I use Vim for editing DocBook files. I created several functions that manipulate the text in the buffer. For example to build a PDF from the source using an external command. I run these functions asynchronously in a separate Vim terminal buffer. I need to capture the last line of the terminal buffer after the build PDF process finishes because it is the path to the target PDF file. The process is following:

let term_buf_no = s:RunCmdTerm(cmd, 'term_name', 'exit_cb')

The above command runs s:RunCmdTerm function and passes the cmd which is the actual command to be run (building PDF) + a callback function exit_cb

the RunCmdTerm function runs cmd in a terminal buffer like this:

let term_buf_no = term_start(cmd, {'term_name': name, 'term_rows': 10, 'exit_cb': exit_cb})

Everything works fine, but when I want to capture the last line of the terminal buffer inside the exit_cb function with:

let target_dir = getbufline(term_buf_no, '$')[0]

it captures earlier lines from the output but never the last one.

Any ideas?

    Do you really need a terminal? If you just want to run the command to extract the last line, you can use systemlist()

The term_wait(150) function before reading the last line of the terminal buffer output solved it :-)

    Maybe could you post a very light version of the entire solution such that the problem and its solution could be reproduced? Jan 27 at 15:50
  • So you were calling exit_cb before the terminal process finish?
