A few questions about datafiles:

1) Text datafiles with inline contents (instead of pulling from a source file) do not seem to get turned into generated datafiles. Is that by design?

2) It appears that the datafile generation step for text files get redered with native line endings, which is not desirable for something that will get rendered into a preformatted textbox. If you generate datafiles on a windows machine, the datafile looks like it is double-spaced when rendered in HTML due to CRLF's. Anyone have a suggestion on how to disable that behavior?

3) I see that runestone-activecode's can have a datafile attribute. But I can't figure out what it does. Can anyone point me to documentation?

Thank you!

Just following Runestone's lead, iirc. Its what the Javascript can handle or
expect.

Stop using Windows?

These are generated by Python, and I recall there being settings that influence
line endings (generally) so perhaps we can control this at that point in the
process.

Find this example in the Runestone version of the sample book:

Thanks Rob!

I was under the mistaken impression that the lack of a generated file was going to prevent it from getting into the Runestone DB. I can see now that the inline content is getting picked up as intended.

lol @ #2

I'd love to see this fixed, but I don't have a Windows machine to work on.
There's no end of stuff out there about Python, Windows, Linux, \n, \r\n, etc.
Open in binary mode, or use "io.open( ) with keyword argumant "newline", and so on.

Action begins in pretext/python.py at current line 724.

Is this confined to data from some external text file, or data authored inline
in source PreTeXt, or does it happen in both situations?
