Text & layout
Utilities for measuring and shaping text that respect ANSI escape codes and double-wide characters — so your layouts line up no matter what's in the string.
Word wrap
dart
const Style(
wordWrap: true,
width: 40,
border: Border.rounded,
borderTitle: ' Notes ',
).render(longText);Measuring & truncating
These helpers count visible terminal columns, stripping ANSI codes and accounting for wide glyphs:
dart
getWidth('hello') // → 5 (visible columns)
getWidth('\x1b[31mhi\x1b[0m') // → 2 (ANSI stripped)
getHeight('line1\nline2') // → 2
truncate('hello world', 5) // → 'hello' (drop right)
truncateLeft('hello world', 5) // → 'world' (drop left)Tab width & margin background
dart
const Style(tabWidth: 4) // expand \t to 4 spaces
const Style(marginBackground: RgbColor(30, 30, 46)) // tint the margin area
