Use of sphinx open directive for conditional content

[tobydriscoll]

Not sure if this is a feature request, bug report, or just ignorance.

I'm writing a book and was planning to use only directives to include content only when a "solutions" tag is set. In Sphinx you set these tags by a command line flag, or by a tags.add('solutions') in conf.py.

However, I'm not seeing any way to enact either option within JB. I can add tags to the config file, put that does not put it into the proper syntax for Sphinx. For example,

sphinx:
  config:
    tags: [solutions]

produces the line

tags = ['solutions']

from jb config sphinx, but then building gives the error

WARNING: unknown config value 'tags' in override, ignoring

and the only content is still ignored.

Ah interesting - there are definitely something you can do in Sphinx that you cannot do with YAML configuration (what Jupyter Book uses). That I think is the issue here :-/ if this is really important, you could try building your book entirely with sphinx?
