1. TRANSFORMING MAGENTO

2. HI

3. THANKS: NOMADMAGE AND NOMADPHP

4. DISCLAIMER: I'M REALLY NEW

5. DISCLAIMER: HERE BE DRAGONS

6. ! composer require tinify/magento2

7. LOOK AT THESE GETTERS AND SETTERS

8. EVER MISS FEATURES FROM ANOTHER LANGUAGE?

9. TECHNICALLY: MAGIC METHODS

10. IMAGINE WE COULD USE THIS SYNTAX...

11. ALAS, THE TESTS FAIL

12. ! composer require pre/class-accessors

13. WHAT'S THIS, THE TESTS PASS

14. WHAT HAPPENED?

15. WHAT IF WE WANT OUR OWN MAGIC METHODS?

16. YOU HEAR ABOUT THE TRAILING COMMAS PROPOSAL?

17. wiki.php.net/rfc/list-syntax-trailing-commas

18. SIDETRACK: STRANGE INCONSISTENCIES...

19. LET'S TRY

20. ! composer require pre/trailing-commas

21. SOMETHING SERIOUSER

22. HANDS UP IF YOU'VE EVER USED DEPENDENCY INJECTION

23. LOOK AT THAT XML!

24. ! composer require pre/parameter-loaders

25. ! composer require pre/property-loaders

26. CODE YOUR MUM WOULD APPROVE OF

27. SOMETHING SIMPLER

28. EVER OPEN A FILE HANDLE ...OR CREATE A MUTEX LOCK?

29. CAN'T RETURN IMMEDIATELY BECAUSE OF STUPID FILES

30. ! composer require pre/deferred

31. WITH 50% MORE BLOCKS

32. $handle = fopen("path/to/file); defer { fclose($handle); unlink("path/to/file"); } return fgets($handle);

33. HOW DOES THIS WORK?

34. SPOILERS: JUNE 22ND, NOMADPHP

35. PAUL'S [FOURTH] STANDARDS RECOMMENDATION

36. COMPILES: File.pre ! File.php

37. github.com/marcioAlmada/yay

38. WHAT DOES THIS CODE LOOK LIKE?

39. class Sprocket { public $name = new Translatable(static::class); public function

    turn($spanner = factory("spanner")) { return $spanner->use($this); } }

40. class Sprocket { use \Pre\PropertyLoaders\PropertyLoadersTrait; private $name; private function loadNameProperty()

    { $this->name = new Translatable(static::class); } public function turn($spanner = null) { if (is_null($spanner)) { $spanner = factory("spanner"); } return $spanner->use($this); } }

41. ! composer require friendsofphp/php-cs-fixer

42. IS IT SLOW?

43. ! composer du -o

44. ! composer dump-autoload --optimize

45. MAKES A LOCK FILE

46. GREAT FOR DEV GREAT FOR PROD

47. CAN I USE THIS TO MAKE MY OWN SYNTAX?

48. OTHER THINGS: ▸ immutable classes ▸ short arrow functions

49. WHY WOULD I USE THIS?

50. REASONS TO USE: ▸ You like the syntax I've shown

    ▸ You repeat code ▸ You repeat code

51. REASONS TO USE: ▸ New syntax could be clearer and

    more concise ▸ You want features from other languages ▸ You want to support old PHP

52. process .."/helpers.pre";

53. process __DIR__ . "/helpers.pre";

54. \Pre\processAndRequire(__DIR__ . "/helpers.pre");

55. process __DIR__ . "/helpers.pre";

56. process .."/helpers.pre";

57. REASONS NOT TO USE: ▸ No IDE support ▸ You

    have to teach developers new syntax ▸ You have to learn how .gitignore files work

58. HOW TO GET THOSE REASONS OFF THE PLANE: [HUMANELY] ▸

    Pay someone to develop IDE support (or do it yourself) ▸ Help me make the docs better ▸ Learn how .gitignore files work
