Description Ed Willink CLA 2016-02-03 04:34:15 EST 
The QVTi debugger should be useable for QVTr/QVTc iff the stepped AST can be mapped to the QVTc/QVTr source lines. Just need the compiler chain to maintain a source AST to QVTi AST mapping.

Suggest adding a DebugTraceBack class to QVTbase, with a Transformation.ownedDebugTraceBacks to host the target to source mappings.
Comment 1 Ed Willink CLA 2016-05-02 17:38:38 EDT 
DebugTraceBack was added but it adds quite a substantial bloat with references to xmi:id-less elements.

Debugging wom't make it for Neon so drop DebugTraceBack.

Better a compressed string representation, perhaps allocating ids locally in eAllContents order.

<debug model="My.oclas" ids=":23 :2 2:4 7:9">

Host model 1 => referenced 23
Host model 2 => referenced 2
Host model 3+2 => referenced 4
Host model 6+7 => referenced 9
