# Contributing to ruby-link-checker
This project is work of [many contributors](https://github.com/dblock/ruby-link-checker/graphs/contributors).
You're encouraged to submit [pull requests](https://github.com/dblock/ruby-link-checker/pulls), [propose features and discuss issues](https://github.com/dblock/ruby-link-checker/issues).
In the examples below, substitute your Github username for `contributor` in URLs.
### Fork the Project
Fork the [project on Github](https://github.com/dblock/ruby-link-checker) and check out your copy.
```
git clone https://github.com/contributor/ruby-link-checker.git
cd ruby-link-checker
git remote add upstream https://github.com/dblock/ruby-link-checker.git
```
### Bundle Install and Test
Ensure that you can build the project and run tests.
```
bundle install
bundle exec rake
```
## Contribute Code
### Create a Topic Branch
Make sure your fork is up-to-date and create a topic branch for your feature or bug fix.
```
git checkout main
git pull upstream main
git checkout -b my-feature-branch
```
### Write Tests
Try to write a test that reproduces the problem you're trying to fix or describes a feature that you want to build. Add tests to [spec](spec).
We definitely appreciate pull requests that highlight or reproduce a problem, even without a fix.
### Write Code
Implement your feature or bug fix.
Ruby style is enforced with [Rubocop](https://github.com/bbatsov/rubocop). Run `bundle exec rubocop` and fix any style issues highlighted, auto-correct issues when possible with `bundle exec rubocop -a`. To silence generally ingored issues, including line lengths or code complexity metrics, run `bundle exec rubocop --auto-gen-config`.
Make sure that `bundle exec rake` completes without errors.
### Write Documentation
Document any external behavior in the [README](README.md).
### Update Changelog
Add a line to [CHANGELOG](CHANGELOG.md) under *Next Release*. Don't remove *Your contribution here*.
Make it look like every other line, including a link to the issue being fixed, your name and link to your Github account.
### Commit Changes
Make sure git knows your name and email address:
```
git config --global user.name "Your Name"
git config --global user.email "contributor@example.com"
```
Writing good commit logs is important. A commit log should describe what changed and why.
```
git add ...
git commit
```
### Push
```
git push origin my-feature-branch
```
### Make a Pull Request
Go to https://github.com/contributor/ruby-link-checker and select your feature branch. Click the 'Pull Request' button and fill out the form. Pull requests are usually reviewed within a few days.
### Update CHANGELOG Again
Update the [CHANGELOG](CHANGELOG.md) with the pull request number. A typical entry looks as follows.
```
* [#123](https://github.com/dblock/ruby-link-checker/pull/123): Reticulated splines - [@contributor](https://github.com/contributor).
```
Amend your previous commit and force push the changes.
```
git commit --amend
git push origin my-feature-branch -f
```
### Rebase
If you've been working on a change for a while, rebase with upstream/main.
```
git fetch upstream
git rebase upstream/main
git push origin my-feature-branch -f
```
### Check on Your Pull Request
Go back to your pull request after a few minutes and see whether it passed muster with Travis-CI. Everything should look green, otherwise fix issues and amend your commit as described above.
### Be Patient
It's likely that your change will not be merged and that the nitpicky maintainers will ask you to do more, or fix seemingly benign problems. Hang on there!
## Thank You
Please do know that we really appreciate and value your time and work. We love you, really.
