CakePHP Tips 2017 Part 1

14 Apr

Whoops as ErrorHandler

I recently switched to Whoops in my apps.
It provides a better exception rendering for development mode for most cases.

Just load the plugin (gourmet/whoops) and modify the bootstrap line:

//(new ErrorHandler(Configure::consume('Error')))->register();
(new \Gourmet\Whoops\Error\WhoopsHandler(Configure::consume('Error')))->register();

If you already have a src/Application.php and run a middleware setup, you also want to make sure you either remove the ErrorHandlerMiddleware there, or provide a custom one for Whoops.

You can test it for example with my sandbox app.
Check it out locally, set it up in minutes and give it a test run.

Jump from browser to IDE

With the Whoops error handler the probably nicest feature is the "click to IDE" one.
The open PR from me enables this.

It allows to click on the class inside the displayed code piece and jump right into the IDE into the exact line of that file displayed in the browser stack trace.

Be more productive leveraging your IDE

Using the new IdeHelper plugin you can now not only bake annotations into new code, but also adjust
your existing code all the time.
The plugin provides a shell to quickly sync the existing annotations with your code.

This way you can maximize IDE compatibility and with that prevent obvious issues and mistakes.
The IDE will usually mark problematic code yellow (missing, wrong method etc).

It can also enable you to click through the classes and object chains which otherwise would just be plain text and have no typehinting.
Finally autocomplete will be available for all the "magically" provided classes and methods this way.

This plugin is supposed to work with ANY IDE that supports annotations.
The plugin wiki contains even details and tips/settings for each of those IDEs – collected by the community.

Enable PHPStan in your app and plugins

PHPStan is a super useful static code analysis tool.
It will help you to find issues with your code way beyond what the test suite or IDE syntax checks can do.

For example, if you have two many different return types and only respect one of them, it will mark this as issue.
It will also tell you about interface mismatch or other similar code smells.

Adjust Travis

Add a new matrix row and a script call for that matrix entry:

...
matrix:
  include:
    ...
    - php: 7.0
      env: PHPSTAN=1 DEFAULT=0
...
script:
  ...
  - if [[ $PHPSTAN == 1 ]]; then composer require --dev phpstan/phpstan && vendor/bin/phpstan analyse -l 1 src; fi
...

Level 1 (-l 1) is the lowest level, once everything passes you can go up to level 5 currently. I recommend trying level 3, if possible.

If you need to ignore certain errors, you can use a custom phpstan.neon file in your /tests directory and then append -c tests/phpstan.neon into the command for travis.

vendor/bin/phpstan analyse -c tests/phpstan.neon -l 1 src

For me such a file looked like this, for example:

parameters:
	autoload_files:
        	- %rootDir%/../../../tests/bootstrap.php
	excludes_analyse:
		- %rootDir%/../../../src/TestSuite/*
	ignoreErrors:
		- '#Call to an undefined method Cake\\Datasource\\EntityInterface\:\:source\(\)#'

Don’t try to ignore too much, though – only "false positives" are recommended to be added here.

You can also write custom PHPStan extensions, see the current CakePHP core /tests/PHPStan folder for details.

Using it locally

I added this to my plugins’s composer.json files:

"scripts": {
    ...,
    "phpstan": "phpstan analyse -l 1 src",
	"phpstan-setup": "cp composer.json composer.backup && composer require --dev phpstan/phpstan && mv composer.backup composer.json"
}

This will allow local testing without messing up your composer file 🙂
For app instead of plugin development you also want to backup-restore the lock file.

Now just run

composer phpstan-setup
composer phpstan

I bet you will find a few useful issues to resolve right on the first run of this tool.

Setting up PHPDesigner for CakePHP

22 Sep

There are many great IDEs for PHP development.
One is PHPDesigner, which is mainly for windows.

With some minor adjustments it works pretty well with cake.

Preferences

Go to: Tools -> Preferences [CTRL + E]

  • General

    • File Encoding: UTF8
    • Trim on save: Trim Right (no need to save empty spaces to the right)
    • Detect Changes: Yes (very useful!)
    • Sublink -> Document Types: Add *.ctp to PHP
  • Editor

    • Tabs: YES (we want to use one tab as indend)
    • Tabs to spaces: NO (should not be converted)
    • Tab Width: 2 (so one tab will be 2 spaces wide)
  • Debugger

    • Syntax Check: I like to use a little bit different color here (a brighter red).

Those are just the most important ones. You can play with other settings, as well.

Project Setup

Go to: Project -> Project Manager [F11]

  • New => Add "Title" => Select "Root Folder" (should be your app directory!)
  • => Add "Libraries" (I usually add the cake folder, but you could also add the vendors folder here)
  • => Just hit "Next" until it’s finished.
  • You can now open the project. After a few seconds/minutes all functions are indexed and can be looked up with "Rightclick -> Go to declaration".

All PHP-internal functions can be looked up with F1 (Quick lookup in the PHP Manual).

To read more about code completion, see my other article about it.
It describes how you can use a shell script to dump all components, helpers, … into one "dummy" file to help PHPDesigner index and auto-complete all library functions.

Here is one example of how all cake and app functions get auto-completed and displayed:

Final Tips

Sometimes the files you open are still ANSI. If you add UTF8-Signs save it as UTF8 in order to display them correctly. Otherwise it will either be nonsense or nothing at all.
After editing or creating Projects you need to properly close and restart your editor. Otherwise changes might be lost after the next restart. This is some bug of PHPEditor, I guess.

PHPDesigner and Linux

The best of all IDEs is nativly only available for Windows.
For all those poor rats out there that use Linux:

Seems to work (if you believe the comments).
