Description
Describe the bug
I am attempting to use subparsers and the config_path option together, however, I cannot seem to get the config path to actually set the defaults. I have tried multiple "paths" in the json file for the config file, posted below, but non seem to work. I've tried to investigate myself and think that the issue might be because the subparser does not copy the defaults for the command attribute (which chooses the subparser).
To Reproduce
import logging
from simple_parsing import ArgumentParser, Serializable
@dataclass
class DoA(Serializable):
a_config: str = "taco"
"""
what does a want?
"""
def execute(self):
print(f'A says {self.a_config}')
@dataclass
class DoB(Serializable):
b_config: str = "pie"
"""
what does b want?
"""
def execute(self):
print(f'B says {self.b_config}')
@dataclass
class Subprogram(Serializable):
command: DoA | DoB
"""
Do A or B?
"""
def execute(self):
self.command.execute()
if __name__ == "__main__":
parser = ArgumentParser(add_config_path_arg=True)
parser.add_arguments(Subprogram, dest="sub")
# logging.basicConfig(level=logging.DEBUG,
# format="%(filename)s:%(lineno)s:%(name)s:%(message)s")
args = parser.parse_args()
sub: Subprogram = args.sub
with open('./mwe_config_out.json', 'w') as ofile:
sub.dump_json(ofile)
sub.execute()
Expected behavior
Running
python sp_mwe.py doa --config_path mwe_config.json
with sp_mew.py being the above source code and mwe_config.json containing either:
"sub": {
"command": {
"doa": {
"a_config": "taco cheese"
},
"dob": {
"b_config": "apple pie"
}
}
}
}
or
"sub": {
"command": {
"a_config": "taco cheese",
"b_config": "apple pie"
}
}
}
(I don't care which format, either would be fine) should produce the output
A says taco cheese
Actual behavior
Instead, using either of the json formats we get the default output of
A says taco
