Nicky Robinson 8e77ff1ce9 Throw error if magic getter or setter called for undefined property or invalid type specified with annotations (#500) 
* Fix path to psalm

* If a magic getter or setter is used to access a property on a class
that is not defined but a `@property` annotation for the property
exists, throw an error. If no `@property` annotation exists, it's not
an error because you're allowed to make magic getters and setters do
crazy things.

Fixes #480

* Move logic to a better place to avoid duplicate checks

* Move logic into function

* Remove some nesting

* Check psalm-seal-properties and property type correctly

Psalm is a static analysis tool for finding errors in PHP applications.

  • v0.3.x supports checking PHP 5.4 - 7.1 code, and requires PHP 5.6+ to run.
  • v0.2.x supports checking PHP 5.4 - 7.0 code and requires PHP 5.4+ to run.

Check out the wiki or try a live demo!

Quickstart Guide

Install via Composer:

composer require --dev vimeo/psalm

Add a config:

./vendor/bin/psalm --init

Then run Psalm:

./vendor/bin/psalm

The config created above will show you all issues in your code, but will emit INFO issues (as opposed to ERROR) for certain common trivial code problems. If you want a more lenient config you can specify the level with

./vendor/bin/psalm --init [source_dir] [level]

You can also learn how to suppress certain issues.

How Psalm Works

A basic rundown of Psalm’s internals can be found in docs/how_psalm_works.md.
