If you are new to Yearn Finance, you might want to familiarize yourself with its core concepts and products. You can also join the discord channel if you have questions or to keep up with updates.
Before proceeding, please set up your environment by following these installation, building and testing instructions.
Each time you begin a set of changes, ensure that you are working on a new branch that you have created as opposed to the main of your local repository. By keeping your changes segregated in this branch, merging your changes into the main repository later will be much simpler for the team.
To create a local branch for git to checkout, issue the command:
git checkout -b feature-in-progress-branchTo checkout a branch you have already created:
git checkout feature-in-progress-branchThe official yearn-vaults repository may have changed since the time you cloned it. To fetch changes to the yearn-vaults repository since your last session:
git fetch originThen synchronize your master branch:
git pull origin master
To stage the changed files that are be committed, issue the command:
git add --allOnce you are ready to make a commit, you can do so with:
git commit -m “fix: message to explain what the commit covers”NOTE: commit message must follow Conventional Commits standard, otherwise your pull requests (discussed further below below) will not pass validation tests. You can use the --amend flag to effectively change your commit message.
If there are conflicts between your edits and those made by others since you started work Git will ask you to resolve them. To find out which files have conflicts, run:
git statusOpen those files, and you will see lines inserted by Git that identify the conflicts:
<<<<<< HEAD
Other developers’ version of the conflicting code
======
Your version of the conflicting code
'>>>>> Your Commit
The code from the yearn-vaults repository is inserted between <<< and === while the change you have made is inserted between === and >>>>. Remove everything between <<<< and >>> and replace it with code that resolves the conflict. Repeat the process for all files listed by Git status to have conflicts.
When you are ready, use git push to move your local copy of the changes to your fork of the repository on Github.
git push [email protected]:<your_github_username>/yearn-vaults.git feature-in-progress-branchNavigate to your fork of the repository on Github. In the upper left where the current branch is listed, change the branch to your newly created one (feature-in-progress-branch). Open the files that you have worked on and ensure they include your changes.
Navigate to yearn-vault repository and click on the new pull request button. In the “base” box on the left, leave the default selection “base main”, the branch that you want your changes to be applied to. In the “compare” box on the right, select the branch containing the changes you want to apply. You will then be asked to answer a few questions about your pull request. Pull requests should have enough context about what you are working on, how you are solving a problem, and reference all necessary information for your reviewers to help.
After you complete the questionnaire, the pull request will appear in the list of pull requests.
Core developers may ask questions and request that you make edits. If you set notifications at the top of the page to “not watching,” you will still be notified by email whenever someone comments on the page of a pull request you have created. If you are asked to modify your pull request, edit your local branch, push up your fixes, then leave a comment to notify the original reviewer that the pull request is ready for further review.
