bleopt prompt_rps1='\X'
#bleopt prompt_rps1_transient=1
エイリアスや関数と比べて、静的略語展開を使うと履歴に実際に実施されたコマンドが
残るので便利です。特に自動補完候補に具体的なコマンドが表示されるので、文脈に依
存するコマンドなどを事前に確認できます。一つの不便な点は、静的略語が文末にある
時、そのまま RET でコマンドを実行すると展開されないことです。設定
bleopt edit_magic_accept
を用いると、コマンド実行時に静的略語展開を実行させることができます。
# blerc
bleopt edit_magic_accept=sabbrev:verify-syntax
また、自分で編集関数を定義して明示的に RET で静的略語展開を実行する ことができます。
# blerc
function ble/widget/my/magic-space-auto-appender {
_ble_edit_ind=${#_ble_edit_str} ble/widget/sabbrev-expand; local ext=$?
((_ble_edit_ind>${#_ble_edit_str})) && _ble_edit_ind=${#_ble_edit_str}
((ext==0)) && ble/widget/"$@"
}
# [C-m] および [RET] が既定の束縛設定の場合

ble-bind -m 'vi_imap' -f 'RET' 'my/magic-space-auto-appender accept-single-line-or-newline'
ble-bind -m 'vi_nmap' -f 'C-m' 'my/magic-space-auto-appender accept-single-line-or vi-command/forward-first-non-space'
ble-bind -m 'vi_nmap' -f 'RET' 'my/magic-space-auto-appender accept-single-line-or vi-command/forward-first-non-space'
