Module: Tuile::Ansi

Defined in:
lib/tuile/ansi.rb,
sig/tuile.rbs

Overview

ANSI escape sequence constants. Tuile emits colors and text attributes via StyledString / Color, which produce SGR sequences ("Select Graphic Rendition", ESC [ <params> m — e.g. \e[31m red, \e[1m bold, \e[0m reset). Host apps may also use Rainbow, which emits the same form.

RESET =

SGR reset (ESC [ 0 m). Restores the terminal's default foreground, background, and text attributes.

Returns:

  • (String) 
"\e[0m"
SYNC_BEGIN =

Begin Synchronized Update (DEC private mode 2026, "Synchronized Output"). The terminal stops refreshing its display and buffers every subsequent write until SYNC_END, then composites the whole batch atomically — so a multi-cell repaint is never shown half-drawn. This is what stops flicker when a frame redraws a large region (e.g. the full-scene repaint a shrinking popup forces). Terminals without support ignore the private-mode set, so it's a safe no-op there. Screen#repaint wraps its single frame-buffer flush in this pair.

Returns:

  • (String) 
"\e[?2026h"
SYNC_END =

End Synchronized Update — see SYNC_BEGIN. Releases the buffered frame and lets the terminal repaint.

Returns:

  • (String) 
"\e[?2026l"
