Vim:获取光标下语法元素的内容 [英] Vim: Get content of syntax element under cursor

问题描述

我在一个突出显示的复杂语法元素上，想获取它的内容.你能想到什么方法来做到这一点吗?

I'm on a highlighted complex syntax element and would like to get it's content. Can you think of any way to do this?

也许有某种方法可以搜索正则表达式以使其包含光标?

编辑

好的，举个例子.光标在一个字符串内，我想获取文本，即该句法元素的内容.考虑以下行:

Okay, example. The cursor is inside a string, and I want to get the text, the content of this syntactic element. Consider the following line:

String myString = "Foobar, [CURSOR]cool \"string\""; // And some other "rubbish"

我想写一个返回的函数

"Foobar, cool \"string\""

推荐答案

看到 nelstrom 提到的插件的工作方式与我原来的方法相似，我决定采用这个稍微优雅的解决方案:

Seeing that the plugin mentioned by nelstrom works similar to my original approach, I settled on this slightly more elegant solution:

fu s:OnLink()
    let stack = synstack(line("."), col("."))
    return !empty(stack)
endf

normal mc 

normal $
let lineLength = col(".")
normal `c

while col(".") > 1
    normal h
    if !s:OnLink()
        normal l
        break
    endif
endwhile
normal ma`c

while col(".") < lineLength
    normal l
    if !s:OnLink()
        normal h
        break
    endif
endwhile
normal mb`av`by
