Add to existing json file using jq - json

Question

I have an Artifactory AQL Spec file in JSON format. The spec file is as follows:
{
"files": [
{
"aql": {
"items.find": {
"repo": "release-repo",
"modified": { "$before": "30d" },
"type": { "$eq": "folder" },
"depth": "2"
}
}
}
]
}
let's say I run a gitlab api query to acquire a list of SHAs that I want to iterate through and add to this json spec file.. The list of SHAs are assigned to a variable..
"a991fef6bb9e9759d513fd4b277fe3674b44e4f4"
"5a562d34bb1d4ab4264acc2c61327651218524ad"
"d4e296c35644743e58aed35d1afb87e34d6c8823"
I would like to iterate through all these commit IDs in and add them one by one to the json so that they are in this format:
{
"files": [
{
"aql": {
"items.find": {
"repo": "release-repo",
"modified": { "$before": "30d" },
"type": { "$eq": "folder" },
"$or": [
{
"$and": [
{
"name": {
"$nmatch": "*a991fef6bb9e9759d513fd4b277fe3674b44e4f4*"
}
}
]
},
{
"$and": [
{
"name": {
"$nmatch": "*5a562d34bb1d4ab4264acc2c61327651218524ad*"
}
}
]
},
{
"$and": [
{
"name": {
"$nmatch": "*d4e296c35644743e58aed35d1afb87e34d6c8823*"
}
}
]
}
],
"depth": "2"
}
}
}
]
}
The list of SHAs returned from the gitlab api query will be different everything and that's why I'd like this to be a dynamic entry or update every time. The number of returned SHAs will also be different... Could return 10 one day or it could return 50 on another day.

#!/usr/bin/env bash
template='{
"files": [
{
"aql": {
"items.find": {
"repo": "release-repo",
"modified": { "$before": "30d" },
"type": { "$eq": "folder" },
"$or": [],
"depth": "2"
}
}
}
]
}'
shas=(
"a991fef6bb9e9759d513fd4b277fe3674b44e4f4"
"5a562d34bb1d4ab4264acc2c61327651218524ad"
"d4e296c35644743e58aed35d1afb87e34d6c8823"
)
jq -n \
--argjson template "$template" \
--arg shas_str "${shas[*]}" \
'
reduce ($shas_str | split(" ") | .[]) as $sha ($template;
.files[0].aql["items.find"]["$or"] += [{
"$and": [{"name": {"$nmatch": ("*" + $sha + "*")}}]
}]
)
'
...emits as output:
{
"files": [
{
"aql": {
"items.find": {
"repo": "release-repo",
"modified": {
"$before": "30d"
},
"type": {
"$eq": "folder"
},
"$or": [
{
"$and": [
{
"name": {
"$nmatch": "*a991fef6bb9e9759d513fd4b277fe3674b44e4f4*"
}
}
]
},
{
"$and": [
{

},
{

"depth": "2"
}
}
}
]
}

Here is a reduce-free solution. It makes some inessential assumptions -
that the sha strings are presented as a stream of strings on STDIN, and that the Artifactory spec is in a file named spec.json. Here is the jq program:
map( {"$and": [ {name: { "$nmatch": "*\(.)*" }}]} ) as $x
| $spec[0] | (.files[0].aql."items.find"."$or" = $x)
The jq invocation might look like this:
jq -s --slurpfile spec spec.json -f program.jq <<< "${shas[*]}"
