Redberry is written in Java, which has no REPL and no operator overloading. They solved these issues by providing bindings to Groovy, which is somewhat a sort of scripted version of Java, extending Java to support a REPL and operator overloading. Their code is really interesting, they have already implemented many cases of manipulations of indexed quantities, including derivatives, derivatives of summations of indexed quantities, valence-sensitivity (i.e. covariant vs contravariant indices). They suggest to use IntelliJ IDEA as an IDE to work with Redberry, its great advantage over IPython is the ability to search for class locations and automatically import them. For the rest I prefer IPython notebook. -- You received this message because you are subscribed to the Google Groups "sympy" group.
