Variables in Switch-Case

[jnsprnw]

Hey!
Thank you for the wonderful library!

Is it possible to use variables in switch-cases? I want to implement something in a similar way like this:

const text = 'I’m {age:number} years old{hasRegion|{true: from {region}, false:}}.';
const str = LLL(test, { age: 10, hasRegion: true, region: 'Asia' });

Expected output: I’m 10 years old from Asia.

const str = LLL(test, { age: 10, hasRegion: false });

Expected output: I’m 10 years old.

The output I get at the moment is I’m 10 years old{hasRegion|}..

Is that possible at all?

Hi, thanks for your kind words :)

No, this is currently not possible.

It is not the prettiest code, but you could do it like this:

const text = 'I’m {age:number} years old {appendix:string}'
const textAppendix = 'from {region}'
const region = 'Asia'
const str = LLL(text, { age: 11, appendix: region ? LLL(textAppendix, { region }) : '' }).trim()

Do you really use the raw LLL function with plain strings instead of the LL function with an dictionary object?

Ah, I see. I guess, it’s easier to just use two different templates depending on hasRegion.

And no, I’m using LL. This was just to quickly test multiple templates.
