Struct Line 

pub struct Line { /* private fields */ }

Implementations

impl Line

pub fn text(&self) -> String

pub fn is_empty(&self) -> bool

pub fn mode(&self) -> Mode

pub fn cursor(&self) -> usize

cursor position as a char index, for drawing the block.

pub fn pending(&self) -> String

the pending command, echoed in the footer the way vi shows one.

pub fn accept(&mut self) -> String

accept the line: record it in history and start a fresh one in insert mode, the way hitting enter in any chat client does.

pub fn history(&self) -> &[String]

sent lines, oldest first — what the face persists.

pub fn history_rev(&self) -> u32

changes every time accept records a line.

pub fn set_history(&mut self, lines: impl IntoIterator<Item = String>)

seed history from disk: blanks and repeats dropped, only the newest HISTORY_CAP kept.

pub fn reset(&mut self)

throw the draft away and return to insert mode.

pub fn focus(&mut self)

entering the composer always starts in insert mode — you came here to type, and the draft you left behind is still there.

pub fn replace_range(&mut self, lo: usize, hi: usize, s: &str)

replace lo..hi (char indices) with s, leaving the cursor after the inserted text. undoable. this is the completion hook: tab swaps the word under the cursor for a candidate without the editor knowing why.

pub fn key(&mut self, k: KeyEvent) -> Act
