Mappings with counts at the end without using loops?

Question

Suppose you are trying to create a set of mappings such that pressing <C-t> followed by a number # would alternate to the respective tab at index #. I know that using a loop, I can do:

" Map alt-x keys to jump to a tab
for i in range(1, 9)
  execute "nmap \<C-t>" . i . "> " . i . "gt"
endfor

Such a solution, however, hast the disadvantage of allowing only a mapping that recognizes up to 9. Is there a more general way to have a mapping depend on a count pressed at the end of the mapping, for instance such that hitting <C-t>14 would focus tab number 14?

Note: the above is just an example, I am interested in this regardless of tabs per se.

Answer 1

The problem with having a count at the end is Vim will have to wait to see if more keys are going to be pressed. E.g. <c-t>1 might mean you are supplying a count of 1 or maybe it will end up being 14.

The other problem is you have to make all these mappings. So if you want to support a count up to 15, then you need 15 mappings.

Options:

• Provide a terminating sequence. e.g. <c-t>{count}<c-t>. Still have to create lot of mappings, but it will allow for a "count"
• Simply use Vim's native <count> which is a proceeds the map sequence. e.g. 4gt. This means one mapping and the count will work correctly.

Aside about tabs and buffers

Your mappings suggest a heavy tab centric workflow. I know it might sound weird but maybe try and use less tab panes together with a more buffers centric workflow. Here are some nice posts about it:
