v5.9.0

An app's frame — layers, shortcuts, gestures, long lists, workers, frames —
and the compiler as a library an editor, a visual builder or an agent
builds on, each piece also a wf command.

Additions

• Layers (chapter 9). Popover, a Menu at
  its button, at an anchor or at a point (at:, for a context menu), with
  submenus, and Tooltip, drawn in the browser's top layer, so nothing
  clips or covers them. Each flips and slides to stay on screen; Escape
  closes the top one, a press outside closes what it is outside of, and
  focus goes back where it was.
• Shortcuts for an app (chapter 9). mod is ⌘
  on Apple's systems and Ctrl elsewhere; chords ("mod+k mod+s");
  keyIs(e, …) and keyLabel(…) for a table of commands that drives
  menus and a palette; a page, a component or app hears keydown and the
  window's events itself; trapFocus keeps focus inside a panel.
• Gestures (chapter 9). drag: and
  on receive(d) with a ghost, edge scroll and Escape; on longpress,
  on swipe; and Splitter between two regions, with its size kept.
• VirtualList (chapter 37): a
  long list drawn a window at a time, rows measured or of a fixed height,
  reveal: to scroll one into view, and V12 for a long list that is
  not windowed.
• worker (chapter 18): a Web Worker held
  like a connection, asked with .request(method, params) and heard with
  on message, restarted when it crashes; a store may hold connections.
• Frame (chapter 28): another page inside
  this one, its on message only that page's; A17 for a frame with no
  title.
• persist follows its key (chapter 12):
  key: Project.id keeps one value per project; in: .app names a
  storage the project gives itself, which may answer later.
• The policy names an app's own schemes and WebAssembly
  (chapter 33): meta.connect and
  meta.frame take ipc: or wfpreview:, meta.wasm lets a page compile
  WebAssembly, meta.style_elements lets a script write <style>.
• A build cache: only the pages an edit changed are pre-rendered
  again, in a session (BuildCache::in_memory) or across runs.
• An Image's literal src: in public/ is processed as an image
  declaration is: each width and format, its size, a <picture>.
• Previews of what a reader asked for: data-wf-motion="reduce" on
  the page's root stills every animation as prefers-reduced-motion does,
  and data-wf-validation="shown" shows every field's message as a failed
  submit does.
• Plurals by CLDR (chapter 21): the build picks
  each count's form by the default locale's rules (CLDR 48, the same
  table the browser's Intl.PluralRules reads), and exactly none is
  key.zero in any language.

For tools

Every one reads the project through a Vfs, so an editor's unsaved
buffers count (chapter 38).

• Printing and reprinting: webfluent::print, reprint and
  edit::rewrite_* change an element, a statement or a declaration in the
  tree and write the smallest edit, every other byte as it was.
• The node map both ways: each element's id, place, parent and what it
  is inside; the node at a caret; the Layers tree; wf build --studio
  stamps data-wf-node and writes nodes.json.
• Data an inspector draws from, each a command too: wf components
  (every component, built-in and the project's), wf theme (every token,
  its uses and its contrast), wf motion, wf rules (the validate
  rules, named patterns, every state's rules), wf scope FILE:LINE (what
  can be read at a place, typed), wf translations (what each locale
  lacks, what nothing names; --plurals), wf assets, wf config,
  wf commands; and style values read into their parts and written back.
• wf fix: one decided fix on every family that has a certain one,
  and fix-all per family.
• An agent's change set and context: webfluent::agent holds an
  agent's edits apart from the working tree, builds them before anyone
  reads them, and gives them back by file or by hunk; wf context is what
  an agent is given — the files, the problems, the components, the theme,
  the config with only its public env, and the guide.

Fixes

• A project's own animation (Card(animate: .Drop)) did nothing on an
  element that stood still; it plays.
• A refined type's open end (Number(0..10) took 10) and its after: and
  before: were not checked as the reader typed.
• Pre-rendered controls dropped name: and autocomplete:, and an
  Input with its own id: got a second one, so its label named nothing.
• A locale missing one plural form showed the default locale's form, two
  languages on one page; a site whose default locale is right to left was
  served left to right until a script ran; ar-EG was not right to left.
• A let in an action, a handler, an effect or a timer was offered by
  completion everywhere in its page, and listed as a store's member.
• I01 and I02 missed a t() in a page's header; I03 said a reader
  sees the key, where they see the default locale's message.
• Unsafe.Html without a sanitize(…) elsewhere put nothing in; a typo
  was reported once per check that found it; a page's own state env read
  the project's env.
• A comma between two style declarations made the browser drop both; it is
  an error.

Upgrading

See chapter 46: a comma between style
declarations, a field that accepted its range's open end, an animation
that now plays, a zero message that now shows, and a right-to-left
default locale are what a project may notice. Run wf check.
