Manual output on enter, no linebreak.

[Shuraken007]

Hello.
I'm sending some arguments to fzf (separated by !) and I want only first argument on output after selecting multiple result and hitting Enter.

So .. I added smth like this.

   export FZF_CTRL_T_OPTS="
   -d!
   --with-nth 2
   --bind \"enter:execute(for e in {+1}; do echo \$e; done)+abort\"
   "

But problem is, that echo \$e don't adding linebreaks, all selected items printed oneline.
As you see, I can't add some postprocess, cause FZF_CTRL_T - havn't such options.

When you press the ⌃ Control + T hotkey, the fzf-file-widget widget is executed, which uses the __fsel function.

fzf/shell/key-bindings.zsh

Lines 63 to 68 in 952b6af

	fzf-file-widget() {
	LBUFFER="${LBUFFER}$(__fsel)"
	local ret=$?
	zle reset-prompt
	return $ret
	}

fzf/shell/key-bindings.zsh

Lines 42 to 56 in 952b6af

	# CTRL-T - Paste the selected file path(s) into the command line
	__fsel() {
	local cmd="${FZF_CTRL_T_COMMAND:-"command find -L . -mindepth 1 \\( -path '*/.*' -o -fstype 'sysfs' -o -fstype 'devfs' -o -fstype 'devtmpfs' -o -fstype 'proc' \\) -prune \
	-o -type f -print \
	-o -type d -print \
	-o -type l -print 2> /dev/null | cut -b3-"}"
	setopt localoptions pipefail no_aliases 2> /dev/null
	local item
	eval "$cmd" | FZF_DEFAULT_OPTS="--height ${FZF_TMUX_HEIGHT:-40%} --reverse --scheme=path --bind=ctrl-z:ignore ${FZF_DEFAULT_OPTS-} ${FZF_CTRL_T_OPTS-}" $(__fzfcmd) -m "$@" | while read item; do
	echo -n "${(q)item} "
	done
	local ret=$?
	echo
	return $ret
	}

The echo -n line outputs the values on the same line. If you would place the __fsel in your .zshrc after sourcing fzf's key-bindings.zsh and remove the -n it would print over multiple lines.

   local item
   eval "$cmd" | FZF_DEFAULT_OPTS="--height ${FZF_TMUX_HEIGHT:-40%} --reverse --scheme=path --bind=ctrl-z:ignore ${FZF_DEFAULT_OPTS-} ${FZF_CTRL_T_OPTS-}" $(__fzfcmd) -m "$@" | while read item; do
-    echo -n "${(q)item} "
+    echo "${(q)item} "
   done
   local ret=$?

Consider using the additional f (temporary file) placeholder expression flag as an alternative to your for loop.

• In this example, the print command, which is specific to zsh, is used to generate a sample input for fzf.
  • If you were using bash, you might use zsh -c 'print …'.

print -C3 {A..I}
# A  D  G
# B  E  H
# C  F  I

• Using the {+2} placeholder flag generates a space-separated list of the selected lines.

print -C3 {A..I} | fzf --sync --bind 'start:select-all+become:echo {+2}'
# D E F

• This placeholder gives you the path to the temporary file where your selected lines are stored {+f2}.

print -C3 {A..I} | fzf --sync --bind 'start:select-all+become:cat {+f2}'
# D
# E
# F

---

Alternatively, you can define a custom widget and assign it to a hotkey to avoid modifying the __fsel function.

# zshrc
test_widget() {
	print -C3 {A..I} | fzf --sync --bind 'start:select-all+become:cat {+f2}'
}
zle -N test_widget
bindkey "^X" test_widget

Thanks a lot.
