PRs are welcome, will gladly help with any questions you may have, but pls try to avoid unnecessary refactoring and features that may cause considerable performance degradation, as such PRs won't be accepted. If in doubt, create an issue to discuss whether feature will be acceptable before starting investing into the solution.

If you need help with building the project or understanding the code, feel free to drop at https://t.me/klesun_productions, we can chat there ;)

Autocomplete keys of associative arrays defined in other functions.

Jetbrains Repository: 9927-deep-assoc-completion

Features description

(a bit more relaxed usage guide can be found here)

• Completion from expression

  When you are going to type an associative key of a variable, like in $user[''], put caret between quotes and press ctrl + space. The plugin will analyze your code, determine what keys does $user have and suggest completion.

• Go To Definition

  

  To go to the key definition, hover on it and press ctrl + click or put carret on it and press ctrl + b.

• Completion from phpdoc

  See formats description

  

  You can specify function argument type using @param SomeType $varName = Some::phpExpression(), like @param $anime = ['genre' => 'shounen', 'studio' => 'Shaft']. = is mandatory and expression must be a valid php expression. Class methods can be specified either with complete namespace like \Very\Long\Namespace\ClassName::funcName(), or with just ClassName::funcName().

  You can specify @return array keys as well:

  /**
   * @return array [
   *     'success' => true,
   *     'formObject' => new Form,
   *     'errors' => [],
   * ]
   */
  public static function processForm($arr);

  

• Object type info in an associative array

  

  Phpstorm does not give you method name completion when object is located in an associative array? Don't be sad, this plugin is exactly what you need!

• To N-th Test

  

  Did you ever want an ability to find out which exactly test case does phpunit mean by the with data set "17" without manually counting them? You can find this feature in Tools -> deep-assoc-completion -> To N-th Test. It moves your caret to the test case with the order you specify in the popup. If there are multiple @dataProvider functions in the file, the function caret is currently in will be used. This action will work correctly only on more or less straightforward @dataProvider-s.

• String value completion

  

  

• Transpile to JS code (not related to completion anyhow, but whatever)

  

Completion sources

• Argument type resolution based on what was passed to the function

  

  

  Extremely useful for small private helper functions - you don't need to document args in each of them to get completion.

• Keys from PDOStatement::fetch() if your Database is connected to IDEA

  

• All built-in array functions I could find are supported

  

  

Steps to compile plugin into a .jar follow:

• Start creating a new project in Intelliji Idea.
• Select Intelliji Platform Plugin.
• Select a phpstorm or IDEA Ultimate installation directory as Project SDK (java version is 8).
• Select deep-assoc-completion project folder as Project location.
• In Project Structure -> Libraries add php/lib/php.jar, php/lib/php-openapi.jar and twig/lib/twig.jar from YourPhpStormDirectory/plugins/[php|twig] (in case of IDEA Ultimate, the php and twig plugins should be installed, and the location is HomeOrMyDocumentsDir/.IntellijIdea20XX.X/config/plugins/[php|twig]/lib).
• In Project Structure -> Modules -> Dependencies set Scope of php, php-openapi and twig to Provided.

To build a jar use Build -> Prepare Plugin ... For Deployment. To debug use Run -> Debug. Since phpstorm project takes about a minute to start, you must find Run -> Reload Changed Classes very useful for micro changes.

To use compiled .jar in your phpstorm go to Settings -> Plugins -> Install plugin from disk and select the .jar we compiled earlier.

Shutout my thanks to the JetBrains for continuously supplying me an open source IDE license for this plugin development.
