tdu.collapsePath: What should be returned when inputting the project root path?

Bugs
1

Hey there,

It seems that the returned value for tdu.collapsePath when inputting the project root path did change.

In version 2018.27840 this returns “$TOUCH”
In version 2020.20625 this returns the inputted project root path.

I could not find a documentation that this behaviour changed in the Changelog. So it’s either a bug or the change was not documented. Or a behaviour that was never documented and some people relied on :wink:

How did I find this issue?
@raganmd 's save external component uses a check to $TOUCH to determine if the path is at the project root. So it now puts an absolute path for all saved components.

Nice catch here @manuel_mitasch. Does that save external component need to be updated as well?

@raganmd Yes, I guess changing that check would make sense. I think the check can simply be changed from “$TOUCH” to project.folder. The path handling afterwards would need small changes.

If you want I can make a PR on github.

Sorry about this. Yes $TOUCH is a TScript variable so tdu.collapsePath should never have been returning that :frowning:
