Widget khusus history-incremental-multi-search
untukzsh
Mendirikan
Buat direktori dan sertakan di Anda. $fpath
Misalnya, saya buat direktori ~/.zsh/functions
, dan baris fpath=($HOME/.zsh/functions $fpath)
di .zshrc
.
Masukkan yang berikut ini dalam file bernama history-incremental-multi-search
di direktori itu.
emulate -L zsh
setopt extended_glob
local oldbuffer=$BUFFER
local -i oldcursor=$CURSOR
local dir # search direction
local chars # input buffer
local -a words # search terms
local -a found # all history items that match first term
local -i hindex=$HISTNO # current
local -i lmatch # last matched history item (for prev/next)
if [[ $WIDGET == *forward* ]]; then
dir=fwd
else
dir=bck
fi
function find-next {
# split the input buffer on spaces to get search terms
words=(${(s: :)chars})
# if we have at least one search term
if (( $#words )); then
# get all keys of history items that match the first
found=(${(k)history[(R)*$words[1]*]})
if (( $#found )); then
# search in widget direction by default
# but accept exception in $1 for "prev match"
search-${1:-$dir}

Masukkan ini atau sumberkan dari .zshrc
:
autoload -U history-incremental-multi-search
# make new widgets from function
zle -N history-incremental-multi-search-backward history-incremental-multi-search
zle -N history-incremental-multi-search-forward history-incremental-multi-search
# bind the widgets to keys
bindkey '^Xr' history-incremental-multi-search-backward
bindkey '^Xs' history-incremental-multi-search-forward
Menggunakan
Sekarang Anda harus dapat memulai pencarian tambahan mundur dengan Ctrl+X, r, maju dengan Ctrl+X, s.
Ketik istilah pencarian Anda dipisahkan dengan spasi. Kunci-kunci berikut tersedia untuk mengendalikannya:
← Backspace: menghapus karakter
Ctrl+W: hapus kata
Ctrl+U: kill line
Ctrl+N: pertandingan selanjutnya
Ctrl+P: pertandingan sebelumnya
Ctrl+G/ Esc: batalkan pencarian
Enter: terima
Solusi ini mungkin dapat disederhanakan sedikit. Ini lebih merupakan bukti konsep fungsional, dengan banyak ruang untuk perbaikan.
