Lightline.vim: Close buffer (X)

[tonylambiris]

How can I configure the (X) in the upper right to close the current buffer? It doesn't seem to response to anything, except when NERDtree is open I can get the status bar to display NERDTree: cannot close tree root

Thanks in advance!

Let me see the result of :set mouse?.

Okay, I figured out what's happening. The X closes the current tab, not the current buffer. Try :tabnew and click the X. Unfortunately we cannot configure the action for the closing mark in Vim.

For neovim users; configure as follows to make it close the buffer.

let g:lightline = {
      \ 'component': {
      \   'close': '%@LightlineCloseBuffer@ X %',
      \ },
      \ }

function! LightlineCloseBuffer(...)
  try
    bdelete
  catch
    echohl ErrorMsg
    echom v:exception
    echohl None
  endtry
endfunction

Note that %@ in tabline is neovim only.

@itchyny Thanks, that's getting me closer. Is there a turn-key setup that will have lightline Just Work(tm) with opening files and closing them from the top bar without any of the religious tabs vs buffers vs windows vs .

Thanks again for your help.

Hmm, it's hard to configure as opening files from tabline in Vim. You may try plugins like CtrlP or use GVim.
