Git development with Fork on macOS
This is a step-by-step tutorial on how to manage your site’s source code by using Fork on macOS. Fork is a fast and simple git client for Mac and Windows, and Presslabs friendly, too.
In this tutorial, we will show you how to easily set up and make changes to your site’s source code using Fork, a fast, friendly, and open-source git client for Mac and Windows, which you can download here .
After installing the app, you will be asked to configure the User Name and the email that will be associated with your commits, as well as the Default source folder, which is the default folder where the repositories you clone will be stored.
Clone your repository
Each site hosted by Presslabs has a git repository associated with it, containing your site’s source code, along with all the changes that have been made along the way. For more details, check our git specifications .
Additionally, we offer free development sites for development, so you should have at least one development site. This can be set up in two ways, so please check out our Development guidelines for insights regarding your development life cycle, depending on your development site setup.
Make sure to make your changes on your development site first, and only after proper testing push them on the production one. So start up by cloning your development repository.
To clone your repository locally, go to File -> Clone, which will open the following window:
Here, you need to introduce your repository URL, which you can get both from our Dashboard and our Gitea interface, check our Access section .
We recommend cloning your repository using the HTTPS URL and your Managed Hosting Dashboard credentials. The alternative is to set up your SSH keys and clone your repository using the SSH URL.
Your HTTPS repository URL should be something like:
The Name of your local repository should be the name of your instance, e.g mysite-dev. This is not a requirement, but it’s a good practice.
Press Clone, enter your Managed Hosting Dashboard credentials, and your repository will appear in the Fork interface:
In Fork, you can have multiple repositories opened in different tabs, which allows you to quickly navigate to your repositories and organise your workflow efficiently.
How to commit and push changes
A commit records the changes to your repository (site’s source code) that were made to a file or directory. You can see in the Fork interface all the commits that have been made. The next steps show you how to make commits that have some changes in your source code and ultimately push them to your development site or production site.
Step 1: Create a development branch
The commits are stored on a branch, in this case in the default master branch. A branch is essentially an independent line of development. Creating a new branch allows you to work on new features or bug fixes in an isolated environment.
You can easily create a new branch by right-clicking the Branches section -> Create e new branch, which will automatically take you to that new created branch. You can easily switch branches by double-clicking them.
I have created a development branch named development:
Step 2: Make commits with your changes on the development branch
Let’s say you want to add a robots.txt file, which is of great importance for search engines such as Google to index the web content of your site.
First, open your repository in your favourite text editor (e.g.
) and add the robots.txt file in the
Now if you go back to the Fork interface, on the Changes section, you will see the newly added file.
Fork shows you all the files you have modified and not committed yet. The green lines show the lines you have added, whereas the red lines show you which lines you have removed. Now you have to stage these changes, by pushing the Stage button. This adds your modified files to the queue to be committed later.
The next step is to commit these changes.
When committing your changes, you are required to enter a commit message. The commit message provides comments regarding the changes you have made, so they should be as descriptive and easy to understand as possible. Press the Commit button and your changes will appear in the All commits category.
Let’s make some more changes. Let’s add some image thumbnails in the functions.php file of our theme, then stage and commit them.
Now let’s say you want to modify an image thumbnail, I’ll replace the large thumbnail with a small one. The modified lines are intuitively displayed in the Fork interface.
You can visualise all these changes in the All commits section:
Step 3: Merge your development branch in the master branch
After you finish developing your new feature or bug fixing, you need to merge these changes in your master branch.
First, you need to go to your master branch and make sure you have all the modifications from the remote repository. To to this, press the Pull button, which applies the latest changes from a remote repository onto your local repository:
Then right-click the development branch and choose the Merge option.
If there are no conflicts, your branch will be merged, and now your Master branch incorporates the changes too.
Step 4: Push your changes to the remote repository (origin/master branch)
A push updates remote references along with associated objects.
The origin/master branch is the remote repository and it still points to the code from the server. So, the last step would be to push the changes to your remote repository (development site or production one).
First, make sure you are on the Master branch. To push the changes you can either use the Push button, or right-click on the master branch and choose the Push option.
After pushing the changes to the remote repository, you can view them in our Gitea interface at git.presslabs.net or in your wp-admin in the Gitum plugin.
Revert a commit
You can revert a commit by right-clicking in the Fork interface and choosing the Revert option. This will create a new commit that will undo the changes from the commit you want to revert.
When working locally, the Fork interface also provides advanced options of rewriting the history of git commits like interactive rebasing and the reset option. But the Golden Rule of git is to not make such operations on the code that is public, so you may only perform such operations on your local code, before pushing it to the remote repository, for a more readable git history.
If you do however try these operations on production, our Gitium plugin will simply push back the commits that you try to “vanish”, so the only way to undo a commit that is on production is to revert it.
How to handle conflicts when merging the development branch
While merging your development branch into the master one, the first step is to make a Git Pull, which applies the latest changes from your remote repository (development one or production) to your local repository. This means that while you were developing locally, someone else might have made changes that you have also made.
Let’s take an example. Let’s say you want to add a sitemap to your robots.txt file.
You stage and commit your changes, and then you want to merge your developer branch into the master one as shown above.
You need to go on the master branch, Pull your changes, and now your git history looks like this:
On your developer branch you have added a sitemap, reverted the commit, then added the correct sitemap. But someone also added a sitemap on the remote repository, which is now on your local master branch.
When trying to merge, you get a message saying that “The merge will require manual conflicts resolution”. Now you can Cancel the Merge, or continue it and fix the conflicts.
If you choose to continue the merge, go to the Changes section, to see what are the conflicts you need to solve.
In Fork you can resolve your merge-conflicts easily using the merge-conflict helper and built-in merge-conflict resolver. Pressing the Merge in Fork button will open a new window showing you exactly the conflicted files. You can select what changes you want to keep and press the Resolve button and the Fork merge-conflict resolver will take care of the rest.
However, sometimes it is not all black and white and you do not want to keep only your changes or the ones that were made on the remote repository, but to combine them. In this case, instead of selecting one change or the other, go to your conflicted file in your text editor, in this case it’s the robots.txt file:
Here you will see that the conflicted lines are marked down like this:
User-Agent: * Allow: /wp-content/uploads/ Disallow: /wp-content/plugins Disallow: /readme.html <<<<<<< HEAD Sitemap: https://www.mysite.com/sitemap.xml ======= Sitemap: https://www.mySiteIsAwesome.com/sitemap.xml >>>>>>> development
The lines between the
<<<<<<< HEAD section and the separating
======= are the code from the master branch, and the ones below are from your development branch. You can now combine the code as you see fit and make sure to remove the conflict separators:
User-Agent: * Allow: /wp-content/uploads/ Disallow: /wp-content/plugins Disallow: /readme.html Sitemap: https://www.mySiteIsAwesome.com/sitemap.xml
Now, you need to commit the changes you have chosen, and the merge will be successful.
