MMM-PythonPrint customisation

[sdetweil]

@RobCee were you able to resolve the exec of the python script?

[RobCee]

@sdetweil I haven’t managed to get it running yet.
I did have some success (I had it printing Hello on the screen), but then the wheels came off and I have been unable to get it working again.

I have reverted to the default configuration from your Github page to try and wiork out what is going on, but I am seeing the following in the logs:

[11.04.2022 16:30.34.903] [LOG]   Connecting socket for: MMM-PythonPrint

Which seems to be the same error as before, but now I am not using any 3rd party modules, just the sample code.

@RobCee said in MMM-PythonPrint customisation:

ReferenceError: data is not defined

are u launching ‘python’ or python3?

the default
const python=‘python’

[RobCee]

@sdetweil I am using python3 and I have updated the two references to ‘python’ -> ‘python3’ to reflect this

[sdetweil]

@RobCee right, you don’t have to change the code, just use the config.js setting

{ 
module:
     config: {  
         pythonName:'python3',
    }
}

[RobCee]

@sdetweil ok, I will try it there then and see what happens.
Tracking down errors in this MM OS is fun…

[sdetweil]

@RobCee o, I see that I have a potential bug… if the command: is not configured,
it defaults to “”… oops…

I just pushed an update got that

git pull in the module folder

to debug

add debug: true

and then look where u start MM… (this doing npm start )

[11.04.2022 10:55.18.114] [LOG]   PythonPrint sending program output=hello

[RobCee]

@sdetweil I will have a go with that, but I think I have a slightly different problem of my own making.

[sdetweil]

@RobCee ok, I also fixed the use of the pythonName and added it to the debug message

I’m not sure why, as I did manage to get it working at one point, but I think the issue is that I am using the MM OS Docker image to run all this.
I think this means that the path expectations are different from the assumptions that I am making.
I may have to give in and just build the whole thing manually - it will probably be quicker than trying to fault find the install, given it’s obfuscation.
