Hi Chris,

I’d like to add an assert() to some of our MWorks files ensuring they’re only run on a given build date of mworks, or later. Is there any way to do this now? If not, can you add to todo?

thanks!  
Mark

Hi Mark,

There isn’t a built-in way to do it. However, you could do it with a Python script, loaded as a [Python file resource](https://mworks.github.io/documentation/latest/components/python_file_resource.html). See the attached example.

I also could add a built-in method, if you’d prefer that.

Cheers,  
Chris
