The idea here is to use the Ptolemy II code generator to generate C code for the Duktape Host.
Accessor Duktape Code Generation Slide from Edward A. Lee, "Accessors Tutorial: Bringing Sanity to IoT's use of Callbacks", February 24, 2016.
DE C Code Generator
- Make adapter for JS actor.
- Impl. get and send parts of API.
- Impl as C macros.
- Define JS fn that can be called from DukTape, then invoke fire().
- Generate the code once as a standalone program.
Status: 3/11/16: template code set up, example compiles and evaluates the contents of the script PortParameters, but the duktape host environment is not present.
Example
- See Ptolemy II for how to build from the svn repository
- Invoke the code generator with:
$PTII/bin/ptcg \
-generatorPackageList generic.program.procedural.c.duktape \
$PTII/ptolemy/cg/adapter/generic/program/procedural/c/duktape/adapters/ptolemy/actor/lib/gui/test/auto/TestComposite.xml
- The code will be generated in
~/cg, make will run and ~/cg/TestComposite will be run
Note that this example is not yet complete
Files to modify
The Ptolemy II Code Generator has many files, but fortunately, we only need to modify a few.
$PTII/ptolemy/cg/adapter/generic/program/procedural/c/duktape/adapters/org/terraswarm/accessor/JSAccessor.c This is where the C code is located that is used when generating code for the Ptolemy II JSAccess actors
