# Open Files In An Editor

When using the pretty error page feature, whoops comes with the ability to
open referenced files directly in your IDE or editor.
This feature only works in case your php-source files are locally accessible to the machine on which the editor is installed.

```php
<?php

use Whoops\Handler\PrettyPageHandler;

$handler = new PrettyPageHandler;
$handler->setEditor('sublime');
```

The following editors are currently supported by default.

- `emacs`    - Emacs
- `idea`     - IDEA
- `macvim`   - MacVim
- `phpstorm` - PhpStorm
- `sublime`  - Sublime Text 2 and possibly 3 (on OS X you might need [a special handler](https://github.com/inopinatus/sublime_url))
- `textmate` - Textmate
- `xdebug`   - xdebug (uses [xdebug.file_link_format](http://xdebug.org/docs/all_settings#file_link_format))
- `vscode`   - VSCode (ref [Opening VS Code with URLs](https://code.visualstudio.com/docs/editor/command-line#_opening-vs-code-with-urls))
- `atom`     - Atom (ref [Add core URI handlers](https://github.com/atom/atom/pull/15935))
- `espresso` - Espresso
- `netbeans` - Netbeans (ref [xdebug.file_link_format](http://xdebug.org/docs/all_settings#file_link_format))

Adding your own editor is simple:

```php

$handler->setEditor(function($file, $line) {
    return "whatever://open?file=$file&line=$line";
});

```

You can add [IntelliJ Platform](https://github.com/pinepain/PhpStormOpener#phpstormopener) support like this:
```php

$handler->setEditor(
    function ($file, $line) {
        // if your development server is not local it's good to map remote files to local
        $translations = array('^' . __DIR__ => '~/Development/PhpStormOpener'); // change to your path

        foreach ($translations as $from => $to) {
            $file = preg_replace('#' . $from . '#', $to, $file, 1);
        }

        // IntelliJ platform requires that you send an Ajax request, else the browser will quit the page
        return array(
            'url' => "http://localhost:63342/api/file/?file=$file&line=$line",
            'ajax' => true
        );
    }
);

```
