How can I run a terminal command (for instance build) in vim while working on a file, while simultaneously showing the output live in a vsplit?

  • Have a look at github.com/tpope/vim-dispatch – taketwo Dec 7 at 8:14
  • thanks, ill have a look at it, I just thought I heard vim now supports asynchronous tasks by default – user2741831 Dec 7 at 8:17
  • Yes it does, @philosopher.stoned gave an example. The plugin just wraps around this functionality (and provides fallback for old Vim versions). In my opinion it has a nice interface and is easier to use than raw Vim commands. – taketwo Dec 8 at 9:12
  • dokes this also work in gvim? cuz it says I need tmux – user2741831 Dec 8 at 14:32

You need to use job_start function for this. It'll invoke your command in a separate process instance. You can pass buffer names to this call and vim will link STDOUT and STDERR pipes of job's process to these buffers. A host of additional actions are also possible, like registering callbacks when data is posted to these buffers, type of job being run, etc.

Example:
        let logjob = job_start("tail -f /tmp/log",
                             \ {'out_io': 'buffer', 'out_name': 'dummy'})
        vsplit | buffer dummy
  • this works really well, thanks. Is there a way to always keep the buffer at the very end to always see the output – user2741831 Dec 8 at 21:15
  • Use vim movement command 'G' to go to end of buffer. Once at end, it'll always track new data being added and scroll automatically. – philosopher.stoned 2 days ago
