Windows: executing a script that creates a class

[agerber85]

I have a FCMacro, 'threadclass.FCMacro' I developed a few years ago that defines a class called 'thread'. That was probably FC 0.17 or 0.19 on Windows 7, and now I'm on Windows 10. I'm pretty sure I would launch it from the console using basically exec('path/to/threadclass.FCMacro'), but I probably would have had to deal with the fact that Windows uses backlashes. Now whenever I try it with backslashes in the string, I get

SyntaxError: unexpected character after line continuation character

which makes sense, since my string has'\t' in it. I've tried using the "Macros..." dialog to launch it, but whenever I do that, FC acts like the class 'thread' has not been defined, so I'm not sure it is executing.

What's the most preferable way for me to go about executing this macro? If I think I might commonly use it, how can I have it launch every time Freecad opens, so that the class is always available?

there is a setting for that behaviour
uncheck "Run macros in local environment" in Preferences_Editor#Macro
