Current Vim setup for PHP development

published on February 10, 2017.

I made some changes to my Vim setup for PHP development recently, so it’s time to write it all down. I’m more than sure that I’ll break it soon and won’t be able to remember all the things I did to have the current setup.

Some new plugins popped up on my radar, I tweaked some older plugins and I even wrote one for PHPStan!

Last year I wrote how I got really good tag support in Vim, so I’ll first expand on that.

Gutentags

Gutentags is probably the plugin that had the biggest impact on my workflow. It made possible many other functionalities and plugins to just work.

First thing I have configured for it is the location for the tag files:

" Where to store tag files
let g:gutentags_cache_dir = '~/.vim/gutentags'

The second is a more “aggressive” excluding of files from generating tags:

let g:gutentags_exclude = ['*.css', '*.html', '*.js', '*.json', '*.xml',
                            \ '*.phar', '*.ini', '*.rst', '*.md',
                            \ '*vendor/*/test*', '*vendor/*/Test*',
                            \ '*vendor/*/fixture*', '*vendor/*/Fixture*',
                            \ '*var/cache*', '*var/log*']

Takes out a lot of rubbish.

I also have the following in the global ~/.ctags configuration file (gutentags uses ctags under the hood to generate the tags):

--PHP-kinds=+cfit-va

This way I get tags for classes, interfaces, functions, namespaces and traits, while variables and aliases are ignored to remove the noise level.

Jump to definition

I paired CtrlP’s CtrlPTag method with gutentags tag files to get jump to definition functionality:

map <silent> <leader>jd :CtrlPTag<cr><C-\>w

My complete CtrlP settings are here.

Current PHP class and method

A combination of three Vim plugins and a PHP phar file gives me the possibility to show in the status bar the current PHP class and method.

Lightline provides the status bar, tagbar to get the current tag, tagbar-phpctags to generate the tags for the current file using phpctags.

Use the following setting to tell tagbar about the phpctags binary:

let g:tagbar_phpctags_bin='~/.vim/phpctags'

This is the tagbar line for lightline:

'tagbar': '%{tagbar#currenttag("[%s]", "", "f")}',

See here how it all fits together.

Now that I wrote it all down, I should take a look if I could use the gutentags tag files for this. Seems like an awful lot of moving parts for a relatively small feature.

PHP namespaces

The vim-php-namespace plugin provides support for inserting use statements in PHP code. It will use the tag files generated by gutentags, there’s no need to set up anything for that.

I have the following mapping to insert the use statements:

function! IPhpInsertUse()
    call PhpInsertUse()
    call feedkeys('a',  'n')
endfunction
autocmd FileType php inoremap <Leader>pnu <Esc>:call IPhpInsertUse()<CR>
autocmd FileType php noremap <Leader>pnu :call PhpInsertUse()<CR>

and this one for expanding classes to get their fully qualified names:

function! IPhpExpandClass()
    call PhpExpandClass()
    call feedkeys('a', 'n')
endfunction
autocmd FileType php inoremap <Leader>pne <Esc>:call IPhpExpandClass()<CR>
autocmd FileType php noremap <Leader>pne :call PhpExpandClass()<CR>

I also let it to automatically sort the namespaces after inserting:

let g:php_namespace_sort_after_insert=1

Linting

ALE is an Asynchronous Lint Engine and it provides linting for Vim 8. It can do linting for a bunch of languages.

My configuration for it is:

let g:ale_linters = {
\   'php': ['php'],
\}
let g:ale_lint_on_save = 1
let g:ale_lint_on_text_changed = 0

Lints PHP files on save, in the background. A must have!

A promising completion engine for PHP

php.cd finally provides useful completion for PHP. It’s still rough around the edges, misses a feature or two, but I find it a lot better than any other completion engine I used before. No need to configure anything for it, just follow their installation instructions and that’s it. ^X^O all the things!

PHPStan in Vim

PHPStan is a static analysis tool for PHP and I wrote a small plugin for it, vim-phpstan. It calls phpstan from Vim and populates Vim’s quickfix list with the errors.

For now, the only possible configuration is to set the analyse level:

let g:phpstan_analyse_level = 2

Debugging

Sadly, there is no good PHP debugging client for Vim. Or none that I know of. There are a couple of them out there, but they seem long abandoned. I work on a standalone PHP debugging client, pugdebug, but it has it’s own set of problems as well (packaging on Linux is a nightmare).

Supporting plugins

Other “supporting” plugins are 2072/PHP-Indenting-for-VIm, 2072/vim-syntax-for-PHP, sirver/ultisnips, plugins from the sniphpets organization, ddrscott/vim-side-search, robertbasic/vim-argument-swapper.

I’m pretty happy with the current setup. Do you know maybe of any interesting plugin I’m missing? Let me know!

Happy hackin’!

Events in a Zend Expressive application

published on August 04, 2016.
Heads-up! You're reading an old post and the information in it is quite probably outdated.

Three weeks ago I wrote a post on how to utilize Tactician in a Zend Expressive application. Today I want to expand on that post a little by adding the possibility to trigger and listen to events using the Zend EventManager component.

Using events allows our application to respond to different events that occur during a request. For example, when a user registers a new account, our application can trigger an event, UserRegistered, that can let the rest of our application know when a new registration happens. With the help of the EventManager we attach listeners to that event. When the UserRegistered event is triggered, the event manager will invoke all the listeners that are listening to that particular event.

This allows for a better separation of concerns in some cases, because if we take this approach, our code that deals with registering new users doesn’t care any more what happens after that — do we send out a welcoming email to the user, a notification to the site admins, create a log entry somewhere… It just registers a new account, triggers the event and that’s it.

Let’s see some code

As I mentioned earlier, this post expands on my previous post, so all we are going to add is an event that gets triggered when the Ping command is handled, an event listener that listens to that event and wire it all together with the event manager.

Let’s include the Zend EventManager in our project with composer:

$ composer require zendframework/zend-eventmanager

Next we expand the factory for the Ping command handler. We create an EventManager object that we will pass to the Ping command handler, so that we can trigger events:

src/App/CommandHandler/PingFactory.php

diff --git a/src/App/CommandHandler/PingFactory.php b/src/App/CommandHandler/PingFactory.php

+        ]);
+
+        return new Ping($logPath, $events);
     }
}

Later on we will use the same event manager to attach event listeners to our events.

In the Ping command handler we use the event manager, that we pass in as a constructor argument from the ping command handler factory, to trigger events:

     }
}

The main part is the call to the trigger method on the event manager. The first argument, ping_command_handled, is the event’s name. We will use that event name to attach to it later. The second argument is the target of the event and usually it’s the object instance that triggers the event. Finally with the third argument we can send out optional parameters with the event which we can access in our event listeners.

Even though we have no listeners attached to the event, our application will continue to work perfectly fine, because an event is not required to have any listeners. It doesn’t make much sense to have events without listeners, but it wouldn’t break our application.

Shhh… Listen!

The simplest way to attach a listener to the event would be to tell the event manager to call a callable every time the event is triggered. This would also mean we need to set up any and all dependencies our event listeners have, at the moment of attaching the listener to the event, even though the event can end up not being triggered at all. All that dependency set up can be costly and wasteful.

Zend EventManager comes with lazy listeners that allows to fetch event listeners from a container-interop compatible container. This lets us to set up the dependency graph for an event listener in a factory, which will be invoked by the lazy listener only when the event we are listening to is triggered. If the event is triggered, the lazy listener will fetch the event listener from the container along with it’s dependencies, but if the event is not triggered, nothing will happen. Super useful!

Let’s attach our event listener to the event using the lazy listener:

src/App/CommandHandler/PingFactory.php

+
+        $events->attach('ping_command_handled', $lazyListener);
+
         return new Ping($logPath, $events);
     }
}

We create a new LazyListener object and as the first argument to it we pass an array with the actual event listener and method that will be called when the event is triggered. The second argument is the container-interop compatible container, which knows how to build our event listener.

After that we attach the lazy listener to the events we are interested in, in this case the event called ping_command_handled. Once that event gets triggered, the lazy listener will get our PingEventListener from the container and call the onPingCommandHandled method on it.

Let’s quickly tell the container how to create our event listener:

+            App\EventListener\Ping::class => App\EventListener\Ping::class,
         ],
     ],

And finally our event listener looks something like this:

src/App/EventListener/Ping.php

<?php
namespace App\EventListener;
use Interop\Container\ContainerInterface;
use Zend\EventManager\Event;
class Ping
{
    public function __invoke(ContainerInterface $container)
    {
        // Grab some dependencies from the $container
        // And return self
        return new self();
    }

    public function onPingCommandHandled(Event $event)
    {
        // Do something with the $event here
        $name = $event->getName();
        $target = $event->getTarget();
        $params = $event->getParams();
    }
}

When the container grabs our event listener the __invoke method will be invoked at which point we can grab the event listener’s dependencies from the container. Once the event listener object is created, the onPingCommandHandled method will be called by the event manager when the event is triggered.

Missing colors for PHPUnit

published on July 20, 2016.
Heads-up! You're reading an old post and the information in it is quite probably outdated.

I ran accross a minor issue today that I never experienced before. The colors for the PHPUnit’s output were missing. I had the colors=true directive set in the phpunit.xml configuration file, but the output was just black and white.

Turns out I was missing the posix extension, which is provided by the php-process package on Fedora. After installing it:

$ sudo dnf install php-process

all was good again in the world of unit testing.

Oh well.

Happy hackin’!

Using Tactician in a Zend Expressive application

published on July 13, 2016.
Heads-up! You're reading an old post and the information in it is quite probably outdated.

I spent some time connecting the dots last week, so I decided to put together an example on how to get started with using Tactician in a Zend Expressive application. The example itself is not really useful, but it does show how to setup the dependencies and get started with these two libraries.

Zend Expressive is a PSR7 compatible microframework that provides interfaces for routing, DI containers, templating and error handling. It provides a couple out of the box, so you can either use those, or write your own implementations.

Tactician is a command bus library whose goal is to make using the command pattern easy to use in your applications. It allows to have an object that represents a command, pass it on to the command bus which will figure out which command handler should take care of that command.

Let’s dive in

To get up and running quickly with Zend Expressive we can create a skeleton application. It does some basic wiring for us, like setting up the routing and the DI container.

It also comes with a dummy ping action, at /api/ping, which just gives us the current unix timestamp. This example is going to expand on that and create a Ping command that will be handled by a Ping command handler. The command handler will get some additional dependencies from the container, just to make the example a bit more interesting.

Creating the skeleton application is really easy with Composer:

$ cd /var/www
$ composer create-project zendframework/zend-expressive-skeleton tactician-example

Bring in the Tactician and the tactician-container plugin as project dependencies. The tactician-container plugin allows us to lazy load command handlers from a container-interop compatible container:

$ composer require league/tactician
$ composer require league/tactician-container

Now that we have all our libraries in, let’s change how the container creates the Ping action. Before it was being just invoked by the container, but now we want to create it through a factory:

config/autoload/routes.global.php

+            App\Action\PingAction::class => App\Action\PingFactory::class
         ],
     ],

This will allow us to pass in dependencies to the PingAction class.

The Ping action’s factory is simple:

src/App/Action/PingFactory.php

<?php

namespace App\Action;

use Interop\Container\ContainerInterface;

class PingFactory
{
    public function __invoke(ContainerInterface $container)
    {
        $commandBus = $container->get('CommandBus');

        return new PingAction($commandBus);
    }
}

We are telling the container to get the service called CommandBus and pass it as an argument to the Ping action’s constructor.

Wiring in Tactician

We haven’t yet defined the CommandBus service, so let’s do that next by telling the service manager to create the CommandBus using the App\CommandBusFactory factory:

config/autoload/dependencies.global.php

diff --git a/config/autoload/dependencies.global.php b/config/autoload/dependencies.global.php

+            'CommandBus' => App\CommandBusFactory::class
         ],
     ],
 ];

This factory sets up the Tactician’s command bus and is the main point of this example:

src/App/CommandBusFactory.php

<?php

namespace App;

use League\Tactician\CommandBus;
use League\Tactician\Handler\CommandHandlerMiddleware;
use League\Tactician\Container\ContainerLocator;
use League\Tactician\Handler\CommandNameExtractor\ClassNameExtractor;
use League\Tactician\Handler\MethodNameInflector\InvokeInflector;
use Interop\Container\ContainerInterface;

class CommandBusFactory
{
    public function __invoke(ContainerInterface $container)
    {
        $inflector = new InvokeInflector();

        $commandsMapping = [];
        $locator = new ContainerLocator($container, $commandsMapping);

        $nameExtractor = new ClassNameExtractor();

        $commandHandlerMiddleware = new CommandHandlerMiddleware(
            $nameExtractor,
            $locator,
            $inflector
        );

        $commandBus = new CommandBus([
            $commandHandlerMiddleware
        ]);

        return $commandBus;
    }
}

Tactician uses a command handler middleware to handle commands. That middleware in turn uses a name extractor to get the command name out of a command, a locator to find the actual command handler and an inflector to figure out the method to call on the command handler to handle the command. Tactician’s middleware system is nicely described in the documentation.

The ClassNameExtractor will extract the command name from the class name.

The ContainerLocator will use our container-interop compatible container to find the command handler, which in this example is Zend ServiceManager.

The InvokeInflector dictates that the command handler needs to have an __invoke method which will get our Ping command as an argument and then it’s up to the Ping command handler to handle the command.

The $commandsMapping array that we are passing to the locator is going to be a map of commands and their handlers. We’ll populate that later on.

In the next step, let’s tell the PingAction’s constructor to accept the command bus:

src/App/Action/PingAction.php

diff --git a/src/App/Action/PingAction.php b/src/App/Action/PingAction.php

Cool, at this point we have everything set up to start sending and handling commands.

Commands and their handlers

The command we are going to create is a simple one:

src/App/Command/Ping.php

<?php

namespace App\Command;

class Ping
{
    private $commandTime;

    public function __construct()
    {
        $this->commandTime = time();
    }

    public function getCommandTime()
    {
        return $this->commandTime;
    }
}

It just sets the command time to the current unix timestamp.

         $nameExtractor = new ClassNameExtractor();

We’re almost there. I promise.

The command handler is going to be created through a factory, so we can inject dependencies into it:

src/App/CommandHandler/PingFactory.php

<?php

namespace App\CommandHandler;

use Interop\Container\ContainerInterface;

class PingFactory
{
    public function __invoke(ContainerInterface $container)
    {
        $logPath = '/tmp/ping-command.log';

        return new Ping($logPath);
    }
}

It doesn’t do much, it just passes a path to a log file. Of course, in real code, you’d probably pass in some dependency gotten from the container.

The command handler won’t do much either, it’s just going to log the the ping’s command time in the log file we passed in from the command handler factory:

src/App/CommandHandler/Ping.php

<?php

namespace App\CommandHandler;

use App\Command\Ping as PingCommand;

class Ping
{
    private $logPath;

    public function __construct($logPath)
    {

    }

        $commandTime = $pingCommand->getCommandTime();

        file_put_contents($this->logPath, $commandTime . PHP_EOL, FILE_APPEND);
    }
}

And finally let the service manager know how to create the Ping command handler:

 ];

Navigating to /api/ping should display the {“ack”:1468171544} response, and the log file at /tmp/ping-command.log should have the same timestamp logged.

That was a lot of code

I know, looks like an awful lot of code just to log a timestamp in a file somewhere. But the point is that even for more complicated commands and handlers the basic wiring stays the same — create the CommandBus factory, set up mapping of commands and handlers and the rest is pretty much the business logic of the application.

Happy hackin’!

P.S.: I’m trying out this new way of providing code samples by using diffs, so it’s easier to follow what changed where. Let me know how it looks, thanks!

published on March 09, 2016.
Heads-up! You're reading an old post and the information in it is quite probably outdated.

One thing I was missing for a long time in Vim is to be able to “jump to definition” in an easy and painless way.

The other thing I wanted to improve is to be able to tell easily where am I actually in the code base; to see the current class and method name of wherever the cursor was.

With a bit of googling and poking around, I finally came up with a perfect combo of 5 plugins (yep, five!) that enables me to do both, and a little bit of extra.

Tags made easy

Gutentags  is a brilliant Vim plugin that makes it so easy to have tags. Just install the plugin and boom! Tags! It will figure out things on it’s own and just generate the tags in the background. I use it daily for a fairly large code base and I never had any problems with the tags, or with Vim being unresponsive while the tags are being generated.

The only two settings I have set for it is what to exclude and where to store the tag files to not pollute the current project with them.

let g:gutentags_exclude = ['*.css', '*.html', '*.js']
let g:gutentags_cache_dir = '~/.vim/gutentags'

That’s it.

Jump to definition

Pair gutentags with CtrlP and it’s CtrlPTag method and we get jump to definition.

map <silent> <leader>jd :CtrlPTag<cr><c-\>w

Move to the method name we’re interested in, hit <leader>jd and it will jump to it’s definition. Tip: <C->w means “insert word under cursor”.

Where the hell am I?

My second requirement for displaying the current class and method name was a bit more difficult to fulfill. It takes the tagbar, tagbar-phpctags and lightline plugins as well as the phpctags tag generator to accomplish that.

Let the tagbar plugin know where the phpctags bin is:

let g:tagbar_phpctags_bin='~/.vim/phpctags'

This will make the tagbar plugin use phpctags to generate tags for the current file. To finally display the current tag in lightline, I wrote a simple tagbar component for it:

'tagbar': '%{tagbar#currenttag("[%s]", "", "f")}'

My complete lightline settings at the time of writing this can be found here.
