如何在Vim中指定光标下的行？

Question

I want to count number of occurrences of the line under the cursor. I intend to do it with the

:%s/pattern/&/gn

command. So how do I specify the line under cursor in place of pattern ?

Answer 1

You can insert the current line via the expression register . For a literal match, switch the regular expression to very nomagic mode ( \\V ), and escape any backslashes and the separator in the line:

:%s/\V<C-r>=escape(getline('.'), '/\')<CR>/&/gn

Depending on what you want to count exactly, you may also need to anchor ( \\^...\\$ in very nomagic mode) the pattern.

Instead of direct insertion via <Cr> , you can also build the command via :execute . This is more suitable in a function.

:execute '%s/\V' . escape(getline('.'), '/\') . '/&/gn'

Answer 2

If you're looking for a canned plugin solution, my SearchPosition plugin can count occurrences. With it, V<Am> will show a summary like this:

On sole match in this line, 8 following, 2 in previous lines; total 10 for /this line\n/
