# tuika 0.10.0

Released 2026-08-17. [crates.io](https://crates.io/crates/tuika/0.10.0) · [docs.rs](https://docs.rs/tuika/0.10.0/tuika/) · [GitHub release](https://github.com/everruns/tuika/releases/tag/v0.10.0)

Released alongside `tuika-charts` 0.1.1, `tuika-codeformatters` 0.4.3,
`tuika-html` 0.1.3, and `tuika-mermaid` 0.3.1. Their tuika dependency
requirements now track 0.10.

## Added

- **Components**: `ProgressBar::label_style` styles the caption set by
  `label`, the same theme-by-default/explicit-override pattern as `colors`. The
  trailing `NN%` of `percent` stays separate chrome on the theme's muted style.
- **Components**: `SelectionAnchor` selects how `Table` and `SelectList` window
  themselves around the selection when they resolve their own window —
  `Center` (today's recentering behavior, still the default) or `Edge`, which
  moves the window only when the selection would leave it.
- **Virtualization**: `VirtualWindow::keeping` is the edge-following policy as a
  pure function of the caller's current start; `SelectViewportState::resolve`
  now uses it, so the persistent and stateless paths share one implementation.
- **Charts**: both axes carry tick labels, so a chart states its scale instead
  of leaving the reader to guess it. Ticks land on round values (a power of ten
  times 1, 2, 2.5, or 5) and label precision follows the tick step.
  `Axis::format` replaces the numeric formatter, `Axis::ticks` targets a tick
  count, and `Axis::hidden` opts an axis out. Labels are drawn as cells in
  **both** render modes — the graphics image covers the plot only — so the same
  numbers land in the same cells whether or not the terminal has graphics.

## Changed

- **Breaking:** Mouse capture is now opt-in in alternate-screen mode, preserving native OSC 8
  link activation, terminal selection, and scrolling by default. Applications
  that need pointer or wheel events use `ScreenMode::with_mouse_capture`,
  `MouseCapture::Enabled`, or `AltScreen::enter_with_mouse_capture`; captured
  sessions may use runner selection and `ctrl_click_url` as application-side
  fallbacks.
- `MarkdownState::links` preserves labeled and bare hyperlink targets across
  incremental updates, settled-prefix caching, wrapping, and resize, so hosts
  drawing streaming lines can apply native OSC 8 links without re-parsing.
- **Charts**: `Axis::categories` names positions instead of measuring them,
  which is what most bar and area charts actually want. `Chart::stack` combines
  bar and area series — `Stack::Normal` sums them, `Stack::Percent` scales every
  position to 100 — while unstacked bar series split their category band into
  slots and sit side by side. `Chart::horizontal` swaps the axes so a category
  gets a whole row of width for its name. `Series::markers` and `Series::labels`
  annotate samples, `Chart::focus` marks one position and lists every series'
  value there, and `Series::donut` with `Chart::center` draws a ring. A rule is
  drawn along zero whenever the value domain straddles it.
- **Breaking:** chart axis labels are on by default, so a chart that previously
  filled its whole area now gives a few columns to the y-axis gutter.
  `Chart::x_axis` and `Chart::y_axis` with `Axis::hidden` restore the old
  geometry exactly; the x labels reuse the margin row the plot already reserved
  and cost no plot height. Aligning both renderers on one cell grid also removed
  the graphics path's internal margins, so a graphics plot now covers the same
  data cells its portable counterpart does.

## Fixed

- **Charts**: graphics-mode plots are transparent where nothing is drawn rather
  than filled with the theme background, so cell-drawn text — value labels, a
  donut's centre text — is no longer hidden by the image composited over it.
- **Charts**: automatic y domains reach the zero baseline whenever a chart
  carries a bar or area series. These marks encode their value in the filled
  span, so a domain starting at the data minimum drew a bar of 1 beside a bar
  of 5 as a sliver beside a full column — a ratio the data never contained.
  Line, step, and scatter series are read as positions and keep the tighter
  domain that resolves their variation; `Chart::y_domain` still overrides both.
