termistyle 0.0.1

Standalone terminal styling primitives — ANSI color palettes, box-drawing glyphs, display features, themes, and text utilities for CLI applications.

0.0.1

Extracted the standalone styling system from terminice_core into its own package so that any Dart CLI tool, prompt library, or terminal renderer can share the same visual language without pulling in the full terminice stack.

• Theme system (PromptTheme): Unified composition of colors, glyphs, and display features with 11 built-in themes (dark, minimal, compact, matrix, fire, pastel, ocean, monochrome, neon, arcane, phantom) and full copyWith support.
• Color palettes (TerminalColors): 14 ANSI escape fields with 10 built-in presets spanning 8-color, 16-color, and 256-color terminals.
• Glyph sets (TerminalGlyphs): Box-drawing borders, arrows, and checkbox symbols with 9 built-in presets (unicode, ascii, rounded, double, heavy, dotted, arcane, phantom, minimal) plus matchingCorner() for balanced frames.
• Display features (DisplayFeatures): Behavioral flags (borders, bold titles, inverse highlight, connector lines, hint style) with 6 built-in presets (standard, minimal, compact, verbose, clean, focus).
• Semantic tones: BadgeTone (neutral, info, success, warning, danger) and StatTone (info, warn, error, accent, success, neutral) for theme-resolved semantic coloring.
• Spinner frames (SpinnerFrames): Enum with three animation styles (dots, bars, arcs) and their Unicode character sequences as top-level constants.
• Inline styling (InlineStyle): Theme-aware badge, spinner, progress bar, icon, and text coloring utilities that return styled strings without writing to stdout.
• Syntax highlighting (SyntaxHighlighter): Theme-aware line-level highlighting for Dart, JSON, and shell with auto-detection.
• Frame rendering (FrameRenderer, FramedLayout): Bordered title, connector, bottom line, and gutter generation driven purely by the active theme.
• Table rendering (TableRenderer, ColumnConfig, ColumnAlign): ANSI-aware column sizing, zebra-striped rows, and flexible alignment per column.
• Text highlighting (highlightSubstring): Case-insensitive substring match coloring using the theme's highlight color.
• Tone resolution (toneColor): Maps a StatTone to the corresponding ANSI color through the active theme.
• Text utilities: stripAnsi, visibleLength, padVisibleRight/Left/Center, truncate, truncatePad, padRight, padLeft, clampInt, maxOf, minOf, columnWidth, columnWidthVisible.
• Zero dependencies. SDK constraint >=2.17.0 <4.0.0.
