/**
|
|
* Object wrapper for outputing information from a shell application.
|
|
* Can be connected to any stream resource that can be used with fopen()
|
|
*
|
|
* Can generate colourzied output on consoles that support it. There are a few
|
|
* built in styles
|
|
*
|
|
* - `error` Error messages.
|
|
* - `warning` Warning messages.
|
|
* - `info` Informational messages.
|
|
* - `comment` Additional text.
|
|
*
|
|
* By defining styles with addStyle() you can create custom console styles.
|
|
*
|
|
* ### Using styles in output
|
|
*
|
|
* You can format console output using tags with the name of the style to apply. From inside a shell object
|
|
*
|
|
* `$this->out('<warning>Overwrite:</warning> foo.php was overwritten.');`
|
|
*
|
|
* This would create orange 'Overwrite:' text, while the rest of the text would remain the normal colour.
|
|
* See ConsoleOutput::styles() to learn more about defining your own styles. Nested styles are not supported
|
|
* at this time.
|
