Display list of data classes as table

[mwisnicki]

A list of data classes should be rendered as a table like the DataFrame rather than simple toString()

[mwisnicki]

This gets me close to what I want (although columns are ordered lexicographically rather than as defined in data class constructor) but IMHO should be default behavior:

%use krangl
someListOfDataClasses.asDataFrame()

This one will require a compiler plugin since it is not possible to decompose a generic data class (or any other class) without it. It could be done with a serialization plugin and would work for and any class marked as @Serializable.

@mwisnicki You can achive the same thing using dataframe library. But I don't think it should be a default behaviour

[ileasile]

@altavir in case of data classes (which we can check in RT with KClass<*>.isData) all the constructor arguments are properties, and we can get all constructor arguments in the proper order: KClass<*>.primaryConstructor?.parameters. Some properties that are not present in primary constructor have a chance to stay unordered but it is generally acceptable

I will close this issue. I've created the issue in dataframe about this problem: Kotlin/dataframe#32
