class Hanami::View::ERB::Filters::Trimming
Trims spurious spaces from ERB-generated text.
Deletes spaces around “<% %>” and leave spaces around “<%= %>”.
This is a copy of Temple::ERB::Trimming, with the one difference being that it descends into the sexp-tree by running ‘compile(e)` for any non-`:static` sexps. This is necessary for our implementation of ERB
, because we capture block content by creating additional `:multi` sexps with their own nested content.
