Expand multiple items, manipulating each item first

[rieje]

I'm implementing ctrl-d to trash items:

selection=$(fd . "$HOME/.config/alacritty/themes/" --format '{/}' |
  sed 's/.toml$//' | SHELL=/usr/bin/bash fzf \
  --header "original theme: $theme" \
  --preview='set_theme {}' \
  --bind "ctrl-d:execute-silent(trash "$alacritty_theme_dir/{+}.toml")")

example of items: aura, breeze, dracula (names of themes). When selected, I want to trash them as ~/.config/alacritty/themes/<theme>.toml. When these names of themes are selected, can they be manipulated to be their actual paths then trashed?

With {+} as in above, it will expand into something like trash "$alacritty_theme_dir/'aura' 'breeze' 'dracula'.toml"

Any ideas?

Much appreciated.

You could try to take advantage of fd's --format flag by adding the listed values twice: once as {/.}, the basename without the file extension, and once as {}, the normal path, separated by a character you like. In the example below, the Record separator \x1e^{1 2} is used.

Then, pipe the output into fzf, set the delimiter to your chosen character, and control what is displayed with --with-nth. After this, you can use {1} or {2} to perform the desired action.

fd -a --format $'{/.}\x1e{}' | fzf --delimiter '\x1e' --with-nth 1 --preview 'echo {+2}'

Works nicely. I am having an unrelated problem with reloading:

if selection=$(fd -a . "$HOME/.config/alacritty/themes/" --format $'{/.}\x1e{}' |
  SHELL=/usr/bin/bash fzf \
  --delimiter '\x1e' --with-nth 1 \
  --header "original theme: $theme" \
  --preview='set_theme {+2}' \
  --bind "ctrl-d:execute-silent(trash '{+2}')+reload(fd -a . "$HOME/.config/alacritty/themes/" --format $'{/.}\x1e{}')"); then
  set_theme permanent "${selection##*$'\x1e'}"
else
  set_theme "$alacritty_theme_dir/$theme.toml"
fi

When I ctrl-d, it trashes the file as expected but also appears to apply set_theme. My intention is to just trash the file and re-run fd/fzf to update the list and continue previewing and potentially ctrl-d to trash again.

Any ideas?

Thanks.

I guess the issue here is proper quoting and escaping '{}' as it's special when 'fzf' sees it.

Try assigning your command to a variable, like this.

fd_command=$'fd -a . $HOME/.config --format {/.}\x1e\\{}'
fzf \
  --bind "start:reload:$fd_command" \
  --bind "ctrl-d:execute(echo hi)+reload:$fd_command" \
  --delimiter '\x1e' \
  --preview 'echo {2}' \
  --with-nth 1

PS: this will also be executed --preview='set_theme {+2}', make sure its intentional
