Release Notes — Termina 0.13.0

Release date: 2026-06-17

Features

Gradient primitives, GraphNode, and ProgressBarNode (#298) — Jan (@st0o0)

A major visual components update with gradient coloring support across the board.

  • Color.Lerp — Linear RGB interpolation between two colors
  • Gradient — Immutable multi-stop gradient with color stop interpolation
  • GraphNode — Reactive, self-invalidating layout node for live scrolling graphs in four styles:
    • Blocks — Filled block columns (▁▂▃▄▅▆▇█)
    • Outline — Top edge only, sparkline feel
    • Braille — Double vertical resolution using braille characters
    • Ascii — ASCII fallback for terminals without Unicode
    • All styles support gradient coloring by row height
    • Configurable timer interval or data-driven updates
  • ProgressBarNode — Single-row progress bar with:
    • Gradient fill across the bar width
    • Configurable fill/empty characters and colors
    • Optional formatted label (e.g., "{0:P0}" for percentage)
  • Full API docs and interactive gallery demo

Color and icon support for toast notifications (#296) — Jan (@st0o0)

Toast notifications can now be customized with colors, icons, and positions.

  • ToastOptions.Color — Optional color override for toast border
  • ToastOptions.Icon — Optional icon string displayed in the toast
  • Built-in presets:
    • Success — Green border, ✓ icon, Top Right
    • Error — Red border, ✗ icon, Top Right
    • Warning — Yellow border, ⚠ icon, Top Center
    • Info — Cyan border, ℹ icon, Bottom Right
    • Custom — Magenta border, 🚀 icon, Bottom Center
    • Default — No overrides (unchanged behavior)

Bug Fixes

Parse CSI Z (backtab) as Shift+Tab (#297) — Jan (@st0o0)

In legacy terminal mode, the CSI Z escape sequence (ESC [ Z) was silently dropped. It now correctly maps to Shift+Tab, restoring expected backward-tab behavior.

ScrollableContainerNode ignoring bounds.Y (#301)

ScrollableContainerNode was ignoring bounds.Y during layout, causing it to overwrite content above the scrollable area. The layout calculation now correctly respects vertical bounds.

Docs

  • Embedded animated GIF demos for Toast and Graph/Progress components (#302)
