Problematic

I want to import my script to my project. with this method the project will be more maintainable and we will be more efficient to split the code to different file. Python have implement this features and you check the documentation here

(modules)Project arborescence :
└── project  
    ├── exemple1  
             ├── testFunction.py  
    ├── main.py  

Working on Vs code debug but not in maya

from exemple1.testFunction import test

test()

Maya and path not a good love storie

In maya when you import a script, the relative path is not taken into consideration. The path is ovewriden by the path script of maya. We can check it with the library pathlib

Solution

First we must put our project scipt in the maya folder script. For me it's here :

C:/Users/Gilles/Documents/maya/2022/scripts

Then we must force it to the path of our project.

import maya.cmds as cmds
import sys 

def importMayaScript(nameFolder):

    # allows to recover le path du folder scrit
    myScriptDir = cmds.internalVar(userScriptDir=True)
    setScriptDir = myScriptDir+'project/src/'+str(nameFolder)+'/'
    
    sys.path.append(setScriptDir) 

I use the library sys to add the path to my import library.

We will use this method to have the path of the scirpt folder:

Internal Var

Then we use sys.path.append(setScriptDir) to make append the module to our library project.

importMayaScript("exemple1")      

from testFunction import test

test()

Now it's working !

Now we use our python files as components ! Example of use :
