How to change the Rg preview window color scheme?

[gor-bit]

• [x] I have fzf 0.23.0 or above
• [x] I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md
• [x] I have read through https://github.com/junegunn/fzf/blob/master/README-VIM.md
• [x] I have read through the manual page of fzf (man fzf)
• [x] I have searched through the existing issues

On my terminal (iTerm2), the current color scheme of the default Rg preview window currently makes the line numbers very difficult to read. The screenshot below shows what this looks like using the Vim minimal configuration.

I'd like to update the Rg preview window (I believe it uses bat) to use the base64 color scheme.

i.e. Set bat --theme=base16 instead of the current bat.

How can I update the vim plugin to do this? I can't find where bat is called anywhere within the code.

Thanks!

Add '--preview', 'bat --some_bat_parameter' to the fzf#vim#grep options. fzf_opt_rg in the example below:

command! -bang -nargs=* Rg call fzf#vim#grep(fzf_cmd_rg .shellescape(<q-args>), 1, fzf#vim#with_preview({'options': fzf_opt_rg}), <bang>0)

Put export BAT_THEME=base16 in your shell configuration file or let $BAT_THEME = 'base16' in your Vim configuration file.
