相当于 Python 文件的 % 移动 [英] Equivalent of % movement for Python files

问题描述

对于用 {} 表示块的语言，vim 有全能的 % 键.python代码的等效运动是什么?或者至少以相同的缩进移动到下一行/上一行.

For languages with {} to denote blocks, vim has the almighty % key. What is the equivalent movement thing for python code? Or at least to move to next / previous line with the same indent.

推荐答案

vim wiki 建议绑定，例如:

nnoremap <M-,> k:call search('^'. matchstr(getline(line('.')+1), '\(\s*\)') .'\S', 'b')<CR>^
nnoremap <M-.> :call search('^'. matchstr(getline(line('.')), '\(\s*\)') .'\S')<CR>^

以及提供更全面的解决方案:

As well as offering a more comprehensive solution:

" Jump to the next or previous line that has the same level or a lower
" level of indentation than the current line.
"
" exclusive (bool): true: Motion is exclusive
" false: Motion is inclusive
" fwd (bool): true: Go to next line
" false: Go to previous line
" lowerlevel (bool): true: Go to line with lower indentation level
" false: Go to line with the same indentation level
" skipblanks (bool): true: Skip blank lines
" false: Don't skip blank lines
function! NextIndent(exclusive, fwd, lowerlevel, skipblanks)
  let line = line('.')
  let column = col('.')
  let lastline = line('$')
  let indent = indent(line)
  let stepvalue = a:fwd ? 1 : -1
  while (line > 0 && line <= lastline)
    let line = line + stepvalue
    if ( ! a:lowerlevel && indent(line) == indent ||
          \ a:lowerlevel && indent(line) < indent)
      if (! a:skipblanks || strlen(getline(line)) > 0)
        if (a:exclusive)
          let line = line - stepvalue
        endif
        exe line
        exe "normal " column . "|"
        return
      endif
    endif
  endwhile
endfunction

" Moving back and forth between lines of same or lower indentation.
nnoremap <silent> [l :call NextIndent(0, 0, 0, 1)<CR>
nnoremap <silent> ]l :call NextIndent(0, 1, 0, 1)<CR>
nnoremap <silent> [L :call NextIndent(0, 0, 1, 1)<CR>
nnoremap <silent> ]L :call NextIndent(0, 1, 1, 1)<CR>
vnoremap <silent> [l <Esc>:call NextIndent(0, 0, 0, 1)<CR>m'gv''
vnoremap <silent> ]l <Esc>:call NextIndent(0, 1, 0, 1)<CR>m'gv''
vnoremap <silent> [L <Esc>:call NextIndent(0, 0, 1, 1)<CR>m'gv''
vnoremap <silent> ]L <Esc>:call NextIndent(0, 1, 1, 1)<CR>m'gv''
onoremap <silent> [l :call NextIndent(0, 0, 0, 1)<CR>
onoremap <silent> ]l :call NextIndent(0, 1, 0, 1)<CR>
onoremap <silent> [L :call NextIndent(1, 0, 1, 1)<CR>
onoremap <silent> ]L :call NextIndent(1, 1, 1, 1)<CR>

用途:

• [l 和 ]l 跳转到与当前行具有相同缩进级别的上一行或下一行.
• [L 和 ]L 跳转到上一行或下一行，缩进级别低于当前行.

• [l and ]l jump to the previous or the next line with the same indentation level as the current line.
• [L and ]L jump to the previous or the next line with an indentation level lower than the current line.
