如何使用 peg.js 为更改行创建反斜杠？

Question

目前，我使用'\n'来分割每一行（段落），但现在，我想为换行做一个像python这样的反斜杠。

这是我当前的规则：

Start
    = _ head:Line tail:('\n'+ l:Line { return l })* _ {
        return [head].concat(tail)
    }

Line = (!'\n' .)+ { return { lines: [ text() ] } }

_ = [ \n\r\t]*

输入：

This is Line 1

This is \ Line
\ 2

当前输出：

[
   {
      "lines": [
         "This is Line 1"
      ]
   },
   {
      "lines": [
         "This is \ Line"
      ]
   },
   {
      "lines": [
         "\ 2"
      ]
   }
]

预期输出：

[
   {
      "lines": [
         "This is Line 1"
      ]
   },
   {
      "lines": [
         "This is",
         "Line",
         "2"
      ]
   },
]

Answer 1

哦，我自己实现了，这是我的代码：

{
  var lines = [];
  var lineText = "";
  function resetLines() {
    lines = [];
    lineText = "";
  }
}

Start
  = _ head:Line tail:("\n"+ l:Line { return l; })* _ {
      return [head].concat(tail);
    }

Line
  = ResetLines
    chars:(
      "\n"? "\" "\n"? {
          lines.push(lineText);
          lineText = "";
        }
      / !"\n" . { lineText += text(); }
    )+ {
      lines.push(lineText);
      return lines;
    }

ResetLines = &" "* { (lines = []), (lineText = ""); }

_ = [ \n\r\t]*

输入：

This is Line 1

This is\Line


This is Line 3

输出：

[
   [
      "This is Line 1"
   ],
   [
      "This is",
      "Line",
      "2"
   ],
   [
      "This is Line 3"
   ]
]
