[Question] Reading from a file

[mantielero]

I have some data stored as msgpack file in python. The file contains more than 250columns.

In order to read the file, do I need to create a type that holds the data? Is there a workaround for that? I mean, something that creates that type definition from the file structure.

[jangko]

var s = newFileStream("somefile.m", fmRead)
var x = s.toAny()

it will create a dynamic msgpack structure in memory.
then use msgpack2any API to interrogate the content as you wish.

code generation? no
