Error: Reserved variable name?

Nick_Boyts · January 30, 2024, 3:52pm

This is a weird issue/bug that I just came across:

prefix does not seem to be a viable name for a variable. It returns an EOF error.

So far I’ve noticed the issue in 2.17, 2.18, and 2.19. Is there some hidden property or class that uses this name that I’m unaware of?

Looks to be a Parser error, but nothing obvious at first glance. We’ll file a task to look at it

prefix is a reserved keyword from the old DesignScript language syntax. We will clean this up. Thanks for pointing this out @Nick_Boyts!
