jq select object whose key value in the list-CodePudding

I have one script ./getClasses.sh which returns comma separated list like ApexClass1,ApexClass2. There are more than two items in this list.

I want to use that list in jq to filter out JSON values by a certain key value, which coincides with one value from the list

I tried in operator

echo $(cat tests.json) | jq '.result.coverage.coverage[] | select(.name included($(./getClasses.sh)))'

and includes operator

echo $(cat tests.json) | jq '.result.coverage.coverage[] | select(.name in($(./getClasses.sh)))'

but both of them are failing with en error

jq: error: syntax error, unexpected IDENT, expecting ';' or ')' (Unix shell quoting issues?) at <top-level>, line 1:

File tests.json contains a following JSON

{"status": 0,
  "result": {
    "summary": {
      "outcome": "Passed",
      "testsRan": 13,
      "passing": 13,
      "failing": 0,
      "skipped": 0,
      "passRate": "100%",
      "failRate": "0%"}, "tests": [], "coverage": {
      "coverage": [
        {
          "name": "ApexClass1",
          "totalLines": 25,
          "lines": {},
          "totalCovered": 23,
          "coveredPercent": 92}, {
          "name": "ApexClass2",
          "totalLines": 25,
          "lines": {},
          "totalCovered": 23,
          "coveredPercent": 92}, {
          "name": "ApexClass3",
          "totalLines": 25,
          "lines": {},
          "totalCovered": 23,
          "coveredPercent": 92}
      ],
      "records": []
    } } }

How can I achieve the desired output?

I think I got it.

I need to pass the strings as argument and then split it by comma and unbracket them like this:

classes=$(./getClasses.sh)
echo $(cat tests.json) | jq --arg classes $classes '.result.coverage.coverage[] | select(.name == ($classes | split(",")[])) | .totalLines' | awk '{s =$1} END {print s}'

CodePudding user response：

Another option using inside() ^[docs] to check if .name exist in an array.

The array is build using: "ApexClass1,AapexClass2" | split(",") ^[docs]

jq '[ .result.coverage.coverage[] | select([ .name ] | inside("ApexClass1,AapexClass2" | split(",") ) ) | . ]' tests.json

[
  {
    "name": "ApexClass1",
    "totalLines": 25,
    "lines": {},
    "totalCovered": 23,
    "coveredPercent": 92
  },
  {
    "name": "ApexClass2",
    "totalLines": 25,
    "lines": {},
    "totalCovered": 23,
    "coveredPercent": 92
  }
]
