Module wrap 

Row counting for the input TextArea.

ratatui_textarea::TextArea does not expose how many on-screen rows its content occupies, so counting them requires the very wrapping algorithm the widget renders with. The functions in this module are a simplified copy of wrap.rs from ratatui-textarea v0.9.2 (MIT), dropping the line-number gutter and tab-stop width logic, and the actual range handling (we only need a number of lines as the result).

Functions

display_width 🔒

Total display width of the given text.

split_range_by_grapheme_width 🔒

Wraps the given byte range of a line at grapheme boundaries, accounting for wide characters.

wrap_word_chunks 🔒

Wraps the given line at word boundaries, falling back to grapheme splitting for words wider than the width when enabled.

wrapped_line_count 🔒

How many lines need to be rendered for the given mode, at least 1.
