Formats JSON log lines (naively assumed to start with "{") in console output while preserving the non-JSON lines

json-logs.sh

jlog() {
	local FORMAT=${FORMAT:-'"\(.timestamp) \(.level)\t - \(.name) - \(.message)\t\t\(del(.timestamp, .message, .level, .name, .traceback))\(if .traceback then "\r\n\(.traceback | gsub("\n"; "\r\n"))" else "" end)\r"'}
	tee >( grep --line-buffered -v "^{" > /dev/tty ) | grep --line-buffered "^{" | jq --raw-output --unbuffered "$FORMAT"	
}

# USAGE: command that prints json logs | jlog
