I recorded info of terminal buffers in a dict, and want remove bufnr of closed ones.

Can you tell me how to start a terminal such that call a function on exit, eg,

func! myterm#remove(bufnr):
    call remove(s:terms, a:bufnr)
endfunc

  • you probably need to use term_start() and use the callback options for this specific use case. Nov 27 '19 at 11:38

The solution is using job-exit_cb handler, (see :help job-exit_cb)

A working example is

func! g:Exit_cb(job, exit_code)
    echo term_getjob(2)
    let pid = matchstr(a:job, '^\%(process \)\zs\d\+')
    echom "job " . pid . " finished with exit_code " . a:exit_code
endfunc

call term_start('bash', {'exit_cb': function('g:Exit_cb')})

Run above code, then close the newly created terminal, you will see something like below

job 61392 finished with exit_code 0

be echoed at the bottom, you can also verify with :mess command. (since `:echom is used)
