This should go in the FAQs because I had to figure this out myself just  this week.&nbsp; The toolset.flags rule sets your TOOLSET variable "on"  $(targets) for the actions block.&nbsp; The undocumented magic method  to retrieve that value in a rule context is the following:<br>  <br>  local toolset = [ on $(targets) return $(TOOLSET) ] ;<br>  <br>  Voila!&nbsp; <br><br><b><i>Jaroslav Gresula &lt;jgresula@seznam.cz&gt;</i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;">  Could someone advise me how to retrieve value of a feature within a <br>rule? I followed an example from the docs which uses the toolset.flags <br>rule but with no luck.<br></blockquote><br>
