I have been trying out FZF with Neovim. I installed it via a nvim plugin package manager. I have not installed it for the command line.
When trying to see file previews :FZF --preview="head -$LINES {}"
I get the following error: Unknown option $LINES.
It seems that Zshell doesn't like anything I add between the double-quotes e.g.: head -n 10 and will throw an error.
Is this possible from Vim without the FZF command line?
Thanks in advance for your time and help.
I don't have $LINES defined in my Vim environment, and I'm using Zsh, so it's probably not exported to child processes. However, to make this work you need to remove quotes and escape spaces:
:FZF --preview=head\ -10\ {}
Making $LINES working is more tricky, for basic you could probably add export LINES to your .zshrc, but this won't handle situations, when you resize your terminal window, exported value will still be on the original value. Also, preview window is much smaller than terminal, so this will still be truncated to the size of the preview window.
fzf.vim depends on the basic Vim plugin of the main fzf repository, which means you need to set up both "fzf" and "fzf.vim" on Vim.So I never used fzf but I think you won't do much if you don't have fzf installed. Also how did you defined$LINES?FZFis a command from basic fzf Vim plugin, not thefzf.vimextension plugin
