fix: honour a boolean option written as a bare YAML false - #42
Merged
Conversation
The shared metadata accessor guarded on truthiness, so `auto-filename: false` and its siblings were read as absent and the default applied in their place. Only the quoted string worked, which the site itself had adopted. Also corrects the reference and the examples page. They said a derived filename frames nothing in HTML, which is wrong: Quarto builds its wrapper before this filter runs, so the block carries a marker class instead and the injected script builds the window at page load, as it does for the rest of the HTML chrome. Checked in a browser rather than in the static output.

auto-filename: falseand its siblings were read as absent and the default applied instead. Only the quoted string worked, which this site had adopted.Verified in a browser, since the HTML chrome is assembled by script at page load and a static grep cannot see it:
The same check also disproves a claim the documentation carried, that a derived filename frames nothing in HTML. With
auto-filename: truethe block is framed and titledyaml, by the script rather than by Quarto's wrapper. The reference and the examples page are corrected, and the site drops the quoted workaround.
