yuki-yano / fern-preview.vim Goto Github PK

This plugin looks great and is very useful in vim. However, I can't get it to work in neovim.
When I try to use it the pop-up window does open, but it is completely blank, except for the "1" to show the line number in the top left-hand corner, like a new empty buffer.

I have the following in my vimrc:

"make fern preview window 50% width
function! fern_preview#width_default_func() abort
  let width = float2nr(&columns * 0.5)
  return width
endfunction

It does not work in neovim with or without this, however, it does give an error message with this, which might be a clue.
E746: Function name does not match script file name: fern_preview#width_default_func

Thanks for the great set of Plugins. I have this piece of config as suggested in the readme:

function! s:fern_settings() abort
  ....
  nmap <silent> <buffer> <C-d> <Plug>(fern-action-preview:scroll:down:half)
  nmap <silent> <buffer> <C-u> <Plug>(fern-action-preview:scroll:up:half)
endfunction

I use <C-d> and <C-u> in the fern itself to jump up and down the list of directories/files as well, but setting it here causes the fern/vim to throw an error:

Error detected while processing function fern_preview#half_down[2]..<SNR>187_info:
line    3:
E716: Key not present in Dictionary: "width,   'height': l:info.height,   'topline': l:info.firstline }"

Is there a way to only map those keys when a preview window is open, and do the regular <C-d>, <C-u> when there's no preview window?

Is there exist api support modify the size of preview window without changing the source code?

Dear yuki, just tried out your work today and i think it's fantastic!

just thought ill mention that the offsets might be off or something, or my settings aren't right.

You can view a screenshot here:

As you can see, the preview window eats up the actual menu itself on the left.

Do you think theres's setting somewhere that i could use to fix this?

Apart from having

Plug 'yuki-yano/fern-preview.vim

in my .vimrc file, i have nothing in it. Perhaps you can advise? Thank you :)
