doc for MMM-PythonPrint

• Clone this modules URL from github

• Edit config.js and add a block like this:

   {
   	module:"MMM-PythonPrint",
       position:"center middle",
   	disabled:false,
   	config: {
   		// name of the python process to execute (could be python3)
   		pythonName: 'python',
   		// command file in module folder
   		// if false, YOU will provide the full path to the python program
   		localfolder: true,
  
   		// spawn a python pgm that writes over and over (timed maybe), but keeps running
   		command: 'printit.py',
   		repetative: true,
  
   		// spawn a one time output  script, but relaunch it every cycletime milliseconds
  
   		// repretative: false,
   		// command: 'printitonce.py',
   		// cycletime: 2000,   // only used in repetative:false
                       // this is milliseconds
  
   		// print debugging messages from the node_helper
   		debug: true,
   		transform:(data)=>{return data.replace(/\n/g,"<br>")}
   	}
   }

this module can be used multiple times in config.js with different scripts and configuration

the transform function can convert the output of the python script in any way it chooses. if html content is in the resulting string, it is ok, as the module will insert it as html content always

The class PythonPrint is added to the css.

To change the color of the print, add to custom.css:

.MMM-PythonPrint .PythonPrint {
	color: red;
}

maybe your python script starts and runs, prints one line, and ends. current temp is x

is that all you want your module to present, one line?

or do you want the output every few seconds minutes

this is repetative:false, but my module will rerun the script every cycle time milliseconds

but some python scripts do that internally.

print, sleep, print, sleep, print, sleep, print…

this is repetative: true my module will just start the python script

there are two different ways to capture the output

should have named parm

script_is_long_running

I provided a sample of each

also, in many cases, you are using someone else’s script and don’t have control over how it works, and don’t want to rewrite it

if you need to pass parameters to your python script, they go as part of the command parameter, space separated

for example

   command:"printitonce.py this is a test of parms"
