Wolfram Language Packages

Different behavior of Switch when moved inside a package?

Daniel Geisler

Posted 2 years ago

The following code runs as intended in Mathematica, but always runs the `switch` default value when moved into a package. Is there a problem with using a list as a `switch` argument in the Wolfram Language? Is there a more appropriate way to write this code for a Mathematica package? DebugSwitch[{classification_,algorithm_}]:= Module[{}, Echo[{classification,algorithm}]; Switch[{classification,algorithm}, {Parabolic,Native}, Echo["NativeParabolic[f,n,z,p,4]"], {Hyperbolic,Native}, Echo["NativeHyperbolic[f,n,z,p,4]"], {Parabolic,Symbolic}, Echo["SymbolicParabolic[f,n,z,p,4]"], {Hyperbolic,Symbolic}, Echo["SymbolicHyperbolic[f,n,z,p,4]"], _, Echo["Symbolic[f,n,z,p,4]"] ]; ]

      ];
