As title. I want to detect the case when there is only one split in the current tab.

Start with:

echo tabpagewinnr(tabpagenr(), '$')

tabpagenr() gives you the number of the current tab page.

Use '$' as the second param to tabpagewinnr() and that function will return the number of windows contained in the specified tab page.

So you can test for single window (no splits) with something like:

if tabpagewinnr(tabpagenr(), '$') == 1
    " do something
endif

  • I answered with the first thing that occurred to me. If I had more time I might find something that just uses function calls but I'm a little short on time right now.
