Psalm Requires PHP >= 7.0 and [Composer](https://getcomposer.org/).

|
|
|
|
|
|
|
|
```bash
|
2018-04-15 16:56:43 +02:00
|
|
|
composer require --dev vimeo/psalm
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Add a `psalm.xml` config:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
./vendor/bin/psalm --init [source_directory=src] [config_level=3]
|
|
|
|
|
```
|
|
|

|
|
where `config_level` represents how strict you want Psalm to be. `1` is the strictest, `8` is the most lenient.
