Sc link is broken

I wish I could help, but my level of skill in C + + is very basic now.
I'm still trying to understand how all the various classes interact with each other.
And how and where in the code checks are performed.
P. S. The editor for the script is functional, but extremely thin and not very flexible.
It does not allow for example to export and import text.
So it is often time-consuming do experiments.
Is there some other way to edit the script?
