Fast answer:

sed ':a;N;$!ba;s/\n/ /g' file

1. :a create a label 'a'
2. N append the next line to the pattern space
3. $! if not the last line, ba branch (go to) label 'a'
4. s substitute, /\n/ regex for new line, / / by a space, /g global match (as many times as it can)

Laravel's Dependency Injection Container in Depth

Translations: Korean (by Yongwoo Lee)

Laravel has a powerful Inversion of Control (IoC) / Dependency Injection (DI) Container. Unfortunately the official documentation doesn't cover all of the available functionality, so I decided to experiment with it and document it for myself. The following is based on Laravel 5.4.26 - other versions may vary.

Introduction to Dependency Injection

I won't attempt to explain the principles behind DI / IoC here - if you're not familiar with them you might want to read What is Dependency Injection? by Fabien Potencier (creator of the Symfony framework).

document.addEventListener('invalid', (function(){
    return function(e) {
      //prevent the browser from showing default error bubble / hint
      e.preventDefault();
      // optionally fire off some custom validation handler
      // myValidation();
    };
})(), true);
