3dsmaxbatch.exe Outputing text to console from python script

[8m0005]

I'm using 3dsmaxbatch.exe to run a python script:

3dsmaxbatch.exe script.py -mxsString string1:"InputPath" -mxsString string2:"OutputPath" -listenerlog Logfile.log

I see that 3dsmaxbatch.exe outputs some progress to the console window, and similar gets logged into the Logfile.log

Logfile.log also gets all the Print statements from the python script. 

Is it possible to output these print statements to the console window also, not just the log file?

have you tried sys.stderr in your print ? I've no idea if it works just a thought.

print("Hello World", file=sys.stderr)

That actually worked....in a way. Good beginning... 

print("Hello World", file=sys.stderr)

prints to the output, but because it is stderr, when the task is done it also tells me that it finished with errors

2/16/2023 15:55:27 PM;  Task Completed with Error(s) - see above

It would be nice if it didnt give me the "Errors present" message unless there are actual errors. 

If I use sys.stdout I still don't see anything....

have a look at logging perhaps ?

import logging 

logging.debug('This is a debug message')
logging.info('This is an info message')
logging.warning('This is a warning message')
logging.error('This is an error message')
logging.critical('This is a critical message')

I've tried using logging, and that does output the log message to the console, but it also prepends the log level name and root to the line:

logging.info('This is an info message')

INFO:root:This is an info message

and you still get the error message: 

Task Completed with Error(s) - see above

[klvnk]

could try....

logging.basicConfig(format='%(message)s', level=logging.INFO)

[8m0005]

I actually fixed the INFO:root: output with logging.basicConfig(format='%(message)s')

But I still get the error message.... and it seems that the logging does not respect the '\n' character. It might be using stderr in the background.

another way maybe to use win32gui and write your text directly to the window ?

Hm....That might conflict with whatever 3DS is doing to stdout. I believe it is somehow redirecting it.
