Materials for "Getting started with Open Source" at DevPulseCon
This repository contains information to help you get started with contributing to an open source project on GitHub. As part of this session, you will contribute a small change to this project to familiarise yourself with a typical workflow for contributing to projects on GitHub. You'll be adding your name and GitHub user name to this page.
- GitHub account
- git installed on your local machine
If you're new to git, you can learn the basics in your browser using Try Git.
Click the "Fork" button at the top right of this page. You should now have a copy of this repository available on your own account. You can make changes and freely experiment knowing that you won't be affecting the upstream repository.
This copies the entire repository, including all history, to your local machine.
git clone https://github.com/<username>/open-source-intro.git
Choose a short but descriptive name for your branch. This will help you identify it amongst other branches.
cd open-source-intro
git checkout -b add-<name>-to-attendees
This command creates a new branch and switches the working branch to the newly created one.
Open the file attendees.json in your editor of choice.
Add a JSON object to the attendees array in the following format:
{
"name": "<Your name>",
"username": "<Your github username>"
}
You can check the status of the repository and see which files have been modified using the following command:
git status
You can check that your changes are as expected:
git diff
Before committing the changes, we need to "stage" them first.
git add attendees.json
Once we've staged all of our changes, we commit them:
git commit -m "Add <Your Name> to attendees."
* If this is your first time using git on your local machine, you will be asked at this point to input your name and email address.
This is necessary as git uses this information in the commit metadata and GitHub identifies your commits by email address.
Ensure that you use the same email address for both your GitHub account and git configuration.
```
git config --global user.name "<Your Name>"
git config --global user.email "<email address used on github account>"
```
Once you've added this information, run the `git commit` step from before.
You can now check the logs and see your commit
git log
Pushing your changes will make them publicly available on your GitHub repository.
git push --set-upstream origin <branch-name>
Once you've pushed all the changes you want to make, it's time to create a pull request to contribute the changes back upstream.
To create a pull request, go to the branches section on your GitHub repository. Within this page, you should see your branch listed, and to the right of it, a button which says "New Pull Request". Click this button. The "Open a pull request" page allows you to write a title and comment for your pull request and allows you to compare your branch against the target branch in the upstream repository. Once you're happy with the description, click "Create pull request".
Once you've created your PR, the project maintainers will review your change and decide whether it should be merged. If changes are suggested, you can continue to make changes on your original branch and the pull request will be updated accordingly.
If the project maintainers are satisfied with your changes, they may merge your pull request. Congratulations! You will have made a contribution to an open source project!
