Vim:如何索引纯文本文件? [英] Vim : how to index a plain text file?

问题描述

是否可以在vim中索引纯文本文件(一本书)，例如:

Is it possible to index a plain text file (a book) in vim such as :

1. This line contains the words : London, Berlin, Paris
2. In this line, I write about : New-York, London, Berlin
...
100. And, to conclude, my last comments about : New-York, Paris

并得到这个结果索引:

Berlin : 1
London : 1, 2
New-York : 2, ..., 100
Paris : 1, ..., 100

而且，如果可能的话，标记方法是什么?我读过关于 ctags 的文章，但它似乎专用于特定语言(说实话，对于我的需求来说有点矫枉过正)

and, if it is possible, what is the tagging method ? I have read about ctags, but it seems to be dedicated to specific languages (and to say the truth, a bit overkill for my needs)

推荐答案

这里是 Goulash 王子发布的函数的修订版.此版本将单词列表作为输入并返回结果的格式化和字母顺序字符串:

Here is a revised version of the function posted by Prince Goulash. This version takes a list of words as input and returns a formatted and alphabetized string of the result:

function! IndexByWord( wordlist )
    let temp_dict = {}
    for word in a:wordlist
        redir => result
        sil! exe ':g/' . word . '/#'
        redir END
        let tmp_list = split(strtrans(result),"\\^\@ *")
        let res_list = []
        call map(tmp_list, 'add(res_list,str2nr(matchstr(v:val,"^[0-9]*")))')
        let temp_dict[word]  = res_list
    endfor
    let result_list = []
    for key in sort(keys(temp_dict))
        call add(result_list, key . ' : ' . string(temp_dict[key])[1:-2])
    endfor
    return join(result_list, "\n")
endfunction

一种调用方式是:

echo IndexByWord(['word1', 'word2', 'word3', etc])

拥有一长串单词应该没有问题，尽管在这种情况下，您可能想要使用列表变量，而获得结果当然需要更多时间.例如:

There should be no problem with having a long list of words, although in that case you would probably want to use a list variable and getting the results would of course take more time. For example:

let my_word_list = ['word1', 'word2', . . . 'word1000']
echo IndexByWord(my_word_list)
