ifcopenshell validate How to output legal json

C by CadGiru on 19 Oct 2022, edited 19 Oct 2022 #

when using json_logger with this sample script


outfile = open(target_file, "wb")  # /path/file.ifc

json_logger = ifcopenshell.validate.json_logger()

ifcopenshell.validate.validate(ifc_file, json_logger)

original_stdout = sys.stdout  # Save a reference to the original standard output

print(f"original_stdout\n{original_stdout}")

with open(target_file, 'w') as outfile:

    sys.stdout = outfile  # Change the standard output to the file we created.

    print(json_logger.statements)

    sys.stdout = original_stdout  # Reset the standard output to its original value

    outfile.close()

print(json_logger.statements)

Output from json_logger.statements is single line / single quoted


[{'level': 'error', 'message': 'Attribute <entity IfcFurnitureType>.<attribute AssemblyPlace: <enumeration IfcAssemblyPlaceEnum: (FACTORY, NOTDEFINED, SITE)>> not optional', 'instance': #12552 .........................

so question is HowTo get output as valid json file?

Does anyone know if there's a way to serialize full ifcopenshell entities?

@CadGiru what do you want a json for? if you don't need to reconstruct the objects, but just want to store the info in a file, you could just store the string representation of the entities:


import json


# your previous code


statements = json_logger.statements

for statement in statements:

    statement['instance'] = str(statement['instance'])


with open('/path/to/file.json', "w") as f:

    json.dump(statements, f, indent=4)

@cvillagrasa Corect, however I need to reconstruct the objects for further processing...
