Unfurling windows

An idea that windows onto itself, or two ideas that window onto each other, can constitute an infinite loop that could therefore unfurl forever. In order to prevent this, rookery has a notion of window unfurl, which is set to 1 by default.

When a window is called at a level of recursion greater than the unfurl budget, rookery renders a call to #window as a link to the idea’s standalone page rather than as transcluded content. It’s best to think of window unfurl as a multiplier, as the amount of work rookery needs to do multiplies when you raise it.

You can set the unfurl budget per window, or site-wide:

#show: rookery.with(window-unfurl: 1)
#window(<first-idea>)
#window(<first-idea>, unfurl: 2)

Here is a window on this selfsame idea. Because this documentation uses the default unfurl of 1, it only recurses as a window once, and then bottoms out as a link:

Concepts

[idea:config-reference]Argument reference

Parameter	Default	What it sets
`prefix`	`"idea"`	The namespace an idea’s name lives in; non-empty, no `:` (the separator is added for you). See referencing ideas.
`note-dir`	`none`	The directory the minted idea pages are written to. Left unset, it is `ideas` under the default prefix, and the prefix itself under any other — `prefix: "maths"` mints `maths/`, not `mathss/`. Names one directory: no `/` and no `:`.
`css-prefix`	`none`	The stem every class this package emits is built from. Left unset, it follows `prefix`, so renaming the name namespace renames `.idea-box` to `.note-box` along with it; set it to hold the classes still while the names move. See HTML class reference.
`window-unfurl`	`1`	How many levels of transclusion are allowed before a window bottoms out as a link to the idea’s own page. `0` allows none. See controlling window unfurl.
`theme`	`(:)`	The ten keys the package will style for you — five colors, three lengths, a font stack, and `tags-color`. Every key but `tags-color` is also a parameter in its own right, and the granular form wins. See theming a rookery.
`display`	`(:)`	What every idea and window in the rookery shows of itself, as a dictionary of the same nine flags `#idea` takes. This is the bottom of the stack: an idea or a window that leaves a key at auto is asking for the value set here. `date` and `tags` resolve to `false` when nothing is said, the other seven to `true`. Each key is also a parameter in its own right — `display-date: true` — and the granular form wins. See `#idea`.
`idea-page-template`	`none`	Your own chrome for the standalone page rookery mints per idea. See idea template.
`bibliography`	`none`	Typst’s own `#bibliography` arguments, for the single bibliography a rookery’s citations all draw from.
`index-page`	`true`	Whether to mint `ideas/index.html`, a landing page listing every idea in the rookery. It goes in the same directory the idea pages do, so a rookery that moved them with `note-dir` or `prefix` gets `maths/index.html` rather than `ideas/index.html`. Set it to `false` where your site already publishes an index of its own.
`refs`	`true`	Whether rookery installs the `show ref:` rule that renders `@idea:etal` as the idea rather than a figure number. Set it to `false` to keep Typst’s own behavior, or to install a rule of your own. See hyperlinks.
`hyperlink-target-minted`	`true`	Where every `@idea:etal` in the document lands: `true` on the idea’s standalone minted page, `false` in the context it was hatched in. The same parameter `#hyperlink` itself takes. Ignored when `refs` is `false`. See hyperlinks.
`syndicate`	`false`	Whether each minted page also carries a `<feeds:item>` beacon — the label `@rheo/feeds`’s `items()` reads by default — so a feed package can collect your ideas without either package importing the other. Off by default: a package should not write into another’s label namespace unasked. An idea with no date never gets one.
`page-titles`	`"title"`	What the context and backlinks footer on an idea’s page calls the pages it lists: `"title"` is Rheo’s own spine title, `"path"` the source path with the content directory and the extension dropped — `jobs/cfps`, `institutions`. Rheo derives a title from the file stem, so in a project with a page per directory every `index.typ` is titled ‘Index’, which is a poor answer to a footer asking where an idea was written; a path is longer and plainer, and unique by construction. A rookery-wide choice, since one idea’s footer disagreeing with another’s about what a page is called would be worse than either answer.
`invisible-tags`	`()`	Tags that leave no trace in the HTML: no pill in any hat, no `.idea-tag-<tag>` class on the heading, the card, an outline row or an index row, and no generated rule for a `tags-color` entry naming one. Filtering still sees them everywhere — `#window(tagged: ..)`, `#ideas`, `#idea-tag-names`, a search query — which is what makes an invisible tag usable as a build-level key. The presentational complement to `exclude-tags`, which drops the idea itself.
