cmdio: add Width, PadRight, and PadLeft helpers for column alignment#5394
Merged
Conversation
Adds Width, PadRight, and PadLeft to libs/cmdio for aligning columns of colored text. Width returns the visible terminal-cell width, ignoring ANSI color escapes and counting wide glyphs (CJK, emoji, fullwidth Latin) as two cells; the Pad* helpers pad to a visible width, measuring the rendered string so already-colored cells stay aligned. This lets commands print color-per-cell tables without the "measure the uncolored string, pad by hand" dance that misaligns rows on any escape sequence or wide glyph -- something text/tabwriter can't fix, since it counts runes. Implemented via lipgloss.Width, already a direct dependency. Co-authored-by: Isaac

Switch `lakebox list` and `ssh-key list` from mattn/go-runewidth to the cmdio.Width / cmdio.PadRight helpers added in #5394. Because PadRight measures the rendered (already-colored) string, this drops the manual "measure the uncolored cell, color it, then pad by hand" dance that the old code needed to keep ANSI escapes from throwing off alignment. With the only direct runewidth importers gone, demote go-runewidth back to an indirect dependency and drop its NOTICE entry; it remains in the module graph transitively via charmbracelet/x/ansi (which is what cmdio.Width calls through).
