# Output the compiled JSON file / you can display it using jq for clean display or  you could keep the output be sJSON variable if you really wanted to not have to use jq

# OR YOU CAN USE jq to return a pretty version of this / Just comment the above line and uncomment the below line, this would require you to have jq installed
#echo "${sJSON}" | jq ".";

# Example Usage: ( All these Examples do require you to have jq install Ubuntu/Debian: sudo apt-get install jq )
# getBranches.sh is the name of the script file I have set, just change this to what you name the script file as.

# 1. This will build a JSON that will seperate each version with build id, time updated, and description
#sudo ./getBranches.sh | jq ".[].depots.branches | to_entries[] | {"version": .key, "id": .value.buildid, "updated": .value.timeupdated, "desc": .value.description}";

# 2. This Example shows how you can iterate over all the branches and display the info for them.
#vout=$(sudo ./getBranches.sh); V=$(echo "${vout}" | jq -r ".[].depots.branches | to_entries[].key"); for a in $V; do echo "Key: $a"; echo "${vout}" | jq -r ".[].depots.branches.\"$a\""; done

# 3. Get a specific branch you know the name of and return the buildid
#sudo ./getBranches.sh | jq ".[].depots.branches.\"alpha18.0\".buildid";
