Problem

parse_key_value("aaa=bbb ccc", accept_standalone_key: false)

✅ could not parse whole line successfully

parse_key_value("aaa bbb=ccc", accept_standalone_key: false)

❌ {"aaa bbb": "ccc"}

parse_key_value("aaa= bbb=ccc", accept_standalone_key: false)

❌ {"aaa": "bbb=ccc"}

Context: unexpected output when using parse_logfmt(), which is a thin wrapper around parse_key_value().

Hi @pikeas !

For each of the second two examples, could you provide the output you expected?
