Is there some way to debug-print the contents of these groups as I go along
writing the qbs file?

Yes multiplex seems to be the correct option here.

Does this mean I need to know the exact list of files the code generator
outputs before it is run? Normally I'd only know that after having run the
code generator and look into it's output directory.

Currently I'm trying to print the contents of headerInputs and
templateInputs like this,

            var headerInputs = inputs["generator.in.headers"];
            var templateInputs = inputs["generator.in.templates"];

            console.warn("headerInputs: " + headerInputs);
            console.warn("templateInputs: " + templateInputs);

But the output says "headerInputs: undefined" and "templateInputs:
undefined"

I've hit some issue with the argument list/array. One of my argument
strings contain a wildcard '*', which casues that string to be wrapped with
'.

            var generatorArgs = [
                        product.sourceDirectory + "/api/some*files.h"),
                        "-o", product.buildDirectory + "/gen/",
                    ];

The actual command line has the first string wrapped in ' ' because of the
* in the string (wildcards are used for the input to the generator tool).
The code generator doesn't cope with the wrapping in '' (neither will "ls"
or any other command). Here is the resulting command line:

/home/xxxxx/bin/generator '/home/xxx/api/some*files.h' -o
/home/xxx/build-xxx-Desktop_Qt_5_10_0_GCC_64bit-Debug/qtc_Desktop_Qt_5_10_0_GCC_64bit_Debug/xxx.3a7a69e5/gen/

Why does the Command object add the '' around strings with * in them, and
is there some way to avoid that?

Best regards,
Ola
