Function get_readline_edit_mode

Source 
pub fn get_readline_edit_mode(contents: impl AsRef<[u8]>) -> Option<EditMode>
Expand description

Parse readline editing mode from the given byte content, which should be the contents of an inputrc config file.

See rl_read_init_file for how to retrieve the contents of the effective inputrc file.

This function looks for the editing-mode variable in the given inputrc bytes. Per the [manual, section 8.3.1]:

editing-mode

The editing-mode variable controls which default set of key bindings is used. By default, Readline starts up in Emacs editing mode, where the keystrokes are most similar to Emacs. This variable can be set to either ‘emacs’ or ‘vi’.

§Examples

use artichoke_readline::{get_readline_edit_mode, EditMode};

const INPUTRC: &str = "
set editing-mode vi
";

assert_eq!(get_readline_edit_mode(INPUTRC), Some(EditMode::Vi));

§Implementation Notes

This parser does not support GNU Readline’s conditional init constructs (the $if construct).
