How to return an empty message

[fernandogmar]

Hello!

I am just trying to do this:

test = {  $num ->
    *[0]         
     [other]         No empty text
}

but it gets an error:

TypeError
Cannot read property 'undefined' of undefined

How can an empty string be returned?

You ran into two paper-cuts here, both of which we're currently working on :) Hopefully the next release of the syntax spec (0.5) will solve both of them!

First, it's currently required to indent all of the message's body, including the closing brace } on the last line of your example. This will be fixed by #42.

#63 has a recommendation on how to explicitly define empty-string values: {""}. It a placeable with an empty string inside. Consider the following snippet:

test =
    { $num ->
         [0] {""}
        *[other] No empty text
    }

You can see it live in the Playground (use the Config tab to change the value of $num).

Thanks {""} worked like a charm ;)

Glad to hear! I'm going to close this issue now. Feel free to open a new one if you have any other questions.
