Trying to split script up across more then one file

Coding Python Support
1

I have two files …

b.py


def showsomething():
	print("this is b.py")

and

test.py


print("this is file test.py")
showsomething()

How on earth do I get test.py to use the code in b.py?

2

Heh, figured it out…


import sys
import os
import bpy

blend_dir = os.path.dirname(bpy.data.filepath)
if blend_dir not in sys.path:
   sys.path.append(blend_dir)

import b
import imp
imp.reload(b)
b.showsomething()

lets test see b

Is there a better way/proper way of doing this? - what I found does not feel clean!

I would like to code this python script in an external editor and spread it across a number of files for ease of development.

That’s pretty much how it’s done… aside from the imp.reload part which is totally not needed.

You can also take a look at ‘modules’ on the python.org docs.

imp.reload() is there so blender does not keep hold of the external file I might be changing

this is my solution
chanbe test.py so:


import b
print("this is file test.py")
b.showsomething()

Running gives:
C:\BlenderSVN\cmake_all3\bin\2.62\scripts\addons\Ephestos>python test.py
this is file test.py
this is b.py

C:\BlenderSVN\cmake_all3\bin\2.62\scripts\addons\Ephestos>

blah.py


def yada():
    print(42)

with blah in modules folder:


from blah import yada

with blah in same folder (init perhaps):


from .blah import yada
