MMM-PythonPrint customisation

[RobCee]

@sdetweil it may just be quicker for me to learn how to do what my python code does in .js
It probably isn’t that complex. It is only reading stuff from web services and reporting it locally. I had hoped I could skip that stage, but I guess there are no short-cuts.

[sdetweil]

@RobCee you can do most of the dev and test using a local file , outside of MM

xxx.js
then
node xxx.js

at least to get your main function working…

this code would work in the node helper

@sdetweil super. thanks for the pointer.

@sdetweil

the docker image karsten13/magicmirror:latest doesn’t contain python. Simplest solution for this is to use the fat image karsten13/magicmirror:fat, for more infos: https://khassel.gitlab.io/magicmirror/images/

[sdetweil]

@karsten13 thanks… the doc needs help tho

The difference between latest and fat is image size and installed

those words are not used above that sentence, and so didn’t mean anything to me…

I would propose adding in front of that sentence

There are two images of each type created

latest and fat 
docker pull image_name:latest 
or
docker pull image_name:fat 

and then I would add a new line between these sentences

debian packages. For most use cases the latest image is sufficient. 
Some modules need dependencies which are not includes in latest, e.g

@sdetweil

yes, the docs … no native english speaker so docs are always a struggle. Thanks for the hints, will update …

[sdetweil]

@karsten13 and I missed the latest/fat under the TAG column of your table… tldr(lol), my apologies

[RobCee]

@sdetweil I have started fresh and am still having the same issue.
New install of buster, fully updated.
Installed all the MM and node successfully.
MM runs as expected.
Checked that python and python3 are both available to the OS.
Added the MMM-PythonPrint to the modules dir.

This is my config section:

		{
			module:"MMM-PythonPrint",
			position:"center",
			disabled:false,
			config: {
				// name of the python process to execute (could be python3)
				pythonName: 'python',

@RobCee weird, sorry, typo… fixed

git pull to get the update

[RobCee]

@sdetweil I found another, just up from that one - you have a missing ‘t’ in this line

this.config.command=this.config.command.slice(his.config.pythonName.length)
