Some smart people told me once, that knowing your tools well is one of the best ways to keep productive and focus on what really matters - delivering value to your customers. Craftsmen are successful only when they know how to use their tools. But do we? Do we know their true potential? How many times did you just blindly added
I’m working at a company which has multiple GIT repositories and I see how developers spend hours configuring their PhpStorm, or just using defaults and wasting time fixing simple mistakes reported in a code review, which could’ve been fixed automatically. It made me wonder how can my tool help me? I’ve been using PhpStorm since the beginning of time, and the official JetBrains documentation recommends adding
.idea folder into VCS, but adding it without understanding implications seemed odd. So I’ve set out to research and experiment with it, see what each of the files does and how can it benefit me and my teammates. Here’s what I’ve found!
I feel these are the main benefits of versioning PhpStorm configuration:
- Increase the productivity of all your teams
- Save time in PRs by focusing only on important bits
- Be easily informed of updated code guidelines
- Bring more clarity to difficult projects using scopes
- Mark directories as a specific type
- Save time for new joiners
- Set up new tools only once
- Allow different projects with unique configurations
If any of these looks interesting for you, read on! Not using PhpStorm? Maybe your IDE has similar ways of sharing configuration?
You won’t be frustrated and will save brain power when working together with your peers because you will have the same IDE setup! When pairing with fellow developers, I have a problem, that our PhpStorm inspection settings are different. For example, they have default inspections enabled, which are not customised for the given project but I have it otherwise, changed a few things so I can safely rely on PhpStorm showing no problem markers in my window. When I see yellow - it makes it hard to focus on what design problem are we solving, instead - I’m looking what are the mistakes the code. It would be solved by having the same set-up.
The example above provides the difference between a file with problems and without. Which one would you prefer to see in your IDE?
Additionally, you can always rely on PhpStorm’s “Perform code analysis” check before commit - it will warn if any of the files included in the commit have problems found by inspections, allowing you to safely fix them before. It’s a possibility to even fix them automatically! I like this feature, because it acts as a double-check for every commit I make, saving me the time to get back and fix my mistakes, or worse - let the SAT (Static Analysis Tool) or any other CI checks to find it 😓. It just makes everything faster.
And finally, there will be an understanding that everyone sees their IDE in the same way, thus no need to double-check for problems or issues that your IDE can detect automatically for you, leaving that precious brain power for more interesting problems!
When reviewing a pull request, I’ve caught myself multiple times writing comments like “please make this compatible with our code style guidelines”, “this is not PSR4 compatible” or “you don’t need this closing tag here”, together with more important comments about design choices or bugs. This always felt like a waste of time and my brain power. Most of these cases can be caught automatically if you share a good PhpStorm set-up together. They will be caught by your CI tool or automated SAT too, but that involves waiting and feels unproductive. You can ask others to update their configuration, but if you work with 50 developers around you, everyone will start asking everyone? That would feel like a waste of time.
You can utilise the powerful inspections engine in PhpStorm, which can be customised and set to have different profiles. For example, you can enable “PHP Code Sniffer” inspection with your custom ruleset, and it will mark only important bits that you care about in the problem sidebar of PhpStorm. You can go as detailed as writing custom regexp rules for all your naming schemes in the code. There is a ton of inspections, and you can add more by using plugins like Php Inspections (EA Extended), all of which can be turned on/off, be set to different reporting level or even scoped to be checkded in one place and skipped in another.
Things change constantly in our world. Say you need to upgrade from PHP 5.6 to PHP 7.0, which comes with new features and removes some old ones. Of course, your agreement on code style and coding standards will change with this too. Now we all know people don’t like change and it’s very hard to remember these things, especially when you’re coding for a long time in an old convention, but if your configuration is shared between all of your developers, this would be avoided!
By versioning your PhpStorm’s settings, you can just enable any new inspections for those new features and commit it, and everyone eventually will have them. Do you have a code style change too? Maybe some new plugin settings were added? Commit them too! This saves you from adding additional documentation somewhere else (we know it gets outdated very fast), gathering everyone in a meeting to announce these changes or sending mass emails which no one reads. This change will be always in your Git history, and as long as you have clear commit messages, that can serve as your documentation and reasoning for the change. If there is an opinionated change - pull request can be a place where everyone can have a discussion, the same place, where you’re discussing code too.
Note 1 - unfortunately currently there is no possibility to share installed plugins via
.idea folder and has to be done by each developer separately, the good news is that you can version configuration of those plugins regardless if it’s installed in PhpStorm or not.
Note 2 - Only the inspections that are “Stored in Project” are saved in
.idea and can be shared.
If you work on a big project - most likely you will have a mix and match of a codebase that has a different levels of quality. Or perhaps you have different rules for your tests? Controllers? Maybe you have a “legacy” folder that contains unmaintainable code and you want to ignore it? Then probably you also don’t want to rely on PhpStorm to check all of your files, since it will report on a lot of problems in those areas which will be only noise, hiding important problems. That kind of beats the purpose of utilising this awesome IDE right?
Did you know that you can create different scopes and then apply different rules to those scopes? You can use scopes in search, inspections with an addition of adding different colours to them! “A scope is a subset of files, and/or directories in your project, to which you can limit the application of specific operations, e.g. search, code inspection, etc.” Read more about scopes at PhpStorm help.
I’m using scopes to help me find my way around the project and set up different inspection settings for them. First, I am using them to add colours to different file types. If you have your filenames formatted like
AddCommentCommand.php or let’s say you keep all of your controllers in the
Controller directory, you can define different colours for them. This helps me very quickly identify what I’m looking for in a big list of files or in the search.
You can see I’ve coloured my Commands in blue and Controllers in red so now I can easily distinguish between them without reading actual names. Their background will be the same in search also.
Another use for scopes is inspections. You can define different levels for inspections (or completely disable them) for different kind of scopes.
Here I disabled the warning for an undefined class constant in my Controllers scope.
This helps me to customise my project setup even further and allow specific checks to be disabled for problematic or opinionated pieces of the code. For example, sometimes my tests don’t have proper references set-up, so I can disable those checks only for tests scope (not that it’s a good practice, but it removes noise from signal). Or I have a very old code stored in a separate directory, I can disable the check for PSR4 class names there because I know, we won’t be changing them anytime soon, so why to train our brain to ignore those warnings? This way it will ignore the important ones too. You can go to any extent you want with this customisation, with the goal being not to miss important bits, remove noisy warnings and have PhpStorm inspections always reporting green 💚.
Note - Don’t forget to create “Shared” scope in order for it to end up in
Have you created a lot of new files using PhpStorm and wondered how could you save time by not retyping the namespace constantly? Well did you know about marking folders as different types? Here’s an excerpt from documentation about Content Roots: “Within a content root, PhpStorm can distinguish between the folders that contain source code, and the ones to be ignored while searching, parsing, watching etc. To do so, you can mark any folder below a content root as a source folder, or as excluded so it becomes invisible for PhpStorm”. This can save a tiny bit of your computer resources and minimise the noise you are seeing when searching or looking up by symbol/filename/class.
If you have composer integration enabled, recent versions of PhpStorm have the ability to mark Source directories automatically by understanding PSR-0 and PSR-4 paths from
composer.json. I find a couple of things very useful for marking directories as source or test. First of all, I can set up proper namespaces for those directories (sometimes in complex projects PhpStorm can’t detect them automatically) which helps me with creating new classes or moving them around - I don’t need to retype them every time. Automation FTW! Additionally, I can set up test directories and have PhpStorm automatically detect where to create a new test (or a new class from a test) when navigating to test/to class. I spend less time navigating in my directory tree and just jump forward/ backwards between a test and the implementation.
You can see here how my
src directory has a
Donis\Phwitch namespace set by default, also PhpStorm ignoring all of the composer dependencies, because they are added in the include path.
It’s your first day on a job, you got your fresh Macbook out of the box, the credentials in your email and you’re ready to go. Wouldn’t it be awesome if you could submit your first PR by the end of the day and deploy it to production instead of spending that day customising your PhpStorm? I would love this! This could be true if you share your PhpStorm configuration with everyone and commit that
.idea directory into VCS. As a newly joined developer, I would love to have necessary inspections set up for different projects, so I can refer to them (which is few keystrokes away) instead of trying to find that documentation link someone mentioned somewhere in a Slack channel and also added that it might be outdated. How terrible is that? And what if that company has more than one repository with different level of codebases you’ll have to work on? That would save days of configuration tinkering, not to mention you’d have to do this all again after your MacBook would break down.
Let me give you a different example - you work in a place where you work not only with PHP but also with Node.js, tiny bits of Python and JS for your UI. Those different codebases have different rules and styles to follow. How can you make sure, that you commit and ask to review only the code that follows the rules of that project? For me, the fastest way would be to receive that feedback right inside my PhpStorm (WebStorm or PyCharm) window instead of humans finding them in a PR I submitted.
Another addition to your shared configuration might be File and Code Templates. These allow customising how newly created files, code snippets or parts of files look like. For example, don’t like the default comment PhpStorm adds when creating a new PHP file? Just remove it from “Project” scheme and everyone in the future will save a second or two by not constantly removing it. Do you have a specific type of controller that extends or implements something special? Create it as a template, share it and new joiners won’t have to learn by heart how to create it, they can just “Create a new controller” in PhpStorm and be done with it. Every bit that can be automated for newly joined people will help them focus on learning your domain and business instead of learning your toolset.
Do you have a custom deployment to the remote server or something similar? This can be also shared with everyone because it will end up in
If you share PhpStorm configuration, only one developer has to add a new tool configuration into their PhpStorm. Let’s say you have added Behat setup to your project. PhpStorm has a very nice integration with it and you can set up one or more run configurations to easily run all your Behat tests from within PhpStorm. PHPSpec? Jest? Docker? Any of these tools have some kind of configuration, which, if needed, can be customised to suit your needs. I am assuming, you want all of your fellow developers to have the benefit from these new tools and save their time and fuss when setting them up? Imagine the disaster when someone will misconfigure PHPUnit and skip running half of the tests!
Run Configuration of all of these tools can be shared with your
Note 1 - When creating “Run Configuration” don’t forget to mark “Shared” checkbox, otherwise it won’t end up in
Note 2 - If you use a lot of external tools, this might not help you, looks like they can’t be shared between projects.
If you’re working on multiple projects - I guess not all of them are equal. Perhaps one is written in some old custom framework, another one is using Symfony 4? For sure they will need different inspections, run different tools and have different scopes. If you have your PhpStorm configured to your liking or generic company guidelines, the amount of noise and frustration will soon teach your brain to ignore all the warnings and notices PhpStorm is reporting to you, since both of those projects can’t fit into just one configuration. Blindly ignoring problems reported from PhpStorm is probably one of worst things that can happen to a developer Why are you paying for the tool and ignoring it then? Those problems will be caught, but by a human instead of a machine, which in my opinion is much more costly.
.idea directory with customised configuration for each project, you’ll keep following the guidelines specific to that project, not necessarily only the generic ones. At the same time, it gives some room for experimentation of new or different tools in smaller projects, perhaps a different code style standard, different testing framework. And flexibility is the key, right? You will also be able to easily contribute to projects of other teams without learning how their project is set up, you’ll receive all the needed feedback from within PhpStorm.
This will exclude sensitive information like data source info (database connections), user-specific files, like workspace setup, tasks, and dictionaries (if you do have specific dictionaries for your project, definitely add them!). Also, some plugin settings, build outputs and others that are deemed not needed to be shared with the project.
If you have a larger group - start by discussing how PhpStorm can help you guys in your situation. Code style? Default inspections? Maybe just scopes? Pick a few volounteers and let them checkout a branch with
.idea commited inside, see how they transition or if they have any feedback.
If you see that some of your configuration settings didn’t end up inside of
.idea folder - make sure you have created a “Shared” setting! Sometimes these are easily missed. Also, they have a different name in some cases (code style, inspections) and they should be set to “Stored in Project”. Settings which are marked “For current project” will also end up inside of
PhpStorm takes time to show you the changes inside of
.idea folder inside of “Version control” window. You might want to click “Refresh VCS changes” to update the list and you’ll see the updated files.
Some of the files are updated quite often. In PhpStorm’s case -
php.xml are the most ones updated because they contain the list of all composer dependencies (since they’re added as libraries by default). They are either forgotten to commit (didn’t see the change) or are outdated if a developer forgot to run
composer install. This might be fixed in the future PhpStorm versions, but keep an eye on that, especially when composer packages have changed.
Not completely all of the settings can be shared. For example - user created live templates can’t be shared (must be deemed too personal).
PhpStorm is a beast 🐻! It has so much functionality, but sometimes we use it only as a text editor, not an IDE. I hope you are going to start sharing your PhpStorm configuration with everyone inside your company/team too! Please let me know in the comments below if you’ve learned something new from this or if I can update this article in any way or if you have just any feedback.
In the next post related to PhpStorm, I will dive deeper into some of the files that are contained inside of shared
.idea directory and explain what they’re responsible for, so you can fine-tune your setup of what are you adding into VCS and what not. Thanks for reading & happy coding!
