An xterm 256 color support library for making pretty logs.
ANSI / Xterm 256 color library for Dart #
Feel like you're missing some color in your terminal programs? Use AnsiPen to add ANSI color codes to your log messages.
Easy to disable for production, just set
color_disabled = true and all codes will be empty - no re-writing debug messages.
color_disabled is a global variable for all pen colors.
Note: Be mindful of contrasting colors. If you set "bright white" foreground and don't adjust the background, you'll have a bad time with lighter terminals.
Foreground to bright white with default background:
AnsiPen pen = new AnsiPen()..white(bold: true); print(pen("Bright white foreground") + " this text is default fg/bg");
Background as a peach, foreground as white:
AnsiPen pen = new AnsiPen()..white()..rgb(r: 1.0, g: 0.8, b: 0.2); print(pen("White foreground with a peach background"));
