The context
I have mapped <c-p> in terminal mode so that it deletes the terminal buffer where the cursor is. The way I've created this mapping is presented below
tnoremap <c-p> <c-w>:bd!<CR>
This mapping works when opening a terminal (by executing :term) or when executing :term {command} and when the {command} is still being executed.
If the job is finished, pressing <c-p> does not execute the mapped command.
Because of this, I had to find a way to create that same effect taking into consideration that mappings created with the :tmap command don't work when the job on a terminal buffer is finished.
I first thought in this command (see below), but I don't want <c-p> to be mapped in normal mode (this is explained by the fact that my main goal was to only create it for terminal buffers through the tmap command. Otherwise I wouldn't have post this question.)
nnoremap <c-p> <c-w>:bd!<CR>
Since I dont wan't this mapping to be created for all buffers, I tried to accomplish that with this command (whose idea was retrieved from this question).
au BufWinEnter * if &buftype == 'terminal' | nnoremap <buffer> <c-p> <c-w>:bd!<CR> | endif
However, pressing <c-p> didn't result in anything. I tried to troubleshot this and found out that the BufWinEnter is not the appropiate autocommand event, since it seems that when the :term {command} is executed, that autocmd is triggered but at that time the &buftype variable is not yet set.
The question
How can I map <c-p> so that it executes <c-w>:bd!<cr> on those buffers that were opened with the :term {command} and whose job is already finished, without making <c-p> to be always mapped?
Note that this would be accomplished if we were to find an appropiate autocommand event which is triggered when the &buftype variable is already set because thus this mapping would work and wouldn't make <c-p> to be always mapped to that command.
au BufWinEnter * if &buftype == 'terminal' | nnoremap <buffer> <c-p> <c-w>:bd!<CR> | endif
Additional information
The following minimal vimrc might help you to troubleshot this problem
set nocompatible
fun! P()
echom '&buftype is: "' . &buftype . '"'
endfun
" Execute `:term ls` and you will see that the echoed message prints an empty
" `&buftype`.
autocmd BufWinEnter * call P()
" Try pressing this on a terminal whose job is finished (open one " with `:term
" ls`). You will notice that it doesn't execute the mapped command.
tnoremap <c-p> <c-w>:bd!<cr>
