tui

Terminal UI composition for Ecko: width-aware pad/center/truncate, bordered boxes, and aligned tables over std.term.

import tui

Pure computation: it declares no capabilities, so it cannot touch the network, the filesystem or the environment.

Version 0.9.5 - source - MIT.

pad_end(s, w)

Pad s on the right (left) to a visible width of w; wider stays unchanged.

pad_start(s, w)

Right-align s in w columns by padding on the left. Width is measured in visible columns, so ANSI colour codes do not count.

center(s, w)

Center s in w columns; an odd leftover goes on the right.

truncate(s, w)

Truncate to a visible width of w, marking the cut with an ellipsis. (A truncated colored string loses its trailing escapes - truncate plain text.)

box(lines, opts)

box(lines, opts?) -> a bordered box as one string. opts: border (style), title, padding (spaces inside the verticals, default 1), min_width (total).

table(rows, opts)

Render rows as an aligned text table. opts may carry align (a list of "left"/"right" per column) and gap (the column separator, two spaces by default). Column widths come from the widest visible cell.
