使 { 和 } 忽略仅包含空格的行 [英] Make { and } ignore lines containing only whitespace

问题描述

当您在 vim 中使用 { 和 } 按段落导航时，它会跳过除空白之外什么都不包含的行，尽管它们是空白".

When you navigate by paragraph in vim using { and } it skips lines that contain nothing but whitespace though they are otherwise 'blank'.

如何说服 vim 将仅空白"行视为分段符，以便 { 和 } 跳转到它们?

How can I convince vim to treat "whitespace only" lines as paragraph breaks so { and } will jump to them?

推荐答案

这是一个正确处理计数的修改版本:

Here's a modified version that handles counts correctly:

function! ParagraphMove(delta, visual, count)
    normal m'
    normal |
    if a:visual
        normal gv
    endif

    if a:count == 0
        let limit = 1
    else
        let limit = a:count
    endif

    let i = 0
    while i < limit
        if a:delta > 0
            " first whitespace-only line following a non-whitespace character           
            let pos1 = search("\\S", "W")
            let pos2 = search("^\\s*$", "W")
            if pos1 == 0 || pos2 == 0
                let pos = search("\\%$", "W")
            endif
        elseif a:delta < 0
            " first whitespace-only line preceding a non-whitespace character           
            let pos1 = search("\\S", "bW")
            let pos2 = search("^\\s*$", "bW")
            if pos1 == 0 || pos2 == 0
                let pos = search("\\%^", "bW")
            endif
        endif
        let i += 1
    endwhile
    normal |
endfunction

nnoremap <silent> } :<C-U>call ParagraphMove( 1, 0, v:count)<CR>
onoremap <silent> } :<C-U>call ParagraphMove( 1, 0, v:count)<CR>
" vnoremap <silent> } :<C-U>call ParagraphMove( 1, 1)<CR>
nnoremap <silent> { :<C-U>call ParagraphMove(-1, 0, v:count)<CR>
onoremap <silent> { :<C-U>call ParagraphMove(-1, 0, v:count)<CR>
