[Console] OutputFormatterStyle for html colors

[rvanlaak]

Currently the OutputFormatter of the Console command nicely colors the output when used on cli.

Some of the command I've created are executed via a backend setup module, the output is returned to the controller using a StreamOutput

    $application = new Application($this->get('kernel'));
    $application->setAutoExit(false);

    $fp = tmpfile();
    $output = new StreamOutput($fp, StreamOutput::VERBOSITY_NORMAL, <new HtmlFormatter()>);

    $application->run(new ArrayInput($options), $output);

Feature: a new OutputFormatterStyle to format the output according with html colors / bold / etc

This could be part of the DX-initiative (?)

this would be quite complex to write, because this would require escaping any other HTML, which will be a huge pain.
It is probably much easier to use https://github.com/sensiolabs/ansi-to-html to convert the ANSI colors to HTML (which is what SensioLabs Insight uses AFAIK)

This is great! Would be a nice addition for the documentation of the Console component.

i think this could be described in a cookbook. You should open an issue on the symfony-docs repo suggesting it (or even better contribute to the doc with such a cookbook).

anyway, closing this issue as @fabpot agrees with me that the converter is a better way to handle it.

Adding it to the Cookbook is fine, will do that when I've got some spare time at the end of this week.

An addition to the docs is a great idea! I didn't know about the sensiolabs library - I have a use for this in a project :).
