The following is a set of guidelines for contributing to the Flow core contracts. These are mostly guidelines, not rules. Use your best judgment, and feel free to propose changes to this document in a pull request.
You are free to contribute however you want! You can submit a bug report in an issue, suggest an enhancment, or even just make a PR for us to review. We just ask that you are clear in your communication and documentation of all your work so we can understand how you are trying to help.
- Search existing issues to see if the problem has already been reported. If it has and the issue is still open, add a comment to the existing issue instead of opening a new one.
Explain the problem and include additional details to help maintainers reproduce the problem:
- Use a clear and descriptive title for the issue to identify the problem.
- Describe the exact steps which reproduce the problem in as many details as possible. When listing steps, don't just say what you did, but explain how you did it.
- Provide specific examples to demonstrate the steps. Include links to files or GitHub projects, or copy/pasteable snippets, which you use in those examples. If you're providing snippets in the issue, use Markdown code blocks.
- Describe the behavior you observed after following the steps and point out what exactly is the problem with that behavior.
- Explain which behavior you expected to see instead and why.
- Include screenshots and animated GIFs which show you following the described steps and clearly demonstrate the problem. You can use this tool to record GIFs on macOS and Windows, and this tool or this tool on Linux.
Provide more context by answering these questions:
- Can you reliably reproduce the issue? If not, provide details about how often the problem happens and under which conditions it normally happens.
Include details about your configuration and environment:
- What's the name and version of the OS you're using?
- What's the name and version of the flow-cli that you are using?
- Perform a cursory search to see if the enhancement has already been suggested. If it has, add a comment to the existing issue instead of opening a new one.
Enhancement suggestions are tracked as GitHub issues. Create an issue and provide the following information:
- Use a clear and descriptive title for the issue to identify the suggestion.
- Provide a step-by-step description of the suggested enhancement in as many details as possible.
- Provide specific examples to demonstrate the steps. Include copy/pasteable snippets which you use in those examples, as Markdown code blocks.
- Describe the current behavior and explain which behavior you expected to see instead and why.
- Include screenshots and animated GIFs. You can use this tool to record GIFs on macOS and Windows, and this tool or this tool on Linux.
- Explain why this enhancement would be useful to be included in the standard.
The process described here has several goals:
- Maintain code quality
- Fix problems that are important to users
Please follow the styleguides to have your contribution considered by the maintainers. Reviewer(s) may ask you to complete additional design work, tests, or other changes before your pull request can be ultimately accepted.
Before contributing, make sure to examine the project to get familiar with the patterns and style already being used.
- Use the present tense ("Add feature" not "Added feature")
- Use the imperative mood ("Move cursor to..." not "Moves cursor to...")
- Limit the first line to 72 characters or less
- Reference issues and pull requests liberally after the first line
