I'm using the following configs:

set nocompatible hidden laststatus=2

if !filereadable('/tmp/plug.vim')
  silent !curl --insecure -fLo /tmp/plug.vim
    \ https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
endif

source /tmp/plug.vim
call plug#begin('/tmp/plugged')
Plug 'junegunn/fzf', { 'do': './install --bin' }
Plug 'junegunn/fzf.vim'
call plug#end()

autocmd VimEnter * PlugClean! | PlugUpdate --sync

" Below is what I've added to my configs:
nnoremap <c-p> :Files<cr>
command! -bang -nargs=? -complete=dir Files
  \ call fzf#vim#files(<q-args>, fzf#vim#with_preview('right:50%', 'ctrl-p'), <bang>0)

After invoking Ctrl+p I'm presented with a list of my files with a preview window. However the lines of content in the preview is limited to ~19, when in actuality the files have more lines.

I got same behavior on Mac with vim8, did you find a fix yet @npearson72 ?

[npearson72]

@lan-nguyen91 afraid not.

[lan-nguyen91]

@junegunn, do you happen to know if vim default config hide stuff on preview window, right now the first 30 lines show on my set up, but as I scrolled, it is all blank. :(

[junegunn]

The behavior is intentional and is not configurable: https://github.com/junegunn/fzf.vim/blob/master/bin/preview.sh#L50-L54

For now, I suggest that you fork the repository and change it to your needs since I'm not planning to add more configuration options for the time being.

@junegunn thanks for the direction, @npearson72 I followed June direction, and removed this condition && NR <= $LAST in the line above, i'm not sure it is ideal but works for me right now. Cheers 😀

[npearson72]

Works like a charm. Thanks guys!

Removing && NR <= $LAST from preview.sh file does not seem to work anymore.

I ended up with these changes:

• Commented out this if.

# if [ -z "$FZF_PREVIEW_COMMAND" ] && command -v bat > /dev/null; then
#   bat --style=numbers --color=always --pager=never \
#       --line-range=$FIRST:$LAST --highlight-line=$CENTER "$FILE"
#   exit $?
# fi

• Add bat back.

DEFAULT_COMMAND="bat --style=numbers --color=always {} || highlight -O ansi -l {} || coderay {} || rougify {} || cat {}"
CMD=${FZF_PREVIEW_COMMAND:-$DEFAULT_COMMAND}
CMD=${CMD//{\}/$(printf %q "$FILE")}

• Remove && NR <= $LAST like it was mentioned before.

eval "$CMD" 2> /dev/null | awk "NR >= $FIRST { \
    if (NR == $CENTER) \
        { gsub(/\x1b[[0-9;]*m/, \"&$REVERSE\"); printf(\"$REVERSE%s\n$RESET\", \$0); } \
    else printf(\"$RESET%s\n\", \$0); \
    }"

How do you scroll the preview pane? 🤔

Easiest way for me to hack around this was to set

FIRST=0
LAST=1000000

@junegunn Why do we limit the file preview?

[Rodrigo-Barros]

How do you scroll the preview pane? thinking

Just use shift + down or shift +up,
mouse scroll works too.

[her]

@Rodrigo-Barros the content is not all there though, it's cut off. Preview a large file and scroll, you'll see you only have a small subsection of the file, rather than all the contents.

@ogirginc @Rodrigo-Barros

Do any of you know how I can keep the highlighted line in the preview in the middle by default. Right now, it always shows 5 lines above the highlighted line, which isn't helpful to get context before the highlighted line. #1092 has a screenshot with an example.

Another question for you guys, I saw that Shift + Up/Down works great with scrolling, is it possible to rebind those keys ? Arrow keys are harder to reach (Would prefer something like Ctrl -j/k).

Looking forward to hearing from you. Thanks in advance.

[Rodrigo-Barros]

@123subhadeep you can install bat it's an optional dependency that enables syntax highlight.
you can add this line on your .vimrc to rebind your keys:
let $FZF_DEFAULT_OPTS='--bind=ctrl-j:preview-down,ctrl-k:preview-up'

This info available on manual.

I don't know if there another way to rebind your keys.
