Create new runner when invalid

[laktak]

I have a similar problem as #62 - When I manually close the runner and issue :VtrSendLinesToRunner I'd like it to just reopen a new runner instead of complaining with

VTR: Runner pane setting (1) is invalid. Please reattach.

Is that possible?

There is a command variant, :VtrSendLinesToRunner! (note the ! at the end of the command) that is intended to provide a smoother workflow in that it will automatically open a runner if you have not yet done so.

That said, it currently hits the same error case if you've closed the pane and run it again. I think it would make sense for it to open a new runner instead of erroring.

I'm not sure when I'll get around to this as I have some more detailed refactoring I'd like to do to the pane attaching functionality (loosely captured in https://github.com/christoomey/vim-tmux-runner/issues/66), but I'll plan to incorporate this when I get around to those changes.

Is there any news on this topic. I really like vim-tmux-runner, but whenever I open up an additional pane manually, or close the runner pane, the system basically dies and I have to restart vim to get back the functionality.

@jerri here's a workaround that I use:

function! SendTmuxCommand(text)
  let panes = split(system("tmux list-panes"), '\n')
  let active = filter(copy(panes), 'v:val =~ "\\(active\\)"')
  let vimPane = str2nr(active[0])
  let cmdPane = vimPane + 1
  let panes = filter(panes, 'v:val =~ "^'.cmdPane.':.*"')
  if len(panes) == 0
    call system('tmux split-window -v -l 10')
    call system('tmux select-pane -t '.vimPane)
  endif
  let cmd = "tmux send-keys -t ".cmdPane." ".shellescape(a:text)
  call system(cmd)
endfunction

It always sends the command to the pane below the active one or creates a new one.

@Iaktak Thanks for the function! Just a couple of things:

On the third line from the bottom, shouldn't it be let cmd = "tmux send-keys -t ".cmdPane." ".shellescape(a:text) . " C-m"? Otherwise, it just sends the keys to the new pane instead of running the command.

Also, how might I have it automatically focus on the new pane? Would call system("tmux select-pane -t " . cmdPane) at the end of the function work?

Here's what I have after changing the above things:

function! SendTmuxCommand(text)
  let panes = split(system("tmux list-panes"), '\n')
  let active = filter(copy(panes), 'v:val =~ "\\(active\\)"')
  let vimPane = str2nr(active[0])
  let cmdPane = vimPane + 1
  let panes = filter(panes, 'v:val =~ "^'.cmdPane.':.*"')
  if len(panes) == 0
    call system('tmux split-window -v -l 10')
    call system('tmux select-pane -t '.vimPane)
  endif

  let cmd = "tmux send-keys -t ".cmdPane." ".shellescape(a:text . " && read -s -n 1 -p 'Press any key to continue . . .' && echo && exit") . " C-m"
  call system(cmd)
  call system("tmux select-pane -t " . cmdPane)
endfunction

Here's what it does:

• Opens a new pane
• Runs the supplied command in the new pane
• Selects the new pane
• Opens a prompt ("Press any key to continue . . ." just like the DOS pause command)
• After a key is pressed, closes the new pane

Thanks again @laktak!

Just ran into the same issue.

Does anyone know if this has been address in the plug-in or are above workarounds still the best way to go?
