Scilab + TCL/TK
Very promising. I know where to spend my weekends now :). It is a gem. No matter how much I ask ChatGPT it never comes up with such suggestions. So, thank you!
I recommend the book by Ashok. https://wiki.tcl-lang.org/page/BOOK+The+Tcl+Programming+Lang...
Scilab has good bridge and Tcl lots of extensions
