Tired of manually fixing PHPStan "errors"?

With CancerStan you can fix some of them automatically or build new fixers yourself to fix even more.

-------

[](#install)

`composer require --dev tetreum/cancerstan`

Usage
-----

[](#usage)

`vendor/bin/cancerstan --dry-run`

CancerStan will run PHPStan first to gather the error list and then try to fix them for you.

Options
-------

[](#options)

- `--dry-run`: Will return the changes to apply without applying them
- `--stan`: To provide PHPStan's location. Ex: --stan=/docker/phpstan . Default: /vendor/bin/phpstan
- `--custom-fixers`: Path to custom fixers directory. Ex: --custom-fixers=./MyCustomFixers

Custom fixers
-------------

[](#custom-fixers)

Your codebase may have it's own tricks and requirements, so you can also make and load custom fixers. Check the `src/Fixers` folder to get an idea on how to build them.

To load them just point CancerStan to their folder like: `vendor/bin/cancerstan --custom-fixers=YOUR_FIXERS_FOLDER_PATH`
