Adding numbers that are not in array format? Or how to filter to array so I can sum up





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

In previous versions of jq I was able to run the following:



cat pull_requests.json | jq '.data.organization.repositories.nodes | .pullRequests.totalCount | add'


On this sample data:



{
"data": {
"organization": {
"repositories": {
"nodes": [{
"pullRequests": {
"totalCount": 2
}
},
{
"pullRequests": {
"totalCount": 8
}
},
{
"pullRequests": {
"totalCount": 23
}
}
]
}
}
}
}


And I would get the correct result.



But currently on jq-1.6 I am getting the following error:



jq: error (at <stdin>:24): Cannot iterate over number (2)


What I noticed from the output without the add filter is that is not an array:



➤ cat pull_requests.json | jq '.data.organization.repositories.nodes | .pullRequests.totalCount'
2
8
23


So my question is how to add these numbers up?



I also tried casting it to array by using [.pullRequests.totalCount] but I was unable to merge, meld, join the arrays to get the final count.

  • For now I am doing cat pull_requests.json | jq '.data.organization.repositories.nodes | .pullRequests.totalCount' | awk '{s+=$1}END{print s}' but I would like to use only jq in this case because it used to work.

You are mistaken in thinking that the jq filter as shown used to work on the JSON as shown.



There are fortunately two simple fixes:



[ .data.organization.repositories.nodes
| .pullRequests.totalCount ]
| add


or:



.data.organization.repositories.nodes
| map(.pullRequests.totalCount)
| add


Using sigma/1



Another option is to use a stream-oriented summation function:



def sigma(s): reduce s as $s (null; .+$s);

.data.organization.repositories.nodes
| sigma(..pullRequests.totalCount)
