rector/packages/DeprecationExtractor

Deprecation Extractor

This package extracts 2 cases:

• @deprecate annotation
• trigger_error(*, E_USER_DEPRECATED) from the code.

It helps to generated automate rectors and identify BC changes purely from the code.

How it works?

1. Just read the message
2. Detect what code should be change into what code
3. Create rectors that will do the work

How it helps you?

Instead of using your eyes and brain to read CHANGELOG.md or UPGRADE-x.md, just run it over directory of framework you use:

vendor/bin/rector extract-deprecations vendor/nette

It will show you what changed and how.

Moreover, it will change the code for you.
