Module text

Expand description

Measuring text in terminal cells: width, truncation with an ellipsis at the end or in the middle, and word wrapping.

Constants§

grapheme_width: Display width of one grapheme cluster.
printable: One line written for a terminal, as the terminal would leave it on screen: what a carriage return wrote over is gone, colour and cursor sequences are taken out, a tab becomes spaces up to the next stop of eight and no other control character is left.
truncate: text cut to at most max cells, ending in … when anything was removed.
truncate_middle: text cut to at most max cells by removing its middle, with … where the middle was.
width: Display width of text in cells.
wrap: Splits text into lines no wider than max cells.
wrap_ranges: Like wrap, but returns byte ranges into text, so styled text can be wrapped and drawn with its styles.
