Space in Key for Custom JSON Object ?
adamency opened this issue · comments
I can't figure out how to declare a key in my custom JSON object with spaces in the name:
> aws ec2 describe-instances --query "Reservations[].Instances[].{Name: Tags[?Key == 'Name'].Value | [0], Id: InstanceId, State: State.Name, 'Public IP': PublicIpAddress, Type: InstanceType}" --output table
Bad value for --query Reservations[].Instances[].{Name: Tags[?Key == 'Name'].Value | [0], Id: InstanceId, State: State.Name, 'Public IP': PublicIpAddress, Type: InstanceType}: Expecting: ['quoted_identifier', 'unquoted_identifier'], got: literal: Parse error at column 103, token "Public IP" (LITERAL), for expression:
"Reservations[].Instances[].{Name: Tags[?Key == 'Name'].Value | [0], Id: InstanceId, State: State.Name, 'Public IP': PublicIpAddress, Type: InstanceType}"
Absolutely nothing to be found online about this, as all threads in search results deal with spaces in keys from the object we're querying from, not the object we're creating.
I have tried with backticks, single quotes, double quotes, escaped single & double quotes, quoted quotes, etc... nothing seems to work.
Double quotes is the right way to go about this, however this seems like an issue with the AWS cli rather than the JMESPath libraries.
This works just fine:
{ "public ip": @.my.object }
Yep, it's double quotes for keys with spaces in them (anything that doesn't qualify as a unquoted idenfitifer), and for CLI you'll need to make sure you're escaping the quotes in your shell. A quick way to double check the quoting is to prefix the command with echo, which will show you how the value the CLI receives. Note the escaped \"
here:
~ $ echo aws ec2 describe-instances --query "Reservations[].Instances[].{Name: Tags[?Key == 'Name'].Value | [0], Id: InstanceId, State: State.Name, \"Public IP\": PublicIpAddress, Type: InstanceType}" --output table
aws ec2 describe-instances --query Reservations[].Instances[].{Name: Tags[?Key == 'Name'].Value | [0], Id: InstanceId, State: State.Name, "Public IP": PublicIpAddress, Type: InstanceType} --output table
