Class ConsoleOutput
Object wrapper for outputting information from a shell application. Can be connected to any stream resource that can be used with fopen()
Can generate colorized output on consoles that support it. There are a few built in styles
errorError messages.warningWarning messages.infoInformational messages.commentAdditional text.questionMagenta text used for user prompts
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 color. See ConsoleOutput::styles() to learn more about defining your own styles. Nested styles are not supported at this time.
