------------------------------------
Fix Version/s: 3.1.0
> Code Gen Framework
> ------------------
>
> Key: DAFFODIL-2202
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2202
> Project: Daffodil
> Issue Type: Improvement
> Components: Back End
> Affects Versions: 2.4.0
> Reporter: Mike Beckerle
> Assignee: John Interrante
> Priority: Minor
> Fix For: 3.1.0
>
>
> We have built an initial DFDL-to-C backend and code generator for Apache
> Daffodil on a dedicated development branch. Currently the C code generator
> can support binary boolean, integer, and real numbers, arrays of simple and
> complex elements, choice groups using dispatch/branch keys, validation of
> "fixed" attributes, and padding of explicit length complex elements with fill
> bytes. We plan to continue building out the C code generator until it
> supports a minimal subset of the DFDL 1.0 specification as described in
> Daffodil's Confluence here:
> * [Runtime2
> Design|https://cwiki.apache.org/confluence/display/DAFFODIL/WIP:+Daffodil+Runtime+2]
> We have some runtime2 todos (changes requested by reviewers) here:
> * [Runtime2
> ToDos|https://daffodil.apache.org/dev/design-notes/runtime2-todos/]
> The DFDL-to-C backend and code generator must meet the following acceptance
> criteria before we can submit a pull request to merge its development branch
> into the main branch:
> * [x] Works on "real" messages with sufficient complexity to demonstrate
> functionality
> * [x] Contains test schemas and TDML test cases covering all supported
> features
> * [x] Fully integrates these tests into 'sbt test' part of Daffodil's build
> process
> * [ ] Has instructions how to setup required C tool-chain elements on Linux
> and Windows
> We plan to convert an ever-increasing subset of Daffodil's DFDL 1.0
> specification TDML tests to run these tests on both the Scala and C backends
> too.
