Feature Request: Serialize Aggregation for use with Hops components

[s7uvx]

Hi Andrea, it would be tremendously beneficial to be able to send aggregations to and from Hops components, as this would open up parallel computing for Wasp - I know that there is a save to file method that I could use, but thought I would ask you to expose the JSON encoded aggregation which can then be used as a String to send to a hops component?

Hi,

each class in Wasp has a serialization and deserialization method (with the exception of Attributes), respectively called "to_data" and "from_data". This returns a python dictionary already formatted to be converted to a JSON file. So, it should be possible to use a python component and call the .to_data() method on the aggregation object in order to serialize. Let me know if you need help with setting that up.

Thanks Andrea, I'll try this.

OK, I think I have something workable: PART_OUT to TXT:

import sys
import os
import Rhino.Geometry as rg
import Grasshopper as gh
import json

## add Wasp install directory to system path
wasp_loaded = False
ghcompfolder = gh.Folders.DefaultAssemblyFolder
if ghcompfolder not in sys.path:
    sys.path.append(ghcompfolder)
try:
    from wasp import __version__
    wasp_loaded = True
except:
    msg = "Cannot import Wasp. Is the wasp folder available in " + ghcompfolder + "?"
    ghenv.Component.AddRuntimeMessage(gh.Kernel.GH_RuntimeMessageLevel.Error, msg)

## if Wasp is installed correctly, load the classes required by the component
if wasp_loaded:
    from wasp.core import Aggregation

TXT = json.dumps(PART_OUT.to_data())

TXT to PART_OUT

import sys
import os
import Rhino.Geometry as rg
import Grasshopper as gh
import json

## add Wasp install directory to system path
wasp_loaded = False
ghcompfolder = gh.Folders.DefaultAssemblyFolder
if ghcompfolder not in sys.path:
    sys.path.append(ghcompfolder)
try:
    from wasp import __version__
    wasp_loaded = True
except:
    msg = "Cannot import Wasp. Is the wasp folder available in " + ghcompfolder + "?"
    ghenv.Component.AddRuntimeMessage(gh.Kernel.GH_RuntimeMessageLevel.Error, msg)

## if Wasp is installed correctly, load the classes required by the component
if wasp_loaded:
    from wasp.core import AdvancedPart

PART_OUT = AdvancedPart.from_data(json.loads(TXT))

Just FYI I can't recover some of the attributes on the other end, any pointers would be appreciated.

As mentioned above, Wasp Attributes are currently the only Wasp class that does not support serialization. That means that Attributes will be ignored when serializing a Part or an Aggregation. This is due to the fact that Wasp Attributes support virtually any kind of data, which makes it challenging to have a serialization method able to support all these types.
