我正在使用已发布的here和here的VIM折叠设置。现在,请注意以下程序:
折叠在我的VIM上时会产生以下结果:
我不喜欢那种表情,我更喜欢以下内容:
我通过重写代码得到了:
但是留下这样的代码是可怕的。是否有可能更新VimScript以便我得到我想要的折叠,而不必像这样留下JavaScript代码?
这是我的确切设置:
setlocal foldmethod=expr
setlocal foldexpr=GetPotionFold(v:lnum)
setlocal foldminlines=0
function! s:NextNonBlankLine(lnum)
let numlines = line('$')
let current = a:lnum + 1
while current <= numlines
if getline(current) =~? '\v\S'
return current
endif
let current += 1
endwhile
return -2
endfunction
function! s:IndentLevel(lnum)
return indent(a:lnum) / &shiftwidth
endfunction
function! GetPotionFold(lnum)
if getline(a:lnum) =~? '\v^\s*$'
return '-1'
endif
let this_indent = <SID>IndentLevel(a:lnum)
let next_indent = <SID>IndentLevel(<SID>NextNonBlankLine(a:lnum))
if next_indent == this_indent
return this_indent
elseif next_indent < this_indent
return this_indent
elseif next_indent > this_indent
return '>' . next_indent
endif
endfunction
function! NeatFoldText()
let line = getline(v:foldstart)
let lines_count = v:foldend - v:foldstart + 1
let lines_count_text = '| ' . printf("%10s", lines_count . ' lines') . ' |'
let foldchar = ' '
let foldtextstart = strpart(line, 0, (winwidth(0)*2)/3)
let foldtextend = lines_count_text . repeat(foldchar, 6)
let foldtextlength = strlen(substitute(foldtextstart . foldtextend, '.', 'x', 'g')) + &foldcolumn
return foldtextstart . repeat(foldchar, winwidth(0)-foldtextlength) . foldtextend
endfunction
set foldtext=NeatFoldText()
hi Folded ctermbg=255 ctermfg=21
hi FoldColumn ctermbg=white ctermfg=darkred
以下是示例代码:
function foo(x){
var y = x*x;
var z = y+y;
return z;
};
function bar(x){
var y = x*x;
var z = y+y;
return z;
};
function foobar(x){
var y = x*x;
var z = y+y;
return z;
};
function barfoo(x){
var y = x*x;
var z = y+y;
return z;
};

set foldmethod=marker
set foldmarker={,}
应该给你你想要的东西。

你正在使用折叠表达式(据我所知,一目了然)设计用于缩进折叠(用于HAML,Python,Haskell和其他缩进语法语言)。
对于C,您应该使用:set foldmethod=syntax
。
