Show Count of Matches in Vim

问题

There is a nice feature in Google Chrome when you do a search. It tells you the number of matches there is for the keyword you are searching for. However, in Vim I don't see such a feature. Some people suggested using %s/pattern//gn or similar:

http://vim.wikia.com/wiki/Count_number_of_matches_of_a_pattern
Unable to count the number of matches in Vim

But that is quite long really!! I am looking for the count when a press the '*', '%', or do any search using '/' and '?'.

Any idea?

回答1:

Plugin index search.

Newest version here.

回答2:

I don't know of a direct way of doing it, but you could make use of the way :%s/// uses the last search as the default pattern:

:nmap ,c :%s///gn

You should then be able to do a search and then hit ,c to report the number of matches.

The only issue will be that * and # ignore 'smartcase', so the results might be off by a few after using *. You can get round this by doing * followed by /UpENTER and then ,c.

One addition to @Al's answer: if you want to make vim show it automatically in the statusline, try adding the following to the vimrc:

let s:prevcountcache=[[], 0]
function! ShowCount()
    let key=[@/, b:changedtick]
    if s:prevcountcache[0]==#key
        return s:prevcountcache[1]
    endif
    let s:prevcountcache[0]=key
    let s:prevcountcache[1]=0
    let pos=getpos('.')
    try
        redir => subscount
        silent %s///gne
        redir END
        let result=matchstr(subscount, '\d\+')
        let s:prevcountcache[1]=result
        return result
    finally
        call setpos('.', pos)
    endtry
endfunction
set ruler
let &statusline='%{ShowCount()} %<%f %h%m%r%=%-14.(%l,%c%V%) %P'

Here's a cheap solution ... I used Find and Replace All in Vim. No fancy scripting. I did a Find X and Replace All with X. At the end, Vim reports "2134 substitutions on 9892 lines". X appeared 2134 times. Use :q! to quit the file without saving it. No harm done.

You already have a good wealth of answers, but it seems to me that there is still one more approach to this problem.

This is actually something I had to deal with a few days ago. I added a function and a mapping in such a way that you hit the mapping when the cursor is under the word you want to count and it returns the number of matches.

The Function:

" Count number of occurances of a word
function Count(word)
    let count_word = "%s/" . a:word . "//gn"
    execute count_word
endfunction

And the mapping:

" Count current word 
nmap <Leader>w <Esc>:call Count(expand("<cword>"))<CR>

回答6:

Alternatively from what @Al suggests you can map the key combination to write most of the line and then move the cursor to the position where the actual pattern is inserted:

:nmap ,c ^[:%s///gn^[OD^[OD^[OD^[OD

Where '^[' is Ctrl+V,Esc and '^[OD' is Ctrl+V,Left

Then pressing ',c' will go into command mode, enter the pattern and leave the cursor over the second '/', ready to insert the pattern.

This plugin does just that. https://github.com/osyo-manga/vim-anzu

When searching for a word in vim, it will display word count on the statusline. It also has the option to display next to the searched word ie. this_is_my_sample_word (3/12), or this_is_my_sample_word(7/12). This basically says: this is the 3rd or 7th occurrence out of 12 total occurrences.

I'm not sure exactly what version added it, but this is built into Vim now, you just need to:

:set shortmess-=S

Added sometime in the 8.1.x patches (as of this writing we're at 8.1.2300).

:vim[grep][!] /{pattern}/[g][j] {file} ...

Vimgrep uses Vim's built-in regex search engine, so you can reuse the patterns from Vim's standard search command. So, I first test the search pattern the normal way using: /{pattern}/

Then enter the following:

:vim /CTRL+r//g %

where CTRL+r/ will insert the last search pattern after the first slash. The status line will display (1 of max), where max is the maximum number of matches for the {pattern}. Then use the :cnext and :cprev to search for the next & previous matches and :cfirst and :clast for the first and last matches. These 4 commands can be remapped to make them faster to execute.
