StdoutをCSVとJSONのブレンドに解析する方法は？

Question

JSONを残りの部分から分離するのは非常に簡単です。これはJSON以外のものを提供します。

python submit.py --provider gt --assignment error-check | sed '/{/,$d'

そしてこれはJSONだけです。

python submit.py --provider gt --assignment error-check | sed -n '/{/,$p'

これを説明するために、サンプル入力を次のように保存しましたfile。

$ sed '/{/,$d' file
Problem,Correct?,Correct Answer,Agent's Answer
"Challenge Problem B-04",0,4,-1
"Basic Problem B-12",0,1,-1
"Challenge Problem B-05",0,6,-1
"Challenge Problem B-07",0,6,-1
"Challenge Problem B-06",0,3,-1
"Basic Problem B-11",0,1,-1
"Basic Problem B-10",0,3,-1
"Challenge Problem B-03",0,3,-1
"Challenge Problem B-02",0,1,-1
"Challenge Problem B-01",0,6,-1
"Challenge Problem B-09",0,4,-1
"Challenge Problem B-08",0,4,-1
"Basic Problem B-08",0,6,-1
"Basic Problem B-09",0,5,-1
"Basic Problem B-04",0,3,-1
"Basic Problem B-05",0,4,-1
"Basic Problem B-06",0,5,-1
"Basic Problem B-07",0,6,-1
"Basic Problem B-01",0,2,-1
"Basic Problem B-02",0,5,-1
"Basic Problem B-03",0,1,-1
"Challenge Problem B-10",0,4,-1
"Challenge Problem B-11",0,5,-1
"Challenge Problem B-12",0,1,-1

そして

$ sed -n '/{/,$p' file
{
    "Basic Problems B": {
        "Incorrect": "0",
        "Skipped": "12",
        "Correct": "0",
        "Set": "Basic Problems B"
    },
    "Challenge Problems B": {
        "Incorrect": "0",
        "Skipped": "12",
        "Correct": "0",
        "Set": "Challenge Problems B"
    }
}

今、私は非JSONをすでにうまく処理しているので、変更しないでください。理想的には、JSONデータを解析するためにJSONパーサーを使用する必要があります（たとえば、少なくとも必要な操作を実行します（コマンドで置き換えます）jq。jqcat filepython submit.py --provider gt --assignment error-check

$ cat file | sed -n 's/[,"]//g; s/^ *//; /{/,$p'  | tac | awk -F': ' 'BEGIN{printf "%-30s%-10s%-10s%-10s\n", "Set", "Incorrect", "Skipped", "Correct"} NF==2 && !/\{/{if($1=="Set"){set=$2;data[set]["Incorrect"] = 0;data[set]["Skipped"] = 0;data[set]["Correct"] = 0;} data[set][$1]=$2}END{for(set in data){printf "%-30s%-10s%-10s%-10s\n", set,data[set]["Incorrect"],data[set]["Skipped"],data[set]["Correct"]}}' 
Set                           Incorrect Skipped   Correct   
Challenge Problems B          0         12        0         
Basic Problems B              0         12        0

これらすべてをシェルスクリプトに入れると、次のようになります。

#!/bin/bash

tmpFile=$(mktemp)
python submit.py --provider gt --assignment error-check > "$tmpFile";

sed '/{/,$d' "$tmpFile" | column -t -s, 
sed -n 's/[,"]//g; s/^ *//; /{/,$p' "$tmpFile" |
  tac |
  awk -F': ' '
    BEGIN{
      printf "%-30s%-10s%-10s%-10s\n", "Set", "Incorrect", "Skipped", "Correct"
    }
    NF==2 && !/\{/{
      if($1=="Set"){
         set=$2;
         data[set]["Incorrect"] = 0;
         data[set]["Skipped"] = 0;
         data[set]["Correct"] = 0;
      } 
      data[set][$1]=$2
    }
    END{
       for(set in data){
         printf "%-30s%-10s%-10s%-10s\n", set, 
                                     data[set]["Incorrect"], 
                                     data[set]["Skipped"], 
                                     data[set]["Correct"]}
    }' 
rm "$tmpFile"

ハッキングされているように感じても、誰かが専用のJSONパーサーを使用してよりきれいな解決策を思い付くことを願っています。

スチールドライバーjqコメントに正しい解決策が提供されてうれしいので、それを含めるとより簡単で安全な解決策が得られます。

#!/bin/bash

tmpFile=$(mktemp)
python submit.py --provider gt --assignment error-check > "$tmpFile";

sed '/{/,$d' "$tmpFile" | column -t -s, 
sed -n '/{/,$p' "$tmpFile" | 
  jq -r '["Set","Incorrect","Skipped","Correct"], (.[] | [.Set,.Incorrect,.Skipped,.Correct]) | @tsv'
 rm "$tmpFile"
