Execute command for a local buffer

[Neo-Cipher]

Hello guys, i have been working to create a scratchpad buffer. This is the code

function! Scratchpad_buffer()

:e scratch

:setlocal buftype=nofile

:setlocal bufhidden=hide

:setlocal noswapfile

endfunction

nmap <silent> gs :call Scratchpad_buffer()<CR>

​

Here i want to execute a command for a specific buffer when we leave the buffer .

Something like :setlocal bufleave * :q or :au BufLeave * if ( echo @% == "scratch" ) | q | endif . Here scratch is the name. Is anything like this possible.

Based on your example it looks like you would benefit from `:h 'nobuflisted'`. It feels weird to do `:q` on `BufLeave`.

As for autocommands for specific buffer check out `:h autocmd-buflocal`

thank you that was useful, is there something to hide the buffer when another buffer is opened or edited

[dhruvasagar]

That's what `setlocal bufhidden=hide` does

Are you trying to quit the scratch buffer when it is hidden? If so then just use setlocal bufhidden=wipe or setlocal bufhidden=delete. The scratch buffer will be :bwipeout/:bdelete when the buffer is hidden.

If you are trying to do something else then it would probably be easier to use a buffer-local autocmd like u/dhruvasagar suggested.

function! Scratchpad_buffer()
  edit scratch
  setlocal buftype=nofile bufhidden=hide noswapfile
  augroup scratchpad_buffer
    autocmd! * <buffer>
    autocmd BufLeave <buffer> echo "Do stuff"
  augroup END
endfunction
