Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

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.

Since:

  • 2.1.0
