We've seen a bunch of ways to contribute: triaging issues & pull requests, creating pull requests and contributing to the documentation.
But there's so much more! The Symfony ecosystem is a lot bigger than just these two repositories. For example, go to github.com/symfony. Woh! There are 118 repositories under Symfony! Click on, for example,
This repository is what's called a "subtree split". Cool name, right? The DomCrawler component actually lives and is managed inside of the main
symfony/symfony repository that we've been working in. I'll show you: open that repository and navigate to
This is the DomCrawler component. An automated process splits this directory into its own repository so that people can use it independently. If you want to contribute to DomCrawler, you'll do it in
symfony/symfony. The sub-tree split is read-only.
How can you know if a repository is a sub-tree split? You'll notice that the "Issues" tab has been disabled.
Many of those 118 repositories under Symfony are subtree splits. And so, you contribute to them in the main repo. But a lot of them are normal repositories that you can contribute to directly. For example, recipes.
This is one of the coolest ways that you can help Symfony. If you install a bundle or library and it doesn't have a good recipe, or doesn't have a recipe at all, you should totally add or improve it! You can create a recipe here, or on the less-stringent
And there are a lot more - like
MonologBundle. The point is: each of these needs help triaging issues and reviewing pull requests. And actually, because these independent libraries get less traffic, you can make an even bigger difference in a short amount of time.
Let's make one small contribution to the recipes. Go back to the main recipes repository. One of the recipes is for the
twig/extensions library: a standalone PHP library. When you install that package, its recipe gives you a new
config/packages/twig_extension.yaml file. These are the four classes provided by that library. After installing the library, you just need to uncomment the ones that you want.
Let's make this even more obvious by adding a comment above to describe that.
To do that, go back to main recipes page and copy the clone URL. Hopefully, this process is starting to feel boring... and repetitive. At your terminal, move back into the
contributing/ directory and clone that:
git clone email@example.com:symfony/recipes.git
Then, move inside. To create a pull request, we will eventually need our own fork. I already have a fork, so I'll skip straight to copying my URL, going back to the terminal, and adding that remote:
git remote add weaverryan and paste.
git remote add weaverryan firstname.lastname@example.org:weaverryan/recipes.git
Back in the editor, I'll close a few files. Then open
Add the comment:
Uncomment any lines below to activate that Twig extension
|... lines 2 - 6|
|# Uncomment any lines below to activate that Twig extension|
Brilliant! Let's commit this! The recipes repository is a bit unique: it only has a
master branch. So, we'll create our new branch from it:
git checkout -b adding-twig-extensions-note
Then, add, commit
git add -ugit commit -m "Adding a small note about what to do in the twig_extensions.yaml file"
git push weaverryan adding-twig-extensions-note
Awesome! Go back to GitHub! Sweet! Here's the yellow bar: click "Compare & pull request". Add a small note about why we think this is a good idea. And, make sure we don't have any other "surprise" changes. Looks good. Hit "Create pull request".
This was a pretty simple change. But, when your changes are bigger, you'll probably want to be able to test your recipe before it's merged: to see how it works in the real world!
And... we can do that! Almost immediately after posting the PR, you'll hopefully see a message: "Pull request passes validation". This means that our changes passed a few rules that are described in this repository's README.
Another spot says "View deployment". Open that in a new tab. This is really cool. The Flex server just "deployed" our recipe. And we can temporarily change our Flex "endpoints" to use our new recipe... even though it's not merged yet!
export line, find a terminal and paste:
We just set an environment variable on this terminal tab only. To test the recipe, let's just move into one of our projects, like
composer require twig/extensions
When we run that, it gives us a warning that we're not using the normal Symfony endpoint... which is perfect. And... it looks like it worked!
Go check it out: open
config/packages/twig_extensions.yaml. We got it! No surprise for this small tweak. But for bigger changes, this is so useful.
When you're done playing with things, be sure to unset that variable so that you once again use the real Symfony endpoint:
Ok people, that's it! Oh, there is so much good stuff to work on in the Symfony world. And we need the help! There's complex stuff, like working on the main
symfony/symfony repository. But there are also many, many other ways to contribute, like improving the documentation, working on recipes or just finding that third party library or bundle you love and helping to improve it or its docs. You are the person that can make a difference by adding that feature or fixing that bug.
And if you have more questions on contributing, ask them down in the comments! We would love to help answer them
Ok people, seeya on GitHub!
