Overview

ANSI terminal escape sequences for styled console output. Extracted from Printer so style definitions are separated from printing mechanics.

Constant Summary collapse

ESC =

"\e["

RESET =

"#{ESC}0m".freeze

WEIGHTS = Weight codes

{ default: 0, bold: 1, light: 2, italic: 3 }.freeze

COLORS = Color codes

{
  black: 30, red: 31, green: 32, yellow: 33,
  blue: 34, magenta: 35, cyan: 36, gray: 37, default: 39
}.freeze

STYLE_DEFS = Style definitions: [weight, color]

{
  success_bold: %i[bold green],
  success: %i[default green],
  success_light: %i[light green],
  error: %i[bold red],
  failure: %i[default red],
  warning: %i[bold yellow],
  warning_light: %i[light yellow],
  source: %i[italic default],
  bold: %i[default default],
  default: %i[default default],
  muted: %i[light gray]
}.freeze

STYLES = Pre-computed ANSI escape strings for each style
