Wiki Facts

A fact is a property of a wiki page and its value: a spell’s level, its traditions, the class that casts it. Facts are held by the page beside its categories, not written in its text, so changing them adds no revision and a translation has the same facts as its page.

The examples use a Wizard page and the spells in a Spells category, such as Fireball and Shield.

Reading facts

A page with facts lists them under its text, above its categories, each under its property’s label. A value that names a page links to that page. Any other value links to the other pages that state it.

The Fireball page in the portal. Under the text, a Facts list shows Class wizard, pf2e 3 and Tradition arcane · primal, every value a link.

Under Named by, a page lists the pages whose facts name it, by property. A page shows up to 20 for each property; when more name it, all lists every one.

The Wizard page in the portal. Under the text, Named by shows Class fireball · shield · magic_missile.

Following a value that does not name a page opens Pages by fact, which lists the pages that state it. Its box holds the query, so you can change it and press Find again.

The Pages by fact page with pf2e=arcane in its box, listing fireball, shield and magic_missile.

A property with no label is shown by its key, as pf2e:rank is above. A fact that names a page you may not read is left out, and so is a page you may not read that names this one.

Properties

A page states only properties the game defines. Each property has a name in two parts, <group>:<name>, such as pf2e:level, and a type (see Value types). A property takes one value per page unless it allows several. A keyword property can list the keywords it allows; with none listed, it allows any. A label and a description tell readers what it records. Changing properties needs the wiki.admin permission.

Changing or removing a property leaves the facts pages already state. A page keeps a value its property no longer takes until someone changes that property on it, and a property defined again finds the pages that state it.

Value types

Type	A value is	Example	Ranges and comparisons
`number`	a whole number	`3`	yes
`decimal`	a number with a decimal point; no `1e3` or `1,000`	`12.5`	yes
`date`	a day, written year-month-day	`4675-05-02`	yes, a later day is above
`keyword`	a word, from the property’s list if it has one	`arcane`	no
`text`	any text, kept as written; it matches whatever its case	`First City`	no
`boolean`	`true` or `false`	`true`	no
`page`	a page, written as its title	`Help:Fireball`	no

A value of the wrong type is refused with the reason:

> @wiki/fact sandpoint/lore:founded=May 4675
WIKI: lore:founded is a date like 2026-10-23, not 'May 4675'.
> @wiki/fact sandpoint/lore:tax=1e3
WIKI: lore:tax is a number like 1.5, not '1e3'.

Properties in the portal

Wiki pages under Build & manage has a Fact properties card listing every property. + defines a new one; the pencil changes one and the bin removes it.

The Fact properties card: pf2e, page, several, labelled Class; pf2e, number, labelled Level; pf2e, keyword, several, allowing arcane, divine, occult and primal. Each row has an edit and a remove button.

The New property dialog: Property pf2e, Type keyword, A page may state several values switched on, Values arcane, divine, occult and primal, Label Tradition, and a description.

A definition the wiki refuses, such as a name without a group, is not saved, and the reason is shown.

Properties in the game

@wiki/property lists the properties and @wiki/property <property> shows one. @wiki/property <property>=<type> defines a property or changes its type, and @wiki/property <property>= removes it. @wiki/property <property>/<field>=<value> sets one of label, description, values (keywords separated by |) or multiple (yes or no).

Properties in a package

A package defines the properties its pages state under wiki_properties: in its package.yaml, which needs format: "1.17" or later; an older format ignores the block with a warning. A text, decimal or date property needs format: "1.18". Installing the package defines the properties, and removing it removes them. A property the game defined first stays the game’s. The install is refused unless that property has the same type, takes one value or several as the package does, and allows every keyword the package lists: a pf2e:tradition that takes one value refuses the package below, which states several.

format: "1.17"
wiki_properties:
  pf2e:tradition:
    type: keyword
    multiple: true
    values: [arcane, divine, occult, primal]
    label: Tradition

In the portal

Editing a page shows its facts below its categories. Each fact is a box with its property and its value; × removes it. Add a fact offers the properties the page can still take: a property that takes one value is not offered again once the page has it.

The editor's Facts row: pf2e Wizard, pf2e 3, and two pf2e boxes with keyword lists set to arcane and primal, each with ×, then Add a fact.

The value control follows the property’s type:

Type	Control	Example
Whole number	number box	`3`
Decimal	number box that takes a decimal point	`12.5`
Date	date picker	`4675-05-02`
Keyword	list of the property’s keywords	`arcane`
Text	text box	`First City`
True or false	true/false list	`true`
Page	text box, the page’s title	`Wizard`, `Help:Fireball`

Publish changes saves the facts with the rest of the edit. When a value is refused, the facts are not changed, the editor stays open, and the reason is shown under it:

The editor after Publish changes, with pf2e set to No Such Page. Under the save bar: pf2e names a page that does not exist: 'No Such Page'.

The editor for Sandpoint: Categories Settlements, then Facts with lore in a date picker showing 05/02/4675, lore first city, and lore 3.75.

A translation shows its page’s facts but cannot change them.

In the game

@wiki <page> shows a page’s facts under its text, then the pages that name it. In a client that can click, a page runs @wiki for that page, and any other value runs @wiki/query for the pages that state it.

@wiki/fact <page> shows a page’s facts alone. @wiki/fact <page>/<property>=<values> replaces one property’s values; separate several with |, and leave nothing after = to clear them.

WIKI: pf2e:level is a whole number, not 'two'.

Setting a fact is an edit, so the page’s edit requirements apply.

From softcode

wikifact(<page>) lists the properties a page has facts for. wikifact(<page>, <property>) returns that property’s values, separated by spaces or by a delimiter you give. A value that names a page comes back as that page’s reference.

Finding pages by their facts

A query lists the pages whose facts meet every condition. It takes up to four conditions:

Condition	A page meets it when it
`pf2e:tradition=arcane`	states that value; a page is named by its title
`pf2e:tradition=arcane\|divine`	states either value
`pf2e:tradition!=arcane`	does not state it
`pf2e:class=*`	states any value
`pf2e:class!=*`	states none
`pf2e:level>3`, `<3`, `>=3`, `<=3`	states a number, decimal or date above, below, at least or at most the value
`pf2e:level=1..3`	states a value from 1 to 3; leave an end off for no limit, as in `..2`
`lore:founded=4600-01-01..4699-12-31`	states a day in that century

A query needs one condition a page meets by stating a value, or a sort: != alone finds no pages. These settings go with the conditions:

Setting	What it does
`category=<name>`, `namespace=<name>`	limit where the pages come from
`sort=<property>`	orders the pages by any property but a page; a page that states none is left out
`order=desc`	puts the highest first; `order=asc`, the default, the lowest
`show=<property>\|<property>`	lists up to four properties’ values beside each page

Following a fact’s value opens Pages by fact, a box that searches the whole wiki: type the conditions, separated by commas, and press Find. When there are more pages than one answer holds, More reads the rest. With show=, the pages come as a table, a column for each property:

Pages by fact with pf2e=arcane, sort=pf2e, order=desc, show=pf2e|pf2e|pf2e. A table lists fireball (3, arcane · primal, wizard), magic_missile (1, arcane · occult, wizard) and shield (1, arcane · divine · occult, wizard · cleric).

A condition the wiki cannot answer is refused with the reason:

The box with pf2e=high, and under it: pf2e is a whole number, not 'high'.

In the game, @wiki/query lists the pages, and wikiquery() returns their references:

> @wiki/query pf2e:tradition=arcane, pf2e:level=1..3
+---------< 5 page(s) where pf2e:tradition=arcane, pf2e:level=1..3 >---------+

#-1 INVALID WIKI QUERY

With show=, @wiki/query lists the values in place of the revision and date. wikiquery() returns pages only, so it refuses show=; read a page’s values with wikifact().

A query leaves out every page you may not read.

A query in a page’s text

A ::: facts block in a page’s text lists the pages its query finds, each time the page is read, so the list keeps up with the wiki. The conditions and settings follow facts on the opening line, as @wiki/query takes them, and a bare ::: closes the block. It is a query, not softcode, so it runs nothing.

Every arcane spell, highest level first:

::: facts pf2e:tradition=arcane, sort=pf2e:level, order=desc, show=pf2e:level|pf2e:class
:::

The Arcane spells page in the portal: its sentence, then a table of fireball (3, wizard), magic_missile (1, wizard) and shield (1, wizard · cleric).

@wiki shows the same table, up to 20 pages, with a link to the rest. A query the wiki cannot answer shows the reason where the block is. Elsewhere, such as rendermarkdown(), the block is a note that the list is on the web portal.

------------------------------------------------------------------------------

Filtering a category

A category page lists, above its pages, each property its pages state, with the values they state and how many pages state each. A property shows its twelve most stated values. When a number, decimal or date property has more than six values, they are counted in up to six ranges instead: ranges of equal width for whole numbers, and for decimals and dates ranges of about as many values each, from one value a page states to another. Text that differs only in case is one value.

The spells category page. Above its four pages: Class with wizard 3 and cleric 2, Level with 1 2 and 3 1, and Tradition with arcane 3, divine 2, occult 2 and primal 2.

Choosing a value replaces the category’s pages with the pages that state it, as a table with a column for each property you chose from. Choosing a second value of the same property finds pages that state either; a number, decimal or date takes one value or range at a time. Each property counts the pages that meet your other choices, so its other values stay listed. Clear filters shows the category’s pages again.

The same page with Level 1 and Tradition arcane chosen: 2 pages match, then a table of shield and magic_missile with their traditions and level. Tradition now counts arcane 2, occult 2 and divine 1.

The Settlements category page with the Founded range 4407-01-20 to 4540-06-01 chosen: 2 pages match, then a table of Korvosa (4407-01-20) and Riddleport (4540-06-01). Motto and Tax rate count only those two.

In the game, @wiki/facets <category> lists the same counts, and conditions after = narrow them. In a client that can click, a value narrows the list, and List them runs @wiki/query for the pages counted.

The fact index

Queries read an index of every page’s facts. The server builds it in the background when it starts, and every edit keeps it up to date from then on. Until it is built, a query answers that the index is still building: #-1 WIKI INDEX BUILDING in softcode.

@wiki/fact/index shows how far the index has come. @wiki/fact/index rebuild empties it and builds it again, and needs the wiki.admin permission.

> @wiki/fact/index
WIKI: The fact index is ready: 10 pages.

The in-game help has the same in short form: help wiki facts, help wikifact() and help wikiquery().
