require('strict')

--- @module CardLua
--- A reusable card primitive: a bordered, surface-coloured, rounded container
--- with a shared header row (title + description on the left, an optional
--- trailing element on the right) and an optional always-visible footer.
---
--- Specialized cards compose this:
--- * Module:CollapsibleCard wraps a <details> body as the card `content` and
--- supplies a chevron as the header trailing element.
--- * `renderLinkCard` is a built-in specialization: a static card whose
--- trailing element is a Module:ButtonLua button (e.g. "view on external
--- source") — for summaries that link out rather than expand in place.
--- * `renderMediaCard` is a built-in specialization for cards that lead with a
--- picture. It owns only the art — that it bleeds to the card's inner edge
--- without any negative margins, because `.t-card` carries no padding of its
--- own and the shell's `overflow: clip` trims the picture to the inside of
--- the border — and hands everything else to a content slot, with
--- `renderMediaBody` as the helper for the usual text block.

local button = require('Module:ButtonLua')

--- Builds the inner title/description block (no wrapper header row). Exposed so

--- A static card whose body is a header row with one or more link-out buttons

--- @class MediaCardReadout
--- @field label? string Left-hand label, e.g. "Ends in".
--- @field value? string Right-hand value: a count, a countdown, a price…
--- @field attrs? table<string, string> Attributes set on the value element, for
--- gadgets that animate or refresh it (e.g. a countdown target date).

--- @class MediaBodyProps
--- @field title string Required.
--- @field link? string Page the title links to.
--- @field kicker? string Overline above the title.
--- @field body? string Prose, or a wikitext list. A longer register than
--- the header row's one-line `description`. A `*` list renders as a
--- compact bulleted list — the shape Update: pages already use for
--- "what's new" — and each item should stay to one line, because a
--- wrapped item costs a slot in a card whose height is fixed by whatever
--- sits beside it.
--- @field readout? MediaCardReadout
--- @field more? string Read-more affordance at the foot of the body.
--- Rendered as styled text, never a second anchor: the title already
--- links to the same page, and on a stretch-linked card the whole
--- surface is that link, so an anchor here would only hand keyboard and
--- screen-reader users a duplicate stop to a place they have already
--- been offered. Hidden from assistive tech for the same reason — "read
--- more" is precisely the link text a screen reader user is taught to
--- distrust, and it carries nothing the title has not already said.

--- @class MediaCardProps
--- @field image? string File name for the leading art; a "File:" prefix is optional.
--- @field imageAlt? string Alt text. Defaults to empty, which is correct for
--- decorative art sitting next to a title that already names the subject.
--- @field imageWidth? number Width the file is RENDERED at, in px, not the size
--- of the slot — the art is cropped to fill, so this only needs to be
--- large enough to stay sharp. Defaults to 480.
--- @field layout? string 'split' (art beside the text, the default) or
--- 'banner' (art across the top). Split stays short; banner is taller for
--- the same content, which matters when the card sits above the fold.
--- @field content string|mw.html Everything that is not the art. Usually
--- `renderMediaBody(…)`, optionally followed by more elements — they
--- become further columns of the card's flex row, which is how a
--- countdown or any other aside gets in without this module growing a
--- prop for it.
--- @field stretchLink? boolean Make the whole card clickable. Requires a link
--- in `content` — the CSS stretches the title's anchor — so it pairs with
--- `link` on the body rather than on the card. Off by default, because a
--- card that swallows every click also swallows text selection.
--- @field footer? string Card footer, below a divider.
--- @field class? string

--- Wikitext for the leading art. `link=` is deliberately empty: the title
--- carries the link, and a second target over the picture gives keyboard and
--- screen-reader users a duplicate stop for the same destination.
---
--- @param props MediaCardProps

end

--- The visible cue that a card is clickable. A stretched anchor is invisible,
--- so without this the card gives no sign of being a link until a cursor is
--- already over it, and no sign at all to someone reading rather than pointing.

--- Builds the standard text block: overline, title, prose, and an optional
--- readout row pinned to the foot.
---
--- Exposed rather than inlined because the card takes a content slot, not a
--- fixed set of fields. A consumer that wants the usual text plus something
--- beside it composes this with whatever else, exactly as `renderLinkCard`
--- composes `renderHeader` with buttons.
---
--- The foot is bottom-anchored on purpose. Cards laid out in a row are
--- stretched to the tallest of them, and this decides where that spare height
--- lands: as a gap above the foot, which reads as deliberate, rather than as a
--- hole below everything, which reads as a mistake.

-- of opening a list. Only the FIRST item is affected, so the bug looks
-- like a typo in the wikitext rather than a rendering problem. Harmless
-- for prose: a leading newline inside a block element changes nothing.
root:tag('div'):addClass('t-card__body'):wikitext('\n' .. props.body)
