Multiple NeoJSON mappings for the same domain object

by Esteban Maringolo

Hi all, Sven, :) I'm working on a domain model that will have different JSON representations for the same domain objects, so depending on the context it will return one representation or another. In the past to solve the multiple representations, what I did was to build "helper" methods that added the mappings to the mapper. So the process was like: 1. instantiate the mapper 2. call a #neoJsonSimple: mapper 3. configure the mapper by calling other mapping defining methods 4. convert the object to a JSON string. If I wanted an "extended" representation, in the step 2 I would call #neoJsonExtended: instead. But I find this "too manual" to scale. So... is there a better, Â¿canonical?, way to achieve this? Thanks! ps: By now it will be only object -> JSON (so NeoJSONWriter), but in the future I might need to instantiate objects back from JSON, so the mappings should be for both mappers. Esteban A.

Its odd you can't have our own git project called MyProject/Pharo!

by Tim Mackinnon

Iâm really quite stunned that having worked happily 6 months ago on a project called github://exercism/pharo <github://exercism/pharo> (a name given to us by the exercism project) - that you canât load that code into Pharo7 anymore either via iceberg or via metacello. It looks like iceberg ignores any paths leading up to a project name and just assumes anything ending in pharo is the actual pharo project. It would be good to get confirmation of this - and also understand what would happen if any other projects happen to collide with each other - e.g. macta/StateSpecs vs google/StateSpecs? Its innocently done - and given we donât currently use prefixes on our project names - we could get a nasty surprise (if Iâve understood the implications correctly). It seems weird that we would do this though, so Iâm wondering if Iâve misunderstood this - hopefully? Can anyone more in the know comment? If it is true, its going to be embarrassing to have to go back to the exercism project (which just recently got funding from the Mozilla foundation) and ask them to change the name of our project to pharo-st because we canât handle the name...

Re: [Pharo-users] Traits for class methods?

by Hilaire

Thanks for the update. Took a look at the doc bellow. To my taste, this traits design really add complexity in the code, particularly in responsibility and now the state. While it could be useful in some situation.
