You want to contribute to kiuatan? Awesome.
There are a number of ways to contribute. As this document is a little long, feel free to jump to the section that applies to you currently:
Additional notes regarding formatting:
First of all please search existing issues to make sure your issue hasn't already been reported. If you cannot find a suitable issue — create a new one.
Provide the following details:
- short summary of what you were trying to achieve,
- a code snippet causing the bug,
- expected result,
- actual results and
- environment details: at least operating system version
If possible, try to isolate the problem and provide just enough code to demonstrate it. Add any related information which might help to fix the issue.
This project uses a fairly standard GitHub pull request workflow. If you have already contributed to a project via GitHub pull request, you can skip this section and proceed to the specific details of what we ask for in a pull request. If this is your first time contributing to a project via GitHub, read on.
Here is the basic GitHub workflow:
- Fork this repo. you can do this via the GitHub website. This will result in you having your own copy of the repo under your GitHub account.
- Clone your forked repo to your local machine
- Make a branch for your change
- Make your change on that branch
- Push your change to your repo
- Use the github ui to open a PR
Some things to note that aren't immediately obvious to folks just starting out:
- Your fork doesn't automatically stay up to date with changes in the main repo.
- Any changes you make on your branch that you used for one PR will automatically appear in another PR so if you have more than 1 PR, be sure to always create different branches for them.
- Weird things happen with commit history if you don't create your PR branches off of
mainso always make sure you have themainbranch checked out before creating a branch for a PR
If you feel overwhelmed at any point, don't worry, it can be a lot to learn when you get started. You can usually find me on the Pony IRC if you need help.
You can get help using GitHub via the official documentation. Some hightlights include:
Before issuing a pull request we ask that you squash all your commits into a single logical commit. While your PR is in review, we may ask for additional changes, please do not squash those commits while the review is underway. Once everything is good, I'll then ask you to further squash those commits before merging. We ask that you not squash while a review is underway as it can make it hard to follow what is going on. Additionally, we ask that you:
- Write a good commit message
- Issue 1 Pull Request per feature. Don't lump unrelated changes together.
If you aren't sure how to squash multiple commits into one, Steve Klabnik wrote a handy guide that you can refer to.
Once those conditions are met, the PR can be merged.
Please note, if your changes are purely to things like README, CHANGELOG etc, you can add [skip ci] as the last line of your commit message and your PR won't be run through our continuous integration systems. We ask that you use [skip ci] where appropriate as it helps to get changes through CI faster and doesn't waste resources that TravisCI is kindly donating to the Open Source community.
When contributing to documentation, try to keep the following style guidelines in mind:
As much as possible all documentation should be textual and in Markdown format. Diagrams are often needed to clarify a point. For any images, an original high-resolution source should be provided as well so updates can be made.
Documentation is not "source code." As such, it should not be wrapped at 80 columns. Documentation should be allowed to flow naturally until the end of a paragraph. It is expected that the reader will turn on soft wrapping as needed.
All code examples in documentation should be formatted in a fashion appropriate to the language in question.
All command line examples in documentation should be presented in a copy and paste friendly fashion. Assume the user is using the bash shell. GitHub formatting on long command lines can be unfriendly to copy-and-paste. Long command lines should be broken up using \ so that each line is no more than 80 columns. Wrapping at 80 columns should result in a good display experience in GitHub. Additionally, continuation lines should be indented two spaces.
OK:
my_command --some-option foo --path-to-file ../../wallaroo/long/line/foo \
--some-other-option barNot OK:
my_command --some-option foo --path-to-file ../../wallaroo/long/line/foo --some-other-option barWherever possible when writing documentation, favor full command options rather than short versions. Full flags are usually much easier to modify because the meaning is clearer.
OK:
my_command --messages 100Not OK:
my_command -m 100The basics:
- Indentation
Indent using spaces, not tabs. Indentation is language specific.
- Watch your whitespace!
Use an editor plugin to remove unused trailing whitespace including both at the end of a line and at the end of a file. By the same token, remember to leave a single newline only line at the end of each file. It makes output files to the console much more pleasant.
- Line Length
We all have different sized monitors. What might look good on yours might look like awful on another. Be kind and wrap all lines at 80 columns unless you have a good reason not to.
- Reformatting code to meet standards
Try to avoid doing it. A commit that changes the formatting for large chunks of a file makes for an ugly commit history when looking for changes. Don't commit code that doesn't conform to coding standards in the first place. If you do reformat code, make sure it is either standalone reformatting with no logic changes or confined solely to code whose logic you touched. For example, updating the indentation in a file? Do not make logic changes along with it. Editing a line that has extra whitespace at the end? Feel free to remove it.
