5.3 Settings specific to Emacs editing mode†

Settings specific to Emacs editing mode can be performed through the hook keymap_emacs_load.

function my/emacs-load-hook {
  # Settings for Emacs editing mode
  ...
}

blehook/eval-after-load keymap_emacs my/emacs-load-hook
# ble-0.3 and before
# ble/array#push _ble_keymap_emacs_load_hook my/emacs-load-hook

5.3.1 Bleopt prompt_emacs_mode_indicator (Prompt string) (v0.4)^†

This option specifies the content of the mode indicator shown in the information line as a prompt sequence.

[ Note: Please specify the following settings through the hook keymap_emacs_load. See the code example at the section beginning. ]

# hook:keymap_emacs_load

# default
bleopt prompt_emacs_mode_indicator='\q{keymap:emacs/mode-indicator}'

5.3.2 Prompt sequence \q{keymap:emacs/mode-indicator} (v0.4)^†
