Using Atuin as fzf-history widget doesn't work when pressing enter

[lime-desu]

I've replaced the original fzf-history widget to use atuin instead, from fc -rl 1 command to atuin history list --cmd-only | tac
Here's what the snippets looks like

fzf-history-widget() {
  local selected num
  setopt localoptions noglobsubst noposixbuiltins pipefail no_aliases 2> /dev/null
- selected=( $(fc -rl 1 | awk '{ cmd=$0; sub(/^[ \t]*[0-9]+\**[ \t]+/, "", cmd); if (!seen[cmd]++) print $0 }' |
+ selected=( $(atuin history list --cmd-only | tac | awk '{ cmd=$0; sub(/^[ \t]*[0-9]+\**[ \t]+/, "", cmd); if (!seen[cmd]++) print $0 }' | bat --color=always --wrap never --language=sh --style=plain | 
    FZF_DEFAULT_OPTS="--height ${FZF_TMUX_HEIGHT:-40%} ${FZF_DEFAULT_OPTS-} -n2..,.. --scheme=history --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

Now upon modifying , I'm experiencing a minor issue the same issue as stated on #2924

• Pressing Ctrl-R will show the history widget.
• But pressing Enter will do nothing (the selected history doesn't get accepted)

fzf-history-widget() {
  local selected num
  setopt localoptions noglobsubst noposixbuiltins pipefail no_aliases 2> /dev/null
  selected=( $(atuin history list --cmd-only | tac | awk '{ cmd=$0; sub(/^[ \t]*[0-9]+\**[ \t]+/, "", cmd); if (!seen[cmd]++) print $0 }' | bat --color=always --wrap never --language=sh --style=plain | 
    FZF_DEFAULT_OPTS="--height ${FZF_TMUX_HEIGHT:-40%} ${FZF_DEFAULT_OPTS-} -n2..,.. --scheme=history --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 -U "$selected"
+ zle kill-buffer
  zle reset-prompt
  return $ret
}
zle      -N       fzf-history-widget
bindkey '^R'      fzf-history-widget

This fixed my issue by adding zle -U
and zle kill-buffer
I don't know a thing about zle but according to it's documentation:

-U string

This pushes the characters in the string onto the input stack of ZLE. After the widget currently executed finishes ZLE will behave as if the characters in the string were typed by the user.

As ZLE uses a stack, if this option is used repeatedly the last string pushed onto the stack will be processed first. However, the characters in each string will be processed in the order in which they appear in the string.

kill-buffer (^X^K) (unbound) (unbound)

Kill the entire buffer.
