From: Hannu Niemistö Date: Mon, 29 May 2017 09:23:24 +0000 (+0300) Subject: (refs #7245) The first version of decompiler for SCL compilations X-Git-Tag: v1.29.0~15^2 X-Git-Url: https://gerrit.simantics.org/r/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F64%2F564%2F2;p=simantics%2Fplatform.git (refs #7245) The first version of decompiler for SCL compilations It is intentional that the new fragment org.simantics.scl.compiler.decompiler is not added to the module listings in bundles/pom.xml, because currently this feature is intended only for development purposes.
