Experiment to auto-generate C++ classes based on GDTF Schema

Play with GDTF, using xsdcxx and xerces to generate C++ code from the gdtf.xsd provided Schema file.

TODO

It kind of works :)

If you get this error, it's because the namespace is not defined...

/home/hip/dev/gdtf-cxx/testdiablo.xml:3:3 error: no declaration found for element 'GDTF'

To make it work, the GDTF description.xml GDTF node should look like this:

<GDTF DataVersion="1.0" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:t="http://schemas.gdtf-share.com/device" 
  xmlns="http://schemas.gdtf-share.com/device"
  xsi:schemaLocation="http://schemas.gdtf-share.com/device gdtf-libraries/gdtf.xsd" 
 >

setup

To get going, for ubuntu install depends...

$ sudo apt update

# install xerces (https://xerces.apache.org/index.html) and xsdcxx (https://linux.die.net/man/1/xsdcxx)
$ sudo apt install Xerces-C++ xsdcxx  

$ git clone https://github.com/hippyau/gdtf-cxx.git 

$ cd gdtf-cxx

# you can get the gdtf.xsd from https://gitlab.com/petrvanek/gdtf-libraries
$ git clone https://gitlab.com/petrvanek/gdtf-libraries.git

$ chmod +x *.sh

usage

# generate (or overwrite) C++ classes from the gdtf.xsd file in the submodule 
$ ./gen.sh

# compile example printer parser
$ ./compile.sh

I got a GDTF file, extracted a description.xml and renamed it testdiablo.xml. I then had to edit the xml to include the namespace in the gdtf.xsd file:

 <GDTF DataVersion="1.0" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://schemas.gdtf-share.com/device gdtf-libraries/gdtf.xsd" 
  xmlns:t="http://schemas.gdtf-share.com/device" 
  xmlns="http://schemas.gdtf-share.com/device"
 >

and could then run the example printer... until it had an error :)

# run the printer example
$ ./impl ./testdiablo.xml

which produced...
