Indenting fold text

Question

When you unfold nested levels of your code the folded text in nested code is not indented. It begins on the beginning of the line with + instead of starting indented.

Do you know how to change it?

Answer 1

If you want the fold text to be indented at the same level as the first line of the fold, you need to prepend the indent level to the foldtext:

function! MyFoldText()
    let indent_level = indent(v:foldstart)
    let indent = repeat(' ',indent_level)
    ...
    ...   
    return indent . txt
endfunction

Here I am assuming that the string txt is your existing foldtext, so all you need to do is add it to the end of indent.

But I am not sure if that is what you want to achieve.

EDIT:

Now I have seen your picture, I'm not sure if this is what you want. You could try stripping the leading whitespace before appending to the +. So the foldtext you want will be something like indent . '+' . txt.

Maybe.

Answer 2

Aha

You might want to comment out this function in your .vimrc:

set foldtext=MyFoldText()
set fillchars=fold:_

This is what makes your fold text appearing non default, by using the function:

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

As it happens, I quite like that function, but of course, de gustibus...
