STON UUID in the key

You need to set “allowComplexMapKeys” in StonReader to true for it to handle objects as keys.

 

| reader |

 

reader := STONReader new.

reader allowComplexMapKeys: true.

reader on: (STON toStringPretty: (Object new-> Morph new -> nil)) readStream.

 

reader next.

 

 

Best regards,

Henrik

Subject: [Pharo-users] STON UUID in the key

 

Why does this fail?

 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

STON fromString: (

    STON toStringPretty: (Dictionary with: UUID new -> nil)

)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

I would assume that if it can be serialized, then it should be also parsable.

 

Having scalars for keys is JSON (and JavaScript) limitation because it's stupid,

but if Smalltalk can have any hashable object for key (so any object), then it should be also possible to STON it in/out.

 

Would this be hard to change?
