CAN I USE THIS TO MAKE MY OWN SYNTAX?

Slide 48

Slide 48 text

OTHER THINGS: ▸ immutable classes ▸ short arrow functions

Slide 49

Slide 49 text

WHY WOULD I USE THIS?

Slide 50

Slide 50 text

REASONS TO USE: ▸ You like the syntax I've shown ▸ You repeat code ▸ You repeat code

Slide 51

Slide 51 text

REASONS TO USE: ▸ New syntax could be clearer and more concise ▸ You want features from other languages ▸ You want to support old PHP

Slide 52

Slide 52 text

process .."/helpers.pre";

Slide 53

Slide 53 text

process __DIR__ . "/helpers.pre";

Slide 54

Slide 54 text

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

Slide 55

Slide 55 text

process __DIR__ . "/helpers.pre";

Slide 56

Slide 56 text

process .."/helpers.pre";

Slide 57

Slide 57 text

REASONS NOT TO USE: ▸ No IDE support ▸ You have to teach developers new syntax ▸ You have to learn how .gitignore files work

Slide 58

Slide 58 text

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
