It looks like Colin did a great job with this new feature.
But, we can give a merger much more confidence by actually testing it in a real project!
In PhpStorm, I've already created an empty contributing directory.
And, I already have a terminal open to this same place.
To test the PR, let's literally create a brand-new Symfony app:
composer create-project symfony/skeleton.
I'm using symfony/skeleton instead of the larger symfony/website-skeleton to keep things
as small and focused as possible.
Grab the dev-master version of the skeleton.
Why? Colin's PR is against Symfony's master branch.
So, to test it, I want to create an app that's based on that same version of Symfony.
Finally, put this into a new directory called triage_pr_28069:
When that finishes, move over and...
yea! Here's the new app.
Check out its composer.json file: it's using version 4.2 of Symfony, which is the next,
unreleased, version of Symfony at this moment.
In other words, this code is from Symfony's master branch.
We also have minimum-stability set to dev, which means that Composer will try
to install new, unreleased version of libraries.
Look back at the PR: all of the changes were to the Validator component.
Ok, let's get that installed: find your terminal, move into the directory and run:
composer require validator This will install the dev-master version of symfony/validator.
In other words, it will get the code from Symfony's master branch.
But... hmm...
that's not quite what we want: we somehow need to get the code from Colin's branch.
How can we do that?
Oh, it's super cool.
Go to your terminal and open a new tab.
Go back up to the contributing directory.
I'm going to clone the entire Symfony project into a new directory here.
To do that, go back to your browser, move to the repository's homepage,
click "Clone or download" and copy the URL.
Move back over, git clone and paste: When that finishes,
we now have a symfony directory right next to our app.
To get Colin's branch, we have a few options.
Move into the new symfony directory and type: git remote
and git remote show origin Let's add a second remote for Colin's fork.
Copy the Symfony URL, then run git remote add and paste.
Copy Colin's username - colinodell, move back, call the new remote colinodell,
and change the username part of the URL: Nice!
Grab his branches with: git fetch colinodell Yep!
There's the branch:
feature/multiple-of-validator - this is the one used for the PR.
To check out to that code, create a new branch:
git checkout -b feature/multiple-of-validator colinodell/feature/multiple-of-validator Sweet!
To prove we've got the right code, go back to PhpStorm,
press Shift+Shift, and search for the new file.
There it is!
We now have a test app and the new code in our symfony directory.
But, they're not connected yet!
Let's do that next.
