根据多个匹配条件连接来自非相邻对象的值

Question

我以前在这个论坛上，想知道是否有类似的直接方法来解决更复杂的问题。

给定以下代码片段，是否有一种方法可以根据匹配文本大小？当我尝试调整相关问题的答案时，我很快运行进入问题，但我基本上是在寻找 t运行制定规则，例如 if .Text !endswith("[punctuation mark][white space]") then .Text + next .Text where .TextSize matches

  {
    "Text": "Was it political will that established social democratic policies in the 1930s and ",
    "Path": "P",
    "TextSize": 9
  },
  {
    "Text": "31 Lawrence Mishel and Jessica Schieder, Economic Policy Institute website, May 24, 2016 at (https://www.epi.org/publication/as-union-membership-has-fallen-the-top-10-percent-have-been-getting-a-larger-share-of-income/). ",
    "Path": "Footnote",
    "TextSize": 8
  },
  {
    "Text": "Fig. 9.2 Higher union membership has been associated with a higher share of income to lower income brackets (the lower 90%) and a lower share of income to the top 10% of earners. ",
    "Path": "P",
    "TextSize": 8
  },
  {
    "Text": "1940s, or that undermined them after the 1970s? Or was it abundant and cheap energy resources that enabled social democratic policies to work until the 1970s, and energy constraints that forced a restructuring of policy after the 1970s? ",
    "Path": "P",
    "TextSize": 9
  },
  {
    "Text": "Recall that my economic modeling discussed in Chap. 6 shows that, even with no change in the assumption related to labor \u201cbargaining power,\u201d you can explain a shift from increasing to declining income equality (higher equality expressed as a higher wage share) by a corresponding shift from a period of rapidly increasing per capita resource consumption to one of constant per capita resource consumption. ",
    "Path": "P",
    "TextSize": 9
  }

我要查找的结果如下：

  {
    "Text": "Was it political will that established social democratic policies in the 1930s and 1940s, or that undermined them after the 1970s? Or was it abundant and cheap energy resources that enabled social democratic policies to work until the 1970s, and energy constraints that forced a restructuring of policy after the 1970s? ",
    "Path": "P",
    "TextSize": 9
  },
  {

Answer 1

以下假定输入是一个有效的 JSON 数组，将每个 .Text 与最多一个后继者合并，但可以轻松修改以将多个 .Text 值合并在一起，如第 2 部分所示下面。

第 1 部分

# input and output: an array of {Text, Path, TextSize} objects.
# Attempt to merge the .Text of the $i-th object with the .Text of a subsequent compatible object.
# If a merge is successful, the subsequent object is removed.
def attempt_to_merge_next($i):
  .[$i].TextSize as $class
  | first( (range($i+1; length) as $j | select(.[$j].TextSize == $class) | $j) // null) as $j
  | if $j then .[$i].Text += .[$j].Text | del(.[$j])
    else .
    end;

reduce range(0; length) as $i (.;
  if .[$i] == null then .
  elif .[$i].Text|test("[,.?:;]\s*$")|not
  then attempt_to_merge_next($i)
  else .
  end)

第 2 部分

使用上面的def:

def merge:
  def m($i):
    if $i >= length then .
      elif .[$i].Text|test("[,.?:;]\s*$")|not
      then attempt_to_merge_next($i) as $x
      | if ($x|length) == length then m($i+1)
        else $x|m($i)
        end
      else m($i+1)
      end ;
  m(0);

merge
