My history file looks like:

....
: 1656846180:0;mint-vm
: 1657092275:4;g d fpull
: 1657092331:0;stow-dotfiles
: 1657092447:0;fd --hidden --ignore-file .gitignore
--base-directory="$HOME/.dotfiles/.common-dotfiles-buggy-nemo-bookmarks"
--type l --type f | sd ^. $HOME | xargs -I{} rm {}\

: 1657092530:0;fd --hidden
--base-directory="$HOME/.dotfiles/.common-dotfiles-buggy-nemo-bookmarks"
--type l --type f | sd ^. $HOME | xargs -I{} rm {}\
stow --target="$HOME" --dir="$HOME/.dotfiles" --no-folding --restow
.common-dotfiles-buggy-nemo-bookmarks\

: 1657092737:0;for i in "${array[@]}"\
do\
 \
 DOWNLOAD_URL=$(curl -Lfs ${i} | grep -m1 -Po '(?<=href=")[^"]*zip')\
 FILE_NAME=$(echo $DOWNLOAD_URL | grep -Eo "([^\/]+$)")\
 \
 wget $DOWNLOAD_URL\
 \
\
done

for i in "${array[@]}"\

 DOWNLOAD_URL=$(curl -Lfs ${i} | grep -m1 -Po '(?<=href=")[^"]*zip')\

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?
