search - Show Count of Matches in Vim

问题描述:

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?

网友答案:

Plugin index search.

Newest version here.

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'

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>

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.

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.

网友答案:
: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.

网友答案:

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.
