possibility to do bdelete in FzfPreviewBuffers about fzf-preview.vim

[yuki-yano]

In the example we created a new command, but you can also add a new mapping for FzfPreviewBuffers.
By default, the following settings are made for the processor.

let default = {
\ '':       function('fzf_preview#resource_processor#edit'),
\ 'ctrl-x': function('fzf_preview#resource_processor#split'),
\ 'ctrl-v': function('fzf_preview#resource_processor#vsplit'),
\ 'ctrl-t': function('fzf_preview#resource_processor#vsplit'),
\ 'ctrl-q': function('fzf_preview#resource_processor#export_quickfix'),
\ }

Therefore, after passing the created processor to set_processor_once,
Start FzfPreviewBuffers and change the mapping.

Example

function! s:buffers_delete_from_paths(paths) abort
  for path in a:paths
    execute 'bdelete! ' . path
  endfor
endfunction

let g:buffer_delete_processor = {
\ '':       function('fzf_preview#resource_processor#edit'),
\ 'ctrl-s': function('fzf_preview#resource_processor#split'),
\ 'ctrl-v': function('fzf_preview#resource_processor#vsplit'),
\ 'ctrl-t': function('fzf_preview#resource_processor#vsplit'),
\ 'ctrl-q': function('fzf_preview#resource_processor#export_quickfix'),
\ 'ctrl-x': function('s:buffers_delete_from_paths'),
\ }

nnoremap <silent> <Leader>b :<C-u>call fzf_preview#resource_processor#set_processor_once(g:buffer_delete_processor)<CR>:FzfPreviewBuffers<CR>

I checked the :CocCommand fzf-preview.Buffers with the following settings, and I'm able to remove the buffer without any problems.

call plug#begin('~/.vim/plugged')
Plug 'junegunn/fzf'
Plug 'neoclide/coc.nvim', {'branch': 'release'}
Plug 'ryanoasis/vim-devicons'
call plug#end()

let g:coc_global_extensions = ['coc-fzf-preview']

Thank you.
I would consider adding features.

[yuki-yano]

I am considering adding an opener(processor?) to determine how to handle the selected resource.
Since it will be possible to pass the process to be performed to the resource selected from the outside, I think that it can be realized by deleting the buffer there.

[yuki-yano]

Processing can be passed by merging #52.
For example, if you want to do bdelete, you can write like this.

function! s:buffers_delete_from_paths(paths) abort
  for path in a:paths
    execute 'bdelete! ' . path
  endfor
endfunction

function! s:fzf_preview_buffer_delete() abort
  call fzf_preview#resource_processor#set_processor_once({'': function('<SID>buffers_delete_from_paths')})
  FzfPreviewBuffers
endfunction
command! FzfPreviewBufferDelete call s:fzf_preview_buffer_delete()

How about that? @rlisowski

I'm new to fzf-preview but interested in closing buffers as well. One question about the solution: with the current implementation one has to call a different function FzfPreviewBufferDelete do be able to delete the buffer? I think it would be way more convenient if one could delete buffers out of the "normal" FzfPreviewBuffer list by using a shortcut (like C-x opens the selected file in a new split)

[yuki-yano]

I changed the concept, you can pass processor as an argument when running the command.

An example looks like this.

function! s:buffers_delete_from_paths(paths) abort
  for path in a:paths
    execute 'bdelete! ' . path
  endfor
endfunction

let g:fzf_preview_buffer_delete_processors = fzf_preview#resource_processor#get_default_processors()
let g:fzf_preview_buffer_delete_processors['ctrl-x'] = function('s:buffers_delete_from_paths')
nnoremap <silent> <Leader>b :<C-u>FzfPreviewBuffers -processors=g:fzf_preview_buffer_delete_processors<CR>

Fixed

Tested it and it works pretty well, thanks a lot for the super fast response and the fix.
Just in case anyone else is interested in this: be sure to use a different "buffer closing" command (like :Bdelete from https://github.com/moll/vim-bbye) then the default :bdelete. Otherwise your entire session will be closed if the buffer is currently open when you try to close it.

[rlisowski]

Works perfect. Thanks.

Sorry for re commenting here but does this still work with the new coc version of fzf preview? I tried <C-q> as suggested in the Readme but this puts the buffer to the quickfix window. I'd like to call FzfPreviewBuffers and then close some of the listed buffers there with a shortcut.

[tuxflo]

Thanks for the quick response!
let g:coc_global_extensions = ['coc-fzf-preview']
This line was missing in my config and now it works as expected!
