Functions ​

When dealing with tabs, windows and buffers, there are a few useful functions:

FunctionDescription
bufexists()Returns true if the buffer exists.
bufnr()Number of a buffer.
tabpagenr()Number of the current tab page.
tabpagewinnr()Number of the window in the context of tab pages.

When getting the number of a buffer/window etc, one can use:

  • $ to get the number of entries (higher buffer number, number of windows)
  • # to get the last accessed entry number (last buffer or window)

Examples ​

To get the number of windows in the current tab:

vim
tabpagewinnr(tabpagenr(), '$')
