ProjectGrep unreadable with light themes

[NicolaiRuckel]

When using :FzfPreviewProjectGrep with a light theme the text is barely readable (see screenshot).
Manually editing bin/preview_fzf_grep to use another colorscheme fixes that issue. Maybe a global theme option for using bat would be nice.

@NicolaiRuckel you can also do :let g:fzf_preview_command = 'bat --color=always --style=grid --theme=GitHub {-1}', as stated in the readme. Sub GitHub with any light theme of your choice.

Thank you for your suggestion. I did this but for FzfPreviewProjectGrep the corresponding option is let g:fzf_preview_grep_preview_cmd and its default value is expand('<sfile>:h:h') . '/bin/preview_fzf_grep'. I tried to replace it with bat but this gives some errors.

Hmm, right. Guess we'll need to wait for a fix then ;)

Maybe the base16 theme would be a more sensible default?
See sharkdp/bat#490

Actually, it doesn’t work even if you set your terminal colors in nvim.

One workaround is to copy and rewrite the preview script to an executable location.
Set the path to g:fzf_preview_grep_preview_cmd and preview with the modified script.

I may remove the theme specification from the preview script.
In that case, you can use any theme by setting the BAT_THEME environment variable.
let $BAT_THEME = 'GitHub'

That is actually a very good suggestion. I’ll do that. Thank you very much. :)
