python - 使用 vim 自动缩进 python else 语句

Question

在 vim 中，我想编写如下代码:

def a():
    if a: pass
    elif b: pass
    else: pass

我使用自动缩进，但代码将缩进为:

def a():
    if a: pass
    elif b: pass
else: pass

else 语句的自动缩进是错误的。我该如何解决这个问题？

请注意，以下代码片段已正确缩进:

def a():
    if a: pass
    else: pass

这是我完整的 .vimrc:

我认为这是 Vim 发行版中包含的 indent/python.vim 文件中的错误。

要检查它，将文件从 $VIMRUNTIME/indent/python.py 复制到您的 vim 主目录(例如 $HOME/.vim/indent/python.py) 并查找以下段落(接近文件末尾):

    " Unless the previous line was a one-liner
    if getline(plnumstart) =~ '^\s*\(for\|if\|try\)\>'
      return plindent
    endif

更改条件以检查关键字 elif 也:

    " Unless the previous line was a one-liner
    if getline(plnumstart) =~ '^\s*\(for\|if\|elif\|try\)\>'
      return plindent
    endif

重新启动 Vim 并完成!
