Resolves #3341
Custom module hides empty output, e.g. when a worker returns
{}
as json. But when using other content in the format, e.g. to add an icon before or after output, it's no longer possible to have the module hidden.This PR addresses this by adding a config option
hide-empty-text
, when true,text_
is checked for empty rather thanstr
.I realise I forgot the manpage, coming up in a second :P
