VIM 突出显示缓冲区中的唯一单词

Question

当使用vim进行编程时，文件/缓冲区中的任何唯一单词很可能是拼写错误（以太变量名称，方法名称或语言结构）。因此，捕获此类拼写错误并能够突出显示文件中任何唯一单词的好方法，而无需任何花哨的语言分析或解析，甚至不需要知道正在使用哪种编程语言。当然，最好在键入时发生这种情况，以便您可以立即看到拼写错误。不知何故，我不认为我是第一个提出这样想法的人，所以也许有人有这样的设置或有任何建议？

Answer 1

创意。

我用这个 Vimscript 片段做了一些快速的原型设计：

let stat = {}
for ii in range(1, line('$'))
    for word in split(getline(ii), '(k@!.)+')
        let stat[word] = get(stat, word, 0) + 1
    endfor
endfor
echo sort(keys(filter(copy(stat), 'v:val == 1')))

在 $VIM/vim73/autoload/vimball.vim（一个包含 737 行的 23.2 k 文件）上运行它，我得到以下单个关键字出现：

嗯，对我来说看起来不是很有用（当排除评论时也不会变得更好），但也许你可以接受它并改进它。
