None if we're on the new buffer, else the index of history

Deletes every character preceding the cursor until the beginning of the line.

The default for `Context.word_divider_fn`.

Go through the history and try to find a buffer which starts the same as the new buffer given to this function as argument.

XXX rename, too confusing

Get the current count or the number of remaining chars in the buffer.

Moves to the end of history (ie. the new buffer).

Moves to the start of history (ie. the earliest history entry).

Takes other buffer, measures its length and prints this buffer from the point where the other stopped. Used to implement autosuggestions.

Creates an `Editor` and feeds it keypresses from stdin until the line is entered. The output is stdout. The returned line has the newline removed. Bef

Same as `Context.read_line()`, but passes the provided initial buffer to the editor. ```no_run use liner::Context; let mut context = Context::new();

Set maximal number of entries in history file

Set maximal number of buffers stored in memory

Attempts to undo an action on the current buffer. Returns `Ok(true)` if an action was undone. Returns `Ok(false)` if there was no action to undo.

make sure we only attempt to repeat for as many chars are in the buffer

ctrl-c should generate an error

when the current buffer is empty, ctrl-d generates and eof error

when the current buffer is not empty, ctrl-d should be ignored

ctrl-h should act as backspace
