Answer 1

• Ctrl+H
• 找什么：\h+(\w+)(\R?)(\w)?
• 用。。。来代替：'$1'(?3$2:,)$3
• 查看 环绕
• 查看 正则表达式
• Replace all

解释：

\h+         # 1 or more horizontal spaces
(\w+)       # group 1, 1 or more word characters
(\R?)       # group 2, any kind of linebreak, optionnal
(\w)?       # group 3, optionnal, a word character

替代品：

'               # single quote
$1              # content of group 1
'               # single quote
(?3             # if group 3 exists (i.e. there is a word chracter at the beginning of next line)
    $2              # add content of group 2, the linebreak
  :               # else
    ,               # add a comma
)               # endif
$3              # content of group 3
