[SOLVED] Modifying JQ filter to yield comma-delimited key-value pairs

Issue

I have the following bash script:

#!/bin/bash
js="{\"fizz\":\"buzz\",\"foo\":\"baz\"}"
echo $js

json=$(echo "$js" | jq -r "to_entries|map(\"\(.key)=\(.value|tostring)\")|.[]")

echo "fetching secret json:"
echo $json

When I run it I get this:

myuser@mymachine myapp % bash myscript.sh
{"fizz":"buzz","foo":"baz"}
fetching secret json:
fizz=buzz foo=baz

In reality the JSON will be a lot larger than just 2 properties, but it will be a flat mapping of key-value pairs (no object nesting).

I actually need these map entries in comma-delimited key-value pairs. So instead of:

fizz=buzz foo=baz

I need:

fizz=buzz,foo=baz

What can I do to my jq filters (or elsewhere) to get a comma inserted in between the key-value pairs? To be clear I'm not looking for valid JSON output, nor CSV format. I need comma-delimited KV pairs. Thanks in advance!

Solution

Just join them.

jq -r 'to_entries | map("\(.key)=\(.value)") | join(",")'
