Using Ternary Operators in Widget Expressions

Hi,

Just a quick note to let you know something I discovered by chance…

It has been established that when you make expressions in widgets using the ternary operator:

condition ? ifTrue : ifFalse

you have to enclose them with quotes because it doesn’t work otherwise:

So the solution would be indeed, adding quotes around the entire expression, which was always a bit clumsy:

It turns out the only reason you must do this is because of the spaces around the colon :. That’s because YAML will try to interpret it as another key.

So all these work without quotes around the expression if you accept the lack of spaces around the colon:

So, just letting you know - I would rather see no spaces around the colon instead of the entire expression enclosed in double quotes, I think. The added parentheses (2nd suggestion) can add more clarity.

Cheers,
Yannick

Thanks Yannick! This is a great discovery that can clean up a lot of the widget yaml.

Your efforts are appreciated, as always.
