How to execute a setup script only ONCE ?

[ekianjo]

A very simple question, but I can't figure how this works with PNDs.


I have a program in python I want to port, that needs a setup.py script to be launched first to install the software - then the main.py can be used subsequently.


How would this work on Pandora ?


1/ is it possible to execute a setup script only once, and skip for subsequent program launches ?


2/ if not, should I try to integrate the setup commands in the actual main program to ensure the related actions are always properly followed?


Any help would be appreciated


Thanks.

The easiest way around this is to create a lock file when setting up then testing for its existance before running the setup again. If setup involves creating or copying any files to a non-volatile location you could check for their existance instead.

Another method is to check if a change that should have been done by the script (example a setting in a config file) is already in place and exit if it is. However, the method suggested by Neelix is better because you can force the script to re-run simply by deleting the lock file.
