Using Tags

Each tag gets a page listing its notes. Pattern tags, like idea/atomic-parts, mark ideas that turn up across unrelated topics.

Tags go in the front matter as an inline list: tags: [docs, tags]. Every tag gets its own page, and the tag index lists them all with a count and a filter box.

Topic tags and pattern tags

Most tags name a topic, like cooking or search. A few are what I call pattern tags, written with a slash: idea/atomic-parts. They mark an idea that turns up in notes on unrelated subjects, so a pattern tag's page reads like a thread through the notebook. Here, idea/atomic-parts connects this note, about splitting tags into parts, with Writing a Note, about keeping one idea per note. Follow the tag to see both.

Rules the build enforces

  • Tags that differ only in case, like Foam and foam, share one page, named with the spelling most notes use.
  • Each tag becomes a folder on disk, so a tag can't contain a backslash, an empty part (idea//x), or a part that is only dots (idea/..). The build stops and names the note.
  • Recipes have their own tags, used by the filters on the Recipes page rather than tag pages. See Recipe Format.
