How to get sterr output after command execution?

I need to log it

Hey @gam6itko,

First of all, thank you for your interest for snappy and sorry for the long awaited answer. Currently there's no way in the library to do it. So merely you need to overload the current generator or just add some dump calls where you want.

I created a little issue some time ago about backporting the LoggableGenerator from snappy-bundle to this lib (see #258). As soon as I've got some time to do it, I will. Or I'd be glad to merge any PR doing it :)

I added logging capabilities in order to ease debugging of snappy/wkhtmltopdf. You can now call setLogger on the generators to enable logging. By default generators use a NullLogger. See #264.
