Hello there.
This is what I'd like to achieve: let's say I have a script that I saved as
testScript.py, and it is located in the scripts folder, so that Maya can
find it. I want to add an icon to my custom shelf which, instead of running
the code of script, "loads" the script file and runs it. This would allow
me to edit the script and avoid substituting the code inside the custom
shelf icon.
Here is a code example:
# Load maya commands module
import maya.cmds as mc
# This prevents multiple windows to pop up
if mc.window("myWindow", ex=True):
mc.deleteUI("myWindow", window=True)
# Window set-up
mc.window("myWindow",title="Test Window", s=False, wh=(300,100))
mc.columnLayout(adj=True)
toggle_test = mc.checkBox(label = 'Toggle me!', value = False)
mc.button(l="Press to print the value of the checkbox below", w=300, h=100,
command = 'printIt()'
)
mc.showWindow("myWindow")
# Print the value
def printIt():
# Query toggle status
var = mc.checkBox(toggle_test, query = True, value = True )
# Print the status
print "Checkbox's status is:", var
The code runs fine if selected and executed in the script editor. I created
a shelf button with the following code:
import testScript
reload (testScript)
After restarting maya, or deleting the global instance of the printIt
function, if I click on the shelf button the script runs and the UI is
shown. If I then click on the UI button, I get the following error:
# Error: NameError: file <maya console> line 1: name 'printIt' is not
defined #
Ok, I get what is happening. The button press is running the code
'printIt()', but the function has not been imported in global space (I
might be throwing wrong terms around a bit, please correct me if that
happens) and it can't be found.
I am willing to edit the script, but I want it to work both by importing it
or running it from the script editor. First option is to edit the shelf
button code to:
from testScript_01 import *
import testScript
reload (testScript)
This seems to work fine, but as I understand is not the suggested way of
solving the problem.
I could also edit
command = 'printIt()'
to
command = 'testScript.printIt()'
but this would have to side effects: first, if the script file is renamed
or imported as something else, the function would not work anymore. Second,
running the code inside the script editor would not work anymore.
So, any idea on how I could fix this issue? Is there a way I could feed the
proper filename to the code?
Something like:
import testScript
reload (testScript)
# Add a line of code that feeds the string 'testScript' to the imported
module
that then could be used inside the script as:
# Declare var for fed string
input_string = #fed string
...
command = input_string + '.printIt()'
Hopefully I managed to explain the issue properly :P
Thanks in advance!
