I started experimenting with calling a basic function from a python

to
a certain extent.

I am working on linux Mint.

I started with a basic Sub I found. In it's original form it had 3
rgb
values hard coded and it popped up a message box that displayed the
color value from the rgb input. I rewrote it as a Function that took
the
rgb values as parameters.

Here is the basic:

Function ColorExampleFunc(r as long, g as long, b as long)
Dim lVar As Long
lVar = rgb(207,231,245)
msgbox "The color " & lVar & " consists of:" & Chr(13) &_
"red= " & red(lVar) & Chr(13)&_
"green= " & green(lVar) & Chr(13)&_
"blue= " & blue(lVar) & Chr(13) , 64,"colors"

end function

Here is the python:

#test_basic.py
import os

result = os.system('soffice
"macro:///Standard.Module1.ColorExampleFunc(207,231,245)"')

This works as it will pop up the message box with the color value
displayed. What I need to do is capture that color value (which is
usually an eight digit number) in variable in the python script.

I printed result and it was equal to 0.

It's been a long time since I did anything in basic. I imagine I
would
have to get rid of the msgbox code and set the rgb values equal to a
variable and then return them, but I'm not sure how to do it.

Does anyone know how to get the color value in the python script?

Thanks, Jim




You need used MasterScriptProviderFactory

Change the original Basic function to:

Function ColorExampleFunc(r As Integer, g As Integer, b As Integer) As
Long
ColorExampleFunc = RGB(r, g, b)
end function

Then you can call, look my example:

Best regards


Mauricio,

Thanks for sharing your script with me. I ran it but got a Segmentation fault. I scattered some print()'s throughout the script and it looks like this is the line that may be causing the problem.

script = factory.createScriptProvider('').getScript(url) which is in the
def _call_macro_basic(location, args) function. Execution does not continue past that line.

I have been working on automating some of my worksheets using OOSheet. This means that I must start libreoffice calc like this:

libreoffice /home/jfb/Dev/Test_OOSheet.ods --accept="socket,host=localhost,port=2002;urp;StarOffice.ServiceManager"

Maybe this is why the script works for you and gives me the Segmentation fault. I am going to keep trying get it to work for me as I think it offers me the best chance of doing what I want to do.

Thanks, Jim
