monet_ui 1.2.2

Dynamic, user-friendly, design themes.

1.2.2

• The package no longer includes Python bytecode from lib/fonts/. No code changes.

1.2.1

• AnyBackground.sharedBorder: removed a tiebreak that never applied. 1.1.2 and 1.2.0 said ties go to a tone outside every surface's tone, then to the darker; tied tones mirror each other around the surfaces' midpoint, so both are outside or both inside, and the darker always won. No change in results.

1.2.0

• MonetThemeData.transitionProgress: how far through a theme transition a theme is, 0..1, 1 at rest. The shared progress that lerps backgroundTone, contrast and scale. Lerp values solved once per endpoint by it, instead of solving each frame.
• AnyBackground.sharedBorder is fast again uncached: it checks tones in order of preference and stops at the first that works, with the same answers as 1.1.2. 1.1.2 checked all 101 and was 3 to 20 times slower than 1.1.1. Same in the JS port.
• AnyBackground.clearAnswerCaches, for benchmarks (@visibleForTesting).

1.1.2

• AnyBackground.sharedBorder: of the tones that work, picks the one nearest its farthest surface, instead of the first working tone darker than every surface, then lighter, then between. Surfaces far apart in tone no longer get a near-white or near-black border when a tone between them works: Telosnex's T84, T53 and T17 colors went from T94 to T38. Ties go to the darker. Same in the JS port.

1.1.1

• Fit Latin line heights to A-Z and a-z, excluding accented letters. This tightens many line heights and changes vertical placement in single-line controls too. The font-metrics patch centres this smaller envelope even when compact line heights are disabled; natural line heights keep their original total height. Accents, punctuation, and other scripts can extend outside the measured envelope. Increase line-height clearance if needed to avoid overlap. The default clearance stays at 0.08 and the minimum baseline distance stays at 1.0 times the requested size.

1.1.0

• Size adjust (docs/design/ADR_font_size_adjust.md in telosnex), off by default: MonetFonts.install(sizeAdjust: true) scales each Google Font's letters to the reference size in its bytes (head.unitsPerEm), like CSS size-adjust, instead of in its font size. Fallback fonts, such as emoji, then keep their own size. With it on, visualHeightScaleForFontFamily is 1.0 for adjusted fonts, and the em accessors (rasterCapHeightEmForFontFamily, latinInkForFontFamily, ...) give values in the em of the loaded font. New: font_size_adjust.dart (fontSizeAdjustEnabled, isFontSizeAdjusted, fontEmScale, adjustedUnitsPerEm), rasterVisualHeightScaleForFontFamily, kFontSizeAdjustExcludedFontFamilies (Bytesized), and the unitsPerEm argument of patchFontAscentDescent. The generator fails on a CFF font.
• Font code from telosnex (docs/design/ADR_fonts_in_monet_ui.md there):
  • font_file.dart: fontTableRecords, cmapCodePoints, colorTables, unitsPerEm, fontOutlines, hasLatinLetters.
  • text_metrics.dart: snapFontSize, withFontLineHeight, lineHeightForTextScaler, capHeightCentringShift, capHeightShiftForTextStyle.
  • monet_fonts.dart: MonetFonts.install(), the one font transform, and loadMonetFont for tests.
  • fonts/tooling/google_fonts_source.dart (not exported; dart:io): the reader of the google_fonts package, from tool/generate_fonts.dart.
  • crypto is now a dependency.
• Font data: the font's cmap decides whether it has Latin letters, not the catalog's latin subset. 111 more families get a line height, among them the 104 Playwrite families and the math fonts.
• Font data: a font that maps an accented letter to an empty glyph is measured from A–Z and a–z (Knewave).
• Font data: a family with only italics is measured from its italic (Molle). It gets a visual-height scale.

1.0.1

• Add MonetGdtRule20261030 (extract/monet_gdt_rule_2026_10_30.dart): the color rule that monet_gdt 2026.10.30 is trained on. It chooses colorful colors before large areas, and needs 128 QuantizerCelebi clusters. It is slower than ScorerTriad and can pick small colorful areas; see the file header.

1.0.0

• First release on pub.dev, as monet_ui (the repository was libmonet). Its library is package:monet_ui/monet_ui.dart.
