I'm writing a primitive exporter for jupyter-book <https://github.com/executablebooks/jupyter-book>, which is a neat way to maintain static documentation and executable jupyter notebooks from the same source files. The source files are written in Myst flavored markdown <https://mystmd.org/>, so I started with a simpleminded fork of the gfm exporter <https://github.com/titaniumbones/ox-myst>. What I'd really like, though is something more like ox-hugo <https://github.com/kaushalmodi/ox-hugo>, which maintains a whole blog in a single org file. For this to work, I need to export each individual page of the "book" to its own markdown page. However, jupyter-book expects to find the title of the page in the initial first-level heading. So I'd like to retain the subtree "title" as a first-level heading, and demote the remaining headings to their original state within the larger org document.
Does anyone know of an existing exporter that already does this, from which I can steal? Or if not, how would you suggest I go about doing this? Thanks, Matt
