

Before you submit your Pull Request (PR) consider the following guidelines:

  • Search Github for an open or closed PR that relates to your submission. You don't want to duplicate effort;
  • Commit your changes using a descriptive commit message that follows our commit message conventions. Adherence to these conventions is necessary because release notes are automatically generated from these messages;
  • Fill out our Pull Request Template. Your pull request will not be considered if it is ignored.

Commit Conventions

Each commit message consists of a header, a body and a footer.

The header has a special format that includes a type, a scope and a subject:

{type}({scope}): {subject}
{BLANK LINE}
{body}
{BLANK LINE}
{footer}

The header is mandatory and the scope of the header is optional.

Any line of the commit message cannot be longer than 100 characters. This allows the message to be easier to read on GitHub as well as in various git tools.

The footer should contain a closing reference to an issue if any.

Examples:

docs(readme): update error codes

fix: refer to the `entrypoint` instead of the first `module`

Header

Type

Must be one of the following:

  • build: Changes that affect the build system or external dependencies (example: npm);
  • chore: Changes that fall outside of build / docs that do not effect source code (examples: package, defaults);
  • ci: Changes to CI configuration files and scripts (examples: circleci, travis);
  • docs: Documentation-only changes (examples: readme, changelog);
  • feature: A new feature;
  • fix: A bug fix;
  • perf: A code change that improves performance;
  • refactor: A code change that neither fixes a bug nor adds a feature;
  • revert: Used when reverting a committed-change;
  • style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons);
  • test: Addition of or updates to tests.

Scope

The scope is subjective and depends on the type see above. A good example would be a change to a particular class/module.

Subject

The subject contains a succinct description of the change:

  • use the imperative, present tense: "change" not "changed" nor "changes";
  • don't capitalize the first letter;
  • no dot (".") at the end.

Body

Just as in the subject, use the imperative, present tense: "change" not "changed" nor "changes". The body should include the motivation for the change and contrast this with previous behavior.

Footer

The footer should contain any information about Breaking Changes and is also the place to reference GitHub issues that this commit Closes.

Breaking Changes should start with the word BREAKING CHANGE: with a space or two new lines and the rest of the commit message.

Revert

If the commit reverts a previous commit, it should begin with revert:, followed by the header of the reverted commit. In the body it should say: This reverts commit {hash}., where the hash is the SHA of the commit being reverted.

Thank you

Thank you for your interest, time, understanding, and for following this guide.
