Last year I wrote a small utility called notesync to assist in my digital garden publication workflow. Thes script reads the frontmatter of my notes and looks for public: true. Then it copies notes from my private obsidian vault over to a public folder ready to be processed and published by quartz.
Today I noticed that content that was in a subfolder was not being detected or synchronised properly. I worked out that the Python glob module has a recursive=true flag that I had forgotten to set. Setting this flag has resolved the problem and content in sub-sub directories is now appearing on my site.
