[jira] [Updated] (GROOVY-9845) Safe star dot operator

["rkrisztian (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-9845?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

rkrisztian updated GROOVY-9845:
-------------------------------
    Description: 
Currently I would have to write code like this (in the Groovy Console) to be safe:

{code:groovy}
def json = [
    messages: [
        [message: 'test']
    ],
    errors: null
]


[
    *(json.messages ? json.messages*.message : []),
    *(json.errors ? json.errors*.message : [])
].join('\n')
{code}

I would like to request for an operator like {{?\*.}} so I can write something like this:

{code:groovy}
[
    *(json.messages?*.message ?: []),
    *(json.errors?*.message ?: [])
].join('\n')
{code}

Not sure if it can be simplified further, but that's the idea.
