Hi Julian,
Let's use Google Meet since it has the best captions. I can schedule the
Google Meet if you can't and I'm happy to discuss the topic on Sat, Sun, or
Mon, although I don't know if anyone else like Mike who might want to join us
is available before Tues. This Mon is Memorial Day in the USA and people may
have special plans during a three-day holiday weekend.
Mike and anyone else interested, do you want to join the discussion and which
days/times between now and Tues work for you?
Thanks!
John

Hi John,
thanks for taking the initiative here and sorry for beeing a bit silent in the
last weeks / monthts.
Especially I hope that all of you are well!
I can offer to do a little Zoom / Teams / Google Hangout Webmeeting later today
or tomorrow (or also next week) to discuss the topic a bit and get started
together.
What do you think?
Julian

I'd like to work on the code generation framework
(https://issues.apache.org/jira/browse/DAFFODIL-2202) initiated by Julian
Feinauer and discussed by Mike Beckerle in the Daffodil design notes
(https://cwiki.apache.org/confluence/display/DAFFODIL/WIP%3A+Daffodil+Runtime+2).
Steve suggested that I start a discussion on the dev mailing list.
Mike said that our first goal should be to get a very simple code-gen
example working. Write a schema that describes a single element (a 32-bit
binary int), get Daffodil to compile that schema, generate the source code for
a parser, compile that parser, and run a test against it showing it is working
as expected:
<xs:element name="uI_01" type="xs:unsignedInt" />
<tdml:parserTestCase name="unsignedInt_binary"
root="uI_01" model="SimpleTypes-binary"
description="Section 5 Schema types-unsignedInt - DFDL-5-018R">
<tdml:document>
<tdml:documentPart
type="bits">00000000000000000000000000001000</tdml:documentPart>
</tdml:document>
<tdml:infoset>
<tdml:dfdlInfoset>
<uI_01>8</uI_01>
</tdml:dfdlInfoset>
</tdml:infoset>
</tdml:parserTestCase>
@Test def test_unsignedInt_binary() {
runner.runOneTest("unsignedInt_binary") }
Julian has contributed some code
(https://github.com/apache/incubator-daffodil/compare/master...JulianFeinauer:feature/daffodil-2202-initial-codegen)
and Mike has made some changes to it
(https://github.com/apache/incubator-daffodil/compare/master...mbeckerle:daffodil-2202-initial-codegen).
We will have to solve a lot of problems before we can run even that test,
so it would be a big step forward. I want all the help I can get to get this
tiny first example working. I would welcome a suggestion from Julian, Mike,
Steve, or anyone else how to continue what's been done so far.
Thanks,
John
