beamtea_textarea (beamtea v0.1.2)

View Source

A bubble: a multi-line text area, mirroring the textarea package in charmbracelet/bubbles.

Full multi-line editing: insertion, newlines, backspace/delete across line boundaries, and caret movement with the arrows and Home/End. The visible window scrolls vertically to keep the caret in view. As with beamtea_textinput, the caret is drawn with reverse video.
