Re: How to parse zsh history

The way fzf do it is

....

fzf-history-widget() {
local selected num
setopt localoptions noglobsubst noposixbuiltins pipefail no_aliases 2> /dev/null
selected=( $(fc -rl 1 | perl -ne 'print if !$seen{(/^\s*[0-9]+\**\s+(.*)/, $1)}++' |
FZF_DEFAULT_OPTS="--height ${FZF_TMUX_HEIGHT:-40%} $FZF_DEFAULT_OPTS -n2..,.. --tiebreak=index --bind=ctrl-r:toggle-sort,ctrl-z:ignore $FZF_CTRL_R_OPTS --query=${(qqq)LBUFFER} +m" $(__fzfcmd)) )
local ret=$?
if [ -n "$selected" ]; then
num=$selected[1]
if [ -n "$num" ]; then
zle vi-fetch-history -n $num
fi
fi
zle reset-prompt
return $ret
}
zle -N fzf-history-widget
bindkey -M emacs '^R' fzf-history-widget
bindkey -M vicmd '^R' fzf-history-widget
bindkey -M viins '^R' fzf-history-widget
....

but I want to do it with skim instead of fzf.

I am working on a widget for fuzzy search history.

....
skim-history() {
origquery=${BUFFER}
output=$(history -1 1 | sd '^[ ]*[0-9]*[ ]*' '' | sk --tac --no-sort --exact)

if [ $? -eq 0 ]; then
BUFFER=$output
else
BUFFER=$origquery
fi

CURSOR=$#BUFFER
}

zle -N skim-history
bindkey '^R' skim-history
....

In `history -1 1 | sd '^[ ]*[0-9]*[ ]*' '' | sk --tac --no-sort --exact`, sd is used instead of sed, which just removes numbers from the beginning. However, it messes things up if the command is multi-line.

What I found is, the only way zsh history parsing works correctly is if I use something like !NUM, to get the history. How can I edit my zle extension to do that?

Another option is (if previous fails), do not save multi line commands in history. How can I do that?
