Add this line to your vimrc to have Vim show how many lines you moved between when you hit the % key (which moves between matching pairs of characters, such as parenthesises and braces). The number of lines will be displayed at the bottom of the screen, positive for down, negative for up.

Especially useful when programming Java, C++, Perl, as % easily lets you count how many lines are in a method, class, or clause. Note that ^M needs to be typed as Ctrl+V, Ctrl+M.

" Count number of lines within this matching pair, print them
" when jumping between braces with %. Very useful. By shellreef.
nnoremap % :let line=line(".")^M%:echo line(".") - line^M

Comments

Good tip but the mapping woun't work. The problem is you are setting line and retrieving the actual line without moving the cursor. This would work better:

let showline=0
nnoremap ! :let newline=line(".")<enter>:let numlines=newline-showline<enter>:let showline=newline<enter>:echo numlines<enter>

The % moves the cursor; the mapping works for me. I could see how your mapping would be useful to mark a line, move to another line, and find out how many lines you moved--a more general case than mine.

Another way to do the same is folowing:

:set showcmd

After this, in bottomright corner of vim window you will see count of lines currently selected (if there are any). And many other useful things too. :)

Now, to see how many lines is between pairs, you set cursor on first pair, enter visual mode and press %. Now in bottomright corner you see desired number.

-t7ko--cool, never knew how useful visual mode could be. Thanks.
