OpenTUI 0.5.8

2026-08-24npmGitHub release

Added

• core: Adds "unicode-wide" to WidthMethod. It uses the width profile of Ghostty 1.3, which renders certain multi-code-point graphemes two columns wide, so rendering, wrapping, and cursor placement stay aligned with the terminal. See Text and terminal cells. (#1415)

Fixed

• core: Keeps the left-button selection state until the left button is released, so a right-click does not interrupt a drag. See Interaction, focus, and selection. (#1416)
• core: Counts Thai spacing marks, such as SARA AM, in grapheme widths, so output coordinates match the terminal. See Text and terminal cells. (#1413)
