Folio

Appearance

Markdown support ​

GitHub Flavored Markdown ​

Tables, task lists, strikethrough and syntax-highlighted fenced code blocks. Code blocks have a copy button on hover.

Front matter ​

YAML front matter is hidden. Folio reads these fields from it:

FieldUsed for
titleThe document's name in the list
statusThe status icon, filters and the line above the document
tagsFilters and the hover card
  • [[Note]], [[Note|alias]], [[Note#Heading]] and [[#Heading]] links, resolved by file name anywhere in the workspace, nearest first.
  • ![[image.png|300]] image embeds.

Math ​

KaTeX: $E=mc^2$ inline, and $$…$$ or ```math blocks. Inline math follows GitHub's rules, so prices like "$5 and $10" stay text.

Mermaid diagrams ​

```mermaid blocks are drawn in the current light or dark theme. A diagram that sets its own colours (rect rgb(…), fill:) or theme (%%{init: {"theme": …}}%%) is drawn on a card of the background it was written for, so its text stays readable in either theme. Hover a diagram and click its expand button, or double-click it, to view it in the whole window with zoom and pan (keys).

Each heading has an anchor made from its text, as on GitHub, so [see Retries](#retries) goes to the ## Retries heading. Repeated headings get numbered anchors: the second ## Added is #added-1.

  • Images from the workspace, relative to the document, and from the web. Hover an image and click its expand button, or double-click it, to view it in the whole window with zoom and pan, as for a diagram. Small images, such as badges, and images inside links don't open.
  • Links to other files, such as [data](report.pdf), open in their app. Links to scripts, executables and HTML are shown as unavailable.
