Re: simply python modules question

Hi there Python XSI'ers

I have been running into some similar update things for the last 8 months on our current project and the modules will not not refreshed unless the file has changed since the last reload command.  The XSI Active Python implementation does some rather funky things with its caching of modules that are not the same as the way Python does things.

The best way to negate the issues in my case were to always use the reload command directly after each import command and to also make sure modify all of the .py files you are accessing for your plugin/script before running it after a code change.

In linux it is easy to set up some kind of deploy script that just does a touch command on all of the necessary files so that XSI will refresh them when it encounters them.

Another thing that sometimes works is deleting all of the .pyc files, so that python is forced to generate them again, this is some rare cases also fixes some bizarre issues.

cheers,

Luke

I'm looking into using the reload solution as well as some other promising
solutions.  If I get good results with the others I'll post info here.

hi brad,
I think you mis-interpreted what Patrick said or I have mis-interpreted what
you want.
He IS talking about the module and not the command.
When you import the module you just follow that with a 'reload()' and your
changes will all come through.



#####
import sys

# update your python paths if the folder that you 'know' the module to be in
is not in the path.
someFolder = 'whatever/and/ever
if someFolder not in sys.path :
sys.path.append( someFolder )


#import the module
import mymodule
reload( mymodule )

#import any specifice from the module
from mymodule import myModuleFunction
reload( myModuleFunction )


mymodule.sumething() etc. etc

cheers,
phil b

No, I kept it a good old normal command. So changes to the actual command
.py
file do update immediately... unlike with a self installed plugin in which
I
would have to reload it. Its the modules referenced from the command .py
file
with an import statement that are not updating.

How is the command built, through a self-installing plugin?

Subject: simply python modules question

Hi,

I've got a command that's importing a custom python module.

I've added the package to the PYTHONPATH variable and it runs.

However, if I open the module, make a change, and save it, I
have to restart XSI in order for the change to make it into
the XSI execution environment.

Is there a well known and accepted way to have the XSI python
execution evironment flush the module from memory and reload
it from the new source without having to restart XSI?

Before I spend hours trying to work around this myself, I
thought I'd check with the minds on the list. I'm fairly new
to Python.

Thanks.

-brad
