更改折叠中的文本 [英] Change the text in folds

问题描述

我注意到折叠文本可以显示有用的信息.他们通常会显示类似

+-- 5 行:<div id="header-inner">-------------------------------------------

是否可以更改这些行中的文本?我注意到在 foldexpr 中有些东西是可能的，但是否有可能完全重新设计折叠?
例如
+

:上面一行的可能评论":第 27 行:长度 5

谢谢

解决方案

从你的问题中我有一些不明白的地方，比如你使用的是哪种折叠方法，或者行"的数量是指什么，但这里有一个自定义的 foldtext 函数，它应该可以大致满足您的要求:

函数！我的折叠文本()让 nl = v:foldend - v:foldstart + 1让评论 = 替代(getline(v:foldstart)，^ *"，"，1)让 linetext = 替代(getline(v:foldstart+1),"^ *","",1)让 txt = '+ ' .行文本.':'.评论.'":长度'.nl返回txt端功能设置 foldtext=MyFoldText()

说明:

1. 找出折叠包含的行数.
2. 从第一条折叠线之前的行中获取注释"(并删除前导空格).
3. 从折叠的第一行获取文本(并删除前导空格).
4. 使用适当的格式将上述信息组合到返回的折叠文本中.

希望这会有所帮助.它应该可以轻松满足您的需求.

I noticed that fold texts can show useful information. They usually show something like

+-- 5 lines: <div id="header-inner">--------------------------------------------

Is it possible to change the text in those lines? I noticed that something is possible in foldexpr but would it be possible to completely redesign folds?
e.g.
+ <div id="header-inner"> : "possible comment from line above" : row 27 : length 5

thank you

解决方案

There are a few things I don't understand from your question, such as which foldmethod you are using, or what the number of "rows" refers to, but here's a custom foldtext function that should do roughly what you want:

function! MyFoldText()
    let nl = v:foldend - v:foldstart + 1
    let comment = substitute(getline(v:foldstart),"^ *","",1)
    let linetext = substitute(getline(v:foldstart+1),"^ *","",1)
    let txt = '+ ' . linetext . ' : "' . comment . '" : length ' . nl
    return txt
endfunction
set foldtext=MyFoldText()

Explanation:

1. Find the number of lines contained by the fold.
2. Get the "comment" from the line before the first folded line (and remove leading spaces).
3. Get the text from the first line of the fold (and remove leading spaces).
4. Assemble the above information into the returned foldtext, with appropriate formatting.

Hope this helps. It should be easily tailored to your needs.
